Extravasation of Diagnostic and Therapeutic Materials
Evans Blue
Capillary Permeability
The property of blood capillary ENDOTHELIUM that allows for the selective exchange of substances between the blood and surrounding tissues and through membranous barriers such as the BLOOD-AIR BARRIER; BLOOD-AQUEOUS BARRIER; BLOOD-BRAIN BARRIER; BLOOD-NERVE BARRIER; BLOOD-RETINAL BARRIER; and BLOOD-TESTIS BARRIER. Small lipid-soluble molecules such as carbon dioxide and oxygen move freely by diffusion. Water and water-soluble molecules cannot pass through the endothelial walls and are dependent on microscopic pores. These pores show narrow areas (TIGHT JUNCTIONS) which may limit large molecule movement.

Surgical treatment of internal carotid artery anterior wall aneurysm with extravasation during angiography--case report. (1/263)
A 54-year-old female presented subarachnoid hemorrhage from an aneurysm arising from the anterior (dorsal) wall of the internal carotid artery (ICA). During four-vessel angiography, an extravasated saccular pooling of contrast medium emerged in the suprasellar area unrelated to any arterial branch. The saccular pooling was visualized in the arterial phase and cleared in the venophase during every contrast medium injection. We suspected that the extravasated pooling was surrounded by hard clot but communicated with the artery. Direct surgery was performed but major premature bleeding occurred during the microsurgical procedure. After temporary clipping, an opening of the anterior (dorsal) wall of the ICA was found without apparent aneurysm wall. The vessel wall was sutured with nylon thread. The total occlusion time of the ICA was about 50 minutes. Follow-up angiography demonstrated good patency of the ICA. About 2 years after the operation, the patient was able to walk with a stick and to communicate freely through speech, although left hemiparesis and left homonymous hemianopsia persisted. The outcome suggests our treatment strategy was not optimal, but suture of the ICA wall is one of the therapeutic choices when premature rupture occurs in the operation. (+info)Effect of alpha-trinositol on interstitial fluid pressure, oedema generation and albumin extravasation in experimental frostbite in the rat. (2/263)
1. The anti-inflammatory effect of alpha-trinositol (D-myo-inositol-1,2,6-trisphosphate) on oedema formation, microvascular protein leakage and interstitial fluid pressure (Pif) in rat skin after frostbite injury, was investigated. Alpha-trinositol (40 mg kg body weight(-1)) was administered intravenously as a bolus both before and/or in the interval between freezing and thawing of the tissue. 2. Pif was measured in rat paw skin with micropipettes connected to a servo-controlled counterpressure system. Oedema formation was estimated by measuring the increase in total tissue water content (wet weight minus dry weight divided by dry weight). Albumin extravasation (i.e., the difference between the plasma equivalent space for 125I- and 131I-human serum albumin (HSA) circulating for different time intervals) was used to estimate the microvascular leakage. 3. Compared to untreated animals, alpha-trinositol given pre- and/or post-freeze reduced total tissue water and albumin extravasation as well as the fall in Pif in injured tissue significantly (P<0.05). Alpha-trinositol given only post-freeze reduced total tissue water and albumin extravasation from 4.46+/-0.93 and 2.37+/-1.12 to 2.51+/-0.29 and 0.36+/-0.18 ml g dry weight(-1), respectively (P<0.05). 4. Pif fell from -0.8+/-0.2 mmHg pre-freeze to -3.4+/-1.0 mmHg (P<0.05) at 20 min after tissue injury (circulatory arrest) and was attenuated by treatment with alpha-trinositol. 5. We conclude that alpha-trinositol exerts its anti-oedematous effect by acting on the extracellular matrix, attenuating the lowering of Pif as well as on the microvascular wall, thereby decreasing the protein extravasation. (+info)Cellular expression of green fluorescent protein, coupled with high-resolution in vivo videomicroscopy, to monitor steps in tumor metastasis. (3/263)
High resolution intravital videomicroscopy has provided a powerful tool for directly observing steps in the metastatic process, and for clarifying molecular mechanisms of metastasis and modes of action of anti-metastasis therapeutics. Cells previously have been identified in vivo using exogenously added fluorescent labels, limiting observations to a few cell divisions, or by natural markers (e.g. melanin) expressed only by specific cell types. Here we tested the utility of stable green fluorescent protein (GFP)-transfected cells for monitoring and quantifying sequential steps in the metastatic process. Using CHO-K1 cells that stably express GFP, we document the visualization and quantification by intravital videomicroscopy of sequential steps in metastasis within mouse liver, from initial arrest of cells in the microvasculature to the growth and angiogenesis of metastases. Individual, non-dividing cells, as well as micro- and macrometastases could clearly be detected and quantified, as could fine cellular details such as pseudopodial projections, even after extended periods of in vivo growth. We quantified the size distribution of micrometastases and their locations relative to the liver surface using 50 micrometer thick formalin-fixed tissue sections. The data suggest preferential growth and survival of micrometastases near the liver surface. Furthermore, we observed a small population of single cells that persisted over the 11 day observation period, which may represent dormant cells with potential for subsequent proliferation. This study demonstrates the advantages of GFP-expressing cells, coupled with real-time high resolution videomicroscopy, for long-term in vivo studies to visualize and quantify sequential steps of the metastatic process. (+info)Role of angiotensin II in modulating the hemodynamic effects of nitric oxide synthesis inhibition. (4/263)
This study examined the role of ANG II in modulating the increase of hematocrit and vascular permeability that follows nitric oxide (NO) synthesis blockade, that are contributing to the decrease in cardiac index (CI) in conscious, chronically catheterized rats. Pretreatment with losartan attenuated the N(omega)-nitro-L-arginine methyl ester (L-NAME)-induced increase in total peripheral resistance by 26% and also blunted the fall in CI (28%) and stroke volume. L-NAME produced an increase in hematocrit (4.5%) and in (125)I-labeled albumin content in the heart and small intestine in untreated rats, but the increase was prevented in rats pretreated with losartan. Furthermore, L-NAME induced a transient increase of plasma protein concentration and tissue intestinal blood flow, which was abolished in rats given losartan. The results of the present study indicate that the systemic hemodynamic responses, the fall in plasma volume, and the increase in albumin escape observed after inhibition of NO synthesis are in part the consequence of unmasking the actions of endogenous ANG II. These data suggest a physiological role for NO by restraint of the vascular actions of the renin-angiotensin system. (+info)Intraventricular contrast medium leakage during ethanol embolization of an arteriovenous malformation. (5/263)
We report the unusual phenomenon of abrupt intraventricular contrast medium leakage from the choroid plexus occurring during ethanol embolization of a periventricular arteriovenous malformation. There was no evidence of any associated intraventricular hemorrhage to suggest that leakage arose from a vessel perforation, as was first suspected. Intraventricular contrast medium leakage has been reported previously in the setting of ependymitis, and it is likely that similar pathogenetic mechanisms apply in this case. To our knowledge, this is the first reported case of intraventricular contrast medium leakage occurring during an embolization procedure. (+info)Thrombosed dissection of the ascending aorta complicating extravasation. (6/263)
This report presents 2 patients with thrombosed dissection of the ascending aorta complicating extravasation. The first case was an 85-year-old male admitted with shock due to cardiac tamponade. Plain computed tomography (CT) demonstrated a dilated ascending aorta without clear evidence of aortic dissection. The second case was a 77-year-old female presenting with shock, in whom an enhanced CT scan demonstrated a dilated ascending aorta and periaortic effusion. However, dissection of the distal ascending aorta was not identified in either case before emergency surgery. In case 1, soon after the bloody pericardial effusion was decompressed during the operation, bleeding from the ascending aorta occurred. A small intimal tear was found in the distal ascending aorta, and in each case the pseudolumen was filled with fresh thrombus. The ascending aorta was replaced. Each patient had an uneventful postoperative recovery. Based on this experience, it is suggested that patients with thrombosed ascending aortic dissection complicating extravasation should undergo early graft replacement. (+info)Scanning electron microscopic studies on the route of neutrophil extravasation in the mouse after exposure to the chemotactic peptide N-formyl-methionyl-leucyl-phenylalanine (fMLP). (7/263)
The present study was performed to demonstrate three-dimensionally the process of neutrophil extravasation induced by the bacterial chemotactic peptide N-formyl-methionyl-leucyl-phenylalanine (fMLP) in mice. Thirty to 40 min after the injection of fMLP to the mouse lip, the tissues were fixed with glutaraldehyde and examined by scanning electron microscopy (SEM) as well as by transmission electron microscopy (TEM). Observation of fMLP-injected tissues showed many neutrophils adhering to the inner wall of postcapillary venules. Some of these adherent neutrophils attached to each other to form groups of two to six. There were also many neutrophils migrating through the endothelium. Most of these neutrophils took a transcellular route, in that they penetrated the cytoplasm of the endothelial cells. The junction of two neighboring endothelial cells did not open, and endothelial pores free from migrating neutrophils were scarcely observed. There were bulging portions on the vascular wall which were probably produced by the presence of underlayed neutrophils. Thus, the present study gave direct evidence of neutrophil migration via a transcellular route in response to fMLP. Our findings also indicate that the pores of the endothelium close quickly after neutrophil extravasation. (+info)Three pathways between the sacroiliac joint and neural structures. (8/263)
BACKGROUND AND PURPOSE: Despite ongoing clinical suspicion regarding the relationship between sacroiliac joint (SIJ) dysfunction and lower extremity symptoms, there is a paucity of scientific literature addressing this topic. The purpose of this study was to describe patterns of contrast extravasation during SIJ arthrography and postarthrography CT in patients with lower back pain and to determine whether there are pathways of communication between the SIJ and nearby neural structures. METHODS: Fluoroscopically guided SIJ arthrography was performed on 76 SIJs. After the injection of contrast medium, anteroposterior, lateral, and oblique radiographs as well as 5-mm contiguous axial and direct coronal CT images were obtained. Contrast extravasation patterns were recorded for each joint. These observations included a search for contrast extravasation from the SIJ that contacted nearby lumbosacral nerve roots or structures of the plexus. RESULTS: Sixty-one percent of all joints studied revealed one of five contrast extravasation patterns. Three of these observed patterns show a pathway of communication between the SIJ and nearby neural structures. These included posterior extravasation into the dorsal sacral foramina, superior recess extravasation at the sacral alar level to the fifth lumbar epiradicular sheath, and ventral extravasation to the lumbosacral plexus. CONCLUSION: Three pathways between the SIJ and neural structures exist. (+info)Anemarrhena is a genus of perennial herbaceous plants belonging to the family Asphodelaceae, which includes the medicinal species A. asphodeloides (Zhong-Wei-Mu or Zhi Mu), traditionally used in Chinese medicine for treating various conditions such as fever, cough, and diabetes, due to its antipyretic, expectorant, and hypoglycemic properties.
Anemarrhena is a plant genus that belongs to the family Asphodelaceae. It includes several species, but the most commonly referenced one in medical contexts is Anemarrhena asphodeloides, also known as Zhong Wei Zi in traditional Chinese medicine.
The root of Anemarrhena asphodeloides has been used in traditional Chinese medicine for centuries to treat various health conditions, such as fever, cough, and diabetes. The active components of this plant include steroidal saponins, which have been shown to possess anti-inflammatory, antioxidant, and immunomodulatory properties. However, more research is needed to fully understand the potential medical applications and safety profile of Anemarrhena.
Extravasation of diagnostic and therapeutic materials refers to the unintended leakage or escape of these substances from their intended vessel or site into the surrounding tissues, which can lead to local adverse effects or complications.
Extravasation of diagnostic and therapeutic materials refers to the unintended leakage or escape of these substances from the intended vasculature into the surrounding tissues. This can occur during the administration of various medical treatments, such as chemotherapy, contrast agents for imaging studies, or other injectable medications.
The extravasation can result in a range of complications, depending on the type and volume of the material that has leaked, as well as the location and sensitivity of the surrounding tissues. Possible consequences include local tissue damage, inflammation, pain, and potential long-term effects such as fibrosis or necrosis.
Prompt recognition and management of extravasation are essential to minimize these complications. Treatment may involve local cooling or heating, the use of hyaluronidase or other agents to facilitate dispersion of the extravasated material, or surgical intervention in severe cases.
Evans Blue is a dye that, when bound to albumin, can be used diagnostically to estimate the volume of extravascular space or to detect blood-brain barrier disruption, as it only leaks into the brain parenchyma upon damage to its integrity.
Evans Blue is not a medical condition or diagnosis, but rather a dye that is used in medical research and tests. It is a dark blue dye that binds to albumin (a type of protein) in the bloodstream. This complex is too large to pass through the walls of capillaries, so it remains in the blood vessels and does not enter the surrounding tissues. As a result, Evans Blue can be used as a marker to visualize or measure the volume of the circulatory system.
In research settings, Evans Blue is sometimes used in studies involving the brain and nervous system. For example, it may be injected into the cerebrospinal fluid (the fluid that surrounds the brain and spinal cord) to help researchers see the distribution of this fluid in the brain. It can also be used to study blood-brain barrier function, as changes in the permeability of the blood-brain barrier can allow Evans Blue to leak into the brain tissue.
It is important to note that Evans Blue should only be used under the supervision of a trained medical professional, as it can be harmful if ingested or inhaled.
Capillary permeability refers to the ability of fluids (plasma), solutes, and cells to pass through the capillary walls, which is regulated by the size of the pores and the charge and hydrophilicity of the molecules involved, playing a crucial role in maintaining fluid balance and nutrient exchange between blood and tissues.
Capillary permeability refers to the ability of substances to pass through the walls of capillaries, which are the smallest blood vessels in the body. These tiny vessels connect the arterioles and venules, allowing for the exchange of nutrients, waste products, and gases between the blood and the surrounding tissues.
The capillary wall is composed of a single layer of endothelial cells that are held together by tight junctions. The permeability of these walls varies depending on the size and charge of the molecules attempting to pass through. Small, uncharged molecules such as water, oxygen, and carbon dioxide can easily diffuse through the capillary wall, while larger or charged molecules such as proteins and large ions have more difficulty passing through.
Increased capillary permeability can occur in response to inflammation, infection, or injury, allowing larger molecules and immune cells to enter the surrounding tissues. This can lead to swelling (edema) and tissue damage if not controlled. Decreased capillary permeability, on the other hand, can lead to impaired nutrient exchange and tissue hypoxia.
Overall, the permeability of capillaries is a critical factor in maintaining the health and function of tissues throughout the body.
'Materials testing' in a medical context refers to the process of scientifically examining and experimenting with materials used in medical devices, procedures, or environments, to evaluate their performance, safety, durability, and biocompatibility, ensuring they meet required standards and regulations.
I'm happy to help! However, I must clarify that "materials testing" is not a medical term per se. It is a term used in various fields, including engineering and materials science, to describe the process of subjecting materials to different tests to evaluate their properties and performance under various conditions.
In the context of medical devices or implants, materials testing may refer to the evaluation of the physical and mechanical properties of materials used in their construction. These tests can include assessments of strength, durability, biocompatibility, and other factors that are critical to ensuring the safety and efficacy of medical devices.
Medical device manufacturers must comply with regulatory standards for materials testing to ensure that their products meet specific requirements for performance, safety, and quality. These standards may vary depending on the type of device, its intended use, and the country or region in which it will be marketed and sold.
'Sensitivity' refers to the proportion of actual positives that are correctly identified by a test, while 'Specificity' denotes the fraction of true negatives accurately recognized by the same test, both measured in terms of true positive and true negative rates in diagnostic testing.
Sensitivity and specificity are statistical measures used to describe the performance of a diagnostic test or screening tool in identifying true positive and true negative results.
* Sensitivity refers to the proportion of people who have a particular condition (true positives) who are correctly identified by the test. It is also known as the "true positive rate" or "recall." A highly sensitive test will identify most or all of the people with the condition, but may also produce more false positives.
* Specificity refers to the proportion of people who do not have a particular condition (true negatives) who are correctly identified by the test. It is also known as the "true negative rate." A highly specific test will identify most or all of the people without the condition, but may also produce more false negatives.
In medical testing, both sensitivity and specificity are important considerations when evaluating a diagnostic test. High sensitivity is desirable for screening tests that aim to identify as many cases of a condition as possible, while high specificity is desirable for confirmatory tests that aim to rule out the condition in people who do not have it.
It's worth noting that sensitivity and specificity are often influenced by factors such as the prevalence of the condition in the population being tested, the threshold used to define a positive result, and the reliability and validity of the test itself. Therefore, it's important to consider these factors when interpreting the results of a diagnostic test.
