PRIMARY HYPOTHESIS:. Compared with intensive medical therapy alone, intracranial angioplasty and stenting combined with intensive medical therapy will decrease the risk of the primary endpoint by 35% over a mean follow-up of two years in high-risk patients patients with 70% - 99% intracranial stenosis who had a transient ischemic attack (TIA) or stroke within 30 days prior to enrollment) with symptomatic stenosis of a major intracranial artery.. SUMMARY:. The best treatment for prevention of another stroke or TIA in patients with narrowing of one of the arteries in the brain is uncertain. A common treatment is the use of anti-clotting medications to prevent blood clots from forming in the narrowed vessel. There are a variety of medicines used for this purpose. These medications are usually taken for the rest of a patients life.. However, a treatment that has been used successfully together with anti-clotting medications in patients with narrowing of the blood vessels of the heart is now being ...

The management of biliary strictures depends on their correct pre-operative evaluation which remains challenging. Biliary strictures have various etiologies (traumatic, inflammatory, tumoral, ischemic etc), which are necessarily needed to be known for the correct therapeutic approach. Despite the emerging multitudes of new diagnostic opportunities and modalities (laboratory, radiological, endoscopic, histopathologic and immunohistological) which exist today, there is still a large number of biliary stenosis misdiagnosed with a profound negative impact on the patients´ outcome. The dilemma that exists is how to balance the risk of missing the chance of curative surgery for some malignancy and preventing some patients from unnecessary surgery for benign etiologies and not to waste time. Therefore, diagnostic methods which can maximize the chance of the preoperative diagnosis of indeterminate biliary strictures are needed.. This study will:. compare two methods helping in the diagnosis of ...

We performed this clinical trial to evaluate the outcome of symptomatic IAS and to evaluate the efficacy of cilostazol in this condition. The major findings of our study are: (1) the symptomatic IAS is a dynamic lesion; and (2) aspirin plus cilostazol regimen is tolerable and superior to aspirin monotherapy in the prevention of the progression of symptomatic IAS.. Because digital subtraction angiography was considered invasive, we used MRA to assess the IAS in this study. To augment the reliability of the results, we additionally used TCD. Because there are no validated criteria for the change of IAS with TCD, we arbitrarily defined the change of ,20 cm/s and 20% of mean flow velocity as a significant finding. The results obtained by MRA and TCD were similar and concordant. On MRA study, the symptomatic IAS progressed in 29% and regressed in 15% in patients receiving aspirin alone, illustrating that symptomatic IAS is subject to change even at 6 months of follow-up. This dynamic change of ...

Benign biliary strictures are a common clinical entity encountered by the interventionalist. Balloon dilatation is an acceptable modality of treatment, but restenosis is frequent. The recoil that follows balloon dilatation of recalcitrant benign biliary strictures presents a treatment challenge. This chapter presents a single-access dual-drainage catheter technique that has been employed successfully for more than 6 years. The procedure involves the standard placement of a large drainage catheter (ideally 14 Fr) across the biliary stricture. A second catheter measuring between 5 and 8.5 Fr is advanced through the hub of the 14 Fr drainage catheter and subsequently exits through a proximal hole of the 14 Fr drainage catheter. At the site of the stricture, there is side-by-side placement of the two drainage catheters providing extra scaffolding despite the 14 Fr percutaneous tract.
Allograft vasculopathy is an accelerated intimal hyperplastic lesion leading to progressive vascular stenosis; it represents the major long-term limitation to successful solid organ transplant. Although allograft vasculopathy is not formally an autoimmune disease, nor does it constitute a major cause of cardiovascular disease on a purely numerical basis, its pathogenesis provides an important window on the mechanisms by which immune injury can drive more common vascular pathologic entities. Thus, insights gleaned from vascularized solid organ transplants can shed new mechanistic (and therapeutic) light on: 1) the intimal vascular responses accompanying typical atherosclerosis and other inflammatory vessel diseases (e.g., scleroderma); 2) the pathogenesis of vascular stenosis versus aneurysm formation; 3) the sources of intimal smooth muscle cells in the healing of any vascular injury; and 4) the mechanisms by which smooth muscle cells are recruited into intimal lesions. Indeed, research on allograft

Arterial stenoses and luminal-surface irregularities at anastomoses cause blood-flow disturbances with slow recirculation. The authors created a computer simulation to study the rates of the release into blood of atherogenic substances such as low-density lipoproteins and their breakdown products from within the arterial walls at stenoses. Finite-difference methods were used to solve the Navier-Stokes equations (in the form of stream function and vorticity function) and the steady-state mass transfer equation for bell-shaped stenoses with two different degrees of constriction. This simulation indicated that the efflux rates of lipids and their breakdown products from the vessel walls were suppressed in the region of disturbed flow, with slow circulation distal to stenoses. The lowest efflux rate was found at the point of flow separation, and this rate was much lower than rates in regions of undisturbed flow. Therefore, this mathematical model predicts that locally disturbed blood flow at arterial

There is wide disagreement among studies that have evaluated the accuracy of urea recirculation (UR) in detecting vascular access stenosis. The 3-site method (UR3) has been discredited and replaced by the 2-site method (UR2), but few studies have evaluated UR2. Methods. We compared the accuracies of UR2 and UR3 in detecting stenosis in 59 haemodialysis patients during a 12-month period. All patients were studied without regard to clinical suspicion of stenosis. Stenosis (≤ 50% luminal narrowing) was diagnosed by duplex ultrasound and confirmed by angiography. The reproducibility of UR2 was determined by computing its total standard ...
We hypothesize the reason the vessel distal to the stenosis appeared occluded on DSA images, when CTA clearly showed the vessel to be patent, is related to differences in image acquisition time for DSA and CTA modalities. Angiographic runs are obtained during the course of a single intracranial circulation cycle, typically 5-7 seconds on average, by using a 3-4 frame per second filming rate, whereas CTA studies are acquired over approximately 60 seconds by using a single detector and 30 seconds by using a four detector helical scanner, allowing the contrast material to circulate up to 4-12 times in the intracranial vessels before imaging, which permits flow of a larger volume of contrast material through a tight stenosis. This greater volume of contrast material distal to a tight stenosis coupled with the HU-based methods of transmission tomography, may help to make these vessel segments more conspicuous, thus rendering visibly stenotic, but patent, arterial segments on CTA images that appear ...

Results Thirty stents were deployed. Before stenting, the mean vessel diameter was 3.4±0.21 mm at point A, 3.06±0.18 mm at B, 3.16 ± 0.21 mm at C, 2.67 ± 0.27 mm at D, and 2.56 ± 0.23 mm at E. The deployment of two stents resulted in statistically significant increases in both the average vascular diameter and cross sectional area (CSA) at points C (3.51±0.22 mm and 9.76±1.17 mm2, P= 0.0006 for diameter and 0.001 for CSA, respectively) and E (2.88±0.32 mm and 7.28±1.46 mm2, P= 0.01 for diameter and 0.02 for CSA, respectively) compared with pre-stenting. At angiographic follow-ups compared with before stenting, significant increases were documented at point C (3.42±0.22 mm and 9.42±1.37 mm2, respectively) at first angiographic follow-up but at points A (3.62±0.45 mm and 10.51±2.37 mm2) and B (3.26±0.24 mm and 8.47±1.26 mm2) at second angiographic follow-up. No significant vascular stenosis was demonstrated at double stent segment compared with single stent or native artery segments. ...
Pulmonary fibrosis is a scarring of the lungs. We have few treatments and none to reverse it. Bronchiectasis is a chronic scarring infection of lung with grape-like collections of pus-filled cavities adjacent to airway passages in the lung. They cause a chronic cough and serve as reservoirs of chronic infections. Bronchiectasis is treated medically and surgically in select patients. COPD stands for Chronic Obstructive Lung Disease, and usually requires aggressive medical management (multiple inhaler and oral medications) to reduce recurrent infections, lung and heart failure, and hospitalization. It sounds like you need to optimize your existing lung function, and stop smoking now if you still smoke. If you have been a non-smoker, more investigation is usually needed ...

Elasticity is known as the spatial rate of change of displacement as a result of the tensile stress created by a certain amount of pressure on live tissue. A displacement in tissues can be created by external compression or internal physiologic forces, such as vascular pulsation.2,3 On the external compression method, strain evaluation by elastography in sonographic devices equipped with software is performed by periodic and short-term up and down movements of the probe on the tissue. During downward compression, slight pressure is applied. The strain level of the tissues can be observed in real-time in different color codes. In the systems involving the combined autocorrelation method developed by Shiina et al,12 which we also used in our study, there is a pressure scale simultaneously displaying the appropriateness of the manipulation as upward and downward movements on the sonography screen. The application is correct when the values displayed on the scale are 3 and 4 (Figs 1⇑⇑⇑-5). ...

In the literature, one finds few obvious associations with other hereditary or acquired diseases distribution of fats.. 1) The syndrome of DERCUM. Exceptionally, the pelvic lipoma could be integrated in a syndrome of DERCUM (4 cases). It is about an affection characterized by the presence of painful fat masses laid out on the trunk and the members, by obesity, sensitive and psychic disorders; the evolution is fatal and of unknown origin. Sometimes, hormonal disorders are discovered (thyroid and pituitary gland).. 2) Lubricating degeneration of lymphatic (hypoplastic pelvic lymphadenopathy). It is about a very rare affection (2 cases in 1975 less than 10 cases in 1983). The lymphatic ganglia are invaded gradually by mature fatty tissue, without any sign of malignity.. On the level of the small basin, the ganglia are bulky and at the origin of an extrinsic compression of the pelvic bodies.

REPORTING FROM ISC 2018. LOS ANGELES (FRONTLINE MEDICAL NEWS) - A postmarketing study of the Wingspan stent shows that the safety of the device in the treatment of intracranial atherosclerotic disease (ICAD) is good enough to be a reasonable alternative to medical management in these patients, but only if the device is used on label.. The results may reassure some interventionalists who were alarmed by results from the Stenting versus Aggressive Medical Management for Preventing Recurrent Stroke in Intracranial Stenosis (SAMMPRIS) trial ( N Engl J Med. 2011;365:993-1003 ), which showed a 30-day rate of stroke or death of 14.7%. The new study showed a frequency of 2.6%, so long as the device was used on label. Off-label use yielded a frequency of 23.9%.. It does suggest that there may be a reevaluation of stenting as a treatment for symptomatic ICAD, particularly in patients who have failed medical therapy, based on the safety profile were seeing now, Michael Alexander, MD , said during a ...

Ruchir Puri, MD, Steven P Bowers, MD. Mayo Clinic, Florida.. The video submission is a case presentation of a 66 Y male who underwent a TIF (transoral incisionless fundoplication) complicated by mediastinitis. He developed severe, refractory dysphagia. He was found to have extensive fibrosis and thickening of the esophageal wall with extrinsic compression of the esophageal mucosa. Because of the finding of normal esophageal mucosa, the authors felt esophageal preservation was reasonable. After failing over thirty endoscopic dilatations and requiring parenteral nutritional support he consented to the operation. The video demonstrates mediastinal dissection in the setting of severe periesophageal fibrosis, at times limited visibility due to steam production and subsequent myotomy of the thickened fibrotic anterior esophageal wall. An omental patch was used to buttress the myotomy and separate the fibrotic edges. Intraoperative endoscopy was performed to ensure an adequate myotomy and a ...

It is well recognised that vascular tissue and mechanisms of cervical arterial dysfunction (CAD) may give rise to pain in the cranio-cervical region (Taylor and Kerry 2005). It is perhaps less well known that vascular tissue can be the source of pain syndromes throughout the body, ranging from the obvious - abdominal aortic aneurysm (low back pain), through to the less obvious (or less well known) distal limb pain/numbness as a result of popliteal artery entrapment syndrome (PAES). PAIN may be local due to a nociceptor response in the tunica adventitia due to underlying pathology (arterial dissection, atherosclerosis, aneurysm) or distal due to ischaemia (which may be movement or exercise induced ...

Intestinal strictures are a common complication of Crohns disease. Strictures are a narrowing of a specific section of your intestine that makes it difficult for food to pass through. They may sometimes lead to intestinal blockage.. Strictureplasty is a type of surgery used to correct strictures in your digestive tract. In this article, well take a look at the procedure, risks, and recovery. Strictureplasty is a surgical treatment for intestinal strictures. It involves widening damaged parts of your intestines. If multiple strictures are present, they can be treated at the same time.. The authors of a 2007 meta-analysis of 3,529 strictureplasties concluded that strictureplasty is a safe and effective treatment for strictures in the lower part of your small intestine, including the ileum and the jejunum. Strictures caused by Crohns disease typically occur here.. Strictureplasty is less effective at treating strictures in the upper part of your small intestine or duodenum, which are more likely to ...
The Stenting versus Aggressive Medical Management for Preventing Recurrent Stroke in Intracranial Stenosis (SAMMPRIS) study, is the first stroke prevention trial to compare intracranial stenting with medical therapy and incorporate intensive medical management to the study design. Patients in the study were ages 30 to 80 years old and had experienced a recent transient ischemic attack or another type of non-disabling stroke. All patients participated in a lifestyle modification program focused on quitting smoking, increasing exercise, and controlling diabetes and cholesterol ...

Results We included 312 patients (mean age, 59.0 ± 14.2 years; men, 58.3%), of whom 113 had ICAD and 199 had ICAS. The functional outcome (as measured by modified Rankin Scale score) on the 90th day after symptom onset was not different between the groups, after adjusted for other factors (p = 0.095). However, recurrent ischemic cerebrovascular disease on the relevant vascular territory was lower in the ICAD group (7 patients, 6.2%) than in the ICAS group (37 patients, 18.6%). ICAD was a significant independent determinant of disease recurrence (hazard ratio, 0.43; 95% confidence interval, 0.19-0.98). Improvement in vascular stenosis on follow-up vascular studies was more frequently observed in ICAD (50.7%) than in ICAS (11.6%). ICAD was an independent determinant of vascular improvement (odds ratio, 7.94; 95% confidence interval, 3.32-19.01). ...
Trial to provide first clinical experience in fistula surveillance for early detection and prediction of fistula stenosis. OR YEHUDA, ISRAEL - February 16, 2021 - PatenSee, developer of a contact-free surveillance tool designed to identify asymptomatic stenosis, today announced the initiation of its first in-human clinical trial for its machine vision-based surveillance system. The trial, led by Prof. Benaya Rozen-zvi, director of the Institute for Nephrology and Hypertension at Rabin Medical Center, will evaluate the systems ability to perform contact-free surveillance of fistula stenosis similar to a nurses physical exam of hemodialysis patients.. The clinical data we collect will be the first of its kind and will provide a critical step towards a reliable contact-free early detection tool for fistula stenosis, explained Prof. Benaya Rozen-zvi. Keeping the fistula open is a major clinical need, and early detection of stenosis allows for both simpler treatment and better prognosis for the ...
association with CVA in dogs.4 With brain hematomas, seizures, dementia and comas are common signs. They derive from remnants of the notochord (rod like structure in embryos from which the spinal column develops). Intracranial Disease Management Basics : Bob Stein : December, 2004 : 1) RECOMMENDATIONS a) General Approach i) Avoid any increase in intracranial pressure. Extracranial (upper portion of the skull that protects the brain) metastases of primary brain meningiomas have been reported. It differentiates to form the nervous system and the epidermis). b. Oligodendrocytomas are seen frequently in brachycephalic breeds. The midline location in the brain is not explained clearly. Future breakthroughs comprise transient osmotic blood brain barrier disruption or transient opening of the blood brain barrier with the help of bradykinin analogs (drug that helps to dilate blood vessels and reduce blood pressure). If your dog is experiencing seizures you should take them to the vet immediately. The ...

The left atrium and pulmonary veins initially develop separately in the 3- to 5-mm embryo (25 to 27 days gestation).1 The primordial pulmonary venous system is part of the splanchnic plexus, which initially connects to the cardinal and umbilicovitelline veins. At 27 to 29 days gestation, a small endothelial outgrowth from the posterior superior wall of the primordial left atrium develops just to the left of the developing septum primum. At 28 to 30 days gestation, this common pulmonary venous out-pouching engages the pulmonary venous portion of the splanchnic plexus and begins to drain blood from the pulmonary system. In normal development, the connections to the cardinal and umbilicovitelline systems atrophy, which results in complete separation between the pulmonary and systemic venous systems.. The sequence of connection of the out-pouching of the left atrium to the pulmonary venous plexus, followed by incorporation of the confluence of the common pulmonary venous system into the left atrium, ...

Our prospective study demonstrates that LE-PAD patients with a hypoechoic plaque in the femoral arteries are exposed to a significantly higher risk of developing myocardial infarction or stroke compared with those with a hyperechoic femoral plaque. Similar findings were obtained with both computer-assisted and visual analyses of plaque echogenicity. Notably, these results remained unaltered after accounting for factors known to have important impacts on LE-PAD patients outcome, including age, sex, previous cardiovascular events, and ABI.. Acute ischemic events are more closely related to the histopathological characteristics of atherosclerotic plaques than to the number of plaques or the degree of vascular stenosis (2,5-8,28,29). In this regard, the PROSPECT (Providing Regional Observations to Study Predictors of Events in the Coronary Tree) trial (8) has recently shown that lesions responsible for recurrent cardiac ischemic events are frequently angiographically mild, most are thin-cap ...
Preoperative evaluation. I. Circulatory status - evaluation of cardiac function. 1. Does the history of angina result in unusual risk to anesthesia and this surgery? Explain.. 2. Is additional workup needed?. 3. What tests do you want? Explain.. 4. How would you manage his preoperative cardiovascular drugs? Explain your rationale.. 5. How do nitrates cause antianginal effects?. Beneficial antianginal effects are a result of platelet effects, reducing myocardial demand, and increasing coronary perfusion. Nitric oxide inhibits platelet aggregation, venodilation decreases venous return and thus decreases left ventricular filling pressures, wall tension, and myocardial oxygen demand. Coronary spasm is relieved, and epicardial coronaries, collaterals, and stenotic segments dilate.. II. Assessment of cerebral blood flow. 1. What is the significance of transient ischemic attacks?. 2. Discuss cerebral vs cardiac etiologies.. 3. How will you assess this patient preoperatively?. 4. What significant ...
A 55 y/o woman was admitted to our hospital to be considered for the second renal transplant. She had agenesis of the left kidney and several stenotic segments in the right ureter which were associated with repeated pyenonephritides during her childhood. Ureteroplastic operation and partial resection of the right kidney were performed when she was 15 year old. Her renal function slowly deteriorated and at the age of 35 she started haemodialysis. A year later she received a cadaveric kidney and that graft functioned for 18 years. She underwent graftectomia and after one year on dialysis she received the second cadaveric kidney. The surgery was followed by delayed graft function, and a renal biopsy was performed on the day 6. C4d was negative and acute T-cell mediated rejection (ATCMR) grade IIA was diagnosed. She was treated with solumedrol. Her renal function slowly improved and the serum creatinine level (S-Cr) stabilized on 170μmol/l (1.9mg/dl). She felt well and came to the hospital 3 months ...
There is an extrinsic compression of the proximal portion of the left brachiocephalic vein between the innominate artery and medial end of the right clavicle.
External compression headaches can occur when something worn on your head puts continuous pressure on your forehead or scalp. They often occur in people required to wear certain headwear, such as helmets or goggles, for their work or sports activities.. Sometimes an external compression headache is called swim-goggle headache or football-helmet headache or another name that refers to the equipment causing the headache. ...
