Pseudoaneurysm is defined as blood leaking out of a vessel that does not have true 3 arterial walls like a true aneurysm, and is susceptible to rupture. Only 4 patients of pseudoaneurysm after endoscopic sinus surgery have been reported so far in English literature. Recently, the authors encountered a pseudoaneurysm in the internal maxillary artery after endoscopic sinus surgery, which was imme...

Leiomyosarcoma (LMS) is a rare malignant tumor of smooth muscle origin that generally stems from soft tissues and uterine tissue. Although, a small percentage of these may originate from the smooth muscle or vessel walls, most of which are of venous origin. Renal leiomyosarcomas may arise from the smooth muscle fibers of renal pelvis, renal capsule or renal vessels, last one is the most frequen...

A case of eosinophilic fasciitis is presented. The clinical, biochemical and pathological findings were similar to those described in the literature. The history of violent exercise present in most patients was absent in our case. Immunofluorescent studies of the fascial and muscular biopsy showed deposits of C3 and fibrinogen in the vessel walls. The information of E rosettes by T lymphocytes ...

A 14-year-old girl presented with a 2-week history of progressive facial ulcerations that did not respond to cephalexin and topical dexamethasone. Biopsy on the ulcer showed rod-shaped bacteria and actinomycetes-like mycelia in the vessel walls and within thrombi. Tissue culture yielded Acinetobacter baumannii, which was resistant to cephalexin. A favourite outcome was achieved with minocycline...

Blood pressure is the force of blood pushing against blood vessel walls as the heart pumps out blood, and high blood pressure, also called hypertension, is an increase in the amount of force that blood places on blood vessels as it moves through the body. Factors that can increase this force include higher blood volume due to extra fluid in the blood and blood vessels that are narrow, stiff, or...

Platelet aggregation responses to 5-hydroxytryptamine (5-HT) were measured in plasma from migrainous subjects taking either methysergide maleate or ergotamine tartrate and were found to be reduced. Blood 5-HT levels of subjects free of headache were not affected by these drugs. The results support the hypothesis that methysergide and ergotamine act by occupying 5-HT uptake sites in vessel walls...

We study experimentally the influence of confinement on the penetration depth of impacting spheres into a granular medium contained in a finite cylindrical vessel. The presence of close lateral walls reduces the penetration depth, and the characteristic distance for these lateral wall effects is found to be of the order of one sphere diameter. The influence of the bottom wall is found to have a...

Non-alcoholic fatty liver disease, which is considered a hepatic manifestation of metabolic syndrome, independently increases the risks of developing cardiovascular disease (CVD) and type 2 diabetes mellitus. Recent emerging evidence suggests that a group of predominantly liver-derived proteins called hepatokines directly affect the progression of atherosclerosis by modulating endothelial dysfu...

Introduction 2D cross-sectional Dual-Inversion-Recovery (DIR) blackblood imaging of the coronary arteries has been used to assess Kawasaki Disease (KD) (Greil et al. 2007). A 3D coronary black-blood approach, however, has been shown to provide better coverage of the coronary tree (Botnar et al 2001). Furthermore, uptake of gadolinium contrast agent in coronary walls may indicate on-going inflam...

Systemic vasculitis is a group of heterogeneous diseases characterized by inflammation and blood vessel walls necrosis. Usually the skin is one of the first organs involved, especially with damage of small to medium size vessels. The cutaneous patterns may help clinicians to diagnose these diseases at the beginning of their course, preventing complications due to internal organ involvement. ...
