The control of force production in vascular smooth muscle is critical to the normal regulation of blood flow and pressure, and altered regulation is common to diseases such as hypertension, heart failure, and ischemia. A great deal has been learned about imbalances in vasoconstrictor and vasodilator signals, e.g., angiotensin, endothelin, norepinephrine, and nitric oxide, that regulate vascular...

PURPOSE To present the CT characteristics of histologically confirmed venous vascular malformations limited to the submandibular triangle in patients without clinical stigmata of venous vascular malformations. METHODS The clinical records and CT scans of five women with venous vascular malformations limited to the submandibular triangle were reviewed. Patients ranged from 39 to 70 years of ag...

Guidelines on managing infants after initial anti-vascular endothelial growth factor (VEGF) treatment (eg, bevacizumab) for retinopathy of prematurity (ROP) are limited. We found that following bevacizumab ROP, prophylactically lasering infant eyes before hospital discharge reduced the number and duration outpatient ROP screening examinations compared with infants, per current United States (US...

Aneurysms and pseudoaneurysm are commonly encountered with arteriovenous vascular access for haemodialysis. They difficult complications to manage. Due the limited number of centers available, patients were unable seek treatment until further arise. The technique partial aneurysmectomy primary repair was adopted as method in this study. A total 20 cases underwent surgery from 2019 2020. Among c...

multiple sclerosis (ms) is a chronic auto-immune disease. most therapeutic strategies for treatment of this disease direct immune modulation and control of inflammatory processes. first-line therapeutic agents showed moderate efficacy and frequent side-effects with moderate efficacy in trials. their parental administration and limited long-term adherence restrict their efficacy compared with se...

statins are most effective pharmacologically agents to decrease total plasma cholesterol level by competitive inhibition of hmg-co a reductase. apart from the well-known ldl and cholesterol lowering effect, statins have been postulated to exert other beneficial effects also called pleotropic or non-lipid effects. better understanding of various pleotropic effects of statins has prompted a new s...

congenital anomalies of the great thoracic vessels have been reported in 20% of dogs and cats. in some cases, the vascular ring anomalies remain unrecognized throughout the lifetime of an animal. this report describes a case with an unusual vascular ring anomaly (vra) that was detected during dissection on a cadaver of an approximately two-year-old male native mixed breed dog. no history of the...

case presentation we reported a 2-year-old boy with pph, who presented unusual and intractable seizure which suggested the diagnosis of md. we also reviewed a few previous reports about the association of pph with moyamoya disease. discussion moyamoya disease is a kind of cerebral vasculopathy and should be considered as a differential diagnosis for patients with unusual seizure attacks who are...

Modern high-technology methods for ischemic stroke treatment (systemic thrombolysis, mechanical thrombectomy, thrombaspiration, stenting of cerebral arteries) can improve the rehabilitation potential and survival patients. Important tasks here are selection reperfusion its performance on greatest possible number peracute Mechanical thrombectomy combined with systemic thrombolysis is most effect...
