in this study we investigated the effects of endothelium removal and l-name on responses to α-adrenoceptor agonists. male wistar rats were killed by overdose with pentobarbitone sodium, after which the left and right common carotid arteries were removed. rings of arteries 3-4 mm in length were cut from each vessel and then mounted in 10 ml isolated organ bath, bathed in krebs maintained at 37°c...

Research into the pattern and variation of brain arteries in wild rabbit involved 43 brains. The main source of blood supply to the brain in rabbit are vertebral arteries and the basilar artery, formed as a result of their anastomosis, as well as internal carotid arteries the branches of which form the arterial circle of the brain. Variation in descent concerns mostly the pattern of descent of ...

Percutaneous transluminal angioplasty was used to treat stenotic lesions in 10 external carotid arteries in nine patients. Four representative cases are described. Nine arteries were successfully dilated. One attempt failed because the catheter could not be passed through the stenosis. Spasm of the distal external carotid artery due to guide wire-catheter manipulation was seen in six patients. ...

Introduction: Arterial stiffness is an important predictor of cardiovascular risk. Several indices have been  introduced to estimate the arterial stiffness based on the changes in the brachial blood pressure. Since the  substitution  of  the  blood  pressure  changes  in  the  central  arteries  such  as  carotid  with  the  blood  pressure  changes in the brachial results in error in the blood...

The purpose of this study was to analyze the suitability of the cerebral vasculature of the pig regarding a revascularization procedure. In two 60 kg pigs the femoral artery was exposed and canulated for selective angiography and interventional procedures. After the angiography, the pigs were brought to the animal OR for craniotomy and analysis of the intracranial cerebral arteries and the surg...

OBJECTIVE To analyze the results of 125 carotid endarterectomies under loco-regional anesthesia, with selective use of shunt and bovine pericardium patch. METHODS One hundred and seventeen patients with stenosis ≥ 70% in the internal carotid artery on duplex-scan + arteriography or magnetic resonance angiography underwent 125 carotid endarterectomies. Intraoperative pharmacological cerebral p...

OBJECTIVES Presence of lymphatics in adventitia of major arteries remains controversial. Presence of lymphatics in adventitia of internal carotid artery was not documented and its relation to atherosclerosis was not studied. The aim of our study was to evaluate presence of lymphatic vessels in adventitia of internal carotid artery in healthy and atherosclerotic arteries. METHODS Fragments of ...

BACKGROUND AND AIMS This study was designed to evaluate the prevalence of calcified carotid artery in 50 year-old and older postmenopausal dental outpatients for early diagnosis of individuals at risk of stroke. MATERIALS AND METHODS This is a descriptive study of 200 panoramic radiographs. These radiographs included post-menopausal women referring to the Department of Oral Medicine at Shahid...

INTRODUCTION Stroke is one of the largest socio medical problems of modern times. In addition to the third leading cause of death, it is the first cause of non-trauma disability. Numerous studies show a correlation of risk factors and arteriosclerotic lesions in the coronary arteries and carotid arteries. PATIENTS AND METHODS Study was conducted at the Clinical Center University of Sarajevo, ...
