introduction: vertebral arteries arise from the root of the neck as the first branches from the superior-posterior aspect of the subclavian arteries. they ascend the neck to enter the cranial cavity and supply blood to the brain. methods: a total of 20 cadavers (in 10 years) were dissected for the study of variations in the origin of the vertebral artery. this study was conducted in isfahan uni...

Objective: To determine the frequency of various anatomical variations of the cystic duct observed during open cholecystectomy in our set up. Methodology: This study was conducted at department of surgery, Khyber Medical University (KMU), Institute of Medical Sciences (KIMS), Kohat, and a private surgical centre at Kohat, Pakistan. Adult patients of both genders, who underwent open cholecystect...

conclusion our study revealed that the hypoplastic umbilical artery group’s non-dominant cia had higher ri values than the contralateral dominant cia. results eleven of the 165 patients (6.7%) demonstrated a hypoplastic umbilical artery. second-trimester us showed median dominant and non-dominant cia pi values of 1.43 and 1.60 (p = 0.062), respectively, and median dominant and non-dominant cia ...

BACKGROUND AND PURPOSE In some patients with stenosis of an intracranial artery, navigating the balloon or stent-delivery system is difficult of tortuous anatomy of the aortic arch, carotid arteries, or vertebral arteries Our purpose was to describe techniques of intracranial stent placement that help in navigating the stent-delivery system in tortuous vessels. METHODS Between May 1998 and Ju...

Abstract Background Dural sinus malformations (DSM) are rare congenital anomalies, accounting for less than 2% of all intracranial vascular malformations. Fetal MRI plays an important role in the confirmation diagnosis, prognostication, and planning treatment strategies. Here, we present a case dural malformation without thrombosis, diagnosed by prenatal ultrasound fetal MRI. In addition to thi...

The aberrancies concerning the number, origin and course of the testicular arteries are found in an incidence of approximately 4.7-20% in the literature and are documented less frequently than the respective variations of the homonymous veins. In the current study, a very rare complex of testicular arteries' variations isdescribed, in which the occurrence of bilateral double testicular arteries...

Background: The kidneys are supplied by renal arteries which enter the hilum and branch progressively from pyramids to cortex into lobar, interlobar, arcuate, interlobular, finally terminate as afferent arterioles that glomeruli. Thus there is a normal pattern of blood flow towards when artery enters at hilum. aim study was explore glomeruli in with polar arteries.Methods: conducted department ...

BACKGROUND: The aim of this study was to report magnetic resonance imaging (MRI) features of cystic lymphangiomas of the breast. METHODS: MRI of the breast was performed using a phased-array double breast coil with a 1.5-T MR scanner. Routine T1 and T2 and post-contrast sequential imaging was performed. RESULTS: The MRI characteristics of cystic lymphangioma in the breast are described. CONC...

Introduction Arterial cystic degeneration as a cause of symptomatic peripheral vascular disease is uncommon. The most frequently reported site is the popliteal artery, the first description of which was reported in Scandinavia by Ejrup & Hiertonn in 1954, and in Great Britain by Hiertonn, Lindberg & Rob in 1957. Further cases of the disorder affecting the popliteal artery have been reported fre...
