Unilateral and bilateral variation in the course and elongation of the cervical (extracranial) part of the internal carotid artery (ICA) leading to its tortuosity, kinking and coiling or looping is not a rare condition, which could be caused by both embryological and acquired factors. Patients with such variations may be asymptomatic in some cases; in others, they can develop cerebrovascular sy...

BACKGROUND Vascular variations regarding the branching pattern of the aorta are important in different laparoscopic surgeries, liver and kidney transplantation, oncologic resections, and various interventional radiological procedures in the abdominal region. The present work was undertaken on cadavers to examine the prevalence of vascular patterns of the important branches of the abdominal aort...

The variations of vessels arising from the aortic arch are numerous. The purpose of this study is the description of the variations on the branching pattern of arch of aorta, in order to offer useful data to anatomists, radiologists, vascular surgeons, neck and thorax surgeons in Nepalese subjects, and relating it with embryological basis. In this investigation, branching patterns of arch of ao...

INTRODUCTION Vascular patterns are important in the planning and performance of all upper abdominal surgical procedures. The coeliac trunk arises from the abdominal aorta and supplies the supracolic organs. Knowledge of variations of the coeliac trunk is important in procedures such as liver transplants for appropriate vascular ligation and anastomosis. METHODS The branching patterns of the c...

The anatomy of axillary neurovascular architechture is very important for neurosurgeon, plastic and cardiovascular surgeons, and also radiologists to aid in diagnosis, treatment and planning surgical procedure. Walsh and Willar were firstly described brachial plexus (BP) anatomy in details from 1877 (Akboru et al, 2010). After rapid development of microsurgical approaches, variations and injuri...

BACKGROUND AND OBJECTIVES The circle of Willis, an anastomotic polygon at the base of the brain, forms an important collateral network to maintain cerebral blood perfusion. The aim of this study was to investigate different anatomic variations of the circle of Willis and their prevalence. METHODS This cross-sectional study was conducted on 525 healthy participants including 205 men and 320 wo...

Background and Aims: The purpose of this study was to demonstrate the hepatic vascular anatomy and the variations in living right lobe donors by multidetector computed tomography angiography before the transplantation surgery and to detect the prevalence of these variations. Materials and Methods: Fifty-one potential liver donors (20 females, 31 males) underwent hepatic vascular computed tomogr...

Anatomic tissue atlases of the brain are widely used within the medical world and are important for identifying tissue and structural aberrations and inconsistencies within an individual. Unfortunately, there are many procedures and diseases that require examination of the brain’s vascular system, which is not easily identifiable in anatomic atlases. We present a new concept of a brain vascular...

PURPOSE The statistical power of functional MRI (fMRI) group studies is significantly hampered by high intersubject spatial and magnitude variance. We recently presented a vascular autocalibration method (VasA) to account for vascularization differences between subjects and hence improve the sensitivity in group studies. Here, we validate the novel calibration method by means of direct comparis...
