Aneurysmal subarachnoid haemorrhage which has a serious mortality and morbitity ratio, occurs approximately 10/100.000 population per year and it is usally caused by rupture of a cerebral artery aneurysm. Aneurysms are classified saccular, fusiform or dissecan by morphological description. Vascular congenital anomalies of the cerebral vessels contribute to saccular aneurysm formation by increas...

Living donor liver transplantation has been associated with severe vascular complications like hepatic artery thrombosis, which commonly involves the hepatic segment 4. Most authors have defined the artery to this segment as the middle hepatic artery. The present study was undertaken to characterize the origin of middle hepatic artery and classify the variations observed in cadaveric livers, an...

The selective accumulation of different leucocyte populations during inflammation is regulated by adhesion molecules and chemokines expressed by vascular endothelium. This study examined how chemokine production and the expression of adhesion molecules and chemokine receptors vary between endothelia from different vascular beds. Human saphenous vein endothelium was compared with lung and dermal...

Variations in the arterial pattern of the upper limb are very common as observed in many cadaveric and angiographic studies. Knowledge of variations in the origin and course of the radial artery is important because they are used for many diagnostic procedures as well as vascular and reconstructive surgeries like coronary angiography, percutaneous coronary intervention and coronary artery bypas...

INTRODUCTION: Variations in anterolateral thigh (ALT) arterial anatomy are well documented. Ethnicity is a known risk factor for vascular variation in several organ systems, but its impact on ALT anatomy has not been studied. Anecdotally, we observed frequent ALT arterial variation in African American (AA) patients. We thus hypothesized that AA patients have higher rates of anomalous branching.

Congenital absence of the left portal vein is a rare vascular anomaly with a reported prevalence varying from one in 62 to one in 507 cases. A patient admitted for recurrent cholangitis secondary to extensive dilation of the left biliary ductal system associated with Caroli's Disease was determined by preoperative dynamic CT to have an excessively large right portal vein and no left portal vein...

Understanding anatomy of the vascular variations of kidney is essential for the clinician to perform procedures such as renal transplantation, interventional radiological procedures and renal vascular operations more safely and efficiently. In order to facilitate the clinical approaches, we studied renal arterial pattern in 50 formalin-fixed cadavers, on 100 kidneys. We observed prehilar multip...

Vascular responses in the large central pad of the dog's foot were recorded during stimulation of the lumbosacral sympathetic trunk and correlated with the site of stimulation and the subsequent histologic analysis of the excised trunk. The resulting description of the preganglionic inflow and postgaiiglionic outflow from the trunk demonstrated marked variations in the anatomic patterns of the ...

to study the seasonal variation in the characteristics of the azarbaijani buffalo semen, three 2-4-year-oldbulls of azarbaijani water buffaloes, kept in the buffalo breeding center, in urmia, northwest of iran, wereselected. semen samples were collected once a week for a period of one year using artificial vagina and abuffalo cow as a dummy. semen volume, colour, ph and motility and spermatozoa...
