Clear awareness of the vascular variations is critical in surgeries, which may cause massive hemorrhage during surgical procedures. During educational dissection a male cadaver, we encountered combined variation left obturator artery and ipsilateral aberrant inferior epigastric artery. The originated from external iliac artery, then coursed inward, adherent to superior pubic ramus. femoral behi...

Arterial variations of distal parts of lower extremities are well-documented and can be demonstrated with the help of Doppler ultrasound or by arteriography. However, absence or variation of posterior tibial artery is considered a rare finding. We present a case of hypoplastic posterior tibial artery that terminated by supplying soleus muscle. The variant arterial supply to the sole was provide...

The vascular anatomy of the liver is subjected to many variations. Aberrant hepatic artery is not an uncommon finding during visceral surgery; however, topographic variations are less reported in the literature. Prebiliary artery crossing anteriorly to the common hepatic duct was firstly reported in 1984. We present here a case of a 52-year-old lady who presented with obstructive jaundice and r...

Introduction Classically, a single renal artery supplies and single renal vein drains each kidney. Variations regarding the origin and number have been reported by many researchers [1–3]. Modern surgical and radiological techniques dictate a reappraisal and definition of the renal vascular anatomy. In this regard, the role of the primary tributaries of the renal vein and their relationship to t...

The anatomical variations in the arterial supply of the palm are frequently reported. One such variation reported during routine dissection for undergraduate medical students in our college is the absence of superficial palmar arch and presence of persistent median artery. The arterial supply to the palm is in the form of superficial and deep palmar arches. In the present case the median artery...

A case is reported of an anomalous origin of the middle colic artery. The middle colic artery originated from the coeliac trunk (CT) instead of the superior mesenteric artery, the normal place of origin. The colon receives its blood supply from the superior and inferior mesenteric arteries. Since modern colon surgery requires a more detailed anatomy of blood supply, many articles have been publ...

BACKGROUND Renal function declines according to age and vascular risk factors, whereas few data are available regarding genetically-mediated effects of anti-hypertensives over renal function. OBJECTIVE To estimate urea and creatinine variations in dementia due to Alzheimer disease (AD) by way of a pharmacogenetic analysis of the anti-hypertensive effects of angiotensin-converting enzyme inhib...

A tissue-like gelatin elasticity-flow phantom was examined to develop ultrasonic strain imaging for the detection of internal pulsatile deformations. The same imaging technique was then applied in vivo to monitor deformation in tissues surrounding the normal brachial artery. The results suggest that vascular strain patterns resulting from biologic stimuli are very different from those generated...

Fundamental gaps still exist in our understanding of cardiovascular disease in women. Women are more likely to suffer from coronary heart disease due to a higher prevalence of very old age relative to men. Women tend to be protected from the development and complications of coronary artery disease (CAD) at younger ages, perhaps due to the beneficial effects of estrogen on the vasculature. A num...
