Superior mesenteric artery (SMA) aneurysm is a rare disease. In this case report, we present a 32 years old woman who was admitted to our hospital with chronic abdominal pain. SMA aneurysm was diagnosed after radiological evaluation. The patient underwent ligation of the superior mesenteric artery aneurysm and remained well 12 months after the surgery.

Right hepatic artery (RHA) is a branch of the common artery; however, there are cases documented in literature showing anatomical variations. Accessory RHA an incidental finding during hepatobiliary and pancreatic surgery. This should be identified, carefully separated, preserved these surgeries. We encounter variation while doing Whipple’s procedure 61-year-old patient diagnosed with carcinoma...

Chronic mesenterial ischemia (CMI) is an uncommon cause of abdominal afflictions. The spectrum of therapeutic options ranges from mesenteric artery angioplasty and stenting to surgical revascularization. We used orthogonal polarization spectral (OPS) imaging to assess microcirculation after revascularization of the celiac artery and the superior mesenteric artery. Furthermore, we applicated a p...

This study aimed to examine the expression and function of P2 receptors of the rat tail and mesenteric arteries during maturation and ageing (4, 6 and 12 weeks, 8 and 24 months). Functional studies and receptor expression by immunohistochemistry revealed a heterogeneous phenotype of P2 receptor subtypes depending on artery age. The purinergic component of nerve-mediated responses in the tail ar...

Normal pregnancy is associated with adaptive hemodynamic, hormonal, and vascular changes, and estrogen (E2) may promote vasodilation during pregnancy; however, the specific E2 receptor (ER) subtype, post-ER signaling mechanism, and vascular bed involved are unclear. We tested whether pregnancy-associated vascular adaptations involve changes in the expression/distribution/activity of distinct ER...

Acute mesenteric ischemia is a rare cause of abdominal pain with a very high mortality rate. Vague presentation and often misleading clinical findings make the diagnosis elusive. Here, a unique case of complete superior mesenteric artery occlusion further complicated by basilar artery occlusion is illustrated.

Acute ligation of the common colic and caudal mesenteric artery in the dog led to ischaemic colitis, whereas the acute ligation of the common colic artery and gradual occlusion of the caudal mesenteric artery by an ameroid plastic device did not lead to ischaemic disease. These findings suggest that the collateral blood vessels do not open up rapidly enough to prevent ischaemic change when the ...

The nature of the vasodilator endothelium-derived hyperpolarizing factor (EDHF) is controversial, putatively involving diffusible factors and/or electrotonic spread of hyperpolarization generated in the endothelium via myoendothelial gap junctions (MEGJs). In this study, we investigated the relationship between the existence of MEGJs, endothelial cell (EC) hyperpolarization, and EDHF-attributed...
