Acute superior mesenteric vein (SMV) and portal vein (PV) thrombosis can be a complication of hypercoagulable, inflammatory, or infectious states. It can also occur as a complication of medical or surgical intervention. Management of mesenteric and portal vein thrombosis includes both operative and nonoperative approaches. Operative interventions include thrombectomy with ...

Excessive exposure of the fetus to maternally derived corticosteroids has been linked to the development of adult-onset diseases. To determine if early gestation corticosteroid exposure alters subsequent coronary artery reactivity, we administered dexamethasone (0.28 mg.kg(-1).day(-1)) to pregnant ewes at 27-28 days gestation (term being 145 days). Vascular responsiveness was assessed ...

We treated three patients with steroid-refractory acute graft-versus-host disease (aGVHD) with intra-arterial steroid-injection therapy (IAST). Two patients with gut aGVHD received IAST into both superior and inferior mesenteric arteries, while one patient with liver aGVHD received IAST into the proper hepatic artery. The volume of stools and the bilirubin level ...

We performed a total laparoscopic reimplantation of the inferior mesenteric artery (IMA) during laparoscopic infrarenal aortic aneurysm repair. The postoperative course was uneventful, and angiograms showed a patent IMA after reimplantation. To our knowledge, total laparoscopic reimplantation of the IMA in human beings has not previously been described.

1. Experiments were performed to elucidate the mechanism by which alterations of extracellular pH (pH(o)) change membrane potential (E(M)) in rat mesenteric and pulmonary arteries. 2. Changing pH(o) from 7.4 to 6.4 or 8.4 produced a depolarisation or hyperpolarisation, respectively, in mesenteric and pulmonary arteries. Anandamide (10 microm) or bupivacaine ...

BACKGROUND: The hemorrhoidal artery ligation has been used for submucosal ligation of hemorrhoidal arteries by means of an ultrasonographic transducer since 1995. The success of this technique depends on the submucosal course of these arteries. Our investigation deals with branches of the superior rectal artery which pierce the rectal wall ...

Occlusive atherosclerotic disease of the celiac artery may be diagnosed late during pancreatic resection, inducing a sudden ischemic threat to the liver, stomach, pancreas, and new anastomoses. Failure to identify and correct the insufficient supramesocolic flow can result in serious morbidity. We report the case of a 64-year-old man in ...

We report a new strategy--celiac artery stenting--to relieve stenosis of the celiac arterial root. This was performed in two patients with pancreaticoduodenal artery (PDA) aneurysm associated with a stenotic celiac arterial root. The first patient was a 66-year-old man complaining of abrupt onset of upper abdominal pain. Abdominal computed tomography ...

Two patients with superior mesenteric artery embolism are presented. In both cases, contrast-enhanced computed tomography (CT) demonstrated enhancement of the superior mesenteric artery roots and non-enhanced filling defect in the more distal part of the artery. Immediate extraction of the embolus saved 1 patient but massive bowel resection was necessary ...

Portal and mesenteric venous thrombosis is an uncommon condition that is usually treated with systemic anticoagulation. Catheter-directed thrombolysis via the superior mesenteric artery may be a viable adjunct to treatment of this potentially morbid condition. We present a case of portal and mesenteric venous thrombosis treated with systemic anticoagulation and ...

Isolated dissection of superior mesenteric artery is a rare condition and is usually treated surgically. We treated a patient with severe abdominal pain who was angiographically confirmed to have superior mesenteric artery thrombosis associated with isolated spontaneous dissection. He was treated initially by thrombolysis and oral anticoagulation, but recurrent symptoms ...

We report on a female patient with hereditary hemorrhagic teleangiectasia complicated by subacute thrombosis of the superior mesenteric vein. Despite gastrointestinal bleeding, anticoagulation therapy with heparin had to be performed to prevent bowel infarction. In this case, local vascular lesions with altered blood flow in combination with hyperfibrinogenemia might have ...

We tested the hypothesis that the differential sensitivity of rabbit aorta and mesenteric artery to norepinephrine is due to tyrosine kinase activity. The EC50 of aorta to norepinephrine was 6.5 times more sensitive than that in mesenteric artery. Basal myosin light chain phosphorylation was significantly greater in aorta as compared ...

As the popularity of juxta-acetabular osteotomies in adults increases, concern arises that such a procedure will potentially cause avascular necrosis of the acetabular fragment. In order to verify the remaining vascularization after a Bernese periacetabular osteotomy, an injection study with colored latex was performed. The vascularity of the outside of ...
