Isolated dissection of visceral arteries without associated aortic pathology is very rare. Risk factors, etiology, and natural history of this pathology continue to be unclear, and the guidelines for clinical management remain to be defined. We present a case not described previously, with sequential dissections of the celiac trunk, superior mesenteric artery, and renal arteries without aortic involvement. The patient presented with severe back thoracic and abdominal pain and without evidence of peritonitis...

Superior mesenteric artery (SMA) aneurysms are rare but associated with significant mortality (25-40%) when complicated by rupture or thrombosis. Symptomatic SMA aneurysms, asymptomatic aneurysms of ≥2 cm size and pseudoaneurysms need intervention. We report a case of a 6.5-cm symptomatic SMA aneurysm managed by open surgical repair. At intraoperative exploration, the aneurysm was recognized to be a pseudoaneurysm with a narrow neck (1 mm defect in the native vessel) and was dealt by primary repair. Clinical presentation, the role of radiological investigations and management are discussed...

Superior mesenteric artery (SMA) aneurysms represent a minority of visceral aneurysms but may result in lethal complications if left untreated. Options for treatment include aneurysmorraphy, bypass, ligation, or embolization. Here we present a case of a man with a history of celiac graft thrombosis who presents with a recurrent symptomatic SMA aneurysm. Given his compromised celiac axis, ligation was not an option. His SMA aneurysm was repaired with a PTFE patch. However, to secure longstanding blood flow to the small bowel in the event of graft thrombosis, the distal SMA pedicle was dissected free of the ileocolic vessels and anastomosed to the aorta...

PURPOSE: Our objectives were to clarify the management of isolated spontaneous dissection of the superior mesenteric artery (DSMA). METHODS: We reviewed seven patients diagnosed as having DSMA from 2002 to 2007 (group A). Simultaneously, we analyzed 50 cases of DSMA previously reported in the literature between 2000 and 2008 (group B). In each group, clinical presentation, Sakamoto's classification, imaging appearances, need for emergent surgery, failure of medical management, and long-term outcome were analyzed...

BACKGROUND: Spontaneous isolated dissection of the superior mesenteric artery (SMA) is uncommon. Because of its rarity, the risk factors, aetiology and natural history are unclear, and there is no consensus on the optimal treatment strategy. METHODS: Seven consecutive patients with symptomatic spontaneous isolated SMA dissection who received conservative treatment between March 2003 and February 2008 were included in this study. Their clinical characteristics, treatment methods and outcomes were analysed retrospectively...

Descending thoracic and abdominal aortic coarctations are characterized by a segmental narrowing that frequently involves the origin of the visceral and renal arteries. Optimal primary treatment is debated, being reported for both surgical and percutaneous complications. We describe our surgical experience with two youths presenting with failure of distal descending aortic stenting and with abdominal aortic coarctation post-balloon angioplasty, and associated thrombosis of a stented right renal artery and stenosis of the origin of the superior mesenteric artery (SMA)...

Superior mesenteric artery (SMA) injury is a rare event during abdominal surgery. We report the first case of inadvertent injury of the superior mesenteric artery during surgery of a large malignant adrenocortical tumor with inferior vena cava thrombus. The cause of inadvertent injury was anatomical distortion of the great vessels due to the massive nature of the tumor. The case was managed successfully by immediate end-to-end anastomosis of the superior mesenteric artery.

Aneurysms of the pancreaticoduodenal arteries (PDA) are rare, accounting for <2% of all visceral aneurysms. An association with celiac artery stenosis has been reported. Many present with rupture, and a high mortality can be expected. Treatment is therefore challenging. Arterial ligation, anuerysmectomy, or bypass has been the mainstay of treatment. We recently treated a patient (who had no celiac axis) with a ruptured PDA aneurysm with combined open and endovascular techniques. A 46-year-old man was transferred to our hospital with a 1-day history of abdominal pain and syncope...

OBJECTIVE: To study findings at autopsy in patients with fatal acute thromboembolic occlusion of the superior mesenteric artery (SMA). SUMMARY BACKGROUND DATA: Acute occlusion of the SMA is difficult to diagnose and mortality remains high. In Malmo, Sweden, the autopsy rate between 1970 and 1982 was 87%, creating possibilities for a population-based study. METHODS: Among 23,496 clinical autopsies and 7569 forensic autopsies, 213 cases with acute thromboembolic occlusion of the SMA and intestinal infarction were identified...

Portal vein thrombosis (PVT) is an uncommon cause for presinusoidal portal hypertension. PVT can be caused by one of three broad mechanisms: (1) spontaneous thrombosis when thrombosis develops in the absence of mechanical obstruction, usually in the presence of inherited or acquired hypercoagulable states; (2) intrinsic mechanical obstruction because of vascular injury and scarring or invasion by an intrahepatic or adjacent tumor; or (3) extrinsic constriction by adjacent tumor, lymphadenopathy or inflammatory process...

Mortality rates of acute mesenteric ischemia still range between 60 and 100%. Unfortunately, retrospective series have not shown any significant improvement in mortality in the past decades. With approximately 50%, superior mesenteric artery (SMA) embolism is the most common form of acute mesenteric ischemia, followed by SMA thrombosis (approximately 25%), nonocclusive mesenteric ischemia (approximately 20%) and mesenteric venous thrombosis (approximately 5%). Clinical presentation may be unspecific, but is often characterised by an initial discrepancy between severe subjective pain and relatively unspectacular findings on physical examination...

Splanchnic arteries aneurysmatic pathology is rare, even if, in the last decades it has been noticed an increase of its incidence, owing to the worldwide use of the recent diagnostic tools as echography, TC, MR and angiography. Among visceral aneurysms those of the superior mesenteric artery (SMA) range the 5.5-8%. In the majority of cases SMA aneurysms are of mycotic etiology (60%), of atherosclerotic ones are less frequent, even if their incidence has increased in the last decades. Other causes are exceptional...

Intestinal ischemia after abdominal aortic surgery is a highly lethal complication. In order to evaluate the pathogenesis, the diagnostic modalities and the best management, in a retrospective review, 12 patients undergoing postoperative small bowel or colonic ischemic lesions were identified between 1983 and 1995. Preoperative occlusion of IMA was present in nine patients, while a selective angiography of SMA demonstrated occlusive disease of peripheral branches in two asymptomatic diabetic patients. No patent IMA was ligated...

The 70% to 80% mortality rate of patients with acute mesenteric ischemia (AMI) has remained unchanged over the past 40 years. We report here the initial results using an aggressive approach to this problem. This included the earlier and more liberal use of angiography in patients at risk and the intra-arterial infusion of papaverine for the relief of superior mesenteric artery (SMA) vasoconstriction in both nonocclusive and occlusive forms of AMI. Of the first 50 patients managed by this approach, 35 (70%) had AMI demonstrated by SMA angiography, Nineteen (54%) of these 35 patients survived, including nine of 15 patients with nonocclusive mesenteric ischemia, seven of 16 with SMA embolus, two of three patients with SMA thrombosis, and the one patient with mesenteric venous thrombosis...
