OBJECTIVE: To evaluate the technical feasibility and clinical outcome of percutaneous aspiration embolectomy for embolic occlusion of the superior mesenteric artery (SMA). MATERIALS AND METHODS: Between January 2010 and December 2013, 9 patients with embolic occlusion of the SMA were treated by percutaneous aspiration embolectomy in 2 academic teaching hospitals. The aspiration embolectomy procedure was performed with the 6-Fr and 7-Fr guiding catheter. Thrombolysis was performed with urokinase using a multiple-sidehole infusion catheter. The clinical outcome was investigated retrospectively. RESULTS: Superior mesenteric artery occlusion was initially diagnosed by computed tomography (CT) in all patients, and all patients had no obvious evidence of bowel infarction on CT scan. Percutaneous aspiration embolectomy was primarily performed in 6 patients, and thrombolysis was initially performed in 3 patients. In 3 patients who received primary thrombolysis, percutaneous aspiration was undertaken because the emboli were resistant to urokinase. Complete angiographic success was achieved in 6 patients and partial angiographic success was accomplished in 3 patients. One patient underwent bowel resection. One patient died of whole bowel necrosis and sepsis, and 8 patients survived without complications. CONCLUSION: Percutaneous aspiration embolectomy is a useful tool in recanalization of embolic occlusion of the SMA in select patients.

Since the introduction of pancreas transplantation more than 40 years ago, surgical techniques and immunosuppressive regiments have improved and both have contributed to increase the number and success rate of this procedure. However, graft survival corresponds to early diagnosis of organ-related complications. Thus, knowledge of the transplantation procedure and postoperative image anatomy are basic requirements for radiologists. In this article, we demonstrate the imaging spectrum of pancreas transplantation with enteric exocrine drainage.

We report a rare case of aneurysm of splenic artery arising anomalously from the superior mesenteric artery (SMA). The aneurysm was treated successfully by coil embolization of the splenic artery distal to aneurysm and then deploying a stent graft in the SMA. A combination of stent graft and coil embolization for the treatment of aberrant splenic artery aneurysm has been reported only once. We describe the imaging findings and the endovascular procedure in this patient.

Acutely aggravated dissecting flap and consequent occlusion of the superior mesenteric artery (SMA) by simple contrast passage during initial angiography for percutaneous stent placement is a uncommon event, which usually is not reported. After analysis of many factors that underlie development of such complications, we present herein one case of successful treatment of isolated SMA dissection and its complications with favorable outcomes during 25 months follow-up after percutaneous stent placement.

Isolated spontaneous dissection of the superior mesenteric artery (SMA) without aortic dissection is a rare cause of acute mesenteric ischemia. A sudden decrease of intestinal blood flow can lead to fatal complications such as ischemic necrosis, shock, and death. Therefore, early diagnosis and therapeutic approach before the occurrence of intestinal infarction are the most important factor to determine the patient's prognosis. A 52-year-old male presented with postprandial periumbilical pain, and isolated spontaneous dissection of the superior mesenteric artery with mural thrombus was detected by abdominal computed tomography with contrast enhancement. By the percutaneous implantation of vascular metallic stent via femoral artery, he was treated successfully. We report a case of isolated spontaneous dissection of the SMA treated by a percutaneous endovascular stent replacement with a review of literature.

Mesenteric lymphangiomas are rare abdominal masses that are seldom associated with small bowel volvulus, and especially in adult patients. We report here on an unusual case of small bowel volvulus that was induced by a mesenteric lymphangioma in a 43-year-old man who suffered from repeated bouts of abdominal pain. At multidetector CT, we noticed whirling of the cystic mesenteric mass and the adjacent small bowel around the superior mesenteric artery. Small bowel volvulus induced by the rotation of the mesenteric lymphangioma was found on exploratory laparotomy. Lymphangioma should be considered as a rare cause of small bowel volvulus in adult patients.

Superior mesenteric artery (SMA) syndrome is rare disorder, which is caused by a reduction in the aortomesenteric angle causing a duodenal obstruction. It is usually occurs after a period of weight loss, nausea, and vomiting by a partial obstruction of the third portion of the duodenum. If conservative management fails then a laparotomy with a duodenojejunostomy is indicated. Recently, a minimally invasive or laparoscopic approach to the retroperitoneum or duodenal detachment was introduced. Although the role of a laparoscopy in managing SMA syndrome is not clearly defined, a laparoscopic duodenojejunostomy may be an alternative approach to the surgical treatment of SMA syndrome cases. Two cases of superior mesenteric artery syndrome that were treated laparoscopically after medical therapy failure are described. The 4-port procedure was performed. A dilated bowel on the third portion of the duodenum was observed below the transverse mesocolon and to right of the superior mesenteric artery. A proximal loop of the jejunum was anastomosed to the duodenum using an endoscopic GIA stapler. The surgery time and hospital length of stay were acceptable. No complications were encountered in this study. A laparoscopic duodenojejunostomy is a feasible alternative option for treating SMA syndrome. It provides the benefits of being a definitive and minimally invasive surgical technique in a duodenal obstruction.
