Hybrid Retrograde Endovascular Repair of a Rapidly Expanding Chronic SMA Dissection

BackgroundNeurofibromatosis type 1 (NF-1) is an autosomal dominant disease and arteriovenous abnormalities are a well-recognized complication. There are several case reports of ruptured aneurysms; however, among them, reports of superior pancreaticoduodenal artery (PDA) and superior mesenteric artery (SMA) aneurysms are rare. We experienced the case of ruptured PDA and SMA aneurysms in a patient of neurofibromatosis type I successfully treated by endovascular treatment.Case presentationA 55-year-old woman with NF-1 came to our hospital with abdominal pain and vomiting. Enhanced abdominal computed tomography revealed a hematoma in the retroperitoneum and an aneurysm in the head of the pancreas. Angiography was performed, and a ruptured aneurysm was suspected the periphery of the PDA, and we embolized it using coils. However, on postoperative day 2, the hemoglobin level decreased, and a branch of the SMA was ruptured. She underwent embolization using coils again and discharged on postoperative day 27 without any further hemorrhage.ConclusionsTo our knowledge, this is the first successfully treated case of ruptured SMA and PDA aneurysms in a patient with NF-1.

A Hybrid Approach to Treatment of a Superior Mesenteric Artery Aneurysm

A 54-year-old woman with a mycotic superior mesenteric artery (SMA) aneurysm underwent emergent aneurysm resection with a great saphenous vein bypass. Follow-up computed tomography revealed a rapidly growing recurrent SMA aneurysm at the stump. Under the diagnosis of recurrent pseudoaneurysm of SMA with a fragile stump, we performed an open dual arterial bypass using indocyanine green fluorescence angiography and endovascular coil embolization. Subsequently, the patient's recurrent mycotic SMA aneurysm was successfully managed without mesenteric ischemic complications. This method may help prevent fatal mesenteric ischemia during SMA aneurysm surgery.

This case report describes an unusual case of upper gastrointestinal (UGI) bleeding caused by a ruptured superior mesenteric artery (SMA) aneurysm in the duodenum in a patient with rheumatoid arthritis. The patient presented with UGI bleeding and hemorrhagic shock. Emergency UGI endoscopy could not identify the source of the bleeding because of excessive blood clots under the second portion of the duodenum. An SMA aneurysm with active contrast extravasation was diagnosed by computed tomography. The aneurysm, together with the fourth portion of the duodenum and the proximal portion of the jejunum, was surgically resected, and the SMA was skeletonized. On postoperative day 15, the patient was discharged from hospital under satisfactory conditions. Rheumatoid arthritis has been known to cause a wide spectrum of manifestations, and an SMA aneurysm is an unusual extra-articular manifestation. An SMA aneurysm rupture presenting as upper gastrointestinal bleeding is a rare complication with a high mortality rate. The clinician must be alert to this potential issue to achieve rapid diagnostic confirmation, and immediate surgical or radiological intervention.

PC174. Presentation and Management of a Rare and Fatal Disease: Saccular Superior Mesenteric Artery Aneurysms

Superior mesenteric artery (SMA) aneurysms are rare. However, patients are frequently symptomatic on presentation and require urgent repair. SMA aneurysms have the potential for severe complications, including thrombosis or rupture, resulting in acute mesenteric ischemia and death. In patients with adhesions secondary to prior abdominal surgery, traditional open exposure of the aneurysm neck via dissection at the base of the transverse colon mesentery may be technically difficult. Endovascular exclusion of visceral artery aneurysms using covered stent grafts presents a reasonable alternative to the morbidity associated with laparotomy. We report an interesting case of a patient with a large SMA aneurysm and multiple prior laparotomies treated percutaneously with a combined expanded polytetrafluoroethylene/nitinol self-expanding stent-graft allowing maintenance of end-organ perfusion and bowel viability.
