“…Although visceral artery PSAs (VAPAs) of the SMA are extremely uncommon, their high risk of rupture (10%-50%) and subsequent mortality (22%-40%) make their prompt diagnosis and treatment imperative. 1 , 2 , 3 VAPAs occur secondary to arterial wall disruption that can result from infection, vasculitis, fibromuscular dysplasia, trauma, or iatrogenic causes. 1 , 3 , 4 The decreased integrity of the arterial wall makes VAPAs more prone to rupture than their true aneurysmal counterparts and can prove fatal.…”

“… 6 , 7 Endovascular treatment demonstrates high technical success rates and is useful in poor surgical candidates. 3 , 7 One method of coiling uses detachable framing coils followed by progressively smaller coil placed inside the framework to achieve tight packing while negating obligation of inflow and outflow embolization with potential distal ischemia. 8 Coil embolization offers a stable treatment for exclusion of the VAPA with good short- and long-term results and complete symptom resolution and no increased risk of continued infection.…”

Visceral artery pseudoaneurysms (PSAs) are relatively rare, and cases associated with distal vasculature of the superior mesenteric artery are largely unreported. Visceral artery PSAs, without intervention, can lead to morbidity or mortality from rupture or mesenteric ischemia. Historically, open aneurysmectomy is the gold standard; however, endovascular modalities have emerged as the first-line treatment in patients who are poor surgical candidates and/or have unfavorable anatomy. Herein, we describe a case of a symptomatic PSA of the distal superior mesenteric artery treated via the transradial approach with endovascular coil embolization, showing successful aneurysmal exclusion and preservation of enteric collateral flow.

“…Although rare, VAPAs are of clinical significance because of their propensity to cause life threatening intra-abdominal or retroperitoneal haemorrhage. 5 , 6 Therefore, awareness of all aetiologies and prompt treatment are crucial for all VAPAs, whether they are symptomatic, haemorrhagic, or incidentally found. 5 …”

BackgroundVisceral arterial pseudoaneurysms (VAPAs) are rare vascular entities with serious consequences. Traditionally, they are associated with trauma, infection, and inflammatory disease, or they can arise as a post-operative complication.ReportAn 87 year old man presented with abdominal pain and was found to have a spontaneous VAPA on a computed tomography angiogram. Serial imaging 4 months previously had demonstrated no aneurysm. Between scans, warfarin was changed to apixaban for aortic valve replacement, but he had no other changes to any other medications. He required urgent endovascular coiling of the pseudoaneurysm, with satisfactory recovery and outcome.DiscussionVAPAs are extremely rare, with splenic artery VAPAs the most commonly reported. Regardless, fewer than 250 cases of splenic artery pseudoaneurysm have been reported. Superior mesenteric artery (SMA) pseudoaneurysms are the rarest type of VAPAs. Early identification and urgent treatment are warranted because of the associated high mortality risk, with a 50% risk of rupture in any given VAPA. Treatment options range from open operation to endoscopic and endovascular procedures. Apixaban has been proposed to contribute to pseudoaneurysm formation by slow and continuous bleeding that results in the formation of the pseudoaneurysm.ConclusionsSpontaneous VAPAs are extremely rare and this is the first time a VAPA has been associated with the novel oral anticoagulant “apixaban”. Urgent management of any VAPAs is important because of the high risk of rupture and potential life threatening haemorrhage.
