Abstract Visceral artery aneurysms (VAAs) are rare and affect the celiac artery, superior mesenteric artery, and inferior mesenteric artery, and their branches. The natural history of VAAs is not well understood as they are often asymptomatic and found incidentally; however, they carry a risk of rupture that can result in death from hemorrhage in the peritoneal cavity, retroperitoneal space, or gastrointestinal tract. Recent advances in imaging technology and its availability allow us to diagnose all types of VAA. VAAs can be treated by open surgery, laparoscopic surgery, endovascular therapy, or a hybrid approach. However, there are still no specific indications for the treatment of VAAs, and the best strategy depends on the anatomical location of the aneurysm as well as the clinical presentation of the patient. This article reviews the literature on the etiology, clinical features, diagnosis, and anatomic characteristics of each type of VAA and discusses the current options for their treatment and management.

Purpose: To report a case of paradoxical emboli to multiple visceral vessels treated with both mechanical (AngioJet device) and pharmacological (urokinase) thrombolysis. Methods and Results: A 72-year-old man presented with a 48-hour history of symptomatic right renal ischemia, which was treated with heparinization. Five days later, an abrupt creatinine elevation prompted arteriography, which demonstrated thromboembolism of the superior mesenteric artery (SMA) and both renal arteries. The AngioJet aspiration device was employed to successfully remove the clot from the SMA; urokinase infusion restored flow to the left kidney. At the 16-month follow-up evaluation, the patient was normotensive without medication and had a stable creatinine (1.4 mg/dL). Conclusions: Because of its speed and minimal morbidity, the AngioJet device may be an attractive alternative to surgical embolectomy or pharmacological thrombolysis in highly selected cases of acute visceral artery thromboembolism.

There is no specific duplex ultrasound (DUS) criteria for the diagnosis of inferior mesenteric artery (IMA) stenosis. This study will define the optimal duplex velocity values with the best overall accuracy (OA) in detecting ≥50% stenosis of the IMAs. Eighty-five IMAs with both DUS and mesenteric arteriography were analyzed. Eighty-five IMAs were examined: 45 were normal, 12 with <50% stenosis, eight with ≥50–69% stenosis and 15 with ≥70% stenosis (including occlusion) based on angiography. The mean peak systolic velocities (PSVs) for a normal IMA, <50% and ≥50% stenosis was 105, 215 and 392 cm/second, respectively ( P < 0.0001). The most accurate PSV in detecting ≥50% stenosis was ≥250 cm/second with a sensitivity of 90%, a specificity of 96% and an OA of 95%. The most accurate end-diastolic velocity (EDV) in detecting ≥50% stenosis was ≥80% or ≥90 cm/second, with an OA of 86%, a sensitivity of 60% and a specificity of 100%. The most accurate ratio in detecting ≥50% stenosis was ≥4 or ≥4.5 with an OA of 93%.Receiver operator curves analysis showed that the PSV was not better than EDV and PSV ratio in detecting ≥50% stenosis ( P = 0.1661 and 0.4568, respectively). In conclusion, specific IMA PSVs, EDVs and IMA/aortic systolic ratios can be used in detecting significant IMA stenosis with reasonable accuracy.

Isolated dissection of one of the mesenteric arteries without concurrent involvement of the aorta is a rare clinical entity and an unusual cause of abdominal pain. It usually involves one artery, most commonly the superior mesenteric artery (SMA) followed by the coeliac artery. We are reporting a rare case where both coeliac and SMA were showing dissection. We are reporting a case of 60-year-old hypertensive male who came with worsening abdominal pain for 5 days; CT scan showed coeliac and SMA dissection without any imaging evidence of intestinal ischaemia. He was successfully managed medically with bowel rest and anticoagulation. Two weeks of follow-up CT scan showed no progression or thrombus formation. For complicated cases, percutaneous transluminal angioplasty of a visceral artery or open surgical exploration or hybrid approach is required. However, for stable uncomplicated cases, medical therapy alone is sufficient.

AbstractThe abdominal viscera blood supply is derived from anterior branches of the abdominal aorta. Visceral artery aneurysms (VAAs) include aneurysms of the following arteries and their branches: the celiac artery, the hepatic artery, the splenic artery, the superior mesenteric artery, the inferior mesenteric artery, the pancreaticoduodenal artery, and the gastroduodenal artery. Overall VAAs comprise < 2% of all types of arterial aneurysms. Asymptomatic VAAs are now being encountered more frequently due to the widespread use of advanced diagnostic abdominal imaging. The incidental finding of a VAA frequently leaves clinicians with a dilemma as to the best course of management. The focus of this review is on current treatment options and management guidelines for both symptomatic and asymptomatic VAAs.
