“…The macroscopic findings of the resected specimen showed an aneurysm (Figure a). The histological findings of the resected aneurysm resembled a so‐called “segmental arterial mediolysis” (Figure b) . The patient was discharged from our hospital on day 7 with no postoperative complications.…”

Laparoscopic surgery for the treatment of a ruptured visceral artery aneurysm is recognized as a challenging procedure. Here, we describe our experience with laparoscopic surgery to treat a ruptured aneurysm of the right gastric artery. A 72-year-old woman was diagnosed with intra-abdominal hemorrhage caused by a ruptured aneurysm of the right gastric artery. Transcatheter arterial embolization failed because the right gastric artery could not be cannulated. Therefore, we performed laparoscopic surgery. Using laparoscopy, we detected that the bleeding from the aneurysm had ceased; thus, the planned procedure was successful. The operative time and intraoperative blood loss were 100 min and 5 mL, respectively. The patient was discharged 7 days after surgery. Laparoscopic surgery after the failure of transcatheter arterial embolization is a suitable and safe procedure for ruptured visceral artery aneurysms, provided the circulatory dynamics are stable as a result of the temporary cessation of bleeding from the ruptured aneurysm.

“…Ushijima et al. deemed the etiology of visceral artery aneurysms, other than pseudoaneurysms, to be “segmental arterial mediolysis” due to the cystic dissection of the arterial medium . As a result, even visceral artery aneurysms, other than pseudoaneurysms, are considered to rupture easily.…”

“…[1][2][3][4][5][6] Segmental arterial mediolysis also causes PDA aneurysms. 7) The incidence of PDA aneurysm rupture is up to 65%, 1,3,6,8) and the risk of rupture appears to be unrelated to the size of the aneurysm. 4) In a review of 88 patients with PDA aneurysms, 53 experienced rupture, which was fatal in 26 (49.1%).…”

“…Catheter-guidewire manipulation in cases with subacute phase dissecting lesions may carry the risk of aortic rupture. 7) However, recent advanced catheter-guidewire technologies allow safe endovascular treatment even in such cases. We chose the left brachial artery approach because catheter insertion into the true lumen seemed straightforward.…”

A 51-year-old man with a ruptured pancreaticoduodenal artery (PDA) aneurysm caused by compression of the celiac artery by the median arcuate ligament and aortic dissection involving the celiac axis was transferred to our hospital for endovascular treatment. A 4-F catheter was advanced into the superior mesenteric artery through the narrow true lumen via the left brachial artery, and coil embolization of the aneurysm was successfully performed. In this case, rapid increase of blood fl ow in the superior mesenteric artery, which compensated for the decreased celiac blood fl ow by aortic dissection, increased hemodynamic stress on the PDA, leading to aneurysmal rupture.

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.
