Celiac Artery Dissection and Retroperitoneal Hemorrhage in Median Arcuate Ligament Syndrome Treated With a Stent and Transcatheter Arterial Embolization: Preprocedural 4-Dimensional Computed Tomography Angiography Assessment

A 61-year-old man presented with retroperitoneal hemorrhage caused by an aneurysm rupture of the pancreaticoduodenal arcade (PDA), and acute celiac artery dissection distal to celiac axis stenosis. Owing to the gradual growth of the false lumen, we planned to deploy a stent to the celiac artery dissection and embolize the PDA aneurysm. Prior to stent placement, we assessed the acute celiac artery dissection distal to the stenosis using four-dimensional computed tomography (CT) angiography through expiration/inspiration/expiration cycle. We diagnosed median arcuate ligament syndrome considering that the celiac axis showed a hooked narrowing at end-expiration, and the compression decreased at end-inspiration. Additionally, the true lumen distal to the stretched axis dilated in the inspiration phase. Therefore, we could advance a catheter into the true lumen during inspiration and successfully deploy a stent. Subsequently, laparoscopic median arcuate ligament release was performed after the stent deployment. A postoperative CT scan showed good patency in the stent, with disappearance of the blood filling the false lumen and with reduced celiac axis stenosis.

Pancreatic head resections in the setting of celiac axis stenosis: Case report and review of literature

Introduction: Ischemic complications are a notable cause of morbidity in patients after pancreatic head resections. Stenosis of celiac axis in patients undergoing pancreatoduodenectomy requires further perioperative attention. Case report: We present a patient with pancreatic head malignancy scheduled for Whipple procedure in the setting of hemodynamically significant celiac axis stenosis. Despite release of the artery from compression by median arcuate ligament, elevation of liver function tests on the first postoperative day was noted. Endovascular stenting was performed on the same day with significant radiological improvement and subsequent normalization of laboratory values. The patient had no further postoperative complications. Conclusion: Fast recognition of ischemic complications after pancreatic head resection is crucial. Even postoperatively, endovascular intervention might be a feasible treatment modality of celiac axis stenosis in selected patients who undergo pancreatoduodenectomy.

Pancreaticoduodenectomy with reconstructing blood flow of the gastric conduit after esophagectomy with concomitant celiac axis stenosis: a case report

Background Pancreaticoduodenectomy after esophageal resection is technically difficult, because blood flow of the gastric conduit should be preserved. Celiac axis stenosis (CAS) is also a problem for pancreaticoduodenectomy, because arterial blood supply for the liver comes mainly through the collateral route from the superior mesenteric artery (SMA) via the gastroduodenal artery (GDA). Herein, we report the case of a patient with pancreatic head cancer who underwent a pancreaticoduodenectomy after esophagectomy with concomitant CAS. Case presentation A 76-year-old man with pancreatic head cancer was referred to our department. He had a history of esophagectomy with retrosternal gastric conduit reconstruction for esophageal cancer. Computed tomography showed severe CAS and a dilated collateral route between the SMA and the splenic artery (SPA). We prepared several surgical options depending on the intraoperative findings, and performed radical pancreaticoduodenectomy with concomitant resection of the distal gastric conduit. The right gastroepiploic artery (RGEA) of the remnant gastric conduit was fed from the left middle colic artery (MCA) with microvascular anastomosis. Despite CAS, when the GDA was dissected and clamped, good blood flow was confirmed, and the proper hepatic artery did not require reconstruction. The patient was discharged on postoperative day 90. Conclusions We successfully performed radical pancreaticoduodenectomy after esophagectomy with concomitant CAS, having prepared multiple surgical options depending upon the intraoperative findings.
