Abstract:
Purpose:Spontaneous isolated dissection of the celiac artery (SID-CA) and superior mesenteric artery (SID-SMA) are rare vascular diseases with similar presentation, yet comparative studies have not been reported. In this study, we compared their characteristics with the aim of providing insights into their etiology.
Materials and Methods:Patients diagnosed with symptomatic SID-CA and SIDSMA between July 2009 and December 2018 were included. Demographics, clinical presentation, radiologic findings, treatment strategies, and outcomes were analyzed.
Results:Twenty-one patients with SID-CA and 40 patients with SID-SMA were compared. Demographics and initial abdominal pain characteristics were similar, but pain severity was significantly higher and associated mean fasting time was significantly longer in patients with SID-CA than in those with SID-SMA (fasting time 3.2 vs 2.1 days, P=0.001). Most patients were successfully treated conservatively without recurrent pain or aneurysmal dilatation, but 33.3% patients with SID-CA and 17.5% with SID-SMA required endovascular intervention. More favorable remodeling in terms of dissection regression on follow-up computed tomography was found after stenting, where patients with SID-CA showed better remodeling than those with SID-SMA. The overall median follow-up period was 22-31 months, while for patients with stent insertion, it was 55-77 months, and no stent occlusions were found during this period.
Conclusion:Patients with SID-CA presented with severer and longer-duration abdominal pain than those with SID-SMA. Stenting in both groups showed good long-term patency and favorable remodeling, with a higher regression rate for SIDCA. Based on our results, patients with SID-CA may benefit more from active endovascular intervention.
