This study reviewed outcomes in patients treated surgically for CMI by open treatment (OT) and endovascular treatment (ET), analyzing risk factors for endovascular failure.Methods Clinical data for 36 patients treated for CMI from 2007 to 2017 were retrospectively analyzed. The study’s primary endpoint was symptom-free survival. The secondary endpoint was the primary technical success for endovascular and open surgical treatments. Risk factors for endovascular failure were identified by using univariate analysis.Results Patients were analyzed as treated: 21 patients (58.3%) in the ET and 15 (41.6%) in the OT group. Overall, 20 patients (56%) presented with abdominal angina, 9 (25%) with rest pain, and 7 (19%) without symptoms. An ET was initially attempted in 31 patients (86.1%). The conversion rate from ET to OT was 32.3%, which resulted in a primary technical success of 67.6% in ET and 100% in OT. Six patients from the ET group (19.3%) required surgical revision due to restenosis. One-year (OT 91.6% vs. ET 96.8%; n.s.) and three-year primary patency (OT 91.6% vs. ET 80.6%; n.s.) as well as 3-year symptom-free survival did not differ between the groups (OT 62.5% vs. ET 69.4%; n.s). Overall, in-hospital mortality was 2.8% (n?=?1), which was not statistically different between the groups (OT 6% vs. ET 0%; n.s.). High-grade stenosis of the superior mesenteric artery tended to be associated with higher technical failure (P?=?0.06).Conclusions ET showed a comparable perioperative outcome with higher technical failure. OT was distinguished by excellent early and late technical success. 收起
