PurposeTo evaluate the safety and outcomes of endovascular recanalization of chronic total occlusions (CTOs) of the superior mesenteric artery (SMA) in patients with chronic mesenteric ischemia (CMI).Materials And MethodsA single-institution retrospective review was performed of 47 consecutive patients (18 male, 29 female) who underwent endovascular stent placement for CTOs of the SMA between February 2006 and November 2012. All patients had symptoms of CMI. Procedural and follow-up data were collected for assessment of technical success, safety, and outcome.ResultsTechnical success was achieved in 41 of 47 patients (87%). Forty-two of the 47 procedures were performed from a femoral approach. Fifteen patients underwent concurrent revascularization of the celiac artery. All patients who underwent successful recanalization reported symptomatic improvement. Kaplan-Meier analysis revealed primary freedom from symptomatic recurrence of 95% at 12 months and 78% at 24 months. Symptomatic recurrence was observed in seven patients, all of whom underwent successful assisted or secondary endovascular procedures. Secondary freedom from symptomatic recurrence rates were 100% at 12 months and 88% 24 months. There were three (7%) minor access-related complications and no major complications.ConclusionsEndovascular stent-assisted recanalization of chronic SMA occlusions is safe and effective, with an acceptable rate of technical success and excellent midterm clinical outcomes.Copyright © 2014 SIR.
