Stenting of Superior Mesenteric Artery Chronic Total Occlusions in Patients with Chronic Mesenteric Ischemia: Technical and Clinical Outcomes Grilli CJ, Fedele CR, Tahir OM, Velez JD, Wrigley C, McGarry M, Ali MA, Agriantonis D, Kimbiris G, Garcia MJ, Leung DA Christiana Care Health System, Newark DE/US
Chronic Mesenteric Ischemia • Bowel manifestation of PAD • Atherosclerosis • hardening of arteries • plaque buildup blockage • Blockage of arteries supplying bowel • pain after eating • fear of food • weight loss • death
Chronic Mesenteric Ischemia • Bowel arteries • celiac artery • superior mesenteric artery • inferior mesenteric artery • Grading arterial blockages: • progressive atherosclerotic plaque • stenosis: 60-99% blockage • amenable to endovascular stenting • occlusion: 100% blockage • usually managed surgically
Background 1. Sreenarasimhaiah J: Chronic Mesenteric Ischemia. Best Pract Res ClinGastroenterol. 19(2):283-95, 2005
Purpose • To investigate the feasibility and effectiveness of endovascular stenting of superior mesenteric artery occlusions (100% blockages) in patients with chronic mesenteric ischemia
Methods • 47 patients • 18 male, 29 female • mean age 73 yrs, range 44-87 • All patients with clinical symptoms of CMI > 1mo
ResultsPROCEDURE SUCCESS • Achieved in 41/47 (87%) • 6 unsuccessful procedures: • 2 went on to bypass • 3 received celiac stents • 1 lost to follow-up
ResultsINITIAL SYMPTOM IMPROVEMENT • Symptom Improvement < 30 d • 4 point scale • significant improvement • partial improvement • no change • worsening of symptoms N=41
ResultsFOLLOW-UP BY ULTRASOUND • Primary patency (months): • 97% @ 12 • 75% @ 24 • Recurrent blockage of SMA: • 7 patients • all had repeat endovascular procedures • Secondary patency • 100% @ 12 • 97% @ 24
ResultsSYMPTOMS • Symptom-free • 100% @ 12 mo • 88% @ 24 mo
Conclusions • Endovascular stenting of complete blockages of the SMA is a safe and effective procedure • minimally-invasive • good technical success rate • easily repeatable • excellent clinical outcomes
