Abstract:
Objective To evaluate the safety and effectiveness of treating the endovascular stents placement for spontaneous isolated dissection of splanchnic artery ( SIDSA).Methods Sixteen consecutive patients with diagnosis of SIDSA through CTA and DSA were retrospectively analyzed .All patients had acute persistent abdominal pain and treated by endovascular stents placement.The serious complications and symptoms improvement were reviewed after the operation.The symptoms recurrence and repeated color doppler ultrasonography and CTA were also reviewed in the follow up.Results Twelve superior mesenteric artery ( SMA) dissection and four celiac artery ( CA) dissection were diagnosed among sixteen patients.The dissection length was 1.07 to 11.87 cm and the median length was 3.93 cm.The distance from the original dissection to the orifice of superior mesenteric artery or celiac artery was 0.50 to 6.44 cm and the median was 1.98 cm.Eight stent-grafts and 3 bare stents were successfully implanted in 11 patients.One case with celiac dissection was failed to treat because of the severe compression of true lumen and the guide wire cann′t cannulate to the distal true lumen.Four patients with superior mesenteric artery dissection gave up interventional therapy , Among these 4 patients , 2 patients had small tear site and small false lumen , 1 patient had extremely long dissection , and one case had blood supply of target organs from both true and false lumen.No severe complications such as hemorrhage , intestinal necrosis , hepatic failure and splenic necrosis occurred during the eleven successful endovascular interventions.The abdominal pain in 10 cases was disappeared or significantly relieved , 1 case with superior mesenteric vein thrombosis and severe intestinal ischemia before intervention underwent intestinal resection for necrosis.The follow up period was 1 to 74 months in eleven successful cases , and the median follow-up period was 16 months.One patient with SMA dissection after endovascular treatment was died of sudden stroke three months later .Others had satisfactory outcome and the repeated color doppler ultrasonography and CTA were normal .Conclusions Endovascular stents placement is a safe and effective therapy for symptomatic spontaneous isolated dissection of splanchnic artery.
