Abstract:
Objective To investigate the clinical features of spontaneous isolated superior mesenteric artery dissection (SISMAD), and to discuss its interventional therapy. Methods The clinical data of 10 patients with SISMAD, who were admitted to authors' hospital to receive interventional treatment during the period from January 2006 to June 2014, were retrospectively analyzed. All the 10 patients were males, aged 44-66 years with a mean of (53±8) years. Clinically, all patients presented with acute-onset abdominal pain or pain around umbilicus, as the effect of conservative treatment was poor, implantation of self-expandable bare stent was carried out. Results Successful implantation of self-expandable bare stent was accomplished in all 10 patients;only one stent was used in 7 patients and 2 stents were used in 3 patients. The blood in the true lumen of superior mesenteric artery (SMA) restored and the residual stenosis extent was less than 15%. The technical success rate was 100%. The abdominal pain was relieved in 8 patients on the operative day after treatment, and in 2 patients the abdominal pain was relieved in 2 days after treatment. All the patients were followed up for 7-71 months (mean of 36 months) and the follow-up rate was 100%. After the treatment patients had no symptoms of abdominal discomfort. Contrast-enhanced CT scan performed at 6, 12 and 24 months after the treatment showed that SMA and stent was patent and no aneurysmal dilatation was observed. Conclusion For the treatment of SISMAD endovascular implantation of self-expandable bare stent is clinically safe and feasible, and its long-term effect is satisfactory.
