Abstract:
Objective To study the clinical characteristics and treatment strategy for isolated dissection of the superior mesenteric artery (SMA).Methods Clinical data of 19 consecutive patients with IDSMA were retrospectively analyzed.There were 15 men and 4 women.The mean age was 56 ± 12 (41-84) years old.Fifteen patients presented with abdominal pain and 4 patients had no symptom.The dissections were diagnosed by contrast-enhanced computed tomography in 18 patients and ultrasonography in 1 patient.Results The dissections were located at the anterior wall of the curvature part of the SMA in all 19 patients.Asymptomatic patients underwent conservative management.One asymptomatic patient with aneurysmal dilation was managed by stent and the 15 symptomatic patients underwent endovascular management.During the mean 7-46 (21 ± 10) months follow-up period,all patients were asymptomatic with patency of SMA.Conclusions The dissection was located at the anterior wall of the curvature part of the SMA.Conservative management can be applied to the asymptomatic patients.For symptomatic patients without intestinal necrosis or artery rupture,stent implantation is recommended,and the curvature of SMA should be covered completely.Endovascular spasmolysis is helpful in relieving pain.
