Research progress of treatment options on spontaneous isolated superior mesenteric artery dissection based on computed tomography imaging classification

Because of the low incidence rate, spontaneous isolated superior mesenteric artery dissection (SISMAD) is once considered as a rare disease. In recent years, with the widespread application of enhanced computed tomography (CT), reports of SISMAD have increased. At present, there is no consensus on the optimal treatment of SISMAD, and there are various imaging classifica-tions based on CT. However, clinical management strategy for SISMAD according to any imaging classification based on CT has not yet been acknowledged. Foreign scholars believe that conservative treatment can improve symptoms in most SISMAD patients, while Chinese scholars prefer endo-vascular intervention. The authors review the research progress of treatment options on SISMAD based on computed tomography imaging classification.
