Acute mesenteric ischemia caused by spontaneous isolated dissection of the superior mesenteric artery: Treatment by intra-arterial thrombolysis and percutaneous stent placement

Spontaneous and isolated dissection of the superior mesenteric artery is a rare event with a high mortality. It has been successfully treated by surgery and in a few cases by percutaneous stent placement. We present a patient with acute mesenteric ischemia due to superior mesenteric artery dissection who was successfully treated by intra-arterial thrombolysis and endovascular stent placement.     

Endovascular stent placement for isolated spontaneous dissection of the superior mesenteric artery: report of a case

Spontaneous dissection of the superior mesenteric artery (SMA) is rare and has been reported only sporadically. The therapeutic options are either a surgical approach, which is the most frequently adopted, or simple observation. We present a patient with acute abdominal pain due to superior mesenteric artery dissection who was successfully treated by percutaneous endovascular stent placement.     

Bare Stent Implantation in Iatrogenic Dissecting Pseudoaneurysm of the Superior Mesenteric Artery

Iatrogenic arterial dissection leading to the development of dissecting pseudoaneurysms of the superior mesenteric artery (SMA) is a rare complication of angiography. Surgical and endovascular treatment options exist for this important condition. We report a case of bare stent implantation in dissecting pseudoaneurysm of the SMA that developed after angiography in a patient with acute mesenteric ischemia. Although it is rarely published, iatrogenic arterial dissection causing pseudoaneurysm can occur after diagnostic and interventional angiography. Bare stent implantation in dissecting pseudoaneurysm of the SMA could be an advantageous endovascular treatment option in selected cases due its to potential preservation of important side branches of the SMA.     

Endovascular management for isolated spontaneous dissection of the superior mesenteric artery: report of two cases and literature review

The clinical course and treatment strategies of isolated superior mesenteric artery (SMA) dissection have not been fully investigated. Two cases of uncontrolled abdominal pain caused by isolated SMA dissection were successfully treated with percutaneous endovascular stent placement. At follow-up 6 months later, computed tomography confirmed that the lesions had stabilized. The patients remained symptom free at 14- and 13-month follow-up, respectively. The present report describes these two cases of isolated SMA dissection treated successfully with percutaneous endovascular stent placement, along with a review of the related literature.     

Value of endovascular stent placement for symptomatic spontaneous isolated superior mesenteric artery dissection

Objective

To evaluate the feasibility and efficacy of endovascular stent placement for the treatment of symptomatic spontaneous isolated superior mesenteric artery dissection.

Materials and methods

This retrospective study was undertaken in 12 consecutive patients who suffered from symptomatic spontaneous isolated superior mesenteric artery dissection. Seven patients with severe clinical symptoms underwent endovascular stent placement as a primary treatment and the other 5 patients received conservative treatment. The technical results, complications and clinical outcomes were analyzed. Follow-up was performed with computed tomographic angiography.

Results

Primary endovascular stent placement was successfully performed in 7 patients with severe clinical symptoms. Successful conservative treatment was achieved in 3 patients. Endovascular stent placement was additionally performed in 2 patients with unsuccessful conservative treatment. A stent was misplaced in the false lumen in one of those two patients due to a severely stenotic true lumen. The fasting time and length of stay were significantly shorter in patients with successful endovascular therapy (median: 3 days and 5.5 days) than in those conducted conservatively (median: 9 days and 14 days) (p < 0.05). During the follow-up period (median, 21 months; range, 10–36 months), 1 patient with endovascular stent placement had recurrent abdominal pain because of the wall adherent thrombus in the proximal segment of the superior mesenteric artery during the first follow-up month. No thrombosis or stenosis was found in the lumina of the stents.

Conclusion

Endovascular stent placement is a safe and feasible therapeutic approach for symptomatic spontaneous isolated superior mesenteric artery dissection with immediate success and satisfactory outcomes.
