A true isolated superior mesenteric artery (SMA) dissection is a rare occurrence. The increasing use of diagnostic imaging studies has resulted in this rare disease being more recognized. A 68-year-old Caucasian female presented with sharp upper abdominal pain. Computed tomography (CT) of the abdomen showed dissection with thrombosis in the proximal SMA. Conservative management with bowel rest, blood pressure control, and anticoagulation relieved her symptoms. Follow-up CT showed stable dissection. Physicians should consider the diagnosis of isolated spontaneous SMA dissection after excluding more common causes. The optimal management pathway has not been firmly established. Conservative management with anticoagulation appears to be a safe first-line therapy in selected patients.

Abstract Background: Spontaneous isolated superior mesenteric artery dissection (SISMAD) is a rare vascular disorder, and the treatment strategies remain controversial. This study aimed to compare outcomes of conservative and endovascular treatments in symptomatic patients with SISMAD. Methods: Forty-two consecutive SISMAD patients who were admitted to a single center between October 2009 and May 2018 were enrolled in this study. Based on their symptoms, 15 had conservative treatment, and 27 had endovascular treatment. The baseline characteristics, treatments, and follow-up results of the conservative group and endovascular group were analysed. Results: The rates of symptom relief were 93.3% in the conservative group and 96.3% in the endovascular group. The procedure-related complications in the endovascular group included one case of pseudoaneurysm formation in the left brachial artery. During the follow-up period (median 28.5 months), a higher proportion of patients in the conservative group had symptom recurrence (42.9% in the conservative group versus 4.8% in the endovascular group, p < 0.001). Four patients in the conservative group and one patient in the endovascular group had additional endovascular intervention during follow-up. Compared with the conservative group, patients in the endovascular group had statistically significantly longer symptom-free survival ( p = 0.014) and a higher rate of superior mesenteric artery (SMA) remodeling ( p < 0.001). Conclusions: For symptomatic SISMAD, endovascularly treated patients had a lower rate of symptom recurrence and a higher rate of SMA remodeling in the long term. Prospective, multi-center studies are needed to confirm the long-term outcomes of both treatments.

This study aimed to compare outcomes of conservative and endovascular treatments in symptomatic patients with SISMAD. Methods: Forty-two consecutive SISMAD patients between October 2009 and May 2018 in a single center were enrolled in the study. Based on their symptoms, 15 had conservative treatment and 27 had endovascular treatment. The baseline characteristics, treatments, and follow-up results of the conservative group and endovascular group were analyzed. Results: The rate of symptom relief was 93.3% in the conservative group and 96.3% in the endovascular group, respectively. The procedure-related complications in the endovascular group included one case of pseudoaneurysm formation in the left brachial artery. During the follow-up period (median 28.5 months), a higher proportion of patients in the conservative group had symptom recurrence (42.9% in the conservative group versus 4.8% in the endovascular group, p < 0.001).

Conclusions: For symptomatic SISMAD, endovascularly treated patients had a lower rate of symptom recurrence and a higher rate of SMA remodeling in the long term. Endovascular treatment should be considered as the first-line treatment of SISMAD.

Prognostic Prediction

Background Spontaneous superior mesenteric artery (SMA) dissection is rare cause of acute abdomen. Time-dependent change of SMA dissection has not been established. Purpose To determine Sakamoto classification (SC) type of acute and chronic SMA dissection (aSMAD and cSMAD) to predict the treatment methods and outcome. Material and Methods From April 2003 to March 2017, unenhanced and contrast-enhanced CT were used to diagnose acute symptomatic or chronic asymptomatic SMA dissection in 25 consecutive patients without aortic dissection. Correlations between SCs and treatment methods and outcomes were investigated. Results All 13 patients with aSMAD initially received conservative treatment. Initial SCs in aSMAD were type I = 1, type III = 9, and type IV = 3. Three of nine initial type III and two of three initial type IV changed to type I at follow-up. One of nine type III changed to type II at follow-up. Ohers did not change. One with initial type III required vascular repair, so the final SC was not available. Three patients required bowel resection. In cSMAD of 12 patients, the initial/final SC were type I and IV in ten and two patients, respectively, without change during follow-up. cSMAD was significantly older than aSMAD. The initial length of dissection of aSMAD was longer than in the cSMAD group. In aSMAD, the final length of dissection was significantly shorter than in the initial computed tomography scan. Conclusion Initial SC differed significantly between aSMAD and cSMAD. Initial SC types in aSMAD were type III and IV mainly, and changed during the observation period. In cSMAD, SC types were I and IV without change.

Purpose. We report the clinical outcomes of patients with spontaneous isolated dissection of the superior mesenteric artery (SIDSMA) who were treated conservatively. Materials and Methods. A retrospective review was performed in 14 patients from 2006 to 2016 with SIDSMA. Their clinical features and computed tomographic angiography (CTA) characteristics, treatment methods, and clinical outcomes were analyzed. The mean age was 53.6 (range, 41–73) years, and the mean follow-up duration was 20.6 (range, 1–54) months. Conservative management was the primary treatment if no bowel ischemia or arterial rupture was noted. Results. The mean initial abdominal visual analog pain score was 7 (range, 5–9) in seven patients. The mean total duration of abdominal pain was 10.2 days (range, 2–42 days) in 10 patients. The mean percentage stenosis of the dissected SMA at the initial presentation was 78.8% in 14 patients. Complete obstruction of the SMA at the initial presentation was evident in 4 of the 14 patients (28.6%). Conservative management was successful in all 14 patients. None of the 14 patients developed bowel ischemia or an infarction. Abdominal pain did not recur in any patient during follow-up (mean, 20.6 months; range, 1–54 months). Conclusion. Conservative management was successful for all SIDSMA patients, even those with severe compression of the true lumen or complete obstruction of the dissected SMA.

Spontaneous Dissection

AbstractIsolated spontaneous dissection of the mesenteric artery in the absence of involvement of the aorta or its branches is an uncommon vascular entity. It is generally seen in males and presents with gastrointestinal symptoms due to mesenteric ischemia. However, asymptomatic cases are increasingly being diagnosed due to increased use of computed tomography (CT) angiography. The course is usually self-limiting, and conservative management with bowel rest, strict blood pressure control, anticoagulants, sedatives for pain, and close observation usually suffices. Surgery or endovascular stenting is usually reserved for those exhibiting bowel ischemia or impending rupture. We report a case of a young female with isolated spontaneous mesenteric artery dissection with thrombus, which did not improve with medical therapy and was managed promptly by surgery due to the presence of bowel ischemia.

Superior Mesenteric Artery Dissection

Spontaneous isolated celiac or superior mesenteric artery (SMA) dissection (SICMAD) is a rare clinical entity. Not much is known about the natural history and appropriate treatment. We retrospectively queried a prospectively collected institutional radiology database for all patients diagnosed with SICMAD from 1990 to 2017. We identified 42 arteries in 40 patients (83.3% male), mean age 54.8 ± 10.9 years, consisting of 24 celiac arteries and 18 SMA. SMA lesions were longer than celiac lesions (5.15 ± 3.81 vs 2.38 ± 1.40 cm, p = 0.008). Thirty-one patients had follow-up; mean follow-up was 4.9 ± 4.8 years. Morphologic improvement was seen in 20 (48%) arteries. Sakamoto IV lesions were more likely to remodel (OR: 11.26, 95% CI: 1.13, 588.26, p = 0.039), and Sakamoto II lesions less likely to remodel (OR: 0, 95% CI: 0.00, 0.93, p = 0.05). Patients received an average of 2.35 scans during follow-up. Symptom resolution occurred in all symptomatic patients, and 16% of patients had recurrence of symptoms. Follow-up CT scans revealed a stable arterial diameter for the majority of patients. In conclusion, the majority of patients with SICMAD improve with medical therapy alone. Aneurysmal dilatation is uncommon.
