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.

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.

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).

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. Endovascular treatment should be considered as the first-line treatment of SISMAD.

Superior Mesenteric Artery Dissection

Objective: There is no detailed information available about trend in the morphological change after conservative medical treatment in patients with symptomatic spontaneous isolated superior mesenteric artery dissection (SISMAD). Methods: We enrolled 27 consecutive patients with symptomatic SISMAD who underwent conservative medical treatment between 2006 and 2015. The long-term prognosis, natural history, and serial follow-up computed tomography (CT) findings of risk factors of rupture such as arterial diameter and false lumen enhancement were retrospectively assessed. Results: Spontaneous isolated superior mesenteric artery dissection usually developed in middle-aged men around 50 years old who had a history of smoking. Follow-up CT was performed at 1 to 6 months, 7 to 12 months, and after 12 months. Superior mesenteric artery (SMA) maximum diameter was 10.3 mm (quartile 9.5-11.3) on initial CT and expanded in 47.1% patients during 1- to 6-month follow-up, which decreased over time ( P < .001 at 7- to 12-month follow-up, P = .001 after 12-month follow-up). On the other hand, false lumen enhancements were revealed in 9 (33.3%) patients on initial CT. The size of false lumen enhancement was expanded in the longest diameter in 35.3% patients and in shortest diameter in 29.4% during 1- to 6-month follow-up. However, the size of false lumen decreased in all patients after 12-month follow-up. All patients were alive without arterial aneurysm rupture and hospital readmission during the median of 523 days (170-799) study period. Conclusion: We demonstrated that both SMA maximum diameter and false lumen enhancement were transiently expanded in some patients during 6-month follow-up, but no longer expanded after 12-month follow-up. Patients with symptomatic SISMAD could be treated medically with scheduled careful follow-up CT evaluations.

Superior Mesenteric Artery Dissection

Abstract Background Most patients with isolated superior mesenteric artery (SMA) dissection are successfully managed conservatively. However, some patients require more invasive treatment. Case presentation We herein describe a 45-year-old man with isolated SMA dissection. He initially underwent conservative treatment. However, because of persistent abdominal angina, we considered the need for surgical revascularization. He was successfully treated by endarterectomy, patch angioplasty, and retrograde open mesenteric stenting. The abdominal angina was stabilized thereafter. Conclusions The combination of endarterectomy, patch angioplasty, and retrograde open mesenteric stenting is useful for isolated SMA dissection, and long patency can be expected for some patients.
