Presentation, treatment, and outcomes in patients with spontaneous isolated celiac and superior mesenteric artery dissection



Presentation, treatment, and outcomes in patients with spontaneous isolated celiac and superior mesenteric artery dissection



Vascular Medicine 22(6): 505-511



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.
