Summary
Isolated superior mesenteric artery (SMA) dissection is more common in China than previously thought. Conservative management offers good symptom relief, but endovascular treatment shows high success rates for SMA dissection.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Gastroenterology
Background:
- Isolated superior mesenteric artery (SMA) dissection is a rare vascular condition.
- Understanding its prevalence and management in China is crucial.
Purpose of the Study:
- To investigate the status of isolated SMA dissection in China.
- To analyze clinical characteristics, imaging, and treatment outcomes.
Main Methods:
- Systematic review of Chinese-language literature before December 2014.
- Inclusion of all case reports and series.
- Analysis of demographic data, symptoms, diagnosis, and treatment outcomes.
Main Results:
- 622 patients with isolated SMA dissection identified.
- Most common symptom: abdominal pain (91.1%); complication: hypertension (42.7%).
- Conservative treatment (63.2%) showed 62.6% symptom relief; endovascular (33.6%) had 95.2% relief; surgery (3.2%) had 100% relief.
Conclusions:
- Isolated SMA dissection incidence may be underestimated.
- Endovascular treatment is a frequently used first-line approach in China.
- Both conservative and interventional methods demonstrate effectiveness.
