Prognosis
There are few studies of the long-term outcomes of patients treated for MALS. According to Duncan, the largest and more relevant late outcomes data come from a study of 51 patients who underwent open surgical treatment for MALS, 44 of whom were available for long-term follow-up at an average of nine years following therapy. The investigators reported that among patients who underwent celiac artery decompression and revascularization, 75% remained asymptomatic at follow-up. In this study, predictors of favorable outcome included:
- Age from 40 to 60 years
- Lack of psychiatric condition or alcohol use
- Abdominal pain that was worse after meals
- Weight loss greater than 20 lb (9.1 kg)
