title: Bilateral Persistent Sciatic Artery: Literature Review and Case Report Follow-up for More than Five Years.
abstract: We report a 42-year-old male patient with bilateral persistent sciatic arteries (PSAs), diagnosed by computer tomography angiography for right thigh trauma and follow-up for more than 5 years. A review of 61 bilateral PSA patients reported in the international literature was performed. There was no gender predilection (male versus female: 46% vs. 54%). The same type of PSA in both sides was 74%. The complete PSA type was 77% in the right side and 75% in the left side. Symptomatic bilateral PSA was 72%, including aneurysm in 57% (combined with ischemia or embolism 39%), and the mean age was 61 ± 12 years. The asymptomatic bilateral PSA was 13%, and the mean age was 27 ± 8 years. Most asymptomatic PSAs were diagnosed by arteriography with demonstration of the proximal vessels, such as during embolization of the uterine arteries. One case experienced the loss of a limb to inadvertent embolization of PSA. The presented patient was treated with debridement and lifestyle modification to avoid repetitive PSA compression, and was followed up for more than 5 years without complications. The characteristics are no different between bilateral and unilateral PSAs. PSA complications may be avoided if we can prevent the acquired factors. We should pay attention to PSA in our clinical work to avoid severe complications.
