Drug abuse may affect lower extremity vessels due to ischemia following intra-arterial injections, vasospasm, arterial and venous pseudoaneurysms, arteriovenous fistulae, vasculitis and complicated abscesses. Little is known about the outcomes of Lower Extremity Bypass (LEB) for peripheral arteries disease (PAD) in patients with a history of drug abuse disorder. The aim of this study is to evaluate the outcomes of LEB in this patient population.

METHODS:

A retrospective study of the Premier Healthcare Database 2009-2015 was performed. In-hospital complications, mortality and hospitalization costs were assessed in patients with a history of drug abuse disorder (opioids, cannabis, cocaine, sedatives/hypnotics/anxiolytics and hallucinogens/methamphetamine/psychoactive drugs) who underwent LEB for PAD. Multivariable logistic and Generalized Linear Models were utilized to study the association between drug use/misuse and in-hospital outcomes after LEB.

RESULTS:

Our cohort included 50,976 patients, of which 967 (2%) had a history of drug abuse disorder on admission. The majority of drugs were cannabis (38.5%), followed by opioids (21.5%) and cocaine (14.5%). Patients with a history of drug use/misuse were significantly at a higher risk of developing complications during their hospital stay (71.9% vs 64.2%, POriginal article
