However, no clear standard is available for evaluating angiographic results to predict free-flap survival outcomes. We developed angiographic criteria for predicting surgical outcome in patients with lower-extremity peripheral arterial disease based on abnormality of the anterior tibial and posterior tibial arteries. We applied the criteria to a small number of patients scheduled for microsurgical reconstruction of the lower leg. Angiographies with arterial abnormalities were classified into 3 groups: favorable free-flap survival, compromised free-flap survival, and postsurgical pedal ischemia. The study enrolled 50 patients between 2005 and 2013. In 42% of patients, arterial abnormalities were observed by angiography. Age &gt;65 years was the strongest risk factor for development of lower-leg arterial abnormality ( P &lt; .001). The anterior tibial and peroneal arteries were significantly more stenotic than other vessels. In the favorable free-flap survival and compromised free-flap survival groups, free-flap transfers were attempted in 7 patients but intraoperatively abandoned in 2 patients, with postoperative failure in 1 patient. In the postsurgical pedal ischemia group, free-flap transfers were attempted in 10 patients but intraoperatively abandoned in 6 patients, with postoperative failure in 3.<\/jats:p>","DOI":"10.1177\/1534734616668764","type":"journal-article","created":{"date-parts":[[2016,9,30]],"date-time":"2016-09-30T20:08:38Z","timestamp":1475266118000},"page":"325-331","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["Preoperative
