Introduction: Arterial embolism unrelated to peripheral vascular disease (AEUPAD) is known to be associated with risk factors such as malignancy, atrial fibrillation and thrombophilias. This study aimed to determine survival following embolecotmy of native arteries for AEUPAD. Methodology: Retrospective analysis was performed of a prospectively maintained database in a single vascular centre for the past 18 years, for all native artery embolectomies. Patients with PAD and graft embolectomies were excluded. Kaplan-Meier survival analysis was performed to calculate overall survival. Relationship between death and known risk factors were also assessed. Results: From 1994 to 2012, 192 patients had 204 native artery embolectomies for AEUPAD. 11 had multiple embolectomies. 100(49%) were male, mean age 72.5 (range: 9-102) years. Embolectomies performed; femoral 115 (56%), popliteal 47(23%), brachial 40 (17%), iliofemoral 1(0.4 %) and tibial 2(0.8%). 80 (41.60%) of patients were alive at the time of analysis. Kaplan-Meier estimates 69.77% survival 12 months post embolecotmy, decreased to 46.42% and 18.61% within 2 and 5 years respectively. Age (p<0.0001) and male sex (p=0.0451) were associated with death. Smoking had a negative correlation with mortality (p=0.0080). Conclusions: There is high mortality following embolecotmy. Though basic investigations are performed, further assessment may be necessary to prevent high mortality.
