ABSTRACT

Background: The prevalence and treatment of peripheral arterial disease in the Caribbean is not well documented. The aim of this study was to review the results from a small hospital in the Caribbean.

Methods: One-hundred and eight infra-inguinal arterial reconstructions on 90 patients were retrospectively reviewed. Patients were classified according to the categories suggested by the Ad Hoc Committee on Reporting Standards of the Joint Councils of the Society for Vascular Surgery. Follow-up ranged from 0 to 103.1 months. The Kaplan-Meier method was used to visualize survival, limb salvage rates and primary and secondary patency rates. Cox regressions were used to identify potential risk factors.

Results: The limb salvage rates were 74.5% after one year and 71.4% after five years. Overall primary patency rates were 67.0 % after one year, 63.4% after three years and 50.8 % after five years. Overall secondary patency rates were 86.4% after one year and 75.1% after five years. The primary patency rate for autologous saphenous vein was 82.4% (SE 7.5%) after five years. The primary patency rates for prosthetic grafts were 62.1% (SE 8.5%) after one year, 56.9% (SE 9.2%) at three years and 37.9% (SE 16.7%) after five years.

Conclusion: Infra-inguinal arterial bypass surgery is feasible in small Caribbean hospitals showing results comparable to major studies.
