Key result
Vein valve transplantation yielded excellent results in 75% of patients, while venous bypass for obstructive lesions was associated with a high incidence of thrombosis.
Why the study?
Does venous reconstruction improve outcomes in patients with venous insufficiency?
Observational (n=160)
Does venous reconstruction improve outcomes in patients with venous insufficiency?
Vein valve transplantation shows good results for venous insufficiency, but venous bypass requires a temporary arteriovenous fistula and long-term anticoagulation to prevent thrombosis.
Cautions against venous bypass without adjuncts; leaves open durability of valve transplantation in prospective cohorts.
Since 1980 the authors have oper ated on 160 patients with venous in sufficiency. Surgical results of vein valve transplantation have been grat ifying with 75% having excellent re sults. Venous bypass for obstructive lesions have been associated with a high incidence of thrombosis. It is ap parent that a temporary arteriove nous fistula followed by long-term anticoagulant is necessary to achieve satisfactory results from autogenous vein bypass.

Taheri et al. (1989) conducted an observational in venous insufficiency (n=160). Vein valve transplantation and venous bypass was evaluated on excellent results (for vein valve transplantation). Vein valve transplantation yielded excellent results in 75% of patients, while venous bypass for obstructive lesions was associated with a high incidence of thrombosis.
