A-V fistula after venous reconstruction. A simplified method of producing and obliterating the shunt.
To improve patency of the low flow, low pressure crossover venous graft for unilateral iliac venous occlusions, complementary arteriovenous fistula has been effective. Two additional anastomoses are usually required to construct a complementary A-V fistula, and a sometimes difficult and potentially dangerous dissection may be required to take down the fistula. A technique has been developed for producing an A-V fistula with only one additional anastomosis. This fistula can be obliterated later by tightening a previously placed loop left in a subcutaneous position. This technique has been used successfully in two patients.
