Experimental Studies on Peripheral Circulation and Heart with Closed Arteriovenous Fistula

Abstract

Femoral arteriovenous fistula (AVF) was performed and closed after a month in the dogs.
Follow up studies were carried out on blood flow, blood pressure, angiogram, diameter of blood vessel and cardio-thoracic rate (CTR).
The results obtained were mainly as follows:
1. Increased blood flow of femoral artery decreased considerably and blood pressure increased after closure of AVF.
2. Dilated proximal femoral artery recovered during three or four weeks after closure of AVF.
3. Increased CTR recovered within four weeks after closure of AVF.
4. Increased collateral vessels decreased after closure of AVF.
