Lumbar sympathectomy and distal arteriovenous fistula as adjuncts to prevent arterial rethrombosis after thrombectomy: experimental study in dogs.

摘要: The role of lumbar sympathectomy and distal arteriovenous fistula (AVF) in preventing rethrombosis femoral arteries with intimal injury poor run-off was studied 21 dogs. Femoral artery thrombosis induced by endothelial lesion all animals (phase 1) 24 hours later the arterial flow restored thrombectomy. dogs were then randomly allocated into 3 experimental groups: control, sympathectomy, AVF 2). Critical stenosis popliteal created a partially occluding ligature order to simulate run-off. After for presence 3). At end phase 2 during 3, pressure flow, fluorescein circulation time paw temperature measured, arteriography done. Arterial significantly prevented group (6/7) when compared control (2/7) or (1/7). These data suggest an effective action adjuvant AVF, but not after thrombectomy
