NONSURGICAL TREATMENT OF POSTCATHETERIZATION FEMORAL ARTERY OCCLUSION— A NEW TECHNIQUE

CLINTON SNYDER M.D. and KURT AMPLATZ M.D.

Arteriotomy has been the treatment of choice in arterial occlusion which occurs in approximately 1 per cent of cases of femoral artery catheterization. However, recent experimentation in femoral artery occlusion in dogs has demonstrated that thrombi can be successfully removed percutaneously.

A large bore teflon sheath which approximates vessel size is passed into the artery oven a catheter which is placed distal to the site of arterial obstruction. The clot is expelled spontaneously by the blood stream or extracted with a Fogarty balloon catheter passed through the sheath.

Blood flow has been restored in 6 animals using this method.

Successful clot removal has been performed in 1 human case. Further human studies are presently planned for retrieval of thrombi associated with percutaneous catheterization.
