Complications of catheter angiography. Study with oscillometry and "pullout" angiograms.

TLDR: This study was devised to assess the role of several factors in the production of local arterial thrombosis, including type of catheter, duration of procedure, and oscillometric index of the limb employed.

Abstract: Thrombosis of the punctured vessel has been, in our experience, the most significant complication of catheter angiography. In a preliminary investigation it was noted that a filling defect develops at the puncture site during the course of an arteriographic procedure. This study was devised to assess the role of several factors in the production of local arterial thrombosis. The parameters evaluated were: type of catheter, duration of procedure, and oscillometric index of the limb employed. Methods A Collens Sphygmo-oscillometer was used in the evaluation of each patient prior to angiography. The oscillometric index, which is the greatest excursion of the indicator needle, was recorded at the biceps for axillary studies and at the calf for femoral studies. Oscillometric readings were obtained a second time on the morning following the procedure. Angiography was performed using the Seldinger method of catheterization of the femoral or axillary artery.
