Abstract

A prospective study was instituted to determine both the incidence of postcatheterization arterial thrombus formation and the possibility of a statistically significant correlation between predetermined parameters and the incidence of arterial thrombosis. Pullout angiograms and 12 recorded variables from 176 procedures were studied. Postcatheterization arterial thrombus formation was demonstrated in 9 cases (5%). Statistical analysis by computer showed a statistically significant relationship between 4 factors and postcatheterization thrombosis, viz. catheter/artery ratio, age, catheter diameter, and number of puncture attempts. Total elapsed time of the procedure was not found to be a statistically significant variable. These variables are integrated into a postulate to explain the pathogenesis of postcatheterization thrombus formation seen on pullout angiograms.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
