Complications of percutaneous transaxillary catheterization for arteriography and selective chemotherapy.

This report enumerates and analyzes the complications of percutaneous transaxillary catheterization encountered in 200 consecutive patients undergoing diagnostic arteriography, and 20 consecutive patients who had catheter placement for selective chemotherapy. Diagnostic arteriography led to minor complications in eleven percent and major complications in two percent. Risk correlated with the type of procedure, number of catheter exchanges and particularly, the presence of arteriographic risk factors, such as hypertension, bleeding tendencies, and advanced atherosclerosis. Therapeutic catheter placements had a 15 percent incidence of minor and a 20 percent incidence of major complications. Here, also, complications were more likely in the presence of the arteriographic risk factors. Suggested means for decreasing the hazards of the transaxillary catheterization include: exclusion of high risk patients, use of a proper puncture site, careful catheter manipulation, the fewest possible catheter exchanges, correct manual hemostatis following catheter withdrawal, and close observation of the patient after the procedure. Early surgical intervention is indicated in the presence of a progressively developing neural defect.
