Transcatheter vessel occlusion: angiographic results versus clinical success.
A review was made of 219 transcatheter vessel occlusion procedures performed over a ten-year period for control of hemorrhage, tumor palliation, or blood supply redistribution prior to intra-arterial chemotherapy. Complete angiographic success was obtained in 85% of the procedures, with partial success in 8%; complete clinical success was achieved in 53% of patients, with partial success in 23%. The most satisfactory clinical results were obtained with hemorrhagic gastritis and pelvic trauma. Embolizations for duodenal ulcer hemorrhage and transhepatic variceal occlusion were the least clinically successful, although isobutyl-cyanoacrylate appeared to be a significant improvement in angiographic therapy for duodenal ulcer. The overall complication rate was 13%, with one third of the complications clinically silent. These results indicate that transcatheter vessel occlusion is a relatively safe and effective method for control of hemorrhage or tumor infarction.
