Key result
Benzalkonium-heparin-coated catheters used in 563 patients undergoing angiographic procedures resulted in 0% thromboembolic complications.

Do Benzalkonium-heparin-coated angiographic catheters prevent thromboembolic complications in patients undergoing angiographic procedures?
Benzalkonium-heparin-coated catheters appear safe and may reduce angiographically-related thromboembolism without increasing puncture site hematomas.
May support coated catheter safety without excess bleeding; hypothesis-generating for thromboembolism prevention, requiring randomized confirmation.
Benzalkonium-heparin-coated catheters were used in 563 patients undergoing visceral, cardiothoracic, and neuroangiographic procedures. No thromboembolic complications occurred. Equivocal clot formation was observed at “pullout” arteriography in 4 of 100 cases. Hematoma formation at the arterial puncture site was not a problem. It is suggested that heparin-coated catheters are a safe and simple means of reducing the incidence of angiographically-related thromboembolism.

Hawkins et al. (1973) conducted an observational in Patients undergoing visceral, cardiothoracic, and neuroangiographic procedures (n=563). Benzalkonium-heparin-coated catheters was evaluated on Thromboembolic complications. Benzalkonium-heparin-coated catheters used in 563 patients undergoing angiographic procedures resulted in 0% thromboembolic complications.
