Key result
Tracker-18 microcoil embolotherapy yields ~94% clinical success after standard catheterization fails.
Why the study?
Peripheral superselective catheterization with standard angiographic catheters is not always possible for embolotherapy, requiring alternative methods.
Does embolotherapy with platinum microcoils delivered through a microcatheter achieve vascular occlusion and clinical success in patients where standard catheterization is not possible?
Observational (n=16)
Does embolotherapy with platinum microcoils delivered through a microcatheter achieve vascular occlusion and clinical success in patients where standard catheterization is not possible?
Embolization with platinum microcoils through a microcatheter is a safe and effective alternative when standard methods of peripheral embolization are not possible.

Supports microcatheter coil embolization as bailout when standard access fails; hypothesis-generating and requires prospective validation.
Embolotherapy with platinum microcoils delivered through the Tracker-18 microcatheter (Target Therapeutics, San Jose, Calif) was performed in 16 patients when peripheral superselective catheterization with standard angiographic catheters was not possible. The Tracker-18 catheter could be directed distally into small peripheral vessels for delivery of the microcoils. These microcoils, with attached fiber strands, resulted in vascular occlusion within a few minutes in all cases. Embolotherapy was technically successful in all patients. The procedures were clinically successful in 15 of 16 patients (94%), and no complications were encountered. Embolization with platinum microcoils through the Tracker-18 catheter is useful when standard methods of embolization are not possible.

Kaufman et al. (1992) conducted an observational in Peripheral vascular conditions requiring embolization (n=16). Embolotherapy with platinum microcoils via Tracker-18 microcatheter was evaluated on Clinical success. Embolotherapy with platinum microcoils via the Tracker-18 microcatheter achieved clinical success in 94% (15 of 16) of patients when standard catheterization failed, with no complications.
