Fluoroscopically guided Norplant removal.

The Norplant contraceptive implant system is a commonly used method of contraception worldwide. Implant placement and removal are usually simple office-based outpatient procedures. Norplant removal can occasionally become difficult, usually secondary to improper insertion. In these instances, we describe a method of Norplant removal that can easily be performed with use of high-resolution fluoroscopy with associated digital subtraction imaging.

Peripheral transcatheter embolization with platinum microcoils.

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.
