Inadvertent placement of a Kimray-Greenfield filter into the right side of the heart occurred in the operating room. With the use of intraoperative fluoroscopy while the patient remained under general anesthesia, the filter was extracted and successfully placed in the inferior vena cava. This was accomplished with standard percutaneous catheter techniques from the femoral route.

Arteriovenous malformations (AVM) are rare vascular lesions that can present with a myriad of clinical presentations. In our institutions, initial workup consists of a clinical exam, color Doppler imaging, and magnetic resonance imaging. After the initial noninvasive workup, arteriography, at times closed system venography, and ethanol endovascular repair of the AVM is performed under general anesthesia. Depending on the size of the lesion, additional Swan-Ganz line and arterial line monitoring are performed. Patients are usually observed overnight and uneventfully discharged the following day if no complication occurs. Patients are followed at periodic intervals despite cure of their lesion. Long-term follow-up is essential in AVM management.
The Bard prostate biopsy gun under ultrasonic guidance provides consistent, high quality prostatic core samples for histopathologic diagnosis. This device can be adapted for biopsy of abdominal organs using computed tomographic guidance. We demonstrate how these technical modifications can be made. Having used this modified device in conjunction with the 18-gauge prostate biopsy needle in 25 patients, we have had excellent results and no complications.
