From July 1993 through June 1994, the authors performed 42 ultrasound (US)-guided core biopsies with use of a coaxial technique in which a 14- or 15-gauge core biopsy needle was passed through a 12-gauge introducer needle. This technique proved to be effective in all 42 biopsies. Use of the coaxial technique decreased the procedure time necessary for US-guided core biopsy and may be less traumatic than the standard core biopsy technique.

Many patients benefit from the use of tunneled Dacron-cuffed central venous catheters. Operative insertion with the aid of fluoroscopy is required for the proper placement of these devices. Perioperative unintentional removal of the catheter is a reported complication. The outward migration of the device occurs before adequate tissue ingrowth into the Dacron cuff has taken place. The frequency with which this unfavorable outcome occurs can be reduced by placement of a subcutaneous absorbable restraining suture distal to the Dacron cuff during the insertion procedure. The authors advocate the routine use of this adjunctive measure for the insertion of all Dacron-cuffed caval catheters.
