Monitoring buried free flaps: limitations of the implantable Doppler and use of color duplex sonography as a confirmatory test.

Background: Postoperative monitoring of free flaps is important to minimize the risk of flap failure, but monitoring buried free flaps is difficult because the standard methods of clinical examination and surface Doppler monitoring are not possible. Buried free flaps are often monitored using an implantable 20-MHz ultrasonic Doppler probe.

Methods: The authors conducted a retrospective clinical study of buried free flaps to assess the reliability of the implantable Doppler probe in postoperative monitoring of free flaps.

Bilateral anterolateral thigh flaps for large-volume breast reconstruction.

Autologous tissue reconstruction of a large breast in patients who are not candidates for a TRAM flap is a difficult problem. We present a case report of the use of bilateral free anterolateral thigh (ALT) flaps for immediate reconstruction of a unilateral large breast in a patient who had a previous abdominoplasty. Use of ALT flaps allows two or three surgical teams to work simultaneously, does not require intraoperative patient repositioning, has minimal donor-site morbidity, and can provide ample malleable soft tissue for breast reconstruction.

Bioglass attenuates a proinflammatory response in mouse peritoneal endotoxicosis.

Bioglass is a bioactive, resorbable ceramic particle that was developed to assure binding to living tissues. Bioglass is currently employed to fill osseus defects in oral surgery, and it possesses both unique anti-inflammatory and antimicrobial properties. In an effort to determine whether Bioglass may be useful as an adjunct anti-inflammatory device in local inflammatory processes, we examined whether exposure of the peritoneal cavity to Bioglass would induce a pro- or anti-inflammatory response, and then modulate a subsequent proinflammatory response to endotoxin.
