Background: The purpose of this study was to determine the causes of head and neck free flap loss and to evaluate outcomes after subsequent microvascular and non-microvascular reconstruction.

Methods: Patients who experienced free flap loss between 2000 and 2012 were reviewed.

Results: There were 40 flap losses out of 3090 free flaps (1.3%). Twenty-eight patients underwent subsequent free flap reconstruction of which 27 free flaps were successful (96.4%), which was not significantly different from our initial flap success rate (p = .81). Of patients who underwent subsequent free flap reconstruction for oral/pharyngeal defects, 100% had >80% speech intelligibility and 87.5% were tube feed independent. By comparison, 42.9% of patients who underwent subsequent pectoralis major flap reconstruction had intelligible speech (p = .01) and 25.0% were independent of tube feeds (p = 0.02).

Conclusion: Subsequent free flaps after initial free flap losses can be successful in selected patients. Functional outcomes after subsequent free flap reconstruction are favorable compared to pedicled flap reconstruction.

Introduction: Necrotising soft tissue infection (NSTI) is an exceptionally dangerous infectious disease targeting soft tissues with high mortality as well as morbidity. The aim of reconstructive surgery after initial debridement is to maintain function as well as to achieve a satisfactory cosmetic result.

Presentation Of Case: A 50-year-old male presented with necrotising soft tissue infection on the thorax and left upper arm following mastectomy for breast cancer.

Removal of the rib and adjacent cartilage is a common step for exposure of the recipient chest vessels in free-flap breast reconstructions. However, this adds both short- and long-term morbidity to the procedure. We describe our experience in avoiding rib removal in microvascular breast reconstruction.

: Medial arterial calcification (MAC), a distinct form of vascular pathology frequently coexisting with peripheral arterial disease (PAD), poses unique challenges in limb salvage among patients with diabetes, chronic kidney disease, and end-stage renal disease. This study examines the incidence of MAC and its impact on limb salvage outcomes over a decade of experience at a tertiary limb salvage center. : A retrospective review of all complex lower extremity (LE) reconstructions using local flap (LF) or free tissue transfer (FTT), performed from July 2011 to September 2022, was conducted.

The autologous reconstruction of the female breast using a microsurgical DIEP flap is a reliable and safe method. To detect impairments early and preserve the microvascular flap through timely revision, a better understanding of physiologic perfusion dynamics is necessary. This exploratory study examines changes in microcirculation in free DIEP flaps within the first 72 h after vascular anastomosis using laser Doppler flowmetry and white-light spectrophotometry.
