Background: Vascular patency is the key element for high flap survival rates. The purpose of this study was to assess and compare the blood flow characteristics of deep inferior epigastric perforator (DIEP) and muscle-sparing transverse rec…

Rapid identification of possible vascular compromise in free flap reconstruction to minimize time to reoperation improves achieving free flap salvage. Subjective clinical assessment, often complemented with handheld Doppler, is the golden s…

Soft tissue defect coverage has always been a challenge for the orthopaedic surgeon. Over the last decades the surgery of flaps has completely changed the prognosis for large defects. The purpose of this study is to retrospectively review o…

[BACKGROUND] With severe vascular calcifications, vascular clamp application and utilizing the vessel for free flap recipient vessel becomes impossible. These obstacles can be overcome with the Fogarty catheter and vein graft. [PATIENTS AN…

[PURPOSE OF REVIEW] To highlight three clinical arenas in which head and neck free-flap compromise is encountered and acted upon: nonoperative, operative and postoperative realms. [RECENT FINDINGS] Time to identification and intervention i…

[BACKGROUND] We aim to define a set of terms for common free flap complications with evidence-based descriptions. [METHODS] Clinical consensus surveys were conducted among a panel of head and neck/reconstructive surgeons (N = 11). A conten…

This study was conducted to evaluate the outcomes of re-exploration procedures done after head and neck microvascular flap reconstructions. This is a retrospective review of 109 flaps in 106 patients (three patients had two flaps each) that…

[BACKGROUND]  Many microsurgeons fear high complication rates and free flap loss when vein grafting is necessary to restore blood flow at the recipient site. The aims of this study were to comparatively analyze surgical outcomes of interpos…

We reported a proof-of-concept study of developing an electrochemical biosensor for prolonged continuous monitoring free flap failure caused by vascular occlusion after reconstructive surgery. Ferrocene (Fc)-containing Chitosan-cografted-Br…

[BACKGROUND] Although the profunda artery perforator flap has gained popularity in breast reconstruction, it has not been well described for reconstruction of head and neck defects. The authors report their experience with free profunda art…

Micro-vascular flaps have been used for the repair of challenging defects for over 45 years. The risk of failure is reported to be around 5-10% which despite medical and technical advances in recent years remains essentially unchanged. Prec…

[BACKGROUND] Microvascular tissue transfer is a common reconstructive procedure. We designed a bioelectrical impedance assessment (BIA) system for quantitative analysis of tissue status. This study attempts to verify it through the animal m…

[BACKGROUND] The majority of hindquarter amputation defects can be reconstructed with local anterior or posterior thigh flaps. Less than 5% of soft tissue defects require free flap reconstruction after tumour resection. Lower extremity fill…

[OBJECTIVES] Free flap surgery is an essential procedure in soft tissue reconstruction. Complications due to vascular compromise often require revision surgery or flap removal. We present hyperspectral imaging (HSI) as a new tool in flap mo…

Free flap reconstruction is a common procedure with success rates greater than 99%. However, vascular complications may occur, resulting in flap failure. For this reason, early detection of vascular compromise is crucial for flap salvage. V…

[BACKGROUND] The aim of this study was to report the first case of acute facial allograft transplantation (facial allograft transplantation) failure with allograft removal and autologous free-flap reconstruction. [METHODS] A 49-year-old fe…

[BACKGROUND] Even though the benefit of free tissue transfer is uncontested in complex reconstructive cases, vascular compromise and/or flap failure remain a challenge for the surgeon and identification of possible risk factors can aid in t…

[BACKGROUND] Clinical examination remains the cornerstone for postoperative monitoring of free flaps but is highly dependent on the surgeon's ability and experience. Duplex echography provides a noninvasive objective evaluation of tissue pe…

Advances in free flap reconstruction of complex head and neck defects have allowed for improved outcomes in the management of head and neck cancer. Technical refinements have decreased flap loss rate to less than 4%. However, the potential …

Management of pediatric iatrogenic arterial occlusions can be challenging clinically, leading to chronic complications such as claudication and limb length discrepancy. We report the case of a 6-month-old female patient who had experienced …
