INTRODUCTION: Successful outcome of any vascularised free flap basically depends upon the successful restoration of circulation in the flap after anastomosis. As the flap ischemic time is the significant factor which determines the outcome of any free flaps, due consideration is given to reduce the time for anastomosis for reperfusion. The present study compares and evaluates whether the usage of microvascular couplers with the conventional suturing reduce the ischemic time of the free flaps...

BACKGROUND: Breast reconstruction with microvascular free tissue transfer has become a widely used method. Despite a high rate of success, a compromised flap necessitating re-exploration can occur. Here, we introduce direct thrombectomy as a flap salvage technique, and compared the results with conventional thrombectomy. METHODS: A total of 488 patients who underwent breast reconstruction using a free transverse rectus abdominis myocutaneous flap between March 2009 and February 2014 were retrospectively analyzed...

OBJECTIVE: Microsurgical techniques are increasingly used in routine surgical practice as well as in biomedical research. The training opportunities at standardised training courses are limited, and no microsurgical training facility or programme existed in Scandinavia before 2013. METHODS: A microsurgery laboratory was set up and two different courses were started, aiming separately at biomedical researchers and surgeons. The course for biomedical researchers teaches basic microsurgical skills such as vessel isolation, cannulation, and arterial microvascular suture under magnification...

Three-dimensional (3D) high definition (HD) video systems are changing microsurgical practice by providing stereoscopic imaging not only for the surgeon and first assistant using the binocular microscope, but also for others involved in the surgery. The purpose of this study was to evaluate the potential to replace the binocular microscope for microarterial anastomoses and assess the rate of learning based on surgeons' experience. Two experienced and two novice microsurgeons performed a total of 88 rat femoral arterial anastomoses: 44 using a 3D HD video device ('Trenion', Carl Zeiss Meditech) and 44, a binocular microscope...

We describe our experience of cervical lymphadenectomy with microvascular anastomoses involving levels I to V through a minimally-invasive neck dissection. We retrospectively studied 12 patients who had levels I to IV neck dissection with free flap reconstruction between July 2013 and April 2015 at Poole Hospital (male:female ratio 8:4, mean (range) age 66 (49 - 83) years). The mean (range) operating time was 7 (5 - 8) hours, and the total volume drained from the neck was 105 (60-300) ml. The mean (range) number of harvested lymph nodes was 26 (13-39) from levels I to III, and 33 (20-42) from levels I to IV...

INTRODUCTION: Fibrin sealants have had applications in hemostasis, cohesion, and promotion of healing in plastic surgery. In this article, we review cases where fibrin sealant was used to stabilize microvascular pedicles and compared with previous free flaps performed without fibrin sealant. METHODS: Between 2008 and 2010, 62 consecutive patients underwent free tissue transfer for reconstruction; this involved 33 latissimus dorsi perforator flaps, 14 thoracodorsal artery perforator flaps, 9 latissimus dorsi myocutaneous flaps, 3 lateral thoracic artery perforator flaps, and 3 transverse rectus abdominis myocutaneous flaps, used in head and neck reconstruction, lower limb reconstructions, breast reconstructions, and facial palsy reconstruction...

Background Atherosclerosis is a known risk factor for flap loss in microsurgery. Several microsurgical techniques, like plaque removal, have been proposed for atherosclerotic vessels, but these techniques often induce intimal injuries. The aim of this study was to investigate the impact of various endothelial defects on the risk of thrombosis in a rat acute intimal injury model. Methods Endothelial defects of various forms and sizes were created in the abdominal aorta of 30 male Wistar rats following a strict protocol...

BACKGROUND: Free muscle transfer is an important in dynamic facial reanimation; however, suitable donor vessels in this population can be inadequate. In this case series, the submental vessels were used as donors to free gracilis muscle in vessel-depleted patients. METHODS: Five patients underwent free gracilis muscle transfer for smile reanimation, 2 with a prior failed free gracilis transfer, 2 with vascular anomalies, and 1 with previous distal ligation of the facial vessels...

Objectives: Free flaps are widely used to reconstruct head and neck defects. Despite the improvement in the surgical techniques and the surgeons' experiences, flap failures still occur due to thrombotic occlusion after small vessels anastomosis. To reduce the possibility of flap loss as a result of thrombotic occlusion, various anticoagulants have been used. In this study we decided to evaluate a new protocol for anticoagulation therapy and its effect on flap survival and complications...

Background Patients are usually advised not to consume caffeine following digital replantation. This study examined the effect of caffeine on blood flow distal to the site of anastomosis in the femoral arteries of rats. Methods A total of 28 Sprague-Dawley rats were used for this study. The femoral arteries were exposed bilaterally and baseline blood volume flow measurements were taken on intact arteries using a transit time flow-meter probe. All rats underwent transection and microvascular anastomosis of the femoral artery on the right side while the left side remained intact to serve as a control...

BACKGROUND: Losing the ability to speak severely affects the quality of life, and patients who have undergone laryngectomy tend to become depressed, which may lead to social withdrawal. Recently, with advancements in chemoradiotherapy and with alternative perspectives on postoperative quality of life, larynx preservation has been pursued; however, the selection of candidates and the optimal reconstructive procedure remain controversial. In this study, we retrospectively reviewed our experience with free jejunal graft for larynx-preserving cervical esophagectomy (LPCE), focusing on microvascular reconstruction...

Acute cortical necrosis and hemolytic uremic syndrome (HUS) are 2 clinical scenarios of parenchymal acute kidney injury (AKI) related to renal microvascular injury. Acute cortical necrosis is a rare condition related to an ischemic necrosis of renal cortex. Necrotic lesions can be due to several injuries and may be focal, multifocal or diffuse. Renal necrotic lesions become visible with ultrasound only after renal recovery. HUS is a rare disease characterized by hemolytic anemia, thrombocytopenia and AKI. Color Doppler ultrasound is useful during diagnostic and follow-up phase...

OBJECTIVE: One of the most common encountered problems in free flap surgeries is anastomotic thrombosis. The mean platelet volume (MPV) may indicate the concentration of intra-platelet proactive substances and the thrombogenic potential of the platelets. MPV is used as a clinical monitoring index in routine blood counts, it has not yet been effectively used in free flap surgery. METHODS: This study evaluates the relationship between the preoperative MPV value and anastomotic thrombus formation during the postoperative 48 hours in 32 free flap operations from September 2013 to September 2014...
