BACKGROUND: The retroauricular tissues have been used for a long time for ear reconstruction, but the anatomical bases of flaps of this region are not completely clear. The aim of this study was to estimate blood supply area and location of this on the skin and fascia retroauricular dependent of posterior auricular artery (PAA) to establish safe margins to design flaps for auricular reconstruction. METHODS: Dissection under magnification (×3.5) of the PAA through a cervical approach; injection of methylmethacrylate in the PAA as a staining technique; retroauricular approach to identify the territory of irrigation of PAA in the retroauricular skin and fascia; measuring and location of the stained area; and report of 2 cases of ear reconstruction with fasciocutaneous and fascia flaps based on PAA, designed according to the anatomical study...

INTRODUCTION: Reconstruction has evolved long way from primary closure to flaps. As time evolved, better understanding of vascularity of flap has led to the development of innovative reconstructive techniques. These flaps can be raised from various parts of the body for reconstruction and have shown least donor site morbidity. We use one such peroneal artery perforator flap for tongue reconstruction with advantage of thin pliable flap, minimal donor site morbidity and hidden scar. MATERIALS AND METHODS: Our patient 57yrs old lady underwent wide local excision with selective neck dissection...

Prevention of serious diabetic foot complication like ulceration or infection is an important issue. As the development of thermal graphic technologies, foot temperature-guided avoidance therapy has been recommended. Doctors from Hospital National Dos de Mayo are studying on the risk of the diabetic foot passing from Grade 0 to Grade 1 in the Wagner Scale. This risk to develop ulcers is related to the temperature difference of corresponding area between left and right foot. Generally speaking, the diabetic foot with greater mean temperature difference has more potential to develop ulcers; especially, area whose temperature difference of more than 2...

The goals of treatment for critical limb ischemia (CLI) are alleviation of ischemic rest pain, healing of arterial insufficiency ulcers, and improving quality of life, thereby preventing limb loss and CLI-related mortality. Arterial revascularization is the foundation of a contemporary approach to promote amputation-free survival. Angiosome-directed revascularization has become a popular theory of reperfusion, whereby anatomically directed arterial flow is restored straight to the wound bed. Innovations in endovascular revascularization combined with a multidisciplinary strategy of wound care accelerate progress in CLI management...

BACKGROUND: A long period is generally required for ischemic ulcer to heal after revascularization. The strategy of postoperative wound care can affect wound healing. This study was conducted to investigate the degree to which aggressive wound care (AWC) by a team of multidisciplinary specialists actually shortens the time to wound healing and increases the rate of wound healing in limbs undergoing surgical bypass for ischemic tissue loss in a real clinical setting. METHODS: A total of consecutive 126 patients undergoing infrainguinal bypass for tissue loss from April 2011 to March 2015 were reviewed...

INTRODUCTION: This study aimed to evaluate the impact of angiosome targeted (direct) revascularisation according to revascularisation method in patients with diabetes. MATERIALS AND METHODS: This retrospective study cohort comprised 545 diabetic patients with critical limb ischaemia and tissue loss (Rutherford 5, 6). All patients underwent infrapopliteal endovascular (PTA) or open surgical revascularisation between January 2008 and December 2013. Differences in the outcome after direct revascularisation, bypass surgery, and PTA were investigated by means of Cox proportional hazards analysis...

INTRODUCTION: Infra-popliteal angioplasty continues to be widely performed with minimal evidence to guide practice. Endovascular device selection is contentious and there is even uncertainty over which artery to treat for optimum reperfusion. Direct reperfusion (DR) targets the artery supplying the ischaemic tissue. Indirect reperfusion (IR) targets an artery supplying collaterals to the ischaemic area. Our unit practice for the last eight years has been to attempt to open all tibial arteries at the time of angioplasty...

Background The science and technical acumen in the field of vascularized composite allotransplantation has progressed rapidly over the past 15 years, and transplantation of specialized units of the face, such as the nose, appears possible. No study to date has evaluated the technical feasibility of isolated nasal unit transplantation (NUT). In this study, we explore the anatomy and technical specifics of NUT. Methods In this study, four fresh cadaver heads were studied. Bilateral vascular pedicle dissections were performed in each cadaver...

Percutaneous therapies for peripheral artery disease continue to evolve with new techniques and devices. Although guidelines-recommended therapies have impacted cardiovascular morbidity and mortality, endovascular interventions have been shown to reduce limb pain, improve quality of life, and prolong walking distance for those with claudication and to reduce amputation rates among those with critical limb ischemia. Novel devices such as drug-eluting stents and drug-coated balloons have improved patency for moderate-length lesions, whereas others allow treatment of heavily calcified and tortuous segments...

The centre ground in the world of flaps have over time, gradually shifted from tubed pedicled, random-pattern, axial-pattern, pedicled, free and currently, to free-styled flaps. These concepts are broadly based on the angiosome-perforasome concept. In this case report, we illustrate how the concept of venosome capture can be transposed onto reverse-flow flaps with the aid of venous supercharging. Moreover, if this is seen from the free-styled flap perspective, it requires supermicrosurgical expertise. This case report hence, serves as a fusion of all the above concepts...

OBJECTIVE: In recent years, a controversial discussion about the clinical relevance of the angiosome concept during tibial angioplasty has developed. Therefore, we conducted a prospective study to evaluate the angiosome concept on the level of microcirculation during tibial vascular interventions. METHODS: Thirty patients with isolated tibial angioplasty were examined prospectively. Macrocirculation was evaluated by measurement of the ankle-brachial index (ABI)...

BACKGROUND: The definition of angiosome-targeted revascularization is confusing, especially when a tissue lesion affects several angiosomes. Two different definitions of direct revascularization exist in the literature. The study aim was (1) to compare the 2 definitions of direct revascularization in patients with foot lesions involving more than one angiosome and (2) to evaluate which definition better predicts clinical outcome. METHODS: This study cohort comprises 658 patients with Rutherford 5-6 foot lesions who underwent infrapopliteal endovascular or surgical revascularization between January 2010 and July 2013...

BACKGROUND: Major vessels in the diabetic foot are often calcified and inadequate for use as recipient vessels. Thus, a supermicrosurgery technique using small branches or perforators from other collateral vessels with an adequate pulse may be an alternative method. This study evaluated outcome using the supermicrosurgery concept and the risk factors involved. METHODS: Ninety-five cases of diabetic foot reconstruction were reviewed; the average patient age was 57 years; average follow-up was 43...

BACKGROUND: Fasciocutaneous flaps supplied by discrete perforator arteries can be raised in numerous parts of the human body and are routinely used in plastic surgery. The aim of this anatomical investigation was to provide a description of the vascular supply of the medial upper arm, to localize and measure the perforator arteries and to define potential perforator flap dimensions in pendency of individual anatomical conditions. MATERIAL AND METHODS: A total of 20 upper limbs from 11 fresh cadavers were examined...

One third of patients with critical limb ischemia (CLI) has below the knee lesions and requires a restoration of direct blood flow into the foot. However, many of these patients are ineligible for open surgery. The primary goals thus become pain relief and limb salvage over patency. The angiosome concept helps determine the target artery to treat in priority. The endovascular approach has decreased morbidity and mortality rates compared to distal bypass surgery; while subintimal retrograde, trans-collateral and loop techniques push the limits of open surgery by reopening the plantar arch, thereby improving run-off...

Background The best known limitation to the use of prefabricated flaps is their limited survival area. One explanation for this is insufficient neovascularization. However, blood flow of prefabricated flaps is through their innate vascular network. This could lead one to conclude that angiosomes may impede blood perfusion. This study aims to settle this contradiction between theory and clinical practice. Methods We performed a two-stage operation of a prefabricated abdominal flap in a rat model. The rats were divided into five groups (n = 6/group)...
