There is evidence that nerve flaps are superior to nerve grafts for bridging long nerve defects. Moreover, arterialized neurovenous flaps (ANVFs) have multiple potential advantages over traditional nerve flaps in this context. This paper describes a case of reconstruction of a long defect of the ulnar artery and nerve with an arterialized neurovenous free flap and presents a literature review on this subject. A 16-year-old boy sustained a stab wound injury to the medial aspect of the distal third of his right forearm...

Successful total scalp replantation was performed in our case. Based on the angiosome concept and anatomical study, the avulsed scalp survived with unilateral anastomosis of the superficial temporal artery and superficial temporal vein, largely due to the presence of rich arterial and venous arcades in the scalp. The patient currently has no problems with activities of daily living, although total hypoaesthesia and dysfunction of the left frontal muscle of the forehead are present. In addition, the combined findings of hair growth pattern indicated the vascular territories of the scalp skin...

Plastic and reconstructive surgery relies on the knowledge of angiosomes in the raising of microsurgical flaps. Growing interest in muscle-sparing perforator flaps calls for reliable methods to assess the clinical feasibility of new donor sites in anatomical studies. Several injection techniques are known for the evaluation of vascular territories. Indocyanine green-based fluorescence angiography has found wide application in the clinical assessment of tissue perfusion. In this article, the use of indocyanine green-based fluorescence angiography for the assessment of perforasomes in anatomical studies is described for the first time...

An angiosome is a three dimensional volume of biological tissue which a specific artery governs. Although proven useful for vascular surgery, the direct relationship between arterial flow and microcirculation in specific angiosome remains controversial. Here, we present new optical approach, a four-channel diffuse speckle contrast analysis (DSCA) which can simultaneously measure blood perfusion at different foot area. Based on the hypothesis that same angiosome will support similar low frequency oscillation, we investigated cross-correlation among different DSCA channels...

BACKGROUND: The angiosome is a three-dimensional block of tissue supplied by a source vessel with its boundary outlined either by an anastomotic perimeter of reduced-caliber choke vessels or by true anastomoses with no reduction of vessel caliber. This article focuses on the role of these anastomotic vessels in defining flap survival or the necrotic pattern seen in fulminating meningococcal septicemia. METHODS: Experiments in pigs, dogs, guinea pigs, and rabbits over the past 46 years were reviewed, focusing on the necrosis line of flaps, the effects of various toxins in vivo, and correlating these results in the clinical setting...

Background: Thermoregulation is a complex autonomic process to keep or to dissipate heat in the human body. Methods: In this work, by means of the thermogram of the plantar skin, the thermoregulation of healthy individuals, overweight-obese, and diabetic is discussed. Results: The thermograms of the plantar skin, for the healthy individuals, are: (1) symmetrical, the temperature distribution of the right foot being a mirror image of that of the left foot ; (2) the thermograms of women, on average, are 3°C colder than those of the men; and (3) the temperature distributions decrease distally from the medial longitudinal arch...

BACKGROUND: Direct (DIR) or indirect (IND) revascularization of pedal angiosomes in patients with chronic limb-threatening ischemia (CLTI) has an unclear impact on limb salvage and healing. The aim of this study was to evaluate the outcomes of DIR and IND revascularization in patients with a peroneal bypass and tissue loss. METHODS: We conducted a retrospective study of a prospectively maintained database in two European university centers from 2004 to 2015. We extracted from this database all patients with CLTI and tissue loss who had received a bypass to the peroneal artery...

BACKGROUND: Ischaemic ulcerations have been reported to persist and/or deteriorate despite technically successful revascularisations; a higher incidence of which affects patients with diabetes and critical limb ischaemia. In the context of wound healing, it is unclear if applications of the angiosome concept in 'direct revascularisation' (DR) would be able to aid the healing of chronic foot ulcerations better than the current 'best vessel' or 'indirect revascularisation' (IR) strategy in patients with co-morbid diabetes and critical limb ischaemia...

BACKGROUND: As we enter an age with new approaches to tissue reconstruction, the emphasis on the adage "like for like" has become even more relevant. This study illustrates the potential for several tailored vascularized composite allotransplantation reconstructive techniques and, in particular, for the management of Volkmann contracture. METHODS: Twenty fresh cadaver dissections and 30 archival lead oxide radiographic studies were examined to (1) identify potential upper limb vascularized composite allotransplantation donor sites (i...

BACKGROUND: Low flap complication rates and excellent aesthetic outcomes are now commonplace in breast reconstruction. As a result, attention is now being focussed on minimising donor site morbidity. Despite its potential donor site advantages, the superficial inferior epigastric artery (SIEA) flap is often discounted, given concerns about the high flap failure rates. In this study, we present our experience of using the SIEA flap in breast reconstruction and provide an algorithm based on pre-operative computed tomography angiography (CTA) to aid pre-operative planning...

OBJECTIVE: Direct revascularization (DR), according to the angiosome concept, provides direct blood flow to the site of tissue loss in patients with critical limb ischemia (CLI). DR may lead to improved outcomes; however, evidence for this is controversial. This systematic review and meta-analysis investigated the outcomes of surgical and endovascular DR compared with indirect revascularization (IR) in patients with CLI. METHODS: A systematic review was undertaken using the Cochrane Collaboration specified tool, and a meta-analysis was done according to the MOOSE (Meta-analysis of Observational Studies in Epidemiology) criteria...

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...
