BACKGROUND: Few reports have described the effects of medication on the wound healing of ischemic ulcers after revascularization. This study was conducted to investigate the effects of cilostazol on wound healing in patients who underwent infrainguinal bypass for ischemic tissue loss. METHODS: Two hundred and sixty-three limbs undergoing de novo infrainguinal bypass for tissue loss from January 2004 to December 2015 were divided into two groups based on whether or not cilostazol was administered after surgery...

Studies examining thick skin of the thumb pad have challenged the existence of an arterial plexus in the papillary dermis. Instead of a plexus, discrete arterial units, interconnected by arterio-arterial anastomoses, were identified. We hypothesise that the dermal arteries of thin skin are arranged likewise and that there are fewer arterio-arterial anastomoses in the centre of an angiosome than in zones where neighbouring angiosomes overlap. To test these hypotheses, we examined the dermal arteries in the centre of the cutaneous angiosome of the descending genicular artery (DGA) and its zone of overlap with neighbouring angiosomes...

Objectives The main factor in the healing of foot ulcers in diabetic patients is adequate perfusion. There is no consensus on whether direct or indirect revascularization is more effective in leg revascularization. At the centre of that debate, there is a disagreement about whether collateral circulation is sufficient or not. Our aim is to evaluate collateral circulation activity between angiosomes in the feet of diabetic patients by evaluating the level of occlusion in leg arteries and comparing the angiosome regions that have necrosis...

OBJECTIVE/BACKGROUND: To evaluate complete wound healing and limb salvage rates in patients with critical limb ischaemia (CLI) with concurrent foot ulceration/gangrene who underwent angiosome targeted infrapopliteal balloon angioplasty. METHODS: This was a prospective observational study. In total, 212 patients who underwent successful infrapopliteal balloon angioplasty to assist wound healing and achieve limb salvage were included from June 2014 to March 2016. Propensity score matching was developed to compare complete wound healing, 1 year amputation free survival (AFS), and limb salvage rates between the two study groups (direct revascularisation [DR] and indirect revascularisation [IR])...

OBJECTIVES: The "angiosome" concept as a model for decision making in revascularisation of patients with critical limb ischaemia (CLI) has been subject to lively discussion in recent years. The aim of this prospective pilot study was to use intra-operative fluorescence angiography to provide further data on the angiosome concept on the level of microcirculation after tibial bypass surgery. DESIGN, MATERIALS, AND METHODS: This was a prospective analysis of 40 patients presenting with CLI Rutherford stage IV to VI before and after tibial bypass surgery...

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...

PURPOSE: To assess the radiopathologic correlation following Yttrium-90 transarterial radioembolization (TARE) of hepatocellular carcinoma (HCC) using variable radiodosimetry to identify imaging surrogates of histologic response. METHODS: Twelve patients with HCC underwent ablative (≥ 190 Gy) and/or non-ablative (< 190 Gy) TARE delivered in a segmental, lobar, or combined fashion as a surgical neoadjuvant or bridge to transplantation. Both targeted tumor and treatment angiosome were analyzed before and after TARE utilizing hepatocyte-specific contrast-enhanced MRI or contrast-enhanced CT...

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...

STUDY QUESTION: Can the baboon uterus support a gestation to livebirth with an angiosome using microsurgically anastomosed utero-ovarian vessels and lacking uterine arteries and veins? SUMMARY ANSWER: Our angiosome model allows healthy livebirth albeit with risk of fetal growth restriction and stillbirth. WHAT IS KNOWN ALREADY: Uterine transplant can provide livebirth in humans, but requires a living donor to undergo a prolonged laparotomy for hysterectomy...

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...
