Angiosome-Targeted Infrapopliteal Angioplasty: Impact on Clinical Outcomes-An Observational Study.

: Revascularization based on the angiosome concept (AC) is a controversial subject because there is currently no clear evidence of its efficacy, due to the heterogeneity of patients (multiple and diverse risk factors and comorbidities, multiple variations in the affected angiosomes). Choke vessels change the paradigm of the AC, and the presence or absence of the plantar arch directly affects the course of targeted revascularization. The aim of this study was to evaluate the effect of revascularization based on the AC in diabetic patients with chronic limb-threatening ischemia (CLTI).

Clinical Implications of Diabetic Peripheral Neuropathy in Primary Infrapopliteal Angioplasty Approach for Neuro-Ischemic Foot Wounds.

Background: To assess the clinical effects of diabetic peripheral neuropathy (DPN) in patients with chronic limb-threatening ischemia (CLTI) treated by primary infrapopliteal angioplasty for neuro-ischemic Rutherford 5, foot wounds.

Materials And Methods: Over a 10-year period (2009-2019), a series of 304 diabetic ischemic limbs adding or not evincible neuropathic affectation were treated by primary infrapopliteal angioplasty and their files were retrospectively reviewed. Mean length of treated arterial lesions was 6.

Grades of Below-the-Ankle Arterial Occlusive Disease following the Angiosome Perfusion: A New Morphological Assessment and Correlations with the Inframalleolar GVG Stratification in CLTI Patients.

Purpose: To assess a specific classification of the foot atherosclerotic disease concerning the angiosomal source arteries, the connected foot arches and attached collaterals for Rutherford 5, CLTI patients. To compare eventual analogies of this novel grading system with previously reported GLASS/GVG inframalleolar patterns of occlusive disease (P0-P2).

Materials And Methods: A series of 336 ischemic feet (221 diabetics) were selected and retrospectively analyzed.

Primary infragenicular angioplasty for diabetic neuroischemic foot ulcers following the angiosome distribution: a new paradigm for the vascular interventionist?

The angiosome principle was first described by Jan Taylor in 1987 in the plastic reconstructive surgery field, providing useful information on the vascular anatomy of the human body. Specifically concerning foot and ankle pathology, it may help the clinician to select better vascular access and specific strategies for revascularization. This knowledge may be particularly beneficial when treating diabetic neuroischemic foot wounds associated with particularly aggressive atherosclerotic disease and a poor collateral circulation.

A reliable approach to diabetic neuroischemic foot wounds: below-the-knee angiosome-oriented angioplasty.

Purpose: To evaluate the clinical benefit in wound healing and limb preservation after primary below-the-knee angioplasty guided by an angiosome model of perfusion in diabetic patients with neuroischemic foot ulcers.

Methods: From September 2001 to April 2010, 232 limb-threatening neuroischemic wounds in 208 diabetic patients (147 men; mean age 74.3 years, range 42-97) were treated by below-the-knee endoluminal and/or subintimal angioplasty.

Deep calf veins arterialization for inferior limb preservation in diabetic patients with extended ischaemic wounds, unfit for direct arterial reconstruction: preliminary results according to an angiosome model of perfusion.

Aim Of The Study: The study proposes to evaluate the limb salvage in diabetic ischemic limbs with foot wounds, where all types of common arterial reconstructions have previously failed or were impracticable, by using the "SAVES" technique (selective arterio-venous endoluminal switch) for deep calf veins arterialization upon an angiosomes model of distribution.

Materials And Methods: Since January 2001 until September 2009, a series of 26 limbs with threatening ischemic wounds in 25 diabetic patients at high risk for major amputation and no feasible conventional revascularizations, were treated by the hybrid (surgical and endovascular) SAVES technique and were retrospectively reviewed. The method consists in selective arterialization of the deep calf veins with synchronous endoluminal exclusion of the collaterals, guided by an angiosomes- model of vascularization.

Filter-protected carotid stenting via a minimal cervical access with transitory aspirated reversed flow during initial passage of the target lesion.

Purpose: To evaluate the preliminary results of filter-protected carotid artery stenting (CAS) via a minimal cervical access, with temporary common carotid artery (CCA) occlusion and aspiration in selected high-risk candidates for carotid endarterectomy.

Methods: Since February 2002, 26 patients (17 men; mean age 73.7 years, range 54-98) at high surgical risk according to the SAPPHIRE eligibility criteria underwent 29 transcervical CAS procedures under filter protection.
