US Volume Flow Assessment to Optimize Angioplasty of Dysfunctional Dialysis Access: The VOLA-II Multicenter Study.

Radiology

November 2024

From the 2nd Department of Radiology, Interventional Radiology Unit, Attikon University General Hospital, 1st Rimini St, GR 12461 Chaidari, Athens, Greece (S.S., P.F., K.P., S.G., E.B., D.K.); Department of Nephrology and Hemodialysis Unit (I.E.G.) and Department of Interventional Radiology (E.B.), Mediterraneo Hospital, Glyfada, Greece; and Department of Interventional Radiology, School of Medicine, Patras University Hospital, Rion, Greece (K.K., P.K.).

Background Digital subtraction angiography and thrill palpation demonstrate limitations when used to assess the outcomes of angioplasty in autologous arteriovenous fistulas (AVFs). Purpose To investigate a new functional quantifiable index of successful angioplasty for failing AVFs using intraprocedural percutaneous US volume flow (VF) measurements. Materials and Methods This prospective, multicenter, single-arm, cohort clinical trial included consecutive patients with indications for fluoroscopically guided balloon angioplasty due to AVF dysfunction between June 2020 and May 2022.

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital malformation. We present a case of an elderly patient with ALCAPA presenting with complete heart block and non-ST-elevation myocardial infarction years after diagnosis and surgical correction. An 81-year-old female with a history of ALCAPA presented to the emergency department with chest pain and progressive mental deterioration.

Unlabelled: Aim of this study is to evaluate any differences in VWF antigen, VWF activity and ADAMTS-13 activity before and after successful and non-successful Percutaneous Transluminal Angioplasty (PTA) in subjects with type 2 diabetes (T2DM) complicated by Chronic limb-threatening ischemia (CLTI) in diabetic foot vasculopathy.

Methods: In this prospective observational pilot study, we enrolled 35 T2DM subjects who underwent lower limb PTA. Transcutaneous oximetry was performed in all patients before and 6 weeks after PTA.

To report a review and meta-analysis of all randomized controlled trials (RCTs) comparing bypass surgery (BS) and endovascular treatment (ET) in infrainguinal peripheral arterial disease (PAD) for several endpoints, such as major and minor amputation, major adverse limb events (MALEs), ulcer healing, time to healing, and all-cause mortality to support the development of the Italian Guidelines for the Treatment of Diabetic Foot Syndrome (DFS). A MEDLINE and EMBASE search was performed to identify RCTs, published since 1991 up to June 21, 2023, enrolling patients with lower limb ischemia due to atherosclerotic disease (Rutherford I-VI). Any surgical BS or ET was allowed, irrespective of the approach, route, or graft employed, from iliac to below-the-knee district.
