Inferior vena cava (IVC) atresia is a rare congenital anomaly. Standardized treatment is not well defined due to its uncommon presentation, with this pathology associated with an increased risk of unprovoked lower extremity deep vein thrombosis (DVT). We present a case of a 32-year-old man who was admitted for bilateral lower extremity edema and pain and was found to have bilateral extensive iliofemoral and femoropopliteal DVT, absence of IVC filling, and extensive tortuous collateralization arising from the pelvic veins to the azygos vein...

PURPOSE: To evaluate the best endovascular treatment for de novo femoropopliteal lesions at long-term follow-up through network meta-analysis of randomized controlled trials. METHODS: Medical databases were searched on September 17, 2023. 17 trials and 7 treatments were selected. Outcomes were primary patency, target lesion revascularization (TLR), major amputation and all-cause mortality at 3 and/or 5 years. RESULTS: Regarding 3-year primary patency, drug-eluting stents (DES) was the best and better than balloon angioplasty (BA; odds ratio [OR], 4...

OBJECTIVE: This Bayesian network meta-analysis sought to evaluate the efficacy of different endovascular treatments for femoropopliteal in-stent restenosis (FP-ISR). METHODS: PubMed, Embase, Cochrane Central Register of Controlled Trials and Web of science for clinical trials from database inception to 31 March 2023, with no language restrictions to retrieve randomized controlled trials (RCTs) or cohort studies evaluating the impact of any kind of endovascular treatments for FP-ISR...

BACKGROUND: Severe calcification often prevents device passage and balloon expansion in cases of lower extremity artery disease. To address this limitation, we introduced a novel calcium modification technique called Rendezvous-PIERCE (R-PIERCE). METHODS: A needle was inserted in a retrograde manner and advanced to touch the tip of an antegrade guidewire within the lesion. Then, the guidewire was advanced into the lumen of the needle to achieve partial guidewire externalization, also known as needle rendezvous...

BACKGROUND: Whether intraluminal drug-coated balloon (DCB) angioplasty is superior to subintimal DCB angioplasty regarding femoropopliteal (FP) chronic total occlusion (CTO) outcomes has not been systematically determined. OBJECTIVES: The aim of this study was to compare the 1-year clinical outcomes of intraluminal and subintimal DCB angioplasty for the treatment of patients with symptomatic FP CTO. METHODS: This subanalysis of POPCORN (Prospective Multi-Center Registry of Drug-Coated Balloon for Femoropopliteal Disease) evaluated 469 lesions in 469 symptomatic patients with lower extremity artery disease who presented with FP CTO and underwent DCB treatment...

This study aimed to compare lower limb events associated with preplanned and finally selected treatment strategies-the validity and usefulness of the physician-chosen strategy were verified.We examined the data of 1003 patients in the registry of multicenter endovascular treatment for superficial femoral and popliteal artery disease study and prospectively enrolled patients who underwent endovascular treatment (EVT) of the femoropopliteal (FP) artery between February 2017 and June 2018 from 67 Japanese institutes...

Below-the-knee (infrapopliteal) atherosclerotic disease, which presents as chronic limb-threatening ischemia (CLTI) in nearly 50% of patients, represents a treatment challenge when it comes to the endovascular intervention arm of management. Due to reduced tissue perfusion, patients usually experience pain at rest and atrophic changes correlated to the extent of the compromised perfusion. Unfortunately, the prognosis remains unsatisfactory with 30% of patients requiring major amputation and a mortality rate of 25% within 1 year...

BACKGROUND: This study evaluated a deep learning (DL) algorithm for detecting vessel steno-occlusions in patients with peripheral arterial disease (PAD). It utilised a private dataset, which was acquired and annotated by the authors through their institution and subsequently validated by two blinded readers. METHODS: A single-centre retrospective study analysed 105 magnetic resonance angiography (MRA) images using an EfficientNet B0 DL model. Initially, inter-reader variability was assessed using the complete dataset...

The 355 nm Auryon laser has been shown to be effective and safe in treating various morphology lesions in the femoropopliteal arteries. There are limited data on the Auryon laser in treating below the knee (BTK) arteries in patients with chronic limb threatening ischemia (CLTI). We present the 30-day efficacy and safety findings from the ongoing Auryon BTK study. Patients with CLTI were prospectively enrolled in the Auryon BTK study between March 2022 and February 2023 in 4 US centers after obtaining informed consent...

BACKGROUND: Although the 1-year clinical outcomes of fluoropolymer-based drug-eluting stents (FP-DES) were favorable for the treatment of real-world femoropopliteal lesions in symptomatic peripheral artery disease (PAD), their performance beyond 1 year remained unknown. The current study determined the 3-year clinical course of FP-DES implantation for real-world femoropopliteal lesions. METHODS: This multicenter, prospective, observational study evaluated 1204 limbs (chronic limb-threatening ischemia, 34...

BACKGROUND: The optimal treatment approach for patients with active venous leg ulcers (VLUs) and post-thrombotic syndrome (PTS) associated with great saphenous vein (GSV) reflux remains unclear. To address this gap, we retrospectively compared the outcomes of patients with post-thrombotic VLU with an intact GSV vs those with a stripped or ablated GSV. METHODS: We retrospectively analyzed data from 48 patients with active VLUs and documented PTS, who were treated at a single center between January 2018 and December 2022...

OBJECTIVE: There is a need for improved outcomes in the endovascular treatment of patients suffering from chronic limb threatening ischaemia (CLTI), highly calcified lesions and chronic total occlusions (CTOs). The helical centreline self expanding BioMimics 3D stent might be particularly useful in these high risk subsets, combining flexibility and fracture resistance with radial strength. Herein, the performance of the BioMimics 3D stent was assessed in these high risk subsets. METHODS: MIMICS-3D is a prospective, multicentre European real world registry...

INTRODUCTION: Endovascular therapy is an established revascularization option for lower limb arterial stenosis with drug-eluting therapy demonstrating promising findings in inhibiting vessel restenosis and improving clinical outcomes post-intervention. However, a 2018 meta-analysis raised considerable concerns for an increased risk of death with paclitaxel-containing balloons and stents. The present study aims to provide an updated systematic review and meta-analysis of safety and efficacy outcomes with paclitaxel-containing devices...

BACKGROUND: The clinical implications of restenosis after drug-coated balloon (DCB) treatment remain unclear. We compared the clinical outcomes between DCB angioplasty for restenosis and de novo femoropopliteal artery lesions. This single-center retrospective study included 571 patients (737 limbs) who underwent either repeat (54 patients, 64 limbs) or de novo DCB (517 patients, 673 limbs) without bailout stenting. After propensity score matching, 49 matched pairs were analyzed. The primary endpoint was the 1-year primary patency, with secondary endpoints including the freedom from target lesion revascularization (TLR), major adverse limb events (MALE), and early restenosis...

INTRODUCTION: Popliteal artery aneurysms (PAAs) pose some challenges in their surgical management and are often treated by exclusion and bypass procedures. However, post-operative complications, such as endoleaks and sac growth, can occur, potentially leading to serious consequences. Endoleaks, characterised by persistent flow within the aneurysm sac after repair, can cause sac expansion, increasing the risk of adverse outcomes, including the formation of cutaneous fistulae, a rare but potentially severe complication...

AIM: The aim of this study was to investigate the potential of novel automated machine learning (AutoML) in vascular medicine by developing a discriminative artificial intelligence (AI) model for the classification of anatomical patterns of peripheral artery disease (PAD). MATERIAL AND METHODS: Random open-source angiograms of lower limbs were collected using a web-indexed search. An experienced researcher in vascular medicine labelled the angiograms according to the most applicable grade of femoropopliteal disease in the Global Limb Anatomic Staging System (GLASS)...

Background and Objectives : The aim of this study was to evaluate the clinical outcomes of patients suffering from chronic limb-threatening ischemia (CLTI) and tissue loss treated with primary isolated femoral bifurcation endarterectomy (FBE) or with FBE combined with bypass surgery. Materials and Methods : This retrospective study was performed in a tertiary university-based care centre. Between January 2008 and December 2019, a prospectively collected database of patients suffering from CLTI and tissue loss and undergoing either primary FBE (group A) or FBE in combination with bypass surgery (group B) was analysed...
