Pulmonary Artery Embolization in the Management of Hemoptysis Related to Lung Tumors.

(1) Background: Bronchial artery embolization has been shown to be effective in the management of neoplastic hemoptysis. However, knowledge of pulmonary artery embolization is lacking. The aim of this study was to evaluate the safety and efficacy of pulmonary artery embolization in patients presenting with hemoptysis related to lung tumors.

Ilio-femoral venous stenting for post-thrombotic syndrome in women of childbearing age: efficacy and impact of pregnancy-a multi-center study by the French Society of Cardiovascular Imaging.

Objective: We investigated the efficacy of iliofemoral venous stenting in women of childbearing age treated for post-thrombotic syndrome (PTS) and assessed the influence of pregnancy on stent occlusion.

Methods: A retrospective analysis was conducted on women of childbearing age who underwent endovascular stenting for PTS due to chronic iliocava occlusion across 15 centers from 2009 to 2020. The study assessed pregnancy rates, primary patency rates, secondary patency rates, and clinical efficacy using the Villalta score for PTS severity and the Chronic Venous Disease Quality of Life Questionnaire - version 20 (CIVIQ-20), 6-12 months after the procedure.

Purpose: To report the effectiveness of pharmacomechanical catheter-directed thrombolysis (PCDT) in the management of acute iliofemoral deep venous thrombosis (DVT) via the jugular vein using a slow rotation and large-tip device (SRD) in a large cohort of patients.

Material And Methods: From 2011 to 2021, 277 patients (mean age 45 years, 59.2% women) were treated in 6 centres with PCDT for ilio-fémoral DVT.

Patient-Reported Outcomes of Endovascular Treatment of Post-Thrombotic Syndrome: Ancillary Study of a French Cohort.

Excellent outcomes of angioplasty/stenting for the post-thrombotic syndrome (PTS) have been reported, notably regarding objective criteria in the vast French SFICV cohort. Differences may exist between patient-reported and objective outcomes. We investigated this possibility by using validated scales because significative correlations are discordant in the literature between patency and patient-reported characteristics.

Left gastric vein embolization during TIPS placement for acute variceal bleeding has no effect on bleeding recurrence: Results of a multicenter study.

Purpose: The purpose of this study was to evaluate whether concomitant left gastric vein embolization (LGVE) during transjugular intrahepatic portosystemic shunt (TIPS) for acute variceal hemorrhage could reduce the risk of bleeding recurrence.

Material And Method: A national multicenter observational study was conducted in 14 centers between January 2019 and December 2020. All cirrhotic patients who underwent TIPS placement for acute variceal bleeding were included.

Safety of High-Frequency Jet Ventilation During Image-Guided Thermal Ablation Procedures.

Rationale And Objective: Percutaneous thermal ablative technique is a common radiological procedure for malignant lesions treatment. Controlled assisted ventilation during general anesthesia is the usual mode of ventilation, but high-frequency jet ventilation (HFJV) can be a helpful alternative for the operator. The objective was to evaluate the safety of HFJV during thermal ablation procedures.

Predictive Factors of Stent Patency in Iliofemoral Venous Diseases in a Multicentre Cohort Study.

Objective: This study assessed primary stent patency predictive factors in three groups of patients with history of lower limb (LL) vein thrombosis: non-thrombotic iliac vein lesion (NIVL), acute deep vein thrombosis (aDVT), and post-thrombotic syndrome (PTS).

Methods: Consecutive patients from January 2014 to December 2020 with history of LL vein stenting from seven hospitals were included. All patients received an iliac or common femoral venous stent and had at least a six month follow up available with stent imaging.

Cryoablation of Soft Tissues Low-Flow Vascular Malformations: Clinical Outcomes and Safety.

Objective: To report the clinical effectiveness and the safety of cryoablation in first or second-line therapy in symptomatic soft tissues vascular malformation, a mini-invasive therapeutic alternative to sclerotherapy or surgery.

Materials And Methods: This retrospective and monocentric study included patients with symptomatic low-flow vascular malformation. The interventions were carried out under computed tomography (CT) scan, Cone-beam CT (CBCT) and/or USA guidance.

Infected pancreatic necrosis complicating severe acute pancreatitis in critically ill patients: predicting catheter drainage failure and need for necrosectomy.

Background: Recent guidelines advocate a step-up approach for managing suspected infected pancreatic necrosis (IPN) during acute pancreatitis. Nearly half the patients require secondary necrosectomy after catheter drainage. Our primary objective was to assess the external validity of a previously reported nomogram for catheter drainage, based on four predictors of failure.

Feasibility of Endovascular Recanalization in Post-Thrombotic Syndrome of Intentionally Interrupted Inferior Vena Cava.

Purpose: Surgical plication of inferior vena cava was commonly used until the 1980s for prevention of pulmonary embolism, associated with high incidence of post-thrombotic syndrome (PTS). This study aims to assess the feasibility and safety of endovascular iliocaval recanalization after intentionally surgically interrupted inferior vena cava by external plicating clip.

Materials And Methods: Endovascular iliocaval recanalizations in relation to previous vena cava clip plication were extracted from the retrospective French multicentre database and further analysed.

Imaging-guided interventions modulating portal venous flow: Evidence and controversies.

Portal hypertension is defined by an increase in the portosystemic venous gradient. In most cases, increased resistance to portal blood flow is the initial cause of elevated portal pressure. More than 90% of cases of portal hypertension are estimated to be due to advanced chronic liver disease or cirrhosis.

Pharmaco-mechanical catheter-directed thrombolysis versus recanalization and stenting for post thrombotic syndrome after lower limb deep vein thrombosis: a comparative study.

Background: Endovenous interventional procedures can be used in addition to therapeutic anticoagulation to treat deep vein thrombosis in selected patients with proximal vein involvement (vena cava, iliac and/or common femoral). The aim of this study was to compare venous patency and the post-thrombotic syndrome (PTS) in patients treated with pharmaco-mechanical catheter-directed thrombolysis (PMT) versus recanalization-stenting for PTS after a proximal lower limb deep vein thrombosis.

Methods: Between January 2014 and December 2020, this retrospective and monocentric study included patients with very symptomatic acute iliofemoral deep vein thrombosis treated with PMT within 21 days after diagnosis (PMT group) and patients with PTS caused by chronic venous obstruction treated with recanalization and stenting (CRS group).

Short- and Mid-Term Outcomes of Endovascular Stenting for the Treatment of Post-Thrombotic Syndrome due to Iliofemoral and Caval Occlusive Disease: A Multi-Centric Study from the French Society of Diagnostic and Interventional Cardiovascular Imaging (SFICV).

Purpose: To assess the results of endovascular treatment in a large population of patients suffering from post-thrombotic syndrome (PTS) due to iliocaval occlusive disease.

Methods: In this retrospective multi-center study, 698 patients treated by stenting for PTS in 15 French centers were analyzed. Primary, primary assisted, and secondary patency rates were assessed, and clinical efficacy was evaluated using Villalta and Chronic Venous Insufficiency Questionnaire in 20 questions (CIVIQ-20) scores.

Venous congestion as a central mechanism of radiculopathies.

Compression of roots/nerves can disrupt some of their functions, but does not necessarily cause pain. This is illustrated by the frequency of nearly asymptomatic spinal stenosis or disc herniations. In fact, pain of radiculopathies (and nerve entrapments) may mostly be the consequence of intraneural oedema induced by microscopical venous stasis around roots/spinal ganglia (or nerves) not or poorly shown by imaging.

Angiographic findings and outcomes after embolization of patients with suspected postabortion uterine arteriovenous fistula.

Introduction: The purpose of this study is to assess the angiographic incidence of uterine arteriovenous fistula (UAVF) in women referred for a high ultrasonographic suspicion in a postabortion setting and to evaluate the safety, efficacy and impact on further fertility of uterine artery embolization (UAE) in this indication.

Materials And Methods: A monocentric retrospective study of 31patients managed by uterine artery embolization for suspected UAVF after spontaneous or induced first trimester abortion. The diagnosis of UAVF was confirmed when an early venous drainage was identified on the angiogram.

Effect of Prophylactic Embolization on Patients With Blunt Trauma at High Risk of Splenectomy: A Randomized Clinical Trial.

Importance: Splenic arterial embolization (SAE) improves the rate of spleen rescue, yet the advantage of prophylactic SAE (pSAE) compared with surveillance and then embolization only if necessary (SURV) for patients at high risk of spleen rupture remains controversial.

Objective: To determine whether the 1-month spleen salvage rate is better after pSAE or SURV.

Design, Setting, And Participants: In this randomized clinical trial conducted between February 6, 2014, and September 1, 2017, at 16 institutions in France, 133 patients with splenic trauma at high risk of rupture were randomized to undergo pSAE or SURV.

Impact of prior antibiotics on infected pancreatic necrosis microbiology in ICU patients: a retrospective cohort study.

Background: Recent guidelines advise against prophylactic antibiotics in patients with necrotizing pancreatitis, advocating instead a step-up drainage and necrosectomy strategy with antibiotics as dictated by microbiological findings. However, prompt antibiotic therapy is recommended in patients with sepsis or septic shock, a possible presentation of infected pancreatic necrosis (IPN). Consequently, in many critically ill patients with IPN, pancreatic samples are collected only after broad-spectrum antibiotic therapy initiation.

National dose reference levels in computed tomography-guided interventional procedures-a proposal.

Objectives: To establish national reference levels (RLs) in interventional procedures under CT guidance as required by the 2013/59/Euratom European Directive.

Methods: Seventeen categories of interventional procedures in thoracic, abdominopelvic, and osteoarticular specialties (percutaneous infiltration, vertebroplasty, biopsy, drainage, tumor destruction) were analyzed. Total dose length product (DLP), number of helical acquisitions (NH), and total DLP for helical, sequential, or fluoroscopic acquisitions were recorded for 10 to 20 patients per procedure at each center.

Management of vascular and nonvascular complications following pancreas transplantation with interventional radiology.

Pancreas transplantation exposes to high rates of complications, either vascular (thrombosis, stenosis, pseudoaneurysm, arteriovenous fistula) or nonvascular (fluid collection, graft rejection). With advances in percutaneous and endovascular techniques, interventional radiologists are increasingly involved in the management of these complications. In this article, we review the anatomical considerations relevant to pancreas transplantation, the techniques used for image-guided interventions for vascular and nonvascular complications, and the expected outcomes of these interventions.
