Imaging of Deep Venous Pathology.

Imaging plays an important role in the identification and assessment of clinically suspected venous pathology. The purpose of this article is to review the spectrum of image-based diagnostic tools used in the investigation of suspected deep vein disease, both obstructive (deep vein thrombosis and post-thrombotic vein changes) as well as insufficiency (e.g.

Clinical impact of assessing thrombus age using magnetic resonance venography prior to catheter-directed thrombolysis.

Objectives: Magnetic resonance venography (MRV) is underutilized in the evaluation of thrombus properties prior to endovascular treatment but may improve procedural outcomes. We therefore investigated the clinical impact of using a dedicated MRV scoring system to assess thrombus characteristics prior to endovascular intervention for iliofemoral deep vein thrombosis (DVT).

Methods: This is a post hoc analysis of data from the CAVA trial ( Clinicaltrials.

Cystic Adventitial Disease of the (ilio) Femoral Artery with a Connection to the Hip Joint: Case Report and a Review of the Literature.

Objective: Cystic adventitial disease (CAD) is an uncommon non-atherosclerotic peripheral vessel disease, most often seen in the popliteal artery. Only a small number of cases involving the (ilio) femoral artery have been reported. The case of a 48 year old female with CAD of the left femoral artery with a connection of the disease to the hip joint on pre-operative imaging confirmed during surgery is described.

Development of a Management Algorithm for Acute and Chronic Radiation Urethritis and Cystitis.

Objective: The purpose of this review was to summarize the current literature on the assessment and treatment of radiation urethritis and cystitis (RUC) for the development of an evidenced-based management algorithm.

Material And Methods: The PubMed/MEDLINE database was searched by a multidisciplinary group of experts in January 2021.

Results: In total, 48 publications were identified.

Amplatzer Vascular Plug Embolization in Two Patients with Ruptured Infrarenal Aortic Aneurysm and Aortoiliac Occlusive Disease.

Mortality for ruptured abdominal aortic aneurysm (AAA) is known to be high. When left untreated, it is nearly always fatal. Standard treatment options include open surgery and endovascular aneurysm repair (EVAR), but both techniques have limitations.

Association of Successful Ultrasound-Accelerated Catheter-Directed Thrombolysis with Postthrombotic Syndrome: A Post Hoc Analysis of the CAVA Trial.

Background:  The CAVA trial did not show the anticipated risk reduction for postthrombotic syndrome (PTS) after thrombus removal via additional ultrasound-accelerated catheter-directed thrombolysis (UACDT) in patients with acute iliofemoral deep vein thrombosis (IFDVT). Difficulties in achieving an effective degree of recanalization through thrombolysis may have influenced outcomes. We therefore assessed whether successful UACDT (restored patency ≥ 90%) did reduce the development of PTS.

Ultrasound-accelerated catheter-directed thrombolysis versus anticoagulation for the prevention of post-thrombotic syndrome (CAVA): a single-blind, multicentre, randomised trial.

Background: Early thrombus removal might prevent post-thrombotic syndrome by preserving venous function and restoring flow. Previous trials comparing additional catheter-directed thrombolysis to standard treatment showed conflicting outcomes. We aimed to assess the benefit of additional ultrasound-accelerated catheter-directed thrombolysis for the prevention of post-thrombotic syndrome compared with standard therapy in patients with iliofemoral deep-vein thrombosis.

Gadobutrol versus gadofosveset-trisodium in MR venography of the lower extremities.

Objectives: MR venography (MRV) protocols have used bloodpool contrast agents and long scan sequences to identify patients suitable for treatment and preoperatively. However, variable availability of bloodpool contrast agents, high costs and a need to shorten acquisition times for routine MR protocols hamper everyday practice.

Materials: 20 patients (11 men; mean age 54 ± 11.

Abdominal and pubic collateral veins as indicators of deep venous obstruction.

Objective: Chronic deep venous obstruction can cause a significant loss of quality of life, although it can be treated successfully by stenting. A clear referral pattern for additional imaging is warranted in patients with lower limb complaints. The aim of this study was to determine the value of clinically visible abdominal wall collateral veins in the diagnosis of a potentially treatable deep venous obstruction.

Fast and accurate liver volumetry prior to hepatectomy.

Background: Volumetric assessment of the liver is essential in the prevention of postresectional liver failure after partial hepatectomy. Currently used methods are accurate but time-consuming. This study aimed to test a new automated method for preoperative volumetric liver assessment.

The value of hemodynamic measurements by air plethysmography in diagnosing venous obstruction of the lower limb.

Objective: Air plethysmography (APG) is a functional, noninvasive test that can assess volumetric changes in the lower limb and might therefore be used as a diagnostic tool in chronic deep venous disease. However, use of APG in chronic deep venous obstructive disease remains debatable. This study assessed the clinical value of APG in identifying chronic deep venous obstruction.

The Role of Spectral Tissue Sensing During Lumbar Transforaminal Epidural Injection.

Spectral tissue sensing (STS) exploits the scattering and absorption of light by tissue. The main objective of the present study was to determine whether STS can discriminate between correct and incorrect placement of the needle tip during lumbar transforaminal epidural injection. This was a single-blind prospective observational study in 30 patients with lumbar radicular pain scheduled for lumbar transforaminal epidural injection.

Clinical Evaluation of Wound Healing in Split-Skin Graft Donor Sites Using Microscopic Quantification of Reepithelialization.

Objective: Impaired or delayed wound healing is a common health problem. However, it remains challenging to predict whether wounds in patients will heal without complication or will have a prolonged healing time. In this study, the authors developed an objective screening tool to assess wound healing using microscopic quantification of reepithelialization in a split-thickness skin graft wound model and used this tool to identify risk factors for defective wound healing.

Thrombectomy without lysis: the future?

The results of the CaVent-study and the expected results of the ATTRACT and CAVA trials will form the base of evidence to support that rapid cloth removal is beneficial for patients with iliofemoral DVT. Although beneficial, there are still significant risks associated with this therapy. Therefore alternative methods for rapid cloth removal without lysis are a potential valid alternative.

Efficacy of radiation safety glasses in interventional radiology.

Purpose: This study was designed to evaluate the reduction of the eye lens dose when wearing protective eyewear in interventional radiology and to identify conditions that optimize the efficacy of radiation safety glasses.

Methods: The dose reduction provided by different models of radiation safety glasses was measured on an anthropomorphic phantom head. The influence of the orientation of the phantom head on the dose reduction was studied in detail.

Ultrasound-accelerated catheter-directed thrombolysis in acute iliofemoral deep venous thrombosis.

Background: Iliofemoral deep venous thrombosis (DVT) is associated with a high incidence of the post-thrombotic syndrome. The current CHEST guidelines suggest that catheter-directed thrombolysis can be used for patients with acute iliofemoral DVT and severe leg complaints. Current literature shows that catheter-directed thrombolysis increases patency of the affected tract and may reduce post-thrombotic complications, but treatment time and bleeding complications are high.

Minimally invasive treatment of chronic iliofemoral venous occlusive disease.

Background: As one of the primary etiologies of the post-thrombotic syndrome, chronic venous occlusion is a huge burden on patient quality of life and medical costs. In this study, we evaluate the short-term and midterm results of endovenous recanalization by angioplasty and stenting in chronic iliofemoral deep venous occlusions.

Methods: This is a retrospective observational study set in a tertiary medical referral center.

[Catheter-directed thrombolysis in iliofemoral deep-vein thrombosis].

Despite optimal treatment of acute deep-vein thrombosis (DVT) there is a great chance of recurrent DVT and development of post-thrombotic syndrome (PTS) in the long term. The degree of spontaneous recanalization differs per patient and per thrombus location. 90% of all femoropopliteal occlusions will fully recanalize within 1 year; however, in the case of an iliofemoral thrombosis, recanalization occurs only in a minority of cases.
