CVIR. Interventional Radiology of Male Varicocele: Current Status

Vittorio Iaccarino, Pietro Venetucci

Abstract: Varicocele is a fairly common condition in male individuals. Although a minor disease, it may cause infertility and testicular pain. Consequently, it has high health and social impact. Here we review the current status of interventional radiology of male varicocele. We describe the radiological anatomy of gonadal veins and the clinical aspects of male varicocele, particularly the physical examination, which includes a new clinical and ultrasound Doppler maneuver. The surgical and radiological treatment options are also described with the focus on retrograde and antegrade sclerotherapy, together with our long experience with these procedures. Last, we compare the outcomes, recurrence and persistence rates, complications, procedure time and cost-effectiveness of each method. It clearly emerges from this analysis that there is a need for randomized multicentre trials designed to compare the various surgical and percutaneous techniques, all of which are aimed at occlusion of the anterior pampiniform plexus.

CVIR. Phlegmasia Caerulea Dolens in a Patient With an Inferior Vena Cava Filter: Treatment of Massive Iliocaval Thrombosis Using Local Intravenous Catheter-Directed Thrombolysis

Daniel Cookson, Stuart Caldwell

Abstract: Phlegmasia caerulea dolens (PCD) is a potentially disastrous complication of inferior vena cava filter insertion, and its optimum management has not been clearly established. We present a case report of a patient with pulmonary embolism and acute adrenal haemorrhage who developed PCD secondary to massive iliocaval thrombosis after insertion of a Cook Celect removable filter. Local intravenous catheter-directed thrombolysis (CDT), followed by systemic anticoagulation, achieved limb salvage and virtual resolution of symptoms at 3 months without complications. CDT can be a successful primary treatment of filter-associated PCD and can be safe in selected patients with acute nontraumatic haemorrhage. Systemic anticoagulation may subsequently restore complete venous patency and may therefore be a useful approach to postthrombolysis management of residual iliocaval thrombus when filter removal is indicated.

CVIR. The Optional VenaTech™ Convertible™ Vena Cava Filter: Experimental Study in Sheep

Alain F. Le Blanche, Jean-Baptiste Ricco, Michel Bonneau, Philippe Reynaud

Purpose: Retrieval of optional caval filters may be impaired by filter tilting, migration, fracture, or embedding in the IVC wall. The goal of this experimental study was to evaluate a new optional filter, convertible by unlocking and removing the filter head.

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Changes in Glomerular Filtration Rate After Renal Revascularization Correlate With Microvascular Hemodynamics and Inflammation in Swine Renal Artery Stenosis

Alfonso Eirin, MD, Behzad Ebrahimi, PhD, Xin Zhang, MD, Xiang-Yang Zhu, MD, PhD, Hui Tang, MD, PhD, John A. Crane, Amir Lerman, MD, Stephen C. Textor, MD and Lilach O. Lerman, MD, PhD

Background—The selection of patients with renal artery stenosis (RAS) likely to improve glomerular filtration rate (GFR) after percutaneous transluminal renal angioplasty is difficult. We examined basal hemodynamic and inflammatory factors linked to improved stenotic kidney (STK) function after percutaneous transluminal renal angioplasty in swine RAS.

Purpose: Treatment of patients who have metastatic colorectal cancer (CRC) by using a combination of hepatic arterial infusion chemotherapy (HAIC) and systemic chemotherapy has resulted in promising clinical outcomes. Additionally, image-guided HAIC is reported to be less invasive and distribute drugs more accurately than surgical HAIC. The purpose of this study was to assess the combination of image-guided delivery of fluorouracil through HAIC and systemic irinotecan in a multicenter phase I/II study.

JVIR. Cementoplasty of Metastases of the Proximal Femur: Is It a Safe Palliative Option?

Frederic Deschamps, MDemail address , Geoffroy Farouil, MD , Antoine Hakime, MD , Ali Barah, MD , Boris Guiu, MD , Christophe Teriitehau, MD , Anne Auperin, MD , Thierry deBaere, MD

Purpose: Percutaneous cementoplasty has proved very effective for the palliation of pain from bone metastases. However, several studies argue that it should be contraindicated for metastases that are located in the proximal femur because of inadequate bone consolidation. The aim of this study was to evaluate the risk factors for fracture despite performing cementoplasty for metastases of the proximal femur.
