Single institutional experience of peripheral applications of a liquid embolic agent: Ethylene Vinyl Alcohol Copolymer.

Objective: To evaluate the safety and efficacy of ethylene vinyl alcohol (EVOH) copolymer for the treatment of a variety of peripheral vascular pathologies.

Results: Between October 2010 and October 2017, 43 patients who underwent total 54 EVOH embolization procedures for the treatment of peripheral vascular pathologies were included. The cases which involved the use of EVOH for the treatment of nonvascular, neurologic, ophthalmologic, otolaryngologic or head-neck pathologies were excluded.

Percutaneous embolization using a combination of liquid embolic agents for the treatment of a large disfiguring venous malformation.

A 25-year-old man with a venous malformation (VM) along the anterior and posterolateral aspects of the right chest wall presented with progressive enlargement of VM, chest wall pain, and physical disfigurement. Because of the complexity and size of the VM, a staged multidisciplinary team approach (ie, percutaneous embolization) followed by surgical resection and tissue-skin grafting was used. The percutaneous embolization was achieved with a combination of liquid embolic agents including -butyl cyanoacrylate for the superficial cutaneous component and ethylene vinyl alcohol copolymer for the deeper subcutaneous component of the VM.

Research Priorities in Pelvic Venous Disorders in Women: Recommendations from a Multidisciplinary Research Consensus Panel.

Pelvic venous disorders (PeVDs) in women can present with chronic pelvic pain, lower-extremity and vulvar varicosities, lower-extremity swelling and pain, and left-flank pain and hematuria. Multiple evidence gaps exist related to PeVDs with the consequence that nonvascular specialists rarely consider the diagnosis. Recognizing this, the Society of Interventional Radiology Foundation funded a Research Consensus Panel to prioritize a research agenda to address these gaps.

Successful embolization of a enterocutaneous fistula tract with Onyx 34 following low anterior resection for rectal cancer.

Enterocutaneous fistulas (ECFs) can be one of the complications found after surgical intervention for rectal cancer. Interventional modalities consisting of surgical, endoscopic, and radiological methods are often implemented to treat postoperative symptomatic complications. We present the case of 61-year-old Caucasian man who presented to us with a recent diagnosis of rectal cancer that had invaded the levators as well as anteriorly into the prostate, and who underwent low anterior resection with a diverting loop ileostomy.

A new occlusion device: application of the ArtVentive endoluminal occlusion system (EOS)--first in human clinical trial.

Purpose: The purpose of this study was to determine the safety and efficacy of a new endoluminal occlusion device, ArtVentive endoluminal occlusion system (EOS), to occlude the spermatic vein in symptomatic males with varicoceles.

Methods: The ArtVentive EOS device has been developed for percutaneous, peripheral occlusion of the peripheral arterial and venous vasculature. The system is comprised of an implantable occlusion device and a delivery catheter.

Use of the 8-F angio-seal vascular closure device in large-caliber arteriotomies.

Purpose: To evaluate the feasibility and safety of using the 8-F Angio-Seal vascular closure device (VCD) to seal large-caliber (>8-F) access sites during percutaneous endovascular interventions.

Methods: A retrospective review was undertaken of 42 consecutive patients (34 men; mean age 67.8 years, range 36-94) undergoing percutaneous peripheral interventions with sheaths ranging from 9-F to 12-F and subsequent closure using 8-F Angio-Seal VCDs.

Emergency endovascular stenting of the right iliac artery in a patient with secondary haemorrhage following transplant nephrectomy.

A patient presented with abdominal pain, hypotension and a retroperitoneal haematoma 5 days after transplant nephrectomy. Vascular injury sustained from transplant nephrectomy was repaired using endovascular techniques. Several known advantages to endovascular repair include: (1) intervention by a less invasive approach, (2) performance under local anaesthesia, (3) association with a shorter hospital stay and (4) reduction in morbidity and mortality.

Radiologic techniques and effectiveness of angiography to diagnose and treat acute upper gastrointestinal bleeding.

The use of catheter-based techniques to treat upper gastrointestinal hemorrhage has evolved considerably over the past few decades. At present, the state-of-the-art interventional suites provide optimal imaging. Coupled with advanced catheter technology, the two may be used to manage and treat the patient with acute upper gastrointestinal hemorrhage.

Prophylactic inferior vena cava filters in high-risk bariatric surgery.

Background: Bariatric patients are at significant risk for venous thromboembolism (VTE) and a subset may benefit from retrievable inferior vena cava filters (rIVCFs). Optimal VTE prophylaxis and a consensus on factors which make bariatric patients high risk have not been established. This study describes our experience with the use of rIVCFs in combination with chemoprophylaxis for high-risk bariatric surgery patients.

The safety and effectiveness of the retrievable option inferior vena cava filter: a United States prospective multicenter clinical study.

Purpose: To evaluate the safety and effectiveness of the retrievable Option inferior vena cava (IVC) filter in patients at risk for pulmonary embolism (PE).

Materials And Methods: This was a prospective, multicenter, single-arm clinical trial. Subjects (N = 100) underwent implantation of the IVC filter and were followed for 180 days; subjects whose filters were later removed were followed for 30 days thereafter.

Technical success and safety of retrieval of the G2 filter in a prospective, multicenter study.

Purpose: To assess the technical success and safety for retrieval of the G2 filter.

Materials And Methods: The authors performed a prospective, multicenter study of 100 patients with temporary indication for caval interruption. Patients were enrolled consecutively between December 2005 and July 2006.

Pelvic congestion syndrome: diagnosis and treatment.

The diagnosis of pelvic congestion syndrome (PCS) continues to challenge all physicians involved especially those in such specialties as anesthesia, gastroenterology, general surgery, obstetrics and gynecology, and interventional radiology. When other pelvic pathology is ruled out, an interventional radiologist may be consulted for additional evaluation and treatment of PCS. A heightened awareness and clinical suspicion for the specific symptomatology and associated findings may bring about a more rapid progression toward treatment.

Venous thromboembolic disease: the use of "optional" inferior vena cava filters.

Approximately 140,000 to 200,000 patients die as a result of pulmonary embolism in the United States each year. If the diagnosis is made and therapy initiated, the mortality rate drops to 8%. Vena cava filters play a role in the management of patients with thromboembolic disease.

Catheter-directed thrombolysis with the Endowave system in the treatment of acute massive pulmonary embolism: a retrospective multicenter case series.

Purpose: To evaluate the efficacy of thrombolysis with the EndoWave peripheral infusion system in the treatment of patients with massive pulmonary embolism (PE) as compared to patients treated with catheter-directed thrombolysis.

Materials And Methods: Ten patients (five men and five women; age range, 31-85 years; mean age, 54.20 years) with massive acute PE (17 lesions) were treated with ultrasonography (US)-assisted catheter-directed thrombolysis with the Endowave system.

Embolotherapy for pelvic congestion syndrome: long-term results.

Purpose: To evaluate the long-term clinical outcome of transcatheter embolotherapy in women with chronic pelvic pain caused by ovarian and pelvic varices.

Materials And Methods: The study population included consecutive patients referred to a tertiary-care interventional radiology service from 1998 to 2003 because of a high degree of clinical suspicion of pelvic and ovarian varices. Visual analog scales and questionnaires during clinic visits were used to measure pain perception levels.

Intravascular bullet migration: a report of two cases.

In the trauma setting, penetrating vascular injuries secondary to gunshot wounds need to be addressed promptly and carefully. By identifying the entry and exit sites, the pathway of injury can usually be determined. Vessel injury is typically related to direct vascular trauma or secondary blast injury.

Percutaneous management of bile duct strictures and injuries associated with laparoscopic cholecystectomy: a decade of experience.

Background: The 1990s were associated with a dramatic increase in bile duct injuries with the widespread use of laparoscopic cholecystectomy (LC). Interventional radiology has an integral role in diagnosing and managing these injuries. Definitive percutaneous management with balloon dilatation might be possible in select patients with intact biliary-enteric continuity, but longterm data are limited.
