Radiofrequency guidewire-facilitated recanalization of chronic thoracic central venous occlusions in hemodialysis patients.

Purpose: To assess the outcome and safety of radiofrequency (RF) wire recanalization in patients with end-stage renal disease (ESRD) and chronic central venous occlusions (CVO).

Materials And Methods: A retrospective review of ESRD patients who underwent RF-wire recanalization of symptomatic chronic thoracic CVO from January 2017 to August 2022 yielded 20 patients who underwent 21 procedures. All patients had undergone at least one prior unsuccessful attempt at central venous recanalization using conventional catheter-based techniques.

Endovascular Management of Neurofibromatosis Type I-Associated Vasculopathy: A Case Series and Brief Review of the Literature.

Purpose: Neurofibromatosis type 1 (NF1) is an autosomal-dominant disorder found in approximately 1 of every 3000 individuals. Neurofibromatosis type 1 can have vascular manifestations including aneurysms, stenoses, and arteriovenous malformations. The purpose of this article is to describe the clinical manifestations of NF1 vasculopathy, discuss therapeutic options, and highlight endovascular therapies from our institutional experience.

Survival Outcomes of Very Small Drug-Eluting Beads Used in Chemoembolization of Unresectable Hepatocellular Carcinoma.

Purpose: To assess the safety and efficacy of transarterial chemoembolization using a 75-μm drug-eluting embolic (DEE) in patients with unresectable hepatocellular carcinoma (HCC).

Materials And Methods: The medical records of 109 patients with a mean age of 64.1 years (range 85-49) treated for unresectable HCC between November 2013 and August 2016 with transarterial chemoembolization using a 75-μm DEE were retrospectively reviewed.

Infection of Small-Bore Tunneled Central Venous Catheters.

The purpose of this study is to evaluate the association of common clinical variables with small-bore tunneled central venous catheter (CVC) infection. Retrospective data were collected from all small-bore (6-French) tunneled CVCs placed by the interventional radiology service between 2012 and 2015. Only patients who had a documented reason for tunneled CVC removal were included in the analysis to capture all events.

Accidental Concentrated Hydrogen Peroxide Ingestion Associated with Portal Venous Gas.

A case of a 52-year old male patient who presented to the emergency department with severe nausea and vomiting following accidental ingestion of H2O2. A computed tomography (CT) abdomen performed at our institution demonstrated extensive portal venous gas throughout the liver with few gas droplets seen in the extrahepatic portal vein portion. Pneumatosis was also noted in the wall of the gastric antrum.

Outcomes of fluoroscopic and ultrasound-guided placement versus laparoscopic placement of peritoneal dialysis catheters.

Background: Several peritoneal dialysis catheter (PDC) placement techniques have been described. The objective of this study was to compare the fluoroscopy and ultrasound guidance technique with the laparoscopic technique.

Methods: We retrospectively reviewed the medical records of 260 patients who had their first PDC placed between January 2005 and June 2016.

Approaches for safe transarterial chemoembolization of multifocal hepatocellular carcinoma with retrograde flow in a retroportal artery.

We report a case of an 81-year-old woman with multifocal hepatocellular carcinoma who underwent transarterial chemoembolization. The patient had significant superior mesenteric artery (SMA) ostial stenosis, which led to retrograde flow in the retroportal artery to the SMA. The authors adopted several approaches to avoid potential nontarget embolization that might result from the change in the hemodynamics in the hepatoenteric arteries by initially stenting the SMA ostial stenosis as well as the use of the Surefire infusion system and balloon occlusion for delivery of chemoembolization material to tumors in the hepatic lobes.

Percutaneous embolization of cystic duct stump leak following failed endoscopic management.

A case of a 79-year-old man, status post laparoscopic cholecystectomy with a drainage catheter placed at the gallbladder fossa is presented. The case was complicated postoperatively by abdominal pain and bilious discharge from the drainage catheter. Endoscopic retrograde cholangio-pancreatography demonstrated leakage through the cystic duct stump into the gallbladder fossa.

Embolization of congenital intercostobronchial trunk-pulmonary artery fistula using Amplatzer vascular plugs.

We present the case of a 54-year-old male patient diagnosed with a right upper lobe lung cancer and was referred for resection. Positron emission tomography-computed tomography scan showed a prominent vascular structure in the right lung, suspicious for vascular malformation. A computed tomography angiography was done, demonstrating an intercostobronchial trunk-pulmonary artery fistula.

Erratum: Outcomes of fluoroscopic and ultrasound-guided placement versus laparoscopic placement of peritoneal dialysis catheters.

Persistent Pulmonary Arteriovenous Malformations: Percutaneous Embolotherapy.

Pulmonary arteriovenous malformations (PAVM) are an uncommon entity that interventional radiologists may face in their clinical practice. Many of these lesions are treated successfully using endovascular techniques with satisfactory long-term results. However, some PAVMs respond poorly to initial interventional techniques.
