Tunneled femoral dialysis catheters and factors affecting their outcome: a single institution experience.

Background: To assess a single-center experience with tunneled femoral dialysis catheter usage and outcomes and to identify any operator-dependent factors related to risk of premature catheter failure.

Methods: Retrospective review of the institutional radiology information system for tunneled femoral dialysis catheter placement from 2010 to 2017 was performed. Patients for whom the catheter was placed for an indication other than dialysis or who were less than 18 years of age at the time of catheter placement were excluded.

Outcomes after successful fallopian tube recanalization: A single institution experience: Observational Retrospective study.

Purpose: To determine outcomes after successful fallopian tube recanalization (FTR) in women who suffer infertility with documented tubal occlusion on hysterosalpingogram.

Methods: A retrospective review of consecutive successful FTR procedures from January 2010 to December 2016 was performed. 53 women who had hysterosalpingogram confirmed unilateral or bilateral tubal occlusion from a single tertiary academic medical center and successful FTR were eligible for inclusion.

Percutaneous Cholecystolithotomy Using Cholecystoscopy.

The morbidity and mortality of cholecystectomy can increase to 10% in high surgical risk patients. The technique for percutaneous cholecystolithotomy consists of 3 steps: (1) percutaneous cholecystostomy, (2) tract dilation and cholecystolithotomy, and (3) tract evaluation and catheter removal. Cholecystoscopy is critical in guiding the lithotripsy probe for fragmentation of large stones and is useful for locating small stone fragments not seen in cholangiography.

Modified Balloon-Occluded Retrograde Transvenous Obliteration (BRTO) Techniques for the Treatment of Gastric Varices: Vascular Plug-Assisted Retrograde Transvenous Obliteration (PARTO)/Coil-Assisted Retrograde Transvenous Obliteration (CARTO)/Balloon-Occluded Antegrade Transvenous Obliteration (BATO).

Gastric varices in the setting of portal hypertension occur less frequently than esophageal varices but occur at lower portal pressures and are associated with more massive bleeding events and higher mortality rate. Balloon-occluded retrograde transvenous obliteration (BRTO) of gastric varices has been well documented as an effective therapy for portal hypertensive gastric varices. However, BRTO requires lengthy, higher-level post-procedural monitoring and can have complications related to balloon rupture and adverse effects of sclerosing agents.

Assessment of the Albumin-Bilirubin (ALBI) Grade as a Prognostic Indicator for Hepatocellular Carcinoma Patients Treated With Radioembolization.

Objective: As the utility of Child-Pugh (C-P) class is limited by the subjectivity of ascites and encephalopathy, we evaluated a previously established objective method, the albumin-bilirubin (ALBI) grade, as a prognosticator for yttrium-90 radioembolization (RE) treatment for patients with hepatocellular carcinoma (HCC).

Materials And Methods: A total of 117 patients who received RE for HCC from 2 academic centers were reviewed and stratified by ALBI grade, C-P class, and Barcelona Clinic Liver Cancer stage. The overall survival (OS) according to these 3 criteria was evaluated by Kaplan-Meier survival analysis.

The role of interventional radiology in urologic tract trauma.

The kidney is the third most common abdominal organ to be injured in trauma, following the spleen and liver, respectively. Several classification systems convey the severity of injury to kidneys, ureter, bladder, and urethra. The most commonly used classification scheme is the American Association for the Surgery of Trauma (AAST) classification of blunt renal injuries, which grades renal injury according the size of laceration and its proximity to the renal hilum.

Uteroenteric fistula after uterine artery embolization.

Background: Uterine artery embolization is a common procedure for symptomatic leiomyomas and is being used as a less invasive alternative to a hysterectomy. This is a report of an uteroenteric fistula after uterine artery embolization.

Case: A 50-year-old woman developed an uteroenteric fistula that was seen on a computed tomography scan 6 months after she had an uncomplicated uterine artery embolization for symptomatic leiomyomas.

New parameter of hemoglobin status as an indicator of efficacy of preoperative angioembolization in extracranial hypervascular tumours.

Background: Routinely, the standard for measuring the success of preoperative embolization procedure as an adjunct in the management of head and neck vascular tumours has been to evaluate the amount of blood loss, duration of surgery, and intraoperative neurovascular injuries.

Objective: We hypothesized that the rate of change in the preoperative hemoglobin status would more accurately and objectively reflect the effectiveness of the embolization technique.

Materials And Methods: Twenty-six patients with extracranial vascular tumours were divided into two groups (A and B) of 13.
