Feasibility of Artificial Intelligence Powered Adverse Event Analysis: Using a Large Language Model to Analyze Microwave Ablation Malfunction Data.

Determine if a large language model (LLM, GPT-4) can label and consolidate and analyze interventional radiology (IR) microwave ablation device safety event data into meaningful summaries similar to humans. Microwave ablation safety data from January 1, 2011 to October 31, 2023 were collected and type of failure was categorized by human readers. Using GPT-4 and iterative prompt development, the data were classified.

Comparing prostatic artery embolization to surgical and minimally invasive procedures for the treatment of benign prostatic hyperplasia: a systematic review and meta-analysis.

Background: To summarize current evidence to report a comparative systematic review and meta-analysis of prostatic artery embolization (PAE) with transurethral resection of the prostate (TURP) and open simple prostatectomy (OSP) for the treatment of benign prostatic hyperplasia (BPH).

Methods: A systematic literature search was performed to identify studies published from inception until August 2021. The search terms used were (prostate embolization OR prostatic embolization) AND (prostatic hyperplasia OR prostatic obstruction) as well as the abbreviations of PAE and BPH.

Randomized Controlled Trial of Percutaneous Radiologic Gastrostomy Performed With and Without Gastropexy: Technical Success, Patient-Reported Outcomes and Safety.

Purpose: The aim of this study is to compare balloon-retention percutaneous radiologic gastrostomy (PRG) tube insertion performed with and without gastropexy, primarily focusing on pain and patient-reported outcomes.

Materials And Methods: Research ethics board approved a dual-arm, single-centre, randomized trial of 60 patients undergoing primary 14-French PRG tube insertion (NCT04107974). Patients were randomized to receive either PRG with gastropexy or without gastropexy.

Peripherally Inserted Central Catheters (PICCs) at the Bedside by X-ray Technologists: A Review of Our Experience.

Introduction: Peripherally inserted central catheters, also known as PICC lines, are very common procedures for patients in the hospital who need to have long-term intravenous access, for various reasons such as antibiotics or total parenteral nutrition. At our institution, there is currently only one interventional radiology (IR) suite in our department to accommodate all IR procedures. Therefore, the bedside PICC program was introduced to help alleviate the workload in the IR suite and to improve overall patient care.

Initial Canadian Experience of Prostate Artery Embolization for Symptomatic Benign Prostatic Hyperplasia: Midterm Outcomes.

Introduction: This study aimed to assess the midterm outcomes and safety of prostate artery embolization (PAE) for the treatment of benign prostatic hyperplasia (BPH).

Methods: A single-center, retrospective review of PAE performed for BPH was performed. Validated International Prostate Symptom Score (IPSS), quality of life (QoL) index, and International Index for Erectile Function (IIEF-5) questionnaires were completed at baseline and at least 12 months post-procedure.

Initial Experience With Viabahn VBX as the Bridging Stent Graft for Branched and Fenestrated Endovascular Aneurysm Repair.

Purpose: To evaluate the feasibility and safety of a novel balloon-expandable, heparin-bonded endoprosthesis (Viabahn VBX, W. L. Gore and Associates) when used as a bridging stent graft (BSG) with fenestrated and branched endovascular aneurysm repair (FB-EVAR).

Portal Vein Embolization: Correlation of Future Liver Remnant Hypertrophy to Type of Embolic Agent Used.

Purpose: The purpose of this study was to compare the effectiveness of portal vein embolization (PVE) with different embolic agents used at our centre. Specifically, the effectiveness of N-butyl cyanoacrylate (NBCA) glue is compared with that of polyvinyl alcohol (PVA) particles.

Methods: We performed a retrospective chart review of all patients (N = 77) who underwent PVE at our institution over a 5-year period.

Percutaneous Recanalization of Iliac Artery Occlusions by Radiofrequency Perforation: Initial Experience.

The success rate of endovascular therapy for iliac occlusions is often limited by failure to traverse the lesion. A single institution's experience with the use of radiofrequency-assisted recanalization of occlusions in 10 iliac arteries is described. The median length of occlusion was 43 mm (range, 14-64 mm; mean, 42 mm).

AMPLATZER Vascular Plug 4 for proximal splenic artery embolization in blunt trauma.

A consecutive case series was conducted evaluating proximal splenic artery embolization (SAE) with the AMPLATZER Vascular Plug 4 (AVP4) (St. Jude Medical, Inc, St. Paul, Minnesota) in eight patients with high-grade splenic trauma.

Radiofrequency guide wire recanalization of venous occlusions in patients with malignant superior vena cava syndrome.

Fibrotic central venous occlusions in patients with thoracic malignancy and prior radiotherapy can be impassable with standard catheters and wires, including the trailing or stiff end of a hydrophilic wire. We report two patients with superior vena cava syndrome in whom we successfully utilized a radiofrequency guide wire (PowerWire, Baylis Medical, Montreal, Quebec, Canada) to perforate through the occlusion and recanalize the occluded segment to alleviate symptoms.

Endograft collapse following endovascular repair of traumatic aortic injury.

The advent of endovascular treatment of traumatic thoracic aortic injuries offers a valuable, minimally invasive alternative to open surgical repair. However, there are limitations of the current endovascular stent graft technology for this group of patients. After endovascular repair meticulous follow-up is required with a high index of suspicion for potential complications including the lethal complication of endograft collapse.

Critical lower-limb ischemia: the diagnostic performance of dual-phase injection MR angiography (including high-resolution distal imaging) compared with digital subtraction angiography.

Purpose: To prospectively compare contrast-enhanced (CE) magnetic resonance (MR) angiography against digital subtraction angiography (DSA) in patients with critical lower-limb ischemia.

Materials And Methods: Thirty patients with critical lower limb ischemia underwent both CE MR angiography and DSA. CE MR angiography commenced with a dedicated high-resolution study of the below-knee arteries followed by a three-station bolus-chase examination.
