A Safety and Feasibility Single-Arm Study of a Novel Catheter Thrombectomy Device for the Treatment of Pulmonary Embolism (ENGULF).

Background: Despite advances in therapy options, pulmonary embolism (PE) continues to carry a high risk of mortality and morbidity. Currently, therapeutic options are limited with only 2 US Food and Drug Administration-cleared catheter-based embolectomy devices approved for the treatment of intermediate-risk PE. The novel Hēlo PE thrombectomy catheter (Endovascular Engineering, Inc) has a flexible and collapsible funnel with an internal agitator for a dual mechanism of treatment for acute PE.

Improving Compliance with Preoperative Nasal Povidone-Iodine to Prevent Surgical Site Infection in Vascular and Neurosurgery Services in a Community Teaching Hospital.

Surgical site infections (SSI) remain a cause of morbidity, prolonged hospitalization, surgical readmission, and death. Nasal colonization with methicillin-resistant Staphylococcal aureus is a frequent cause of device-related SSI and nasal mupirocin has been used for prevention. More recently, povidone-iodine nasal swabs have become an alternative.

The Impact of Implementation of a Commercial Inferior Vena Cava Filter Database Program on Filter Retrieval versus Physician Tracking over a 9-Year Period: A Retrospective, Observational Study.

Purpose: To compare the impact of a commercial tracking database on inferior vena cava filter retrievals with that of physician tracking and no tracking.

Materials And Methods: From January 2013 to December 2021, 532 filters were placed at a single institution and followed in 3 phases: (a) Phase 1, pretracking (January 1, 2013, to February 28, 2015); (b) Phase 2, commercial database tracking (March 1, 2015, to June 30, 2019); and (c) Phase 3, commercial database tracking with separate tracking by an interventional radiologist (July 1, 2019, to December 31, 2021). Patients excluded from the commercial database due to human error served as a control group.

Evaluation of Primary Lymphedema with Intranodal Lymphangiography.

Purpose: There are limited existing data on the lymphatic anatomy of patients with primary lymphedema (LED), which is caused by aberrant development of lymphatic channels. In addition, there is a paucity of contemporary studies that use groin intranodal lymphangiography (IL) to evaluate LED anatomy. The purpose of this retrospective observational study was to better delineate the disease process and anatomy of primary LED using groin IL.

Association between Patient Experience Scores and Low Utilization of Hepatocellular Carcinoma Treatment in the United States: A Surveillance, Epidemiology, and End Results-Consumer Assessment of Healthcare Providers and Systems Analysis (SEER-CAHPS).

Purpose: To study the experiences of patients with hepatocellular carcinoma (HCC) contributing to treatment discrepancy in the United States.

Materials And Methods: Using Surveillance, Epidemiology, and End Results data from National Cancer Institute (NCI), Medicare (2002-2015) beneficiaries with HCC who completed a Consumer Assessment of Healthcare Providers and Systems (CAHPS) survey were included. Six CAHPS items (3 global scores: global care rating [GCR], primary doctor rating [PDR], and specialist rating [SR]; 3 composite scores: getting needed care [GNC], getting care quickly [GCQ], and doctor communication [DC]) assessed patient experience.

Angiography with cone-beam CT versus contrast-enhanced MRI for living donor transplant imaging: Is MRI enough?

The purpose of this study is to compare the subjective and objective quality and confidence between conventional angiography with cone-beam computed tomography (CBCT) and magnetic resonance imaging (MRI) for the preoperative evaluation of potential donors for living donor liver transplant. Seventeen patients undergoing preoperative donor evaluation for living donor liver transplantation that underwent angiography with CBCT and contrast-enhanced MRI for evaluation of hepatic vascular anatomy were included in the study. Four attending radiologists interpreted anonymized, randomized angiography with CBCT images and MRIs, rating the diagnostic quality and confidence of their interpretation (on a 3-point scale) for each element, as well as clinically relevant measurements.
