A Multicenter Study of Needle Size and Safety for Splenic Biopsy.

Background Splenic biopsy is rarely performed because of the perceived risk of hemorrhagic complications. Purpose To evaluate the safety of large bore (≥18 gauge) image-guided splenic biopsy. Materials and Methods This retrospective study included consecutive adult patients who underwent US- or CT-guided splenic biopsy between March 2001 and March 2022 at eight academic institutions in the United States.

Caval pseudoaneurysms following complex inferior vena cava filter removal: Clinical significance and patient outcomes.

Objectives: To investigate the incidence and clinical significance of caval pseudoaneurysm and extravasation post-complex inferior vena cava filter retrieval.

Methods: A total of 83 patients (70% female, average age 56) underwent complex inferior vena cava filter retrieval between January 2015 and December 2019 utilizing either rigid endobronchial forceps ( = 69, 83%) and/or excimer laser ( = 20, 24%). Procedural variables were recorded.

Revascularization for failed carotid artery stenting in a patient with a rare vertebral artery anomaly.

There is a growing cohort of patients requiring complex revascularization for failed carotid artery stenting. This revascularization can be complex in patients with coexisting supra-aortic vascular anomalies. Aberrant origin of the vertebral artery (VA) is an example of such an anomaly.

Retrieval of a permanent VenaTech LGM filter 18 years after implantation using a novel removal method.

The VenaTech LGM (B. Braun, Melsungen, Germany) inferior vena cava (IVC) filter was designed as a permanent IVC filter to prevent clot migration and pulmonary embolism. This filter has been discontinued, but thousands remain implanted within patients who incur the added long-term risks of an indwelling IVC filter.
