The liver twist: A case of accessory liver lobe torsion presenting after mild trauma.

An accessory liver lobe is a congenital anomaly of hepatic tissue most commonly due to embryonic heteroplasia. Rarely, accessory liver lobes can undergo torsion and present as an acute surgical emergency. Although common in certain animals, there are only a few reported cases of accessory lobe torsion in humans.

Fractured Bard Recovery, G2, and G2 express inferior vena cava filters: incidence, clinical consequences, and outcomes of removal attempts.

Purpose: To increase the understanding of risks of inferior vena cava (IVC) filter fracture and embolization and the safety of removing fractured filters via retrospective review of a prospectively collected database of fractured IVC filters.

Materials And Methods: A total of 63 fractured IVC filters were discovered among 548 patients presenting for retrievable filter removal between April 2004 and November 2010 at a single institution. Device type, duration of implantation, component fracture, and embolization events were recorded.
