Dual-balloon infusion microcatheter for selective drug-eluting bead transarterial chemoembolization: initial feasibility study.

Purpose: We aimed to demonstrate feasibility of the use of a dual-balloon infusion microcatheter for segmental/subsegmental drug-eluting bead transarterial chemoembolization (DEB-TACE).

Methods: Over a 16-month period, 15 segmental and 21 subsegmental DEB-TACE procedures were attempted using a dual-balloon anti-reflux microcatheter (IsoFlow™ microcatheter, Vascular Designs Inc.) in 21 patients (15 males; median age, 61 years; range, 49-82 years) with hepatocellular carcinoma (Barcelona clinic liver cancer stage A [n=4]; B [n=12]; C [n=5]) with one to three tumors, median size of 3.

Transcatheter treatment of liver laceration from blunt trauma.

Blunt hepatic trauma is a fairly common pathology seen in trauma centers. We describe a pediatric patient who suffered blunt hepatic trauma that was managed successfully with a combination of exploratory laparotomy and liver packing, followed by hepatic artery embolization by interventional radiology (IR) after he continued to have significant arterial extravasation. Also discussed are trends in overall blunt hepatic trauma management and the technique of IR management.

Bullet embolization: multidisciplinary approach by interventional radiology and surgery.

Bullet embolization after penetrating trauma is an infrequent but important phenomenon. It presents an unexpected sequelae to the otherwise predictable injury pattern of penetrating missile injury mechanism and poses a challenging diagnostic and therapeutic dilemma. Bullets from penetrating wounds can gain access to the vasculature and migrate to nearly every large vascular bed.

Multidisciplinary management of blunt pelvic trauma.

Pelvic fractures account for ∼3% of all fractures and usually occur in patients with polytrauma. Pelvic fractures usually indicate high energy transfer and a significant mechanism of injury, and they can involve massive hemorrhage. For this reason, mortality from pelvic trauma is high, ranging from 40% to 60% among patients in shock, and up to 90% in patients considered to be in extremis.
