Evaluation of short-term and long-term complications after emergent internal iliac artery embolization in patients with pelvic trauma.
To assess the incidence of long- and short-term complications following internal iliac artery (IIA) embolization after blunt pelvic trauma. ⋯ IIA embolization is an important means of controlling pelvic arterial hemorrhage. There is no significant increase in the risk of most evaluated long- and short-term complications in trauma patients who underwent IIA embolization versus those who did not. However, IIA embolization is associated with a marginally significantly increased rate of buttock, thigh, or perineal paresthesia.

Replacement of inadvertently discontinued tunneled jugular high-flow central catheters with tract recannulation: technical results and outcome.
To determine the technical and clinical outcomes of recannulating the tracts of inadvertently discontinued high-flow tunneled internal jugular central venous catheters. ⋯ Recannulating tunneled high-flow jugular catheter tracts has a high technical success rate, particularly when they have fallen out less than 24 hours earlier and have a mature tract. The outcomes of recannulated catheters (ie, infection and function rates) are within the upper limit of results of de novo placement and over-the-wire exchange of catheters in the literature.

Repeat radiofrequency ablation for local progression of lung tumors: does it have a role in local tumor control?
To retrospectively evaluate the role of repeat radiofrequency (RF) ablation for local progression of lung tumors in local tumor control. ⋯ Repeat RF ablation improved the overall local control outcomes. In particular, it offered an opportunity to salvage tumors that had no risk factors but nevertheless progressed locally after the first RF ablation. Conversely, tumors with risk factors were not controlled sufficiently even after repeating the procedure.

MR imaging perfusion mismatch: a technique to verify successful targeting of liver tumors during transcatheter arterial chemoembolization.
To evaluate the combined use of transcatheter intraarterial perfusion (TRIP) magnetic resonance (MR) imaging and dynamic contrast-enhanced MR imaging to determine complete tumor targeting during transcatheter arterial chemoembolization (TACE) when performed within an integrated MR imaging-interventional radiology (IR) angiography suite. ⋯ Performing TACE in an MR imaging-IR suite can facilitate complete tumor targeting. By comparing perfusion images from TRIP and contrast-enhanced MR sequences, the operator gains confidence and can potentially obtain more selective catheter placement during TACE.

Direct percutaneous approach for endoluminal glue embolization of stomal varices.
The present report describes the authors' experience with direct endoluminal embolization for bleeding stomal varices. Between December 1998 and July 2006, seven patients with enterostomies, portal hypertension, and recurrent stomal variceal bleeding resistant to medical treatment were treated at a single institution. Ultrasonography was used to guide direct puncture of the varices. ⋯ One patient with hepatocellular carcinoma and complete portal thrombosis had three recurrences treated with the same technique, with clinical success. Three patients died at 3, 8, and 18 months without recurrence of bleeding. Although further evaluation is indicated, direct percutaneous embolization appears to be a potential alternative treatment for bleeding stomal varices.
