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.

Comparative StudyMatched-pair analysis of endovascular versus open surgical repair of abdominal aortic aneurysms in young patients at low risk.
To compare clinical outcomes of endovascular and open aortic repair of abdominal aortic aneurysms (AAAs) in young patients at low risk. It was hypothesized that endovascular aneurysm repair (EVAR) compares favorably with open aneurysm repair (OAR) in these patients. ⋯ Results from this observational study indicate that EVAR offers a favorable alternative to OAR in young patients at low risk.

Biliary sequelae following radioembolization with Yttrium-90 microspheres.
Yttrium-90 (90Y) radioembolization has emerged as a promising and safe therapeutic modality for patients with hepatocellular carcinoma (HCC) or metastatic liver cancer. The present report describes biliary sequelae following intraarterial 90Y therapy in patients with HCC or liver metastases. ⋯ 90Y therapy in patients with HCC or metastatic disease to the liver is associated with an acceptable rate of biliary toxicities. Further studies assessing long-term biliary sequelae are warranted.
