JOURNAL OF VASCULAR AND INTERVENTIONAL RADIOLOGY. Postinterventional Passive Expansion of Partially Dilated Transjugular Intrahepatic Portosystemic Shunt Stents

Claus Christian Pieper, MD , Alois Martin Sprinkart, MSc , Jennifer Nadal, MSc , Valerie Hippe, MD , Carsten Meyer, MD , Hans Heinz Schild, MD , Daniel Thomas, MD

JOURNAL OF VASCULAR AND INTERVENTIONAL RADIOLOGY. Transjugular Intrahepatic Portosystemic Shunt Endografts: A Decade in and Due for Revision?

Ziv J Haskal, MD

The articles by Gaba et al (1) and Pieper et al (2) describe the inevitable expansion of the VIATORR (W. L. Gore & Associates, Flagstaff, Arizona) endograft and bare metal stents within the transjugular intrahepatic portosystemic shunt (TIPS) tract regardless of their underdilation at placement. Both studies used quantitative analyses of incidentally obtained computed tomography scans of patients receiving a TIPS to show that the minimum outer stent diameter expands over time to that stent’s nominal size and cross-sectional area.

JOURNAL OF VASCULAR AND INTERVENTIONAL RADIOLOGY. Preoperative Embolization in Surgical Treatment of Spinal Metastases: Single-Blind, Randomized Controlled Clinical Trial of Efficacy in Decreasing Intraoperative Blood Loss

Caroline Clausen, MD , Benny Dahl, MD, PhD, DMSc , Susanne C. Frevert, MD , Lars V. Hansen, MD , Michael Bachmann Nielsen, MD, PhD, DMSc , Lars Lönn, MD, PhD

Purpose: To assess whether preoperative transcatheter arterial embolization of spinal metastases reduces blood loss, the need for transfusion with allogeneic red blood cells (RBCs), and surgery time in the surgical treatment of patients with symptomatic metastatic spinal cord compression.

JOURNAL OF VASCULAR AND INTERVENTIONAL RADIOLOGY. Automatic Three-Dimensional Detection of Prostatic Arteries Using Cone-Beam CT during Prostatic Arterial Embolization

Mélanie Chiaradia, MD , Alessandro Radaelli, PhD , Alexandre Campeggi, MD , Mohamed Bouanane, MD , Alexandre De La Taille, MD, PhD , Hicham Kobeiter, MD

The purpose of this study was to evaluate the automatic three-dimensional detection of prostatic arteries (PAs) with the use of dual-phase cone-beam computed tomography (CT) imaging and vessel-tracking software during prostatic artery (PA) embolization (PAE). In six patients, six right PAs and five left PAs were detected by using the software (sensitivity, 92%). The false-positive arteries (right side, 14%; left side, 25%) were deleted after cone-beam CT review. Automatic software detection of PAs from cone-beam CT may permit identification of the PA during PAE.
