Portal hypertension increases the risk of hepatic decompensation after 90Yttrium radioembolization in patients with hepatocellular carcinoma: a cohort study.

Background: Transarterial radioembolization (TARE) is increasingly used in patients with hepatocellular carcinoma (HCC). This treatment can induce or impair portal hypertension, leading to hepatic decompensation. TARE also promotes changes in liver and spleen volumes that may modify therapeutic decisions and outcomes after therapy.

Maximum tumor-absorbed dose measured by voxel-based multicompartmental dosimetry as a response predictor in yttrium-90 radiation segmentectomy for hepatocellular carcinoma.

Objective: Advances in hepatic radioembolization are based on a selective approach with radical intent and the use of multicompartment dosimetric analysis. The objective of this study is to assess the utility of voxel-based dosimetry in the quantification of actual absorbed doses in radiation segmentectomy procedures and to establish cutoff values predictive of response.

Methods: Ambispective study in hepatocarcinoma patients treated with radiation segmentectomy.

Uterine Artery Embolization of Uterine Arteriovenous Malformation: A Systematic Review of Success Rate, Complications, and Posterior Pregnancy Outcomes.

Uterine Arteriovenous Malformation (UAVM) is a rare but life-threating cause of uterine bleeding. The clinical management of this condition is challenging, and there is a need to describe the most adequate approach for these patients. Uterine artery embolization (UAE) is the most widely-published treatment in the literature in recent years, although there is a need to update the evidence on this treatment and to compare it with other available therapies.

Point-of-care manufacturing: a single university hospital's initial experience.

Background: The integration of 3D printing technology in hospitals is evolving toward production models such as point-of-care manufacturing. This study aims to present the results of the integration of 3D printing technology in a manufacturing university hospital.

Methods: Observational, descriptive, retrospective, and monocentric study of 907 instances of 3D printing from November 2015 to March 2020.

Pelvic fractures with associated retroperitoneal hematoma: time until angioembolization and results.

Introduction: Two areas of controversy in the management of bleeding pelvic fractures are the need to perform angioembolization (AE) in patients with a retroperitoneal hematoma (RPH) but no contrast extravasation (CE) on Computerized Tomography (CT) and/or angiography, and the delay to AE. Our main objective was to assess whether there had been differences in the percentage and delay to AE between patients admitted on weekdays versus off-hours (weekends and admission after 3pm) at our hospital. Our hypothesis was that angiography and AE would be more frequent on weekdays, and the time delay would be longer during off-hours, with a higher mortality in this latter group for a similar overall severity.

[Intense urethrorrhagia after retropubic radical prostatectomy with selective embolization of the internal pudendal artery.].

Objective: Urethrorrhagia after radicalprostatectomy(RP) is very uncommon, regardless of the surgicalapproach used. Arterio-urethral fistula formation betweeninternal pudendal artery branches(IPA) and bulbarurethra is an exceptional finding.

Methods: We report what we consider the first series oftwo cases (one has already been published) of urethrorrhagiaafter open retropubic RP due to urethrovascular fistulaformation with its origin in the IPA or in one of its terminalbranches.

Embolization through the thyrocervical trunk: vascular anatomy, variants, and a case series.

Background And Purpose: The thyrocervical trunk (TCT) is the second ascending branch of the subclavian artery. It is considered a 'border territory' between interventional vascular radiology and interventional neuroradiology because it gives rise to branches both cervical and to the upper limbs. We describe the TCT branches anatomy, the most frequent variants, and expose eight endovascular procedures performed through the thyrocervical trunk.
