Endovascular Treatment of TASC C and D Femoropopliteal Arterial Disease With Heparin-Bonded Covered Stents: The Impact of Distal Run-Off Vessels.

Introduction: In the last 2 decades, several studies in the literature evaluated the possible role of covered stents in the treatment of TransAtlantic Inter-Society Consensus (TASC) C and D femoropopliteal lesions but, despite the encouraging results, the employment of these devices was never included in clinical guidelines. The aim of this study is to evaluate the role of the technical aspects in patients with TASC C or D lesions that were treated with the GORE VIABAHN endoprosthesis and to elaborate a computerized method to objectively estimate the post-stent run-off and predict stent-graft failure.

Materials And Methods: In this monocentric retrospective study, we collected the patients who were treated in our department from December 2014 to May 2021.

The spectrum of computed tomography findings in blunt trauma of the subclavian/axillary artery: a pictorial essay.

Traumatic injuries of the subclavian and axillary arteries are uncommon but have high morbidity and mortality. In contrast to penetrating injuries, which are often lethal, blunt injuries present a wide and heterogeneous spectrum of imaging findings. If a vessel tear or transsection is a life-threatening circumstance, minor injuries might be overlooked in an emergency setting but could cause or aggravate the functional loss of a limb.

Endovascular Management of Iatrogenic Arterial Injuries after Orthopedic Surgery of the Lower Limb.

Purpose: To evaluate the safety and effectiveness of embolization, and to identify the contributory factors of failures in patients treated for iatrogenic arterial injuries after orthopedic surgery of the lower limb.

Materials And Methods: In this retrospective study, data from patients treated from December 2008 to March 2022 for an arterial injury due to orthopedic surgery of the lower limb were analyzed from a single center. Demographic, clinical, and procedure-related data were collected.

Contrast-enhanced CT and liver surface nodularity for the diagnosis of porto-sinusoidal vascular disorder: A case-control study.

Background And Aims: Porto-sinusoidal vascular disorder (PSVD) is a rare and commonly overlooked cause of portal hypertension. The interest of CT analysis, including quantification of liver surface nodularity (LSN) for PSVD diagnosis has not been established. This study aimed at assessing the performance of LSN and CT features for a PSVD diagnosis in patients with signs of portal hypertension.

CT-based liver surface nodularity for the detection of clinically significant portal hypertension: defining measurement quality criteria.

Purpose: To establish measurement quality criteria for the noninvasive assessment of clinically significant portal hypertension (CSPH) in patients with cirrhosis using CT-based liver surface nodularity (LSN) measurements.

Methods: Seventy-four consecutive patients with cirrhosis (mean 62 ± 13 years), including 30 with CSPH (41%), underwent CT and hepatic venous pressure gradient measurements. Three independent readers performed 15 LSN measurements/patient using dedicated software.
