Real-World Evaluation of the Off-the-Shelf Precannulated Inner-Branched Endograft for Pararenal Aortic Aneurysms.

Purpose: To analyze the early performance and efficacy of the first commercially available off-the-shelf precannulated multibranched endograft in the endovascular repair of pararenal abdominal aortic aneurysms (PAAAs). The device received European marketing approval in late 2020.

Materials And Methods: Between January 2021 and June 2023, a retrospective analysis of prospectively collected data from all consecutive patients with pAAAs undergoing implantation of the E-nside precannulated inner-branched endograft was conducted in 2 centers.

Needle tract seeding and abdominal recurrence following pre-treatment biopsy of gastrointestinal stromal tumors (GIST): results of a systematic review.

Background: Gastrointestinal stromal tumors (GIST) are rare abdominal tumors. Pretreatment biopsies may be used to diagnose a GIST and enable tailored treatment. Some experts are skeptical about biopsies because they fear tumor cell seeding.

Medium term outcome of Lancaster cortical window technique for extraction of femoral stem in revision hip arthroplasty.

Background: The extraction of a femoral stem during the revision hip arthroplasty can be a daunting task and can lead to catastrophic complications for the patient. A sound technique employed intraoperatively helps in the speedy recovery of the patient and reduces the risk of future surgical interventions. In this study, we present a medium-term outcome of our novel Lancaster cortical window technique which can be used for the removal of cemented or uncemented femoral stems.

Hepatic epithelioid hemangioendothelioma and the danger of misdiagnosis: report of a case.

Malignant hepatic epithelioid hemangioendothelioma (HEHE) is a rare malignant tumor of vascular origin. Nonspecific symptoms and the absence of experience of surgeons, radiologists, and histopathologists due to the rarity of HEHE make the diagnosis of this entity very challenging. Misdiagnosis is not a rare event, and the consequences of such an event are catastrophic.

Comparison of second-generation stents for application in the superficial femoral artery: an in vitro evaluation focusing on stent design.

Purpose: To examine and compare in an ex vivo study different nitinol stent designs intended for the superficial femoral artery (SFA) with regard to the appearance of fracture.

Methods: Seven different 8-×40-mm nitinol stents were evaluated (Misago, Absolute, Smart, Luminexx, Sentinol, Lifestent NT, and Sinus-Superflex). Finite element analysis (FEA) was used for digitalized stent design comparison; the strain during stent movement was calculated for bending, compression, and torsion.
