Anatomy of Risk: Decoding the Predictors of Vascular Access Complications in Transcatheter Aortic Valve Replacement.
Catheter Cardiovasc Interv
December 2024
Department of Surgery, University of North Dakota School of Medicine and Health Sciences, Grand Forks, North Dakota, United States.
Background: Despite advancements in valve implantation devices, vascular access complications (VAC) remain a significant cause of morbidity and mortality for those undergoing transcatheter aortic valve replacement (TAVR). We describe pre-operative imaging analysis of the aortoiliac and femoral arterial beds using the TransAtlantic intersociety consensus (TASC) score, ilio-femoral tortuosity, and procedural characteristics to identify anatomic risk factors predictive of VAC in TAVR.
Methods: Consecutive patients undergoing TAVR from 2012 to 2022 at a single North Dakota hospital were retrospectively reviewed.
Combination of age-adjusted d-dimer, platelet distribution width and other factors predict preoperative deep venous thrombosis in elderly patients with femoral neck fracture.
BMC Surg
December 2024
Department of Vascular Surgery, the Third Hospital of Hebei Medical University, Shijiazhuang, 050051, Hebei, P.R. China.
Purpose: This retrospective cohort study aimed to identify factors associated with preoperative deep venous thrombosis (DVT) in elderly patients with femoral neck fractures, and to investigate whether combining these factors could improve the ability to predict DVT.
Method: Medical records and laboratory test results were reviewed patients presenting with a femoral neck fracture and receiving routine chemoprophylaxis for DVT between January 2020 and December 2023 in a tertiary referral, university-affiliated hospital. Preoperative DVT was confirmed by Doppler ultrasound or CT venography.
The effects of gabapentin and pregabalin on fracture healing: A histological, radiological, and biomechanical analysis.
Jt Dis Relat Surg
January 2025
Balıkesir Üniversitesi Tıp Fakültesi Ortopedi ve Travmatoloji Anabilim Dalı, 10185 Altıeylül, Balıkesir, Türkiye.
Objectives: This study evaluated the impact of different doses of gabapentin and pregabalin on fracture healing in a rat femoral shaft model, with histological, radiological, and biomechanical assessments.
Materials And Methods: Seventy male Wistar albino rats were divided into five groups: control, low-dose gabapentin (GBP-L, 300 mg/day), high-dose gabapentin (GBP-H, 3600 mg/day), low-dose pregabalin (PRG-L, 150 mg/day), and high-dose pregabalin (PRG-H, 600 mg/day), based on human equivalent doses. Bilateral femoral fractures were induced; the right femurs were prepared for radiological examination using microtomography, followed by histological analysis, whereas the left femurs were allocated for biomechanical testing.
Hepatectomy with Hepatic Vein Resection and Reconstruction Under Total Vascular Exclusion and Venous Drainage via a Venovenous Bypass: An Additional Approach for Complex Hepatectomies.
Ann Surg Oncol
December 2024
Hepato-Pancreato-Biliary Surgery and Liver Transplantation, Pôle des Pathologies Hépatiques et Digestives, Hôpital de Hautepierre-Hôpitaux Universitaires de Strasbourg, Université de Strasbourg, Strasbourg, France.
Background: Total vascular exclusion (TVE) with liver hypothermic perfusion under venovenous bypass (VVB) is usually needed to perform hepatectomy with Inferior vena cava and hepatic veins resection-reconstruction. An alternative technique is represented by liver resection under intermittent pedicular clamping, IVC total clamping and VVB, without cold perfusion and liver outflow drainage through the VVB. PATIENTS AND METHODS: The patient is a 60-year-old woman with past medical history of right hepatectomy for leiomyosarcoma 14 years previously.

World J Exp Med
December 2024
Department of Radiology, University of Texas Southwestern Medical Center, Dallas, TX 75235, United States.
Background: Hip dysplasia (HD) is characterized by insufficient acetabular coverage of the femoral head, leading to a predisposition for osteoarthritis. While radiographic measurements such as the lateral center edge angle (LCEA) and Tönnis angle are essential in evaluating HD severity, patient-reported outcome measures (PROMs) offer insights into the subjective health impact on patients.
Aim: To investigate the correlations between machine-learning automated and manual radiographic measurements of HD and PROMs with the hypothesis that artificial intelligence (AI)-generated HD measurements indicating less severe dysplasia correlate with better PROMs.
