Purpose: We report our experience in using the superficial femoral vein to create hemodialysis (HD) arteriovenous (AV) fistulas. Surgery was performed on six patients (four female, two male). Indications for surgery included previous fistula loss, graft infection and exhaustion of typical shunt sites.
Methods: The femoral vein was evaluated preoperatively, by Doppler ultrasound, harvested by one long incision on the anteromedial surface of the thigh, followed by suction drainage. In four patients, harvested veins were transplanted in the arm between the brachial artery and axillar vein, followed by an end-to-side anastomosis. In two patients, the venous graft remained on the anterior surface of the thigh. In those patients, they were extended with either a piece of polytetrafluoroethylene (PTFE) graft or the saphenous vein.
Results: Follow-up ranged between 14 months and 2 yrs, ensuring proper dialysis. Two patients presented with complications, including lower leg swelling and axillary lymphorrhea, which subsided spontaneously.
Conclusions: We recommend this type of AV fistula, especially in difficult cases, where all other classical vascular approaches have been used. However, the procedure is time consuming and requires experience in vascular surgery.

Phlebolith is a term that refers to round-shaped calcified thrombi commonly located in the pelvic region. The occurrence of dense, linear calcifications or phlebolith-like formations within the soft tissues of the lower extremities, particularly in the superficial femoral, greater saphenous, or popliteal veins, is rare. This study presents the case of a 73-year-old woman who was being evaluated for postmenopausal bleeding.

Background And Purpose: Proximal protection devices, such as TransCarotid Artery Revascularization (TCAR, SilkRoad Medical, Sunnyvale), aim to yield better outcomes in carotid artery stenting (CAS) than distal protection devices by preventing plaque embolization to the brain. However, transfemoral catheters may not fully reverse flow from the external carotid artery (ECA) to the internal carotid artery (ICA). We assess a new balloon-sheath device, Femoral Flow Reversal Access for Carotid Artery Stenting (FFRACAS), for this purpose.

In an effort to mitigate or reverse the pathological progression of early-stage osteonecrosis of the femoral head (ONFH), this study employed a promising strategy that involves the sustained delivery of osteogenic factors to augment core decompression, facilitated by the use of composite hydrogels. Specifically, a hydrogel was synthesized by blending chitosan, Pluronic F-127, and tripolyphosphate, utilizing both ionic bonding and copolymer micelle cross-linking techniques. This hydrogel demonstrated exceptional biocompatibility, temperature responsiveness, pH-dependent biodegradation, and controlled release properties.

Objective: Intermittent pneumatic compression (IPC) is considered the standard of care for preventing venous thromboembolism (VTE) in the hospital setting. However, its widespread adoption after hospitalization has been limited due to its shortcomings in obstruction of venous valves and blood reflux. The objective of this study is to compare the effects of continuous graduated pneumatic compression (CGPC), a new device with a novel mechanism, and IPC on lower hemodynamics and the incidence of VTE in patients undergoing arthroplasty.

tRNA-derived fragments (tRFs) are a newly recognized class of small noncoding RNAs (sncRNAs) that play significant roles in various diseases. The Wnt pathway plays a key role in various physiological processes such as embryonic development, tissue renewal and regeneration. In the regulation of Wnt/β-catenin, Forkhead box k1(FOXK1), Frizzled class receptor 3 (FZD3), and Wnt5b can be targeted and inhibited by three tRFs: tRF3008A targets FOXK1 to inhibit colorectal cancer (CRC), 5'-tiRNAVal targets FZD3 to inhibit breast cancer (BrC), and tRF-22-8BWS7K092 targets Wnt5b to induce ferroptosis in lung cells.
