Endoscopic third ventriculostomy for hydrocephalus accompanied by dural arteriovenous fistulae: a case report and literature review.

A 54-year-old man presented with gait disturbances, urinary incontinence, and headache for 6 months. Head computed tomography indicated several high-density mass lesions in the quadrigeminal cistern, causing occlusive hydrocephalus. Digital subtraction angiography confirmed tentorial dural arteriovenous fistulae (AVF).

Background: Free functional muscle transfer (FFMT) for brachial plexus injury (BPI) requires adequate donor arterial flow for successful anastomosis. However, concomitant BPI and subclavian artery injury are not uncommon. Arteriovenous (AV) loop graft is one of the methods used to extend vessels to areas with vascular depletion.

Introduction: Chronic hand ischaemia may affect some haemodialysis patients with an arteriovenous fistula (AVF) or graft (AVG), a condition known as haemodialysis access-induced distal ischaemia (HAIDI). Duplex ultrasonography (DUS) can provide comprehensive insights into anatomical and perfusion properties, and measuring the hand acceleration time (HAT) has been demonstrated to be sensitive within the framework of chronic upper limb ischaemia.
Methods And Analysis: This single-centre, prospective cohort study will involve adult end-stage renal disease (ESRD) patients requiring either AVF or AVG for haemodialysis.
Neutrophil-to-lymphocyte ratio as a predictor for early mortality in older patients requiring hemodialysis; insights for hemodialysis access planning.

Introduction: The 2019 Kidney Disease Outcome Quality Initiative guidelines emphasize the importance of selecting dialysis based on the life expectancy of the patient. However, it is difficult to predict the life expectancy of a patient during arteriovenous fistula creation. We investigated whether neutrophil-to-lymphocyte, monocyte-to-lymphocyte, and platelet-to-lymphocyte ratios measured before dialysis could predict mortality.

Hemodialysis for chronic kidney disease (CKD) relies on vascular access (VA) devices, such as arteriovenous fistulas (AVF), grafts (AVG), or catheters, to maintain blood flow. Nonetheless, unpredictable progressive vascular stenosis due to neointimal formation or complete occlusion from acute thrombosis remains the primary cause of mature VA failure. Despite emergent surgical intervention efforts, the lack of a reliable early detection tool significantly reduces patient outcomes and survival rates.
