Three cases of direct arteriovenous fistulas of the scalp (two involving cirsoid aneurysms) are presented. All three patients were treated with direct puncture of the venous pouch and injection of absolute ethyl alcohol during compression of the venous outflow of the fistula. Two of the three patients were cured with this treatment alone. The third patient, with a very high-flow giant fistula, required injection of glue to close the fistula and subsequent surgical extirpation of the resulting hard mass lesion.

Central venous catheters (CVCs) are commonly used for multiple clinical purposes. The internal jugular vein (IJV) is preferred among the most frequently used insertion sites due to its higher success rates and lower complication risks. Although CVC placement is generally considered a safe procedure, several complications have been reported.

Objective: As radiocephalic fistula is not necessarily appropriate for all patients with advanced kidney disease, our aim was to investigate the sensitive indicators that affect the functional primary patency of radiocephalic fistulas.
Methods: This prospective observational study included consecutive patients referred to the Second Hospital of Dalian Medical University for initial creation of radiocephalic fistula from July 2017 to December 2019. Preoperative ultrasound parameters, demographic characteristics, serum indicators and comorbidities were recorded.

Spinal arteriovenous(AV) shunt disease is rare, although many neurosurgeons may encounter patients with the disease. Recently, the pathological findings and classification of spinal AV shunt disease have been well described. The fundamental treatment of spinal AV shunt disease involves interruption of the shunt, which is achieved by endovascular treatment or direct surgery.

Background: Arteriovenous (AV) fistulas are the preferred access for dialysis but have a high incidence of failure. This study aims to understand the crosstalk between skeletal muscle catabolism and AV fistula maturation failure.
Methods: Skeletal muscle metabolism and AV fistula maturation were evaluated in mice with chronic kidney disease (CKD).
