Background: A cerebral arteriovenous fistula is a rare neurovascular abnormality. It is very scarce when presenting with other cerebral arteriovenous malformations after embolization.

Method: We reported a case primarily presenting with cerebral arteriovenous fistula. When the fistula was embolized completely, de novo multiple dural arteriovenous fistulas and a small arteriovenous malformation occurred due to the hemodynamic change after the embolization. Embolization of parts of the fistulas for the second time led to an untreatable malformation which became curable. At the third time, the remaining fistula was cured.

Results: The mechanism of the dural arteriovenous fistula and treatment strategy were discussed.

Conclusion: Venous hypertension is the main factor causing a dural arteriovenous fistula. Embolization of the fistulas step by step is recommended.

Study Design: Systematic Review and Meta-analysis.

Objective: This study aims to compare the efficacy and safety of surgical and endovascular treatments for SDAVFs.

Summary Of Background Data: Spinal dural arteriovenous fistulas (SDAVFs) result from an abnormal connection between the radiculomeningeal artery and the radicular vein, leading to venous hypertension and potential neurological damage.

Introduction: Nicaragua is a Central American country with a high prevalence of patients with chronic kidney disease, particularly among young men. This is largely attributable to Mesoamerican nephropathy, a form of interstitial nephritis that predominantly affects young agricultural workers. While the majority of patients have access to chronic dialysis programs, a very small number have an option of receiving a renal transplant.

Cerebral proliferative angiopathy (CPA) is a rare subtype of cerebral arteriovenous malformation, characterized by unique angiographic features and clinical presentations. Although the clinical and angiographic characteristics of CPA have been well described, their impact on the surrounding tissues remains underexplored. Herein, we investigated the presence of calvarial thickening in patients with CPA, and discuss its potential pathogenesis.

Rationale: Temporary central venous catheters are commonly used for patients who require emergency hemodialysis. In rare instances, this procedure can result in a very serious complication known as arteriovenous fistula (AVF). Although some cases of femoral arteriovenous fistula have been reported previously in the literature; however, the incidence of iliac AVF precipitated by a hemodialysis catheter is exceedingly uncommon.
