We know that tight stenosis is the underlying reason for acute thrombosis in vast majority of the cases. Since the morbidity and mortality of these patients are directly related to the effectiveness of hemodialysis, treatment of the stenosis is of great importance.

Dilatation with percutaneous transluminal angioplasty is performed with catheters containing inflatable balloons of 3-16 mm in diameter and 2-16 cm in length for vessels of different sizes.

Pharmacological methods or mechanical methods or both can be used for the recanalization of thrombosed fistulas. Pharmacological methods use local infusion of thrombolytics.

Conventional graft surgery has been shown to be more effective and lasting more than the endovascular approach.

Immature fistulas are minimally invasive and endovascular intervention is generally preferred because the venous reserve is preserved.

Surgery and interventional radiology cooperation and correct intervention at the right time are crucial in prolonging the life span of hemodialysis patients. Keywords : Percutaneous transluminal angioplasty, stent, thrombectomy, vascular intervention, thrombosis
