Other Mechanical Complications of Surgically Created Arteriovenous Fistula, Initial Encounter

Surgically created arteriovenous fistula (AVF) is a type of vascular access created for patients undergoing hemodialysis. This type of access is created by connecting an artery directly to a vein, allowing for easy access during dialysis treatments. While AVF is a highly effective method of vascular access, it is not without complications. One of the most common complications of AVF is mechanical complications.

Mechanical complications occur when there is a problem with the structure or function of the AVF. These problems can range from minor issues such as bleeding and bruising to more serious complications such as thrombosis and aneurysm formation.

1. Bleeding and hematoma formation: One of the most common mechanical complications of AVF is bleeding and hematoma formation at the site of the vascular access. This can occur due to trauma during the cannulation process or due to a puncture in the wall of the vessel.
2. Steal syndrome: Steal syndrome occurs when blood flow is diverted from the distal extremity due to a high-flow AVF. This can result in ischemia and other complications such as ulceration, gangrene, and even limb loss if left untreated.
3. Aneurysm formation: Aneurysm formation is another complication that can occur in AVF. This occurs when the wall of the vessel becomes weakened and bulges out, increasing the risk of rupture and bleeding.
4. Thrombosis: Thrombosis is the formation of a blood clot within the AVF, which can cause blockage and decrease blood flow to the dialysis machine.
5. Infection: Infection is a potential complication of any surgical procedure, including AVF. This can occur at the site of the vascular access and can lead to serious complications if left untreated.

If you have recently undergone AVF surgery, it is important to be aware of the potential mechanical complications that can occur. If you experience any of the above symptoms, it is important to seek medical attention immediately to prevent further complications.

In conclusion, other mechanical complications of surgically created arteriovenous fistula, initial encounter, can range from minor issues such as bleeding and hematoma formation to more serious complications such as aneurysm formation and thrombosis. It is important to be aware of these potential complications and seek medical attention if you experience any symptoms.
