What symptom does cerebral arteriovenous fistula have

summary

Cerebral arteriovenous fistula is one of the most common diseases. Although it is not very serious, it should be treated in time. There is an abnormal channel between artery and vein, which is called arteriovenous fistula. Because the blood of the artery flows into the accompanying vein through the normal orifice, it can cause the local vascular lesions of the fistula and the hemodynamic changes of the local, peripheral circulation and systemic system of the fistula. Let's share some experience.

What symptom does cerebral arteriovenous fistula have

First, the diagnosis of AVF is not difficult. In the history of penetrating trauma, the patient can find pulsatile mass and local buzzing.

Second: swelling of one limb, varicose veins and venous valve insufficiency, local skin temperature of the limb higher than that of the contralateral, scar, murmur and tremor of the injured part.

Third, the diagnosis of AVF should be considered. Patients with acute arteriovenous fistula often have severe multiple trauma or penetrating injury. The diagnosis and management of AVF are often delayed due to the focus on the site of severe bone and soft tissue injury.

matters needing attention

Once arteriovenous fistulas are found, they can only be treated by operation. The arteriovenous fistulas can be removed by operation to prevent the rupture of arteriovenous fistulas.
