We aimed to demonstrate the complications of carotid-cavernous fistula (CCF) and their correlation with venous hypertension. From August 2000 to April 2008 we performed more than 2400 catheter angiographic procedures. Among those, six unusual cases presented acute complications of CCF. The presented complications of CCF from our cases showed a possible correlation with venous hypertension. With the experiences from our cases, venous hypertension may complicate CCF with a poor prognosis. The condition should be carefully evaluated and if present prompt treatment is necessary.
