ABSTRACT
This paper reported the method of the subclinoid part of the internal carotid artery break in to sphenoidal sinus. Materials and Methods: The 3 cases suffered from parabasal fractures of the skull during head trauma. The false aneurysm of the subclinoid part of the internal carotid artery broke into sphenoidal sinus and caused fatal nasal hemorrhages. Selective internal carotid arteriographies were made through femoral artery, approach. BALTs were put into the ruptured places of the arteries after di agnoses were confirmed. Results: In the above cases the internal carotid arteries were occluded and profuse nasal hemorrhages stopped and did not appear again in the follow up period (6 months-3 years) . Conclusion: The method presented in the paper is a simple, safe and reliable one for the treatment of profuse nasal bleeding caused by parabasal fractures of the skull.
