Objective To explore the feasibility and value of special carotid cavemous fistula(CCF). Metheds In 28 cases with traumatic history, cerebral angiographies were performed via percutaneous transfemoral route before endovascular embolization. Results Bilateral CCF in 6 cases,unilateral CCFs including mutileakage in 2 cases and small fistulae in 4 cases,CCF combined with fracture segment in 11 cases,traumatic aneurysms in 3 cases,NPPB after embolizationin 2 cases. The fistulas of 9 cases were occluded with patency of internal carotid artery(ICA),and ICA were occluded in 19cases.Conclusions Endovascular embolization of carotid cavernous fistula was safe and effective.This methed should be the first choice for the treatment.Different techniques of endovascular embolization should be undertaken for different CCF.

Abstract The 3H-thymidine (3H-TdR) incorporation rate of diploid human embryo lung fibroblast cell (2BS) in old cells was significantly lower than that in middle age cells and young cells. EPidermal growth factor (EGF) stimulated tha 3H-TdR incorporation rates of all three kinds of cells with different age. The results of Northern and dot hybridization showed that the level of HER-2 in old cells was lower than those in young cells. EGF could induce expression of HER-2 gene in young cells but not in old cells. As the cells reached 100% of their life span, the EGFR mRNA decreased obviously.

Objective To explore the treatment and efficiency of high blood flow vascular malformations of oral maxillofacial region with super-selective arterial embolization. Methods 18 cases underwent angiography of the head and neck before treatment and then followed by super-selective catheterization with microcatheter to embolize the feeding vessels of the vascular malformations with PVA. 8 cases underwent surgical excision within 72 hours after the embolization and the other 10 cases passed through the arterial radical emboliztion treatment. Results Technical success ratio reached 100% with no complications causing skin necrosis or incorrect arterial embolization else where in the skull. All 8 cases undergone preoperative embolization showed obviously less bleeding, easier removal of the mass and reduction of operation time. 10 cases with radical arterial embolization manifested reduction of swelling and improvement of organ function within 1 to 24 months after the procedure. 5 patients were cured with only once operation, 4 cases with twice operation and 1 with the thrice. Conclusions Aterial embolization is a safe and effective method in the treatment of high blood flow vascular malformations of oral maxillofacial region.

Objective To evaluate the clinical value of internal carotid artery occlusion in treatment of intractable epistaxis caused by carotid artery siphon traumatic lesions.Methods A total of 37 patients with intractable epistaxis caused by traumatic carotid artery siphon pseudoaneurysm or carotid cavernous fistula were retrospectively analyzed.All the patients underwent embolization from October 1998 to June 2010,including 34 men and 3 women with the age ranged from 25 to 65 years and a average of 40 years.Only lesions were occlued in 12 cases without involving the internal carotid artery,while occlusions of internal carotid artery were performed in the rest 25 cases.Results Thirty-six patients were cured without recurrent hemorrhage after embolization.Only 1 patient with carotid artery occlusion died 48 hours after operation.Conclusion For patients with carotid arterial intractable epistaxis,if the elimanation of the lesions is not applicable and the collateral circulation of Willis ring has a good compensation,the use of detachable balloon or coil occlusion of ipsilateral internal carotid artery is a quick and easy method to save patients' lives.
