Objective To describe the transvenous catheterization technique for the treatment of cavernous sinus dural arteriovenous fistulas (CSdAVFs), including its indications, complications and *** Eight patients with symptomatic CSdAVFs were treated by endovascular embolization with platinum coils, via the inferior petrosal sinus (IPS) in 6 patients, and via the Sylvian vein after surgical exposure in other 2 *** Complete angiographic resolution of the fistula was obtained in six patients immediately after the procedures, and a complete resolution of symptoms and signs was achieved in all patients. The residual fistulas in two patients disappeared completely in the follow-up *** Transvenous embolization is a useful and safe approach in the management of CSdAVFs.

Background Usually, cavernous dural arteriovenous fistula can be treated via transarterial approaches. However, in many complicated patients, transvenous approaches are superior to the transarterial ones because of the difficulties during a transarterial operation. In this study, we retrospectively analyzed the outcomes of 28 patients with cavernous dural arteriovenous fistula treated by transvenous embolization. Methods From September 2001 to December 2005, 28 patients with 31 cavernous dural arteriovenous fistulae were treated with transvenous embolization in Beijing Tiantan Hospital. The involved cavernous sinuses were catheterized via the femoral vein-inferior petrosal sinus approach or the femoral-facial-superior ophthalmic vein approach, and embolized with coils （GDC, EDC, Matrix, Orbit or free coil） or coils plus silk. The patients were followed up for 3 to 26 months. Results All the 31 cavernous sinuses in the 28 patients were successfully embolized. Complete angiographic obliteration of the fistulae was achieved immediately in 25 patients. Residual shunting was observed in the other 3, who had drainage through the pterygoid plexus （2 patients） or the inferior petrosal sinus （1） after the operation. Headache and vomiting were the most common symptoms after the embolization. In 3 patients, who achieved complete angiographic obliteration immediately, the left oculomotor nerve palsy remained unchanged after the operation. Transient abducens nerve palsy was encountered in 1. In 1 patient, the occular symptoms were improved after the operation, but recurred 4 days later, and then disappeared spontaneously after 5 days. During the follow-up, no patient had recurrence. Three months after the operation, angiography was performed on the 3 patients with residual shunting. Two of them had angiographic cure, the other had residual drainage through the pterygoid plexus. Conclusions Transvenous catheterization and embolization of the cavernous sinus is a safe and ef

Aim: To determine if androgens directly regulate veno-occlusion or if androgens act indirectly to maintain the penilestructures which control outflow. Methods: Using CASTRATE and TESTO rats, measurement was made of meanarterial pressure (MAP), intracavernosal pressure (CCP), and intracavernosal flow (CCF) during erection resultingfrom stimulation of the autonomic innervation of the penis. CCP and CCF were also measured during saline infusioninto the cavernosal sinuses before and after treatment with sodium nitroprusside (SNP, a nitric oxide donor drag) tofully relax cavernosal smooth muscle. Penile tissue was also collected to measure the content of α actin and proline andhydroxyproline to determine if brief withdrawal of androgenic support led to changes in the number of smooth musclecells or the collagen content of the tissue. Results: Infusion of saline into the cavernosal sinuses demonstrated thatveno-occlusion was defective in CASTRATE rats while reno-occlusion was fully functional in TESTO ***, veno-occlusion could be induced in CASTRATE rats if they were first treated with SNP. Thisobservation suggests that failure of veno-occlusion in the CASTRATE rats is due to a deficiency in the production of NOresulting in a reduction in the degree of relaxation of the penile smooth muscle. The measurements of smooth muscleα actin and proline and hydroxyproline content of collagen showed that both were unaffected by castration and that thebasic structure of the penis did not degenerate after one week without androgenic support. Conclusion: Theseresults can be interpreted to mean that androgens control the veno-occlusive mechanism indirectly via a NO dependentmechanism and not by maintaining the structures of the penis which are essential to reno-occlusion.

BACKGROUND： The attack of meningiomas has sex and age differences. Previous studies indicated that children and adult patients had different clinical and pathological features. Due to the limitation of conditions and technique of diagnosis and treatment, some clinical and pathological features of meningiomas in children should be further recognized. OBJECTIVE： To summarize the clinical and pathological features in 15 children with intracranial meningiomas DESIGN ： A retrospective case analysis SETTING： The hospitals which the first author had been working inPARTICIPANTS ： Fifteen children with intracranial meningiomas were selected from the hospitals the frst author had been working in from June 1996 to June 2006. There were 9 boys and 6 girls, aged 1.8-15 years, with an average of 9.8 years. The duration from attack to diagnosis was 1 month to 2.5 years, with an average of 13 months. Inclusive criteria：（1） Clinically diagnosed, operated and confirmed pathologically; （2）≤ 15 years; （3） The children and their relatives were all informed and agree with the detection. METHOOS ： The clinical manifestations, imaging data, preoperative diagnosis and misdiagnosis, site and size of tumor, operative treatment and pathological data were retrospectively summarized. Thirteen of 15 children with intracranial meningiomas were followed up by means of reexamination for 1-8 years, and the postoperative recurrence were observed. MAIN OUTCOME MEASURES： Clinical manifestations, imaging data, preoperative diagnosis and misdiagnosis, site and size of tumor, operative treatment, pathological data, recurrence conditions of 1 to 8 years follow-up.RESULTS ： Thirteen of the 15 children with intracranial meningiomas were involved in the analysis of results, and 2 lost to the follow-up. （1） The main clinical manifestations at diagnosis were headache in 11 cases （73%, 11/15）, vomiting in 8 cases （53%, 8/15）, papilledema in 9 cases （60%, 9/15）, hypopsia in 6 cases （40%, 6115）, epil

We report a rare case of internal carotid artery agenesis with stenosed intercavernous anastomosis. A 59-year- old male patient presented with a new infarction in the left basal ganglia. Magnetic resonance angiography and cerebral angiography showed that the right internal carotid artery disappeared from the origin to the foramen lacerum segment, and there was an anastomotic artery with severe stenosis passed through the floor of the sella and in front of the cavernous sinus. The right A1 segment of the anterior cerebral artery was absent and A2 segment was supplied by the normal contralateral internal carotid artery via the anterior communicating artery.
