A trapping-evacuation technique for giant carotid-ophthalmic segment aneurysm clipping in a hybrid operating theater.

It is essential to collapse giant carotid-ophthalmic (OA) segment aneurysms for successful microsurgical clipping. We present a trapping-evacuation technique utilising hybrid operating theater capabilities to soften OA aneurysms. The patients were prepared for both microsurgical and endovascular procedures.

[Feasibility and efficiency of embolization of spinal dural arteriovenous fistula].

Objective: To evaluate the feasibility and efficiency of embolization of spinal dural arteriovenous fistula (SDAVF).

Methods: From December 2010 to May 2012, there were 104 cases of SDAVF were treated, and 26 cases were selected to be treated with embolization. The inclusion criteria was as follows: (1) No anterior or posterior spinal artery originated from the fistula segment; (2) The segmental artery can be catheterized with guiding or micro catheter; (3) High flow in fistula; (4) Patient's situation was not suitable for surgery or general anesthesia.

[Treatment of cutaneous vertebral medullary angiomatosis].

Objective: Cutaneous vertebral medullary angiomatosis, also known as Cobb's syndrome, is a part of spinal arteriovenous metameric syndromes (SAMs), is derived from the vascular malformation triad of skin, bone, and spinal cord involvement. It is poorly managed with current treatment modalities. We reviewed the treatment of Cobb's syndrome series and summarized the experiences.

[Correlative study of carotid transient ischemic attacks and intracranial or extracranial angiostenosis].

Objective: To investigate the relationship between the clinical features of carotid transient ischemic attacks (TIA) and the intracranial or extracranial angiostenosis.

Methods: Location and degree of stenosis of involved arteries were examined by the digital subtraction angiography in 52 patients with carotid TIA.

Results: Intracranial or extracranial vascular lesions of different degrees were revealed in 45 patients (86.

[Different methods of intracranial-extracranial bypass surgery for the treatment of intracranial aneurysms].

Objective: To investigate the effects and methods of intracranial-extracranial (IC-EC) bypass surgery in the treatment of intracranial aneurysms.

Methods: The clinical material of 9 cases, who performed IC-EC bypass surgery before occlusion of the parental arteries of intracranial aneurysms, was studied retrospectively, especially how to evaluate the co-lateral circulation of the parental arteries and how to select the different methods of IC-EC bypass surgery.

Results: The co-lateral circulation in 9 cases was not enough to meet the need of the cerebral blood flow after occlusion of the parental arteries of the aneurysms.

[Diagnosis and treatment of spinal dural arteriovenous fistulas: 110 cases report].

Objective: To discuss the diagnosis, treatment and prognosis of spinal dural arteriovenous fistulas (SDAVF).

Methods: The clinical and following-up date from 110 patients with SDAVF diagnosed by spinal MRI and spinal angiography were analyzed retrospectively.

Results: Draining vein between fistula and spinal cord was interrupted by laminectomy approach as first choice in 61 patients, by hemi-laminectomy approach in 37, and by endovascular embolization in 12, and re-operation due to recurrence after embolization in 3.
