[Evaluation of carotid angiography and stenting for patients with contralateral carotid occlusion].

Objective: To discuss the efficiency and safety of carotid angioplasty stenting (CAS) in patients with contralateral carotid artery occlusion.

Methods: From January 2001 to January 2010, 56 carotid artery stenosis patients with contralateral carotid artery occlusion were performed CAS and the feature and results of these cases were analyzed retrospectively. All the cases were confirmed to be carotid artery stenosis with contralateral carotid artery occlusion by digital subtraction angiography (DSA).

[Embolization combined with endovascular stenting for treatment of intracranial pseudoaneurysms].

Objective: To evaluate the therapeutic effect of embolization combined with endovascular stenting in the for treatment of intracranial pseudoaneurysms.

Methods: Seventeen patients with intracranial pseudoaneurysms received endovascular treatment with coil placement, NBCA glue embolization and endovascular stenting, and the therapeutic effect was evaluated according to the findings in immediate postoperative and follow-up angiography.

Results: Fatal aneurysm rupture occurred in 1 case during embolization, and the surgical procedures were carried out smoothly in the remaining 16 cases.

[Clinical study on endovascular treatment for symptomatic atherosclerotic stenosis of basilar artery].

Objective: To study the feasibility, safety and validity of percutaneous angioplasty and stenting (PTAS) for symptomatic atherosclerotic stenosis of basilar artery.

Methods: The results of treatment and follow-up of 40 cases with symptomatic atherosclerotic stenosis of basilar artery performed PTAS from August 2003 to December 2009 were studied retrospectively, who had either recurrent transient ischemic attacks (TIAs) or obvious ischemic symptoms and resistant to medical therapy.

Results: PTAS were successfully performed in all the 40 cases and the post-operative average residual stenosis descended to 14% ± 11% from pre-operative 82% ± 14%.

[Cause and treatment for intracranial hemorrhage during the perioperative period of carotid artery stenting].

Objectives: To discuss the possible cause of intracranial hemorrhage and treatment after carotid artery stenting (CAS) in patients with carotid artery stenosis.

Methods: From January 2003 to August 2009, 403 patients with carotid artery stenosis that were performed CAS, intracranial hemorrhage occurred in 5 cases after the procedure. We analyzed the feature of these cases and perioperative management retrospectively to summarize the possible cause of intracranial hemorrhage and preventive measure.

[Carotid angioplasty and stenting for stenosis of extracranial carotid artery].

Objective: To evaluate the operation method and prevention from complications of extracranial carotid stenosis.

Methods: Three cases of carotid angioplasty and stenting for 271 patients with extracranial carotid stenosis were performed from October 2001 to June 2008. Before the operation, take Clopidogrel for 75 mg/d, Aspirin Delayed-Release Capsules for 100 200 mg/d, Simvastatin for 40 mg 1/night, for 5 - 10 d.

[Endovascular interventional treatment for symptomatic stenosis of middle cerebral artery].

Objective: To study the feasibility, security and validity of percutaneous angioplasty (PTA) or percutaneous angioplasty and stenting (PTAS) for symptomatic stenosis of middle cerebral artery.

Methods: The results of treatment and follow-up of 39 cases with symptomatic stenosis of middle cerebral artery who had either recurrent transient ischemic attacks (TIAs) or resistant to medical therapy and were performed PTA or PTAS were studied retrospectively.

Results: Among the 39 cases with stenosis of middle cerebral artery (23 in left, 13 in right, 3 in bilateral side and 5 cases combining with stenosis of carotid artery) PTA were successfully performed in 9 cases and PTAS in 30 (whose post-operative residual stenosis were less than 10%).
