Abstract：

Objective To investigate the application of assisted coiling techniques in the treatment of complex intracranial aneurysms.Methods From Jun.2007 to Aug.2010, 36 patients with 41 complex intracranial aneurysms were treated by varient endovascular methods, including balloon, stent-assisted coiling and double microcatheter coiling techniques.Results Among the 33 wide-neck aneurysms, 11cases underwent balloon-assisted coiling, in which 7 were totally occluded, 3 subtotally occluded, 1 diverted to double microcatheter treatment after failure balloon placement 15 cases underwent stent-assisted coiling, in which 10 were totally occluded, 2 subtotally or partially occluded respectively, 1 by single stent placement without coiling.8 cases accepted double microcatheter treatment, 6 were totally occluded, 1 subtotally occluded and 1 partially occluded.All 8 fusiform aneurysms were treated by stent-assisted coiling, one case was totally occluded, 6 subtotally occluded, and another one was treated by single stent placement.The complications were found in 3 patients, including intra-operative thrombosis in 2 cases and dysopia in one case.Conclusion Balloon, stent-assisted coiling and double microcatheter techniques are safe and effective in treating complex intracranial aneurysms, but it should be determined by the position and morphologic characteristics of aneurysms as well as the patients' clinical condition.

Abstract：

Objective To describe a geometric parameter for delineating the extent to which the parent artery is incorporated by the aneurysm neck, and to investigate the application of this parameter in endovascular treatment of intracranial aneurysm.Method In the 2D cross-section image obtained from the digital subtract angiography which containing simultaneously the aneurysm neck and the parent artery, the vessel lumen boundary of the parent artery is idealized to be a circle and two boundary points were thus determined in this circle where the aneurysm neck incorporating with the parent artery.The central angle formed by these two points and the circle center was defined as the arcuate neck angle, a new geometric parameter.Eight intracranial aneurysms embolized by utilizing the balloon-in-stent technique were reviewed for their measurement results of the arcuate neck angle, as well as their imaging and endovascular therapeutic data.The feasibility and practicability of utilizing this geometric parameter in endovascular treatment was investigated.Results The arcuate neck angle was more than 90° in all eight aneurysms.The measurement detail was as the following: more than 90° and less than or egual to 135° in four intracranial aneurysms,more than 135° and less than or egual to 180° in two,more than 180° and less than or egual to 225° in one, more than 225° and less than or egual to 270° in one aneurysm.These aneurysms were all successfully coil embolized.The margin of coil mass at the aneurysm neck appeared to be an arc, where the vessel wall of parent artery was reconstructed, and the aneurysm neck was also satisfactorily occluded for all cases.Conclusions The arcuate neck angle of intracranial aneurysms may approximately represent the extent to which the parent artery is incorporated by the aneurysm neck, especially for some fusiform ones or those without neck.It may benefit the optimization of endovascular therapy for intracranial aneurysms.

Pediatric intracranial aneurysms——clinical characteristics and therapeutic strategies

Objective To assess the radiological characteristics and therapeutic strategies of intracranial aneurysms in children. Methods From our dedicated neurovascular databank of patients, we reviewed 23 consecutive children who had 24 intracranial aneurysms. There were 14 boys and 9 girls with a mean age of 9.09 years ( range 1 - 14 years ). Results Intracranial aneurysms in children ≤ 14 years constituted 1.3% of all intracranial aneurysms. Internal Carotid artery (ICA) and middle cerebral artery (MCA) were the most frequent sites for aneurysms. About 58.3% of the aneurysms were complex, including dissecting, pseudoaneurysm, giant and fusiform aneurysm. 1/3 of all aneurysms were located in posterior circulation. Only 1 case had multiple aneurysms in this case series. Almost half of all cases presented with subarachnoid hemorrhage and others presented with mass effect. 14 cases underwent endovascular treatment. 4 patients received microsurgical therapy. 5 cases did not receive microsurgical or endovascular therapy, 2 of them whose aneurysms spontaneously thrombosed during follow up. One boy with left vertebral artery giant aneurysm died after endovascular therapy owing to gradual thrombosis in basilar artery. Another child had poor outcome because of rerupture of aneurysm before operation. Whereas the majority had a favorable outcome. Conclusions Intracranial aneurysms in children had many clinical and radiological characteristics different from those in adults : ( 1 ) remarkable male predominance; ( 2 ) ICA and MCA were the most common sites for aneurysms; (3) high incidence of large, traumatic, infectious, dissecting and fusiform aneurysms. (4)For pediatric intracranial aneurysms, both microsurgical approaches and endovascular treatment were effective. Endovaacular therapy was the best choice for complex aneurysms.

Outcomes of early physiotherapy in patients with cerebral aneurysms treated by surgical clipping or endovascular embolization

Early physiotherapy was given to 124 patients with ruptured or unruptured cerebral aneurysms who were treated by surgical clipping or endovascular embolization.Patients were divided into four groups according to their Hunt and Hess grade at admission and aneurysm treatment modality: Group 1,Hunt and Hess grade≤II and surgical clipping;Group 2,Hunt and Hess grade≤II and endovascular embolization;Group 3,Hunt and Hess grade≥III and surgical clipping;Group 4,Hunt and Hess grade≥III and endovascular embolization.Level of consciousness was evaluated using the Glasgow Coma Scale,functional status using the Glasgow Outcome Scale,level of the mobility using the Mobility Scale for acute stroke patients,and independence in activities of daily living using the Barthel Index.After early physiotherapy,the level of consciousness and functional status improved significantly in Groups 1,3,and 4;mobility improved significantly in all groups;and independence in activities of daily living improved significantly in Groups 1 and 3.At discharge, Groups 1 and 2 had better functional status than Groups 3 and 4.Level of consciousness,functional status,mobility and independence in activities of daily living improved after early physiotherapy. These findings suggest that early physiotherapy improved the prognosis of patients with cerebral aneurysms who were treated by surgical clipping or endovascular embolization.Patients with a worse clinical status at presentation had a poorer functional status at discharge.The outcome of physiotherapy was not affected by whether surgical clipping or endovascular embolization was chosen for treatment of the aneurysm.
