“…[3][4][5][6][7][8][9][10]21,41 The evidence for securing ruptured aneurysms with neurosurgical clipping or endovascular coiling to prevent rebleeding is sound, and there is evidence from the International Subarachnoid Hemorrhage Trial that endovascular coiling is the preferred method when both techniques are equally suited. 21,[31][32][33][34][42][43][44][45][46][47] Logically, therefore, it follows that securing the aneurysm with endovascular coiling or neurosurgical clipping in the for the ultra-early (coiling within 24 hours of SAH) and not ultra-early (coiling at Ͼ24 hours post-SAH) groups. The "outcome shift" toward better outcomes in the ultra-early group is statistically significant (Pϭ0.001) when tested with the Mantel-Haenszel test for linear association.…”

Background and Purpose-The purpose of this study was to analyze whether treating ruptured intracranial aneurysms within 24 hours of subarachnoid hemorrhage improves clinical outcome. Methods-An 11-year database of consecutive ruptured intracranial aneurysms treated with endovascular coiling or craniotomy and clipping was analyzed. Outcome was measured by the modified Rankin Scale at 6 months. Our policy is to treat all cases within 24 hours of subarachnoid hemorrhage. Treatment delays are due to nonclinical logistical factors. Results-Two hundred thirty cases were coiled or clipped within 24 hours of subarachnoid hemorrhage and 229 at Ͼ24 hours.No difference in age, gender, smoking, family history of subarachnoid hemorrhage, aneurysm size, or aneurysm location was found between the groups. Poor World Federation of Neurological Surgeons clinical grade patients were overrepresented in the ultra-early group. Increasing age and higher World Federation of Neurological Surgeons clinical grade were predictors of poor outcome. Eight point zero percent of cases treated within 24 hours of subarachnoid hemorrhage (ultra-early) were dependent or dead at 6 months compared with 14.4% of those treated at Ͼ24 hours (delayed), a 44.0% relative risk reduction and a 6.4% absolute risk reduction (

Computational algorithms modeling the insertion of endovascular devices, such as coil or stents, have gained an increasing interest in recent years. This scientific enthusiasm is due to the potential impact that these techniques have to support clinicians by understanding the intravascular hemodynamics and predicting treatment outcomes. In this work, a virtual coiling technique for treating image-based aneurysm models is proposed. A dynamic path planning was used to mimic the structure and distribution of coils inside aneurysm cavities, and to reach high packing densities, which is desirable by clinicians when treating with coils. Several tests were done to evaluate the performance on idealized and image-based aneurysm models. The proposed technique was validated using clinical information of real coiled aneurysms. The virtual coiling technique reproduces the macroscopic behavior of inserted coils and properly captures the densities, shapes and coil distributions inside aneurysm cavities. A practical application was performed by assessing the local hemodynamic after coiling using computational fluid dynamics (CFD). Wall shear stress and intra-aneurysmal velocities were reduced after coiling. Additionally, CFD simulations show that coils decrease the amount of contrast entering the aneurysm and increase its residence time.

“…This high rate of complications eventually led to this procedure being abandoned, but this experience demonstrated the feasibility of the endovascular route in the treatment of intracranial aneurysms. 7 The search for a more malleable material suitable to filling an aneurysmal sac eventually led to the utilization of platinum coils. 8 The initial coils were relatively stiff, and their intra-aneurysmal deployment was poorly controlled.…”
