Packing Densities

The long-term outcome of endovascular coiling of cerebral aneurysms is directly related to the packing density at the time of treatment. In general, the highest packing density achievable is only about 45% due to the quasirandom distribution of currently available coils within aneurysms. We investigated whether packing densities could be maximized via more ordered coil configurations. Three different coil configurations—circular loops, planar spirals, and spherical helices—were investigated. The packing densities achievable in maximally filling the volume of an exemplar human basilar aneurysm with each coil configuration were calculated numerically. Coil packing simulations were also carried out for aneurysms idealized as spheres over diameters ranging from 2 mm to 30 mm. The packing densities with the loop, spiral, and spherical helix configurations were 82%, 60%, and 73%, respectively, for the human aneurysm model; the numbers of coils required were 693, 34, and 13, respectively. Simulations within idealized aneurysms suggest that aneurysms cannot be packed to more than 91% with coils of constant circular cross section. The spherical helix configuration provides a constant packing density (coefficient of variation of 0.4%) over the range of aneurysm diameters studied as compared to the two other configurations (coefficients of variation of 9% and 8%). Coil configurations that allow for ordered filling of cerebral aneurysms can potentially provide packing densities that are twice those currently achieved. The spherical helix configuration seems to be the most technically feasible and stable configuration of the three coil types investigated.

The Stability

The long-term outcome of detachable coil embolization of cerebral aneurysms is still unknown. The purpose of this study was to evaluate the stability of the anatomic occlusion of aneurysms treated with the Cook detachable coil system and assess the rate of recanalization and recurrence. A study involving 250 patients with 271 ruptured aneurysms treated with the Cook detachable system between January 1997 and September 2003 who subsequently underwent six month, one year and two year follow-up angiography were enrolled in the study. Angiographic findings were reviewed to determine the percentage of aneurysm occlusion. Long-term follow-up angiograms (at two years) demonstrated complete occlusion in 75% of cases, and subtotal occlusion in 25% of cases. Overall morbidity was 7.3%, aneurysm recurrence 3.2%, and aneurysm re-treatment 3.2%. Recurrent subarachnoid hemorrhage occurred in only one patient. Angiographic follow-up demonstrated the stability and durability of treatment with the Cook detachable coil system.
