Utility of balloon-assisted Guglielmi detachable coiling in the treatment of cerebral aneurysms - A single center retrospective study

Balloon-assisted Guglielmi detachable coiling (BAGDC) is a new technical option developed to allow endovascular treatment of wide-necked aneurysms. Aim of the following work is to report a single center experience of BADGC of aneurysms with assessment of its efficacy and safety. BAGDC of wide-necked aneurysms (SNR close to 1) was retrospectively evaluated in 37 patients (28 females, nine males, mean age: 56.6 yrs, range: 27-81 yrs) who underwent the procedure between january 1999 and january 2002 for a total of 45 procedures on 41 aneurysms. Twenty-nine patients presented with SAH from an acutely ruptured aneurysm. In two patients BAGDC failed whereas 35 patients successfully underwent BADGC (39 aneurysms). Twenty-nine patients (31 aneurysms) were available for angiographic follow-up (mean: 10 mo, range: 3-24 mo). At the last angiographic follow-up 29133 aneurysms (87%) resulted stable and occluded (22 aneurysms with dense and seven with loose packing of the sac and the neck), two aneurysms showed regrowth, one aneurysm showed a neck remnant and another one a sac and neck remnant. Complications directly related to the procedure occurred in five patients (three perforations, one thromboembolism, one femoral AV) with a mortality and morbility rate of 2.7 and 5.4 respectively. BAGDC is a promising adjunct to treatment of wide-necked aneurysms broadening the spectrum of indications for endovascular treament of challenging aneurysms.
