Abstract
Aneurysms with wide necks can be difficult to manage due to inability to contain the coil mass within the lesion. When standard devices will not suffice the use of two catheters delivering coils simultaneously into the aneurysm can often provide excellent results in terms of aneurysm obliteration. We report two cases of wide-necked aneurysms coiled successfully using the dual catheter technique. Both aneurysms were successfully treated using the dual catheter technique with coil retention within the aneurysm fundus and excellent flow throngh the afferent and efferent vessels. The dual catheter technique is an under-reported method for treating wide-necked aneurysms. Successful performance, however, relies upon considerations of coil type and delivery, coil deployment, catheter removal, and anticoagulation therapy.
