In patients with sickle cell disease cerebral aneurysm formation is thought
to be a complication of recurrent red cell sickling, and multiple aneurysm
s have been reported in these patients. Management of patients with suspect
ed cerebral aneurysm has traditionally involved cerebral vessel angiography
followed by craniotomy and aneurysmal clipping. In patients without sickle
cell disease, non-operative intervention in the form of endovascular coil
embolization is increasingly being used to ablate aneurysms, but has not th
us far been reported in patients with sickle cell disease. We report two pa
tients with sickling disorders who have undergone coil embolization of cere
bral aneurysms with good functional and radiological outcomes. These patien
ts illustrate that endovascular coiling is useful in the treatment of cereb
ral aneurysms associated with sickling disorders, although, as with surgica
l intervention, preparation with exchange transfusion is appropriate.
