Background
We present a single-centre experience of procedural complications suffered by patients undergoing endovascular treatment for a ruptured saccular intracranial aneurysm at Tampere University Hospital, Finland, between 2000 and 2014.
Method
From 2000 to 2014, we treated 1,253 patients with aneurysmal subarachnoid haemorrhage, 491 of whom received endovascular treatment. Clinical data were collected retrospectively from the hospital’s aneurysm database. A procedural complication was defined as having occurred whenever there was a documented new event in the patient’s medical records or a note of a technical complication written by an interventionist after endovascular treatment. Procedural complications could be with or without clinical symptoms.
Results
Nearly 40% (491/1253) of the patients were treated with the endovascular method. Procedural complications occurred in 11.4% (56/491) of cases. The morbidity rate was 4.5% (22/491) and the mortality rate was 0.2% (1/491). Of the 56 complications, ischaemic complications occurred in 52% (29/56), haemorrhagic complications occurred in 27% (15/56) and technical complications occurred in 21% (12/56) of cases. In 61% (34/56) of the cases, the procedural complication did not cause any clinical symptoms.
Conclusions
The total risk for procedural complications leading to postoperative disability or death at our institute was 4.7%. The complication frequency is in accordance with previous reports. Endovascular treatment of ruptured intracranial aneurysms is a safe treatment method when patient selection is carefully performed.
