What are common after effects for a brain aneurysm operation using the coil embolization procedure?

Depends: If ruptured or not. If not ruptured may have a headache up to one week or so. Very small risk of hydrocephalus or delayed stroke. May have discomfort at the puncture site at your groin for a few days.

Aneurysm coil: Coil embolization has inherent risks as does open surgery. Consult a place with access to both so as to get the best non biased approach to a particular condition. There are plus and minuses to both approaches.

Rare side effects: You can have problems in three different areas after an embolization procedure: 1. The groin site where you gained access. 2. The arteries all the way up to the head. 3. The brain in the form of a stroke or a bleed. That being said, the rate of complication from a coiling of an aneurysm is extremely low in experienced hands.
