Morbidity/Mortality

Despite advances in microsurgery, anesthetic techniques, and critical care, the morbidity and mortality rates of SAH remains high at 25–35% and 40–50%, respectively. Age and neurologic status on hospital admission continue to be the best...

predictors of outcome.

In contrast, the operative mortality rate for elective clipping is close to 0, with morbidity ranging between 0% and 10%, especially if the surgeon is experienced in the procedure and utilizes the latest microsurgical techniques. In this situation, morbidity is most closely related to aneurysm size and location. Generally, elective clipping of an unruptured aneurysm is associated with better outcomes than ruptured aneurysms because the brain has not been damaged by the SAH prior to the procedure.

To repair a cerebral aneurysm by craniotomy, an incision is made in the skin on the side of the head (A). Small holes are drilled in the skull (B), and a special saw is used to cut the bone between the holes (C). The bone is removed (D), and the aneurysm is treated (E). The bone is replaced, and the skin is sutured closed (F). (Illustration by GGS Inc.) To repair a cerebral aneurysm by craniotomy, an incision is made in the skin on the side of the head (A).

Definition

Cerebral aneurysm repair involves corrective treatment of an abnormal blood-filled sac formed by localized expansion of an artery or vein within the brain. These sacs tend to form at the juncture between a primary vessel and a branch. If the vessel involved is an artery, the lesion is also known as a berry aneurysm because of its round, berry-like appearance.

Purpose

The purpose of the surgical treatment of cerebral aneurysms is to isolate the weakened vessel area from the blood supply. This is commonly done through the strategic placement of small, surgical clips to the neck of the lesion. Thus, the aneurysm becomes isolated from the normal circulation without damaging adjacent vessels or their branches and shrinks in size to become undetectable, a process known as aneurysm obliteration.
