What is suprasellar aneurysm?
Thrombosed pituitary region aneurysms are relatively common and usually pose no problem in diagnosis. Occasionally however a thrombosed aneurysm can have unusual signal characteristics and may be mistaken for a solid or cystic mass such as a craniopharyngioma.
What are the surgical management of aneurysm?
Surgical clipping or endovascular coiling or a flow diverter can be used to seal off an unruptured brain aneurysm and help prevent a future rupture. However, in some unruptured aneurysms, the known risks of the procedures may outweigh the potential benefit.
What is located in the sella turcica of sphenoid bone?
Structure. The sella turcica is located in the sphenoid bone behind the chiasmatic groove and the tuberculum sellae. It belongs to the middle cranial fossa. The sella turcica’s most inferior portion is known as the hypophyseal fossa (the “seat of the saddle”), and contains the pituitary gland (hypophysis).
Why are aneurysms clipped?
The goal of surgical clipping is to isolate an aneurysm from the normal circulation without blocking off any small perforating arteries nearby. Under general anesthesia, an opening is made in the skull, called a craniotomy. The brain is gently retracted to locate the aneurysm.
Can a clipped aneurysm rupture?
Clipping is a way to treat an aneurysm by placing a small metal clip across the neck of the aneurysm—the base of the bulge. The aneurysm is thereby sealed off from the blood flow; it cannot burst or spill blood into the brain.
What is the Turkish saddle?
Turkish saddle –> sella turcica. (Science: anatomy) A transverse depression crossing the midline on the superior surface of the body of the sphenoid bone and containing the pituitary gland. It is named turkish saddle from its resemblance to the saddle used by turks.
What does Turcica mean?
depression
Listen to pronunciation. (SEL-uh TER-sih-kuh) A depression of the bone at the base of the skull where the pituitary gland is located.
What are the side effects of clipping an aneurysm?
Complications specifically related to aneurysm clipping include vasospasm, stroke, seizure, bleeding, and an imperfectly placed clip, which may not completely block off the aneurysm or blocks a normal artery unintentionally.
What is the success rate of brain aneurysm surgery?
Posterior circulation aneurysm comprised 13.51%. One hundred forty-three (96.62%) aneurysms were successfully clipped, and 3.37% were either wrapped or later coiled. Surgical-related mortality was 0.82% (1 patient because of air embolism).
