Surgical clipping
Aneurysms can be treated by clipping the base of the aneurysm with a specially-designed clip. Whilst this is typically carried out by craniotomy, a new endoscopic endonasal approach is being trialled. Surgical clipping was introduced by Walter Dandy of the Johns Hopkins Hospital in 1937. After clipping, a catheter angiogram or CTA can be performed to confirm complete clipping. Endovascular coiling
Endovascular coiling refers to the insertion of platinum coils into the aneurysm. A catheter is inserted into a blood vessel, typically the femoral artery, and passed through blood vessels into the cerebral circulation and the aneurysm. Coils are pushed into the aneurysm, or released into the blood stream ahead of the aneurysm. Upon depositing within the aneurysm, the coils expand and initiate a thrombotic reaction within the aneurysm. If successful, this prevents further bleeding from the aneurysm. In the case of broad-based aneurysms, a stent may be passed first into the parent artery to serve as a scaffold for the coils. Cerebral bypass surgery
Cerebral bypass surgery was developed in the 1960s in Switzerland by Gazi Yasargil. When a patient has an aneurysm involving a blood vessel or a tumor at the base of the skull wrapping around a blood vessel, surgeons eliminate the problem vessel by replacing it with an artery from another part of the body. Prognosis
Outcomes depend on the size of the aneurysm. Small aneurysms (less than 7 mm) have a low risk of rupture and increase in size slowly.
Familial nasal acilia is a rare congenital defect which is characterized by the complete absence of cilia on the epithelial cells of the respiratory tract. Symptoms are common within ones family and start as soon as one is born, with signs such as respiratory distress, dyspnea, lobar atelectasis, bronchiectasis and neo-natal pneumonia. Other symptoms that occur later in life include chronic moist coughing, chronic sinusitis, chronic otitis media, chronic rhinitis, and recurrence of upper and lower respiratory tract infections.Exact prevalence is unknown, OrphaNet estimates this condition to affect less than 1 out of every million people worldwide. R Soferman et al. described this disorder to be "autosomal recessive". == References ==
