Ruptured Brain Aneurysm Treated Successfully with Minimally Invasive Procedure in Taiwan

A 50-year-old woman in Nantou, Taiwan, has successfully undergone a groundbreaking minimally invasive procedure to treat a ruptured brain aneurysm that caused a sudden, severe headache.

The patient, identified by her surname Lin, experienced an intense headache accompanied by nausea and vomiting late one night. She was rushed to Nantou Hospital, where a CT scan revealed subarachnoid hemorrhage. Further examinations confirmed a rupture of an anterior communicating artery aneurysm.

Intracranial aneurysms are local abnormal bulges in the walls of cerebral arteries. Because the vessel walls are fragile, rupture can cause subarachnoid hemorrhage, a neurological emergency that can lead to severe brain damage or even death. Therefore, it is crucial to seize the golden treatment window and address it as soon as possible to prevent re-bleeding.

Nantou Hospital's neurosurgery team immediately performed the hospital's first endovascular embolization procedure. This minimally invasive technique involves inserting a catheter through the groin to fill the aneurysm with platinum coils, securing it in place. The procedure successfully sealed the ruptured artery, preventing further bleeding.

Smoking, alcoholism, high blood pressure, and the use of sympathomimetic stimulants are all important risk factors for intracranial aneurysms. Those over 50 years old, or with a history of intracranial aneurysms or a family history, also have a higher risk of rupture.

Dr. Chen Yi-An, a neurosurgery physician at Nantou Hospital, explained that intracranial aneurysms are abnormal bulges in brain arteries that can rupture, causing subarachnoid hemorrhage, a critical neurological emergency. He emphasized the importance of prompt treatment to avoid severe brain damage or death.

Dr. Chen noted that risk factors for aneurysms include smoking, heavy drinking, high blood pressure, and stimulant use. Individuals over 50, or those with a history of aneurysms, are at higher risk. He advised regular health check-ups, controlling chronic conditions, and seeking immediate medical attention for sudden, severe headaches, especially those described as "thunderclap headaches," accompanied by symptoms like nausea, vomiting, or altered consciousness.

Since most unruptured aneurysms have no obvious symptoms, the public should control blood pressure, quit smoking, avoid excessive alcohol consumption, and properly manage chronic diseases to reduce the risk of occurrence. If a sudden, unprecedented severe headache occurs, especially a so-called 'thunderclap headache,' accompanied by symptoms such as nausea, vomiting, altered consciousness, or limb weakness, seek medical attention immediately to avoid delaying treatment.
