Whether subarachnoid hemorrhage requires surgery depends on the specific circumstances, as there are many causes of subarachnoid hemorrhage, commonly caused by aneurysms. Therefore, the decision to perform surgery is based on the size of the aneurysm and the amount of bleeding, as well as the patient’s overall condition to determine if they can tolerate surgery. Additionally, some subarachnoid hemorrhages may be caused by arteriovenous malformations or other reasons. The decision whether to opt for surgery or conservative treatment also depends on the amount of bleeding and the patient's symptoms, and the risk involved is relatively high.

Subarachnoid hemorrhage should go to which department?

Subarachnoid hemorrhage is also relatively common in clinical settings. Its symptoms primarily include severe headaches, reflex vomiting, possible consciousness disturbances, and even seizures. Following the occurrence of subarachnoid hemorrhage, a cranial CT scan can be used for a definitive diagnosis. Patients typically seek treatment in neurology or neurosurgery departments. After admission to a neurology ward, DSA (Digital Subtraction Angiography) can be conducted to accurately locate the bleeding site, and interventional embolization treatments may be considered. If the patient has a large volume of subarachnoid hemorrhage, neurosurgery might be considered for the removal of intracranial hematomas or decompressive craniectomy, among other procedures.

Subarachnoid Hemorrhage CT Imaging Manifestations

Subarachnoid hemorrhage is caused by the rupture of cerebral blood vessels due to various reasons, allowing blood to flow into the subarachnoid space. Common causes include trauma and rupture of congenital aneurysms. Subarachnoid hemorrhage caused by the rupture of congenital aneurysms typically presents on a CT scan with high-density appearances at the base of the skull in the brain pools, especially widespread columnar high-density appearances in the suprasellar cistern, lateral fissure cistern, anterior interhemispheric fissure, and around the circumferential pool. If the subarachnoid hemorrhage is due to trauma, the abnormalities are more localized, generally appearing in the brain pool or cerebral sulcus on the side of injury with high-density appearances, and may also be accompanied by hematomas within the ventricles or bleeding in other locations.

Is subarachnoid hemorrhage considered a minor injury?

Subarachnoid hemorrhage depends on the amount of bleeding and the location to determine the severity of the condition. It can be life-threatening in severe cases. If symptoms such as headache and severe vomiting occur, the possibility of subarachnoid hemorrhage should be considered. Initially, a cranial CT scan should be conducted to confirm the diagnosis. Further investigations should include cranial MRI or CTA vascular imaging, preferably CTA, to determine whether there is rupture bleeding caused by an aneurysm. In such cases, it is necessary to consider whether emergency surgery is required, based on the amount of bleeding and the condition of the blood vessels, and the possibility of an aneurysm to guide further treatment.

Nursing Measures for Subarachnoid Hemorrhage

Subarachnoid hemorrhage is a rather dangerous disease that develops very quickly, causing severe headaches, nausea, vomiting in patients, and this disease has a high probability of bleeding, potentially causing some cerebral vasospasm, leading to secondary thrombus formation. Besides prompt treatment and identifying the cause, such as clipping an aneurysm, nursing measures are also very important. Common nursing measures mainly include: First, it is essential to educate the patient to stay in bed and rest absolutely, as premature activity may cause the aneurysm to rupture and rebleed. Second, the patient must be instructed to maintain smooth bowel movements and a stable emotional state to prevent increased intracranial pressure and rebleeding due to emotional excitement or constipation. Third, the patient should be encouraged to drink more water and be given sufficient fluids to prevent cerebral vasospasm and low perfusion effects. Other nursing measures include stabilizing the patient's mood and providing sedation when necessary.
