Intracranial aneurysms are abnormal bulging portions of the cerebral artery wall and are a common cause of spontaneous subarachnoid hemorrhage. Although the cause of the development is not well understood, with congenital aneurysms accounting for the majority of cases, there are a number of factors that can trigger a ruptured cerebral aneurysm. The chief of neurosurgery is here to tell you what factors are associated with ruptured cerebral aneurysms. Cerebral aneurysms can develop at any age, and are common between the ages of 40 and 66. Some people describe cerebral aneurysm as an untimely bomb in the skull, so what factors can influence to trigger its rupture? Anxiety, stress, excitement, sudden rise in blood pressure, straining to urinate or defecate, late pregnancy, childbirth, physical labor, sexual intercourse, etc. are all triggers for aneurysm rupture. Many patients have pioneering symptoms such as paroxysmal headache, ocular muscle paralysis, diplopia, dizziness, and neck pain before bleeding, indicating that the aneurysm wall has been pathologically altered before rupture, and in the presence of triggers, the rupture of the aneurysm wall that has already ruptured occurs. Patients with cerebral aneurysms may experience a sudden increase in pressure in the aneurysm cavity during downward motion and straining to defecate, leading to rupture. In many cases, a sudden increase in pressure within the aneurysm cavity can be caused by straining during stool (constipation and diarrhea), leading to rupture. When the stool is dry, a force is applied and something goes wrong. In fact, forceful stool is only one of the representatives, doing downward motion, force, heavy physical labor (looking for gas cans), late pregnancy, childbirth, these factors may lead to a short-term increase in blood pressure, while people who carry out particularly stressful work, such as manipulators, police officers, etc., and some workers who need to work at height, these all need to be noted.
