**夏季动脉瘤破裂风险提升，专家呼吁警惕**
随着炎炎夏日的到来，不仅热浪滚滚，民众的健康隐患也随之增多。据中国新闻网报道，上海冬雷脑科医院脑血管病中心学术主任盖延廷主任医师指出，夏季应特别警惕动脉瘤破裂出血的风险。夏季炎热的天气不仅导致人体大量出汗，从而引发脱水，还可能使血管扩张，血压产生波动，这都为高血压患者增加了额外的压力，使血流对动脉壁的冲击增强。同时，高温下，情绪波动也易加剧，交感神经的兴奋性增加，再加上早晚温差大，导致血管在短时间内急剧收缩和舒张，这些因素都会增加脑动脉瘤破裂的潜在风险。
盖延廷主任提醒，不同年龄段的人群应采取不同的预防措施。建议35岁以上的成年人每3年到5年进行一次脑健康筛查，包括脑部核磁共振、脑部血管检查以及颈部血管检查等，以期及早发现潜在的动脉瘤风险。对于已知动脉瘤的患者，尤其需要注意以下几点：保持血压稳定，避免情绪的剧烈波动；减少户外活动的时间和强度，避免剧烈运动和突然发力；保持大便通畅，避免用力排便；戒烟限酒，坚持清淡饮食和健康的生活方式。
此外，动脉瘤破裂前可能出现一些预兆症状，如先兆性头痛、睁眼困难等，一旦出现这些症状，应立即就医检查，以避免延误治疗。
专家分享的一个病例表明，即使症状看似轻微，如李先生的肢体突然无力，也可能是动脉瘤破裂的前兆。李先生在症状加重后，被确诊为右侧大脑中M2段动脉瘤，最终在上海成功接受了颅内动脉瘤支架辅助栓塞术，术后恢复迅速。
盖延廷主任强调，夏季是动脉瘤破裂的高发期，公众应提高警惕，加强自我监测，及时就医，以降低潜在的健康风险。

**Summer Caution: Elevated Risk of Subarachnoid Hemorrhage from Aneurysms**
As summer’s heat rolls in, not only does it bring scorching temperatures, but it also poses additional health hazards to the populace. According to China News Service, Dr. Gai Yanting, the academic director of the Brain Vascular Disease Center at Shanghai Donglei Brain Science Hospital, emphasizes the heightened risk of aneurysm rupture and bleeding during the summer months. The scorching weather leads to excessive sweating, causing dehydration, and can also result in vasodilation, leading to fluctuations in blood pressure. This adds extra stress to patients with hypertension, increasing the impact of blood flow on the arterial walls. Moreover, under the influence of high temperatures, emotional fluctuations are more likely to occur, with the sympathetic nervous system becoming more active. The large temperature differences between day and night also cause the blood vessels to rapidly constrict and dilate within a short period, all of which contribute to the increased potential risk of rupturing cerebral aneurysms.
Dr. Gai Yanting advises that individuals of different age groups should take different preventive measures. He recommends that adults over 35 undergo brain health screenings every 3 to 5 years, including brain MRI, brain vascular examinations, and neck artery examinations, to detect potential aneurysm risks early. For patients who have already been diagnosed with aneurysms, they should pay particular attention to maintaining stable blood pressure, avoiding extreme emotional fluctuations; reducing the time and intensity of outdoor activities, avoiding intense exercise and sudden exertion; maintaining smooth bowel movements, avoiding strenuous efforts to defecate; quitting smoking and limiting alcohol intake, adhering to a healthy diet and lifestyle.
Moreover, there are premonitory symptoms of aneurysm rupture, such as premonitory headaches and difficulty in opening the eyes. Should these symptoms appear, immediate medical attention should be sought to avoid delaying treatment.
A case shared by the expert illustrates that even seemingly minor symptoms, such as Mr. Li’s sudden weakness in the limbs, can be a precursor to aneurysm rupture. Mr. Li was diagnosed with a right middle cerebral M2 segment aneurysm after his symptoms worsened and was successfully treated with a cerebral aneurysm embolization assisted by a stent in Shanghai.
Dr. Gai Yanting stresses that summer is a high-risk period for aneurysm rupture, and the public should be vigilant, enhance self-monitoring, and seek medical attention promptly to reduce potential health risks.
