Surgery is one of the common treatment methods for intracranial aneurysms. However, the occurrence of postoperative complications remains an important issue. The following will introduce the precautions and preventive measures after intracranial aneurysm surgery to help patients recover better.
1、 What are the common surgical complications of intracranial aneurysms?
Intracranial aneurysm is a serious disease, and the occurrence of postoperative complications is related to multiple factors. Among them, the patient's basic condition is an important factor, such as age, physical condition, medical history, etc., which can affect postoperative recovery. In addition, surgical techniques, surgical experience, and factors such as the size and location of aneurysms and necks can also affect the occurrence of postoperative complications.
Common complications after intracranial aneurysm surgery include cerebral edema, postoperative rebleeding, intracranial infection, cerebral vasospasm, and hydrocephalus. The incidence, severity, and prognosis of these complications are related to the specific condition of the patient and the surgical situation.
Cerebral edema is one of the common complications of intracranial surgery, usually occurring within 1-2 weeks after surgery. It can lead to increased intracranial pressure, compression of brain tissue, and impaired brain function. In order to alleviate brain edema, doctors will provide treatment measures such as medication and mechanical ventilation.
Postoperative rebleeding is another common complication, usually occurring within 24 hours after surgery. The reasons for rebleeding may be incomplete hemostasis during surgery, blood pressure fluctuations, or improper postoperative activities. Once bleeding occurs again, it is necessary to undergo surgery or take other treatment measures in a timely manner, such as interventional therapy or drug therapy.
Intracranial infection is a serious complication that can lead to increased intracranial pressure, brain tissue damage, and death. To prevent infection, doctors will use antibiotics and anti-inflammatory drugs before and after surgery. If an infection occurs, it is necessary to promptly use potent antibiotics and undergo surgical treatment.
Cerebral vasospasm and hydrocephalus are two other common complications. Cerebral vasospasm may lead to serious consequences such as cerebral ischemia and infarction, requiring medication or intervention therapy. Hydrocephalus may lead to symptoms such as increased intracranial pressure, headache, and nausea, requiring medication or surgical treatment.
2、 Postoperative precautions
(1) After intracranial aneurysm surgery, the patient's bed rest requirements are very important. Firstly, patients need to maintain a supine position for 24 hours, which helps reduce pressure on the surgical site and promote healing. At the same time, the surgical limb needs to be immobilized for 24 hours to prevent bleeding or wound rupture caused by intense exercise. For the site of femoral artery puncture, it is necessary to apply salt bag pressure for 6 hours to stop bleeding and prevent hematoma formation. During bed rest, patients should remain quiet and avoid excessive activity or vigorous exercise. Proper turning over can alleviate fatigue and lower back pain, but the hip joint of the operated limb should be kept straight and the healthy lower limb should be freely extended and bent.
（2） In terms of diet, patients need to wait until anesthesia clears and intestinal peristalsis recovers before eating. Liquid diets are the preferred choice because they are easy to digest and do not impose excessive burden on the intestines. Although milk is nutritious, it can easily cause bloating, so it is not recommended to drink. As the body recovers, patients can gradually transition to a normal diet after 2-3 days. To promote wound healing and physical recovery, patients should consume foods rich in protein, vitamins, and minerals. Meanwhile, drinking plenty of water can help eliminate contrast agents and prevent constipation.
（3） Postoperative headache is one of the common complications, especially after arterial aneurysm embolization. The cause of headaches may be related to subarachnoid hemorrhage, which directly stimulates the dura mater and leads to headaches. With the absorption of bleeding and the disappearance of cerebral edema, headache symptoms usually gradually alleviate or disappear. However, if the headache worsens or lasts for a long time, it is necessary to inform the doctor and receive targeted treatment. For patients with unruptured aneurysms or no preoperative headache symptoms, the likelihood of postoperative headache is relatively low.
In addition to headaches, it is also necessary to closely monitor the occurrence of other head symptoms. For example, newly emerging symptoms such as headaches, nausea and vomiting, consciousness disorders, and limb movement disorders may be signs of serious complications. For example, complications such as rebleeding, cerebral vasospasm, aneurysm rupture, subcutaneous hematoma at the puncture site, cerebral ischemia, and femoral artery thrombosis may occur in these symptoms. Therefore, once these symptoms appear, it is necessary to promptly inform the doctor and receive corresponding treatment measures.
（4） In terms of postoperative observation, patients need to pay attention to the following points: firstly, observe whether there are symptoms such as pain, bleeding, and hematoma at the puncture site; Secondly, pay attention to the sensation and movement of the limbs. If numbness, pain, or movement disorders occur, inform the doctor promptly; Thirdly, pay attention to the color and temperature of the lower limb skin, as well as the pulsation of the dorsalis pedis artery, in order to detect lower limb thrombosis early; Fourthly, pay attention to observing the state of consciousness, changes in pupils, and limb movements in order to promptly detect complications such as intracranial hemorrhage and cerebral ischemia; Fifth, monitor temperature changes and promptly detect signs of infection; Sixth, follow the doctor's advice to regularly undergo CT, MRI and other imaging examinations in order to detect complications early and handle them in a timely manner.
3、 How to prevent intracranial aneurysms?
Chronic diseases such as hypertension and hyperglycemia increase the risk of intracranial aneurysms, so maintaining normal blood pressure and blood sugar levels is crucial for preventing aneurysms. At the same time, one should avoid unhealthy lifestyle habits such as long-term excessive fatigue and mental stress, which may also affect the health of intracranial blood vessels.
A balanced diet, moderate exercise, and good sleep habits can help maintain physical health. Avoiding overeating and excessive intake of high-fat and high sugar foods, eating more fresh vegetables, fruits, and fiber rich foods can help control weight and blood lipid levels. At the same time, quitting smoking and limiting alcohol consumption is also an important measure to prevent intracranial aneurysms.
3. Regular head imaging examinations, such as CT angiography or magnetic resonance angiography, can be performed to understand changes in intracranial blood vessels and detect potential aneurysms or lesions early. Early detection and treatment of intracranial aneurysms can significantly reduce the risk of rupture and bleeding, and improve treatment outcomes.
4. People with a family history of intracranial aneurysms are considered high-risk individuals and should pay special attention to their own health status and undergo regular relevant examinations. In addition, maintaining a positive mindset and emotional stability is also beneficial for preventing intracranial aneurysms. Reducing stress, adjusting mindset, and cultivating good psychological qualities can help lower the risk of developing aneurysms.
