Aneurysm interventional surgery

Interventional surgery for aortic aneurysm is a method of treating aortic aneurysm. The advantage of this method is that it causes less trauma to the patient, is easy to operate during treatment, and treats the exact site, thereby improving the treatment effect. This treatment method has been well received and unanimously recognized by many patients. Although this treatment has many benefits, it also has certain risks, and patients should be aware of the complications of surgery before deciding to undergo this procedure.

Interventional surgery for aortic aneurysms is applicable to: 1. Giant aneurysms that are difficult to remove or difficult to access (such as aneurysms in the cavernous sinus segment, the origin of the ophthalmic artery, and the vertebral-basilar artery system). 2. Patients who are elderly or have other systemic diseases and cannot tolerate surgery. 3. Those whose surgical clipping failed. 4. Fusiform wide-necked or no-necked aneurysms, saccular aneurysms. 5. All aneurysms except those with contraindications can be treated with embolization first. If embolization is unsuccessful, surgical treatment can still be considered.

Complications of interventional surgery for aortic aneurysm 1. The incidence of postoperative fever is generally around 30%, all of which are low-grade fevers that last for 1 to 2 days. If arterial embolization is performed, the body temperature can reach as high as 38.5-39.5℃ and be maintained for 6-10 days. After returning to normal, antibiotics are used to prevent infection. 2. Postoperative pain is mainly local distension and pain, with an incidence rate of 19%. No treatment is required. Patients with embolism have severe pain, and some are accompanied by lower limb discomfort. Patients with hepatic artery embolism need to use pethidine for pain relief, and the pain disappears in about a week. 3. Ionic contrast agents cause allergic reactions. False positives and false negatives may occur in iodine allergy tests and should be closely observed. Anti-allergic drugs should be used immediately after symptoms appear. If non-ionic contrast agents such as Uvitra are used, side effects are less likely to occur.

4. If the abdominal wall thrombosis is a small thrombus, it is often asymptomatic and can be absorbed on its own. Large blood clots can cause thrombotic symptoms. For patients who have been catheterized for a long time after surgery, lower limb pain, cold limbs, pale skin, and weakened pulsation of the popliteal artery and dorsalis pedis artery may occur. The site of embolism should be identified immediately. If it has not exceeded 7 days, conservative treatment such as urokinase can be used. If it exceeds 7 days and conservative treatment is ineffective, thrombectomy should be performed immediately. 5. Neurological complications: Embolism covers a large area and involves many branch blood vessels, which can lead to blood supply and nutritional disorders of the nerves in the corresponding area. In addition, anticancer drugs also produce neurotoxic reactions. Therefore, chemotherapy drugs should be selected with caution to avoid those with high neurotoxicity. 6. Damage to liver and kidney function may result in elevated transaminase levels and jaundice in some cases, which can be restored to normal with liver protection treatment. 7. Skin damage: Very few patients experience redness of the skin at the catheterization site and the ipsilateral buttocks. A few are accompanied by edema and papular rash, or even ulcers. These can be treated symptomatically and healed on their own.
