cavernous hemangioma resection

Cavernous hemangioma is a vascular malformation of low blood flow that occurs at birth, also known as venous malformation. Vascular damage generally develops slowly, often in childhood or adolescence, and is not significantly increased in adulthood. Most venous malformations are spongy, hence the name. In addition to the skin and subcutaneous tissue, lesions can also occur under the mucosa, muscles and even bones. Cavernous hemangioma, when ruptured due to trauma or secondary infection, has the risk of causing severe blood loss. There are many reports in the literature about severe bleeding or even fatality in the removal of bones, especially cavernous hemangioma in the mandible. In the past, the inclusion of cavernous hemangioma in hemangioma, Mulliken according to the histological features of vascular endothelial cells, hemangioma is divided into two categories of hemangioma and vascular malformation, and vascular malformation is divided into low flow vascular malformation and high velocity blood vessels deformity. Cavernous hemangioma is a venous malformation in low-flow vascular malformations. Treatment of diseases: hepatic cavernous hemangioma congenital hemangioma Indication 1. Hemangioma occurs in areas that are prone to bleeding, infection (such as cavernous hemangioma of the lips) or obstructive function. 2. Hemangiomas grow rapidly, and due to conditions, can not be frozen or treated with sclerosing agents. Contraindications 1, patients with bleeding tendency should first treat coagulation function, and then surgery. 2, allergic to local anesthetics, or anti-anaesthetic should pay attention. Preoperative preparation 1. Carefully consider and fully estimate the extent of hemangioma and its relationship with important tissues and organs in the vicinity, and formulate appropriate treatment plans. 2. For larger cavernous hemangioma, sclerotherapy may be injected as appropriate to reduce the volume and then resection. 3. After resection of the hemangioma, it is estimated that the wound edge cannot be directly sutured, and skin grafting or orthotopic flap repair is required. The skin preparation for the donor site should be prepared before surgery. 4. Larger, deeper hemangioma should be prepared before surgery. Surgical procedure The incision should be slightly larger, or a fusiform incision to fully reveal the tissue surrounding the aneurysm. Passive and sharp separation from normal tissue surrounding the hemangioma. The branches that penetrate the fascia layer and the main blood vessels that enter the tumor are separated, ligated, and cut off one by one, and the tumor is carefully removed. Be careful not to damage the tumor to avoid bleeding and increase the difficulty of surgery. The incision was sutured layer by layer. Patients with skin defects should be skin grafted or flapped at the same time. The wound is pressure bandaged and the limb is properly fixed. complication 1. Incision infection: timely use of effective antibiotics, a small amount of hormones and hemostatic drugs, intravenous medication for 7 days, to prevent wound infection. 2. Local bleeding.
