Abstract: A middle-aged male presented to our department with a 4-day history of right lower extremity calf swelling with pain. After admission, hematoma was considered, but benign lesions were not excluded. The right lower limb hemangioma was resected under intravertebral anesthesia. Postoperative pathological findings were consistent with hemangioma rupture and bleeding changes, and the symptoms returned to normal after surgery. Basic information】Male, 51 years old 【Disease type】Hemangioma 【Visiting hospital】Liaoning Provincial People’s Hospital 【Visiting time】July 2020 【Treatment plan】Surgical treatment (right lower leg hemangioma resection + hematoma removal) + intravenous medication (cefoxitin sodium for injection + ketorolac aminotriol injection) + oral medication (Mai Zhi Ling tablets) 【Treatment cycle】Inpatient treatment for 15 days, outpatient treatment for 3 months Effectiveness of treatment] The swelling disappeared, and the painful symptoms of swelling were relieved significantly. The ultrasound suggested that the right calf was intermuscular fluid and the right popliteal vein was stagnant. The patient had a normal diet, normal sleep, normal bowel movements and no significant weight loss. The patient had a history of cerebral infarction for 2 years, with no obvious sequelae. On examination: localized subcutaneous bruising in the right lower limb, elevated skin temperature, posterior calf swelling, localized ulceration with crusting, indentation of the anterior tibial finger (-), indentation of the gastrocnemius muscle (+), weak dorsalis pedis artery pulsation, low skin temperature of the ankle and foot, and fair sensory function of the right lower limb, slightly limited motor function, the preliminary diagnosis was that the cause of lower limb swelling was to be investigated. After the patient was admitted to the hospital, further relevant examinations were performed, and the right lower extremity artery ultrasound showed no obvious abnormality, while the right lower extremity vein ultrasound showed deep venous flow stagnation. The hematoma was considered, but the benign lesion was not excluded. The patient’s symptoms and imaging data were considered to be a ruptured hemorrhagic subcutaneous hemangioma with local hematoma formation. Because of the patient’s obvious symptoms and the impact on sensorimotor function, surgery was indicated. After the patient’s consent, resection of the right calf hemangioma and removal of the hematoma were performed under intravertebral anesthesia. After the operation, the patient’s symptoms were obviously relieved and the incision healed well. The patient’s postoperative effect was remarkable. The patient’s swelling was significantly relieved, the pain score decreased day by day, the patient’s drainage flow decreased day by day, the incision healed well, no redness and exudation, the patient’s motor function fully recovered 1 week after surgery, no obvious painful walking symptoms, the patient’s incision completely healed 15 days after surgery, and the patient was discharged from the hospital. After discharge, the patient was followed up in the outpatient clinic 3 months after the operation. A scar was seen at the incision, but there was no other abnormality, no subcutaneous bruising, no pain and swelling, etc. The patient was reexamined by ultrasound in the outpatient clinic, which indicated that there was no obvious recurrence of hemangioma after the operation. Precautions We are glad that after the surgical treatment, the patient recovered and was discharged from the hospital after 15 days. However, after discharge, we must follow the doctor’s prescription for regular re-examination, and at the same time, carry out appropriate exercise to prevent the occurrence of deep vein thrombosis, in addition, diet and rest are also important factors for post-operative recovery. 1, after limb hemangioma resection, we should pay attention to a light diet, drink more water, eat less greasy and allergy-prone food, avoid spicy and stimulating food, and observe the healing of the incision, if there is exudation, redness, swelling, pain, etc., we should seek medical treatment in time; 2, after surgery, we should pay attention to functional exercise to prevent deep vein thrombosis. These patients are at high risk of thrombosis, so they should pay attention to the elevation of the affected limb and move down more often to promote venous return to avoid deep vein thrombosis; 3. V. Personal insight Hemangioma is the most common kind of benign tumor, and most of them do not need special treatment. Once the hemangioma is large, external stimulation or the patient’s own inattention may easily rupture and induce some other symptoms. In this case, the patient was considered to have a local hematoma caused by the rupture of hemangioma, which compressed the artery and led to the limitation of sensory-motor function, therefore, active surgical treatment is required. For patients with hemangioma, if the location is superficial and no complication is formed, they can be followed up and observed. If it invades deeper or appears thrombosis or bleeding, they should seek medical attention and actively perform surgical treatment, and most of the treatment results are good.
