Objective To summarize the experience of surgical treatment for 84 patients with aortic dissection, investigate the surgical technique and perioperative treatment, and to improve surgical results. Methods The operations were performed in 50 patients with aortic dissection of Stanford A， Bentall or Cabrol operations were performed in 24 patients, graft replacement of ascending aorta in 8 patients, Trusler operation in 5 patients, Wheat operation in 5patients, operation of ascending aorta and aortic arch in 8 patients.Stentgraft were used in 34 patients with aortic dissection of Stanford B. Results There were 11 hospital death,the hospital mortality was 13.1%.There were 3 operative deaths.One patient with ascending aortic and hemiarch grafting died of aortic root bleeding;one patient with replacement of ascending aorta died of failure to restart heart beating；one patient with ascending aortic and hemiarch grafting died of rapture of aortic dissection. There were 8 postoperative deaths, including low cardiac output syndrome in 2 patients, lung infection in 2 patients, renal failure in 2 patients， respiratory failure in 1 patient and permanent mental anomaly in 1 patient. The complications were occurred in 16 patients. The followup period was 3 months to 10 years, and carried out in 62 patients（84.9%，62/73).One died of endocarditis, another one died of sudden death. Conclusion The surgicaltreatment of aortic dissection could be carried out safely based on the accurate diagnosis， specific surgical strategy and fine surgical technique.
Objective To investigate the diagnosis, indications for surgery, operative methods and prognostic factors of surgical resection for pulmonary metastases, and improve the survival rate of patients with pulmonary metastases . Methods A total of 125 patients with pulmonary metastases underwent 138 metastasectomies,116 patients had metastasectomy once while 5 patients underwent a second metastasectomy and 4 patients a third metastasectomy. There were 66 wedge resections,2 segmentectomies, 53 lobectomies,2 en bloc resections of chest wall plus lobectomy,3 pneumonectomies and 12 precision resections. Surgical approaches included 130 thoracotomies and 8 videoassisted thoracic surgery. Results The primary tumor sites were epithelial in 94 patients ,sarcoma in 26 and others in 5. There was no perioperative mortality. A total of 122 patients were followed up , followup time was 1-10 years. The 1-, 3-, and 5-year survival rates were 90.4%, 53.3%, and 34.8% respectively. Better prognoses were found in patients with colorectal cancer, renal cancer and soft tissue sarcoma, the 5-year survival rates were 43.8%, 37.5%, and 33.3% respectively. For the 105 patients whose pulmonary metastases were resected completely, the 5-year survival rate was 38.9%. The 5-year survival rate was only 16.7% for 20 patients with incomplete resection, however. Systematiclymph node dissection had been performed in 89 patients but metastases were identified only in 12 patients. The 5-year survival rates were 14.3% for node positive patients and 41.5% for node negative patients. Conclusion Surgical resection for pulmonary metastases should be performed in properly selected patients and successful outcomes can be achieved. Posterolateral minithoracotomy is the most common surgical approach. The completeness of resection and the status of mediastinal lymph nodes may be important prognostic factors.
Objective To investigate diagnosis and surgical management of femoral head osteonecrosis in sickle cell disease(SCD). Methods The related literature available today was reviewed, and the clinical advance in the diagnosis of femoral head osteonecrosis complicating SCD and its surgical management was evaluated. Results Although the advance in the diagnosisand the surgical treatment for the femoral head osteonecrosis in SCD had been achieved, challenging clinical problems still remained because of many complications after the surgical treatment. Whether the surgical management was reasonablein a particular stage of the disease and for a specific patient still required investigation. Conclusion Whether the salvage of the patient’ship joint should be performed or the artificial joint replacement should be performed still needs a cautious consideration before either of the surgical managements is given.
Objective To study the surgical method to reduce bleeding in treating hemangioma at non-limb sites. Methods From November 1998 to November 2003,49 cases of non-limb hemangioma were treated, aged 3 months to 63 years, including 21 males and 28 females. There were 14 cases of capillary hemangioma, 25 cases of cavernous hemangioma, 7 cases of arterial racemose angioma and 3 cases of mixture hemangioma. According to the position and type of hemangioma, the various methods of blocking blood vessels were adopted to assist resect tumors. Afterthe pulsatile artery was felt in arterial racemose angioma of neck and face by palpation, we sutured and knotted it with 7-0 silk string to block the bleeding.We found out the common iliac artery or external iliac artery or femoral arteryand blocked them temporarily to resect arterial racemose angioma in inguen and thigh. We sutured and knotted vessel with 7-0 silk string to block the bleedingin capillary hemangioma and cavernous hemangioma of neck and face and truncus. Results Intraoperative bleeding obviously decreased and the tumor size reducedto various extent. Of the 49 cases, 47 cases achieved complete success, 2 casesbled within two days after operation. A postoperative follow-up of 6 months to4 years showed that the appearance and function were satisfactory. Conclusion The preoperative method of blocking blood vessels obviously can reduce intraoperative bleeding and decrease operative difficulty, which makes it possible to eradicate hemangioma and lower recurrence rate.
