Objective To explore rationale and clinical application of simplified modified radical thyroideetomy for differentiated thyroid carcinoma.Methods From Jan.2007 to Jun.2010,349 cases of differentiated thyroid carcinoma received simplified operative procedure based on standard modified radical thyroidectomy.The simplified procedure took a low small collar incision(about 10-12 cm).In separating upper and lower skin flaps,subcutaneous tissues covering posterior triangle of neck and posterior edge of sternoeleidomastoid muscle were spared to protect sensory nerves.Subtotal thyroidectomy Was performed to resect the affected lobe,isthmus,and the majority of opposite lobe without considering the size of primary tumor or whether metastasis to the neck lymph nodes happened.Soft tissues of the mainly metastatic areas(Ⅱ a、Ⅲ、Ⅳ、Ⅴb)were cleared.The accessory nerve was not exposed routinely to avoid stimulation.Lymph nodes metastasis in different areas was recorded respectively.Complications in different operative modes were compared.Results Compared with standard modified radical thyroidectomy,the simplified mode had shorter scar-and no limit of neck mobility.Because of muscles and nerves pemervation,movement dysfunction and abnormal sensation of neck and shoulder decreased obviously.The operation duration was shortened.Cervical lymph node status Was evaluated,which provided basis for prognosis judgment and comprehensive treatment.Conclusions The simplified modified radical procedure has the benefit of decreased trauma while maintains the similar recurrence rate compared to modified radical thyroidectomy.It improvs the life quality of patients.This procedure fits the principle of functional radical neck dissection better.

Objective:To evaluate the safety and efficacy of LVIS stent-assisted coil embolization in the acute phase of ruptured intracranial aneurysms.Methods:The clinical data of 55 patients with ruptured intracranial aneurysm treated with LVIS stent-assisted coil embolization admitted to Zhongshan Hospital of Xiamen University from January 2016 to December 2018 were analyzed retrospectively. The general data, the characteristics of aneurysms and the occurrence of perioperative complications of the patients were collected. The clinical prognosis of the patients at discharge and 6 months of follow-up was recorded. The Glasgow prognosis score (GOS) was graded as good (5), average (3-4), and poor (1-2), and the cerebral angiography results were recorded immediately after embolization and 6-month follow-up. The aneurysm occlusion was assessed by Raymond grade, Raymond Ⅰ was complete obliteration, Ⅱ was residual neck and Ⅲ was residual aneurysm.Results:All 55 patients received LVIS stent-assisted coil embolization within 72 hours of ruptured intracranial aneurysms, and all stents were released successfully, including 16 males (29.1%) and 39 females (70.9%). The median age was 53 (24-80) years old. Anterior circulation aneurysms were found in 49 patients (89.1%) and posterior circulation aneurysms in 6 patients (10.9%). According to Hunt-Hess classification, there were 43 patients with grade Ⅰ-Ⅱ (78.2%), 7 patients with grade Ⅲ (12.7%) and 5 patients with grade Ⅳ-Ⅴ (9.1%). The first digital subtraction angiography (DSA) examination of 55 patients after embolization showed that 41 patients had complete obliteration of aneurysms and 14 had residual neck; and the smaller the aneurysm was, the higher the rate of complete obliteration after embolization was. The proportion of small aneurysms (maximum diameter ≤ 7 mm) in the complete obliteration group was significantly higher than that in the neck residual group (100.0% vs. 64.3%, P < 0.01). Among the 55 patients, there was 1 patient suffered from in-stent thrombosis during embolization, 1 patient suffered from distal vascular thrombosis induced by plaque shedding during embolization, 1 patient suffered from vasospasm during embolization, and 1 patient suffered from postoperative distal cerebral hemorrhage after embolization. In 2 dead patients, 1 died of cardiogenic disease and 1 died of respiratory failure caused by severe pneumonia. At discharge, the prognosis was good in 40 patients, average in 10 patients, and poor in 5 patients; and the higher the Hunt-Hess grade at admission, the worse the prognosis. The proportion of patients with Hunt-Hess grade Ⅰ-Ⅱ at admission in the good prognosis group was significantly higher than that in the general prognosis group and the poor prognosis group (90.0% vs. 50.0%, 40.0%, P < 0.01). Of the 55 patients, 39 completed clinical prognosis and cerebral angiography 6 months after embolization for follow-up. All patients had GOS no less than 3, including 32 patients with complete obliteration of aneurysm, 4 with residual neck and 3 with residual aneurysm. The smaller the aneurysm, the higher the rate of complete obliteration at 6-month follow-up was. The proportion of small aneurysm in the complete obliteration group was significantly higher than that in the residual neck group and the residual aneurysm group (100.0% vs. 75.0%, 33.3%, P < 0.01). There was no rebleeding or ischemic complication at 6-month follow-up. Conclusions:LVIS stent assisted coil embolization is safe, effective and feasible in the acute stage of ruptured intracranial aneurysms. Standardizing antiplatelet therapy and dense packing of aneurysms during embolization are the key to reduce bleeding and ischemic complications.

Objective:To investigate the clinical efficacy in one stage reconstruction of composite defects of Achilles tendon and surrounding soft tissues with a flap transfer combined with allogeneic tendon transplantation.Methods:From July 2018 to August 2022, a total of 12 patients, including 9 males and 3 females, with a mean age of 31.5(ranged 8 to 56) years old, had surgery with flap transfer combined with transplantation of allogeneic tendon in one stage reconstruction for compound defects of Achilles tendon and soft tissue at the Department of Orthopaedics of First Affiliated Hospital of Nanchang University. The defects of Achilles tendons ranged from 4.0 to 9.0 cm, and the soft tissue defects sized from 3.0 cm × 4.0 cm to 14.0 cm × 6.0 cm. Of the 12 patients, 6 received transfers of sural neurovascular flaps, 3 with peroneal perforator flaps and 3 with free anterolateral thigh flaps(ALTF). The flaps sized from 4.0 cm × 4.5 cm to 15.0 cm×7.0 cm, and in addition, allogeneic tendon grafts were used to reconstruct the defects of Achilles tendons in all patients. All the flap donor sites were either directly sutured or covered with skin grafts. Follow-up was carried out by visits of outpatient clinic or telephone or WeChat distant interviews. The flap survival and recovery of ankle function and Achilles tendon were observed.Results:During the 3 months to 2 years of follow-up, none of the patient showed obvious immunological rejection against the transplanted allogeneic tendon. All 12 flaps survived well with the colour and texture close to the surrounding skin. No ulceration occurred in both of the donor and recipient sites. There was no re-rupture of the transplanted allogeneic tendon. At the final follow-up, ankle movement was measured at 13.4°±2.6° in dorsal extension and 33.6°±3.2° in plantar flexion. According to American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hind foot function score, a score of 88.7±5.6 was achieved with 7 patients in excellent, 4 in good and 1 was acceptable.Conclusion:In patients with a composite defect of Achilles tendon and surrrounding soft tissue, the application of a flap transfer combined with a homogeneous allograft tendon transplantation in an one stage surgery is a feasible surgical procedure. It can achieve a satisfactory outcome with less trauma and fewer complications.
