Objective To study the feasibility,safety,and efficacy of hysteroscopic treatment of submucous leiomyomas and endometrial polyps.Methods Hysteroscopic resections were performed in 38 cases of submucous leiomyomas and 40 cases of endometrial polyps from January 2002 to July 2004,including 31 cases of transcervical resection of myoma(TCRM),7 cases of TCRM combined with transcervical resection of the endometrium(TCRE), 35 cases of transcervical resection of polyp(TCRP),and 5 cases of TCRP combined with TCRE.Results The operation was completed smoothly on one session in all the 78 cases.The intraoperative blood loss was ≥ 400 ml in 2 cases.There were 1 case of overhydration.No uterine perforation or infection occurred after operation.The patients were followed at 1,3,6,and 12 months after operation,respectively,and the surgical outcomes were assessed at 12 postoperative months.Follow-up findings revealed 8 cases of amenorrhea(10.3%),12 cases of irregular spotting(15.4%),33 cases of hypomenorrhea(42.3%),22 cases of normal menstrual flow(28.2%),and 3 cases of no improvement(3.8%).Conclusions Hysteroscopic resections for submucous leiomyomas and endometrial polyps offer advantages of good reliability and fewer complications,being worthy of recommendation.

Twenty seven patients with obstruction of three branches below popliteal artery were divided into three groups and treated with three different kinds of arterioveinous reversal randomly. The results show that it is better to rebuild ischemic limb circulation with original vein rearterization on the femoral and popliteal planes than to do on the lower deep groups and original great saphenous rearterization for improving symptoms immediately and blood flow at future. It provides a new operation for obstruction of three branches below popliteal artery caused by thromboangiitis obliterans,arteriosclerosis obliterans and other diseases.

Objective To evaluate the clinical effect and application value of internal fixation of Magerl combined with Brooks technique for atlantoaxial instability. Methods A total of 18 patients with atlantoaxial instability, reducible atlantoaxial dislocation with reduction after traction and irreducible atlantoaxial dislocation with traction reduction after anterior laxation were treated with internal fixation of Magerl combined with Brooks technique using autologous bone grafts. Results The patients were followed up for an average 18 months (6-36 months). Screw was probably cut into the vertebral artery in one case. The guide needle was cut into the pharynx due to incorrectly penetrating the C 1 anterior arch of atlas for 3.5 cm in one case but no early complications such as spinal cord injury and local infection occurred. The spinal cord function improvement was marked in 3 cases, good in 9, mild in 4 but unchanged in 2. No case got worse. There were no loosening or break of the screw and cable. Conclusions Combined fixation of Magerl and Brooks techniques reaches three-point fixation and improves the reduction effect. It is necessary to use the combined fixation with best biomechanical stability for atlantoaxial dislocation patient with reduction or near reduction if the structure of the posterior arch of C 1,2 is intact.

Objective To summarize the experience of preventing infection in atlanto-axial operations via transoropharyngeal approach. Methods The methods and experiences of prevention of infection in 80 cases of atlanto-axial dislocation operated on via transoropharyngeal approach were retrospectively summarized and analyzed. Result There was no infection in all the 80 cases. Conclusion As long as preventive measures were perfectly taken, the post-operative infection could be effectively prevented and the transoropharyngeal operation would be safe.

Objective To evaluate the clinical results of subtotal vertebrectomy of the axis for spinal canal decompression by transoral anterior approach in the treatment of atlanto-axial dislocation with spinal cord compression. Method fifteen cases of atlanto-axial dislocation with spinal cord compression caused by congenital deformity or trauma were subjected to subtotal vertebrectomy of the axis via transoral anterior approach . Results After an average follow-up of 20 months, curative effect was evaluated according to Symon and Lavender. Vertebral canal vector diameters in MRI were measured. The total clinical effective rate was 100%, and the remarkable effective rate reached 60%. The average improvement rate of vertebral canal decompression was 79.8%. No sign of spinal cord and arteries injury and infection were observed. Conclusion Subtotal vertebrectomy of the axis via transoral anterior approach is proved to be feasible to treat cervical spinal cord compression on C 2 vertebra level.

Objective To explore the follow‐up value of ultrasound in fetal tricuspid regurgitation . Methods 44 fetuses who presented with moderate tricuspid regurgitation with differential pressure over 20 mmHg ,dilation of right atria and ventricles were chosen as the observation group .Examinations ,in terms of the degree ,velocity and differential pressure of reflux ,size of heart chamber and the presence pericardial or pleural effusion were carried out once every four weeks from 24 weeks of pregnancy to 9 weeks after birth . Results 40 9.% (18/44) of cases had been getting better before birth .The degree of regurgitation of 56 8.%(25/44) cases significantly decreased or even disappeared from 1 to 62 days after birth .Especially ,3 cases whose regurgitation velocity reached to 4 2. m/s with the differential pressure over 70 mmHg as well as onset of heart failure symptoms had been recovered gradually after born in advance 1. case (2 3.% ) with the persistence of both tricuspid regurgitation and heart failure symptoms after birth died in right heart failure , even though using different active treatments ,such as oxygen ,strong heart and diuresis .Conclusions High‐speed tricuspid regurgitation in fetuses without pathological changes can be almost reversed ,and the prognosis is good .Once the fetal tricuspid regurgitation pressure is over 70 mmHg or a fetus appears the onset of heart failure symptoms ,pre‐term delivery should be advised in a bid to prevent accidents in uterine cavity .
