ABSTRACT
Objective To evaluate the efficacy and safety of "outside-in" arthroscopic cam resection in the treatment of femoroacetabular impingement (FAI)syndrome.Methods Nine patients were treated with "outside-in" hip arthroscopy for cam or mixed type FAI syndrome between July 2015 and July 2016.All the 9 patients(11 hips)underwent osseous correction of the femoral neck and labral debridement.Before the surgery and 12 months after it,all patients were evaluated using the Harris Score and their complications were observed.Results The average postoperative Harris Score(92.5,range from 64 to 100)was significantly better compared with the preoperative one(56.4,range from 22 to 70,P＜ 0.001).One patient with blister on dorsal foot and another with fluid leakage were cured.No neurovascular injuries or cartilage injuries were found among all the patients.Conclusion "Outside-in" arthroscopic treatment of FAI with osseous correction and labral debridement is safe and effective.
ABSTRACT
Objective To summarize radiofrequency cather ablation (RFCA)of tachycardias with right sid-ed accessory atrioventricular pathway in 7 patients with persistent left superior vena cava (PLSVC). Methods RF-CA for right sided accessory atrioventricular pathway in 7 patients with PLSVC was carried out . Coronary sinus ac-cess was performed through the left subclavian and the left femoral vein respectively. Swartz sheath was used during ablation if neccesary. Results There was no siginificant differences in fluoroscopy time between the left subclavian approach and the left femoral vein approach[(2.8 ± 0.6)min vs (3.2 ± 0.3)min, P>0.05)]. No recurrence of ac-cessory pathway conduction was found during a mean follow-up of (23 ± 11) months. The mean discharging time and fluoroscopy time were (312 ± 67)s and (17 ± 5)min respectively. Conclusions Although RFCA of right sided accessory atrioventricular pathway in patients with PLSVC shows specialities in cather manipulation , mapping and ablation, high successful results can be achieved by experienced physician.
