Blepharoplasty (Hotz operation) is a fre-quently used plastic surgery. The embedded-ligature technique was improved by the in-clusion of the M. levator palpebrae superiorisand orbicularis ocularis in the ligation afterthe ligatures being tied. It had the benefit ofbeing a reliable ligation with less operativerisk from loosening of the ligatures. It hadbeen used clinically in 40 cases, 23 of whichhad been followed from 3 to 16 months.Complication developed in 2 cases, the resthad a satisfactory results.
Objective To evaluate the surgical effects of indirect loop valvuloplasty of the superficial femoral vein plus superficial varicose veins stripping on primary deep venous valvular incompetence of the lower limb.Methods Seventy-eight patients (92 limbs) with primary deep venous valvular incompetence of the lower limbs received the operations of indirect loop valvuloplasty of the superficial femoral vein plus superficial varicose veins from 1997 to 2004. There were 65 males and 13 females, and their ages ranged from 32 years to 72 years (mean age of 52.5 years). The valvular reflux grades of these 92 limbs varied from Ⅲ to Ⅳ according to Kistner’s standard. A sleeve made from the stripped great saphenous vein was used in the indirect loop valvuloplasty of the superficial femoral vein. The early results of surgery were retrospectively analyzed. Results Pre-operative symptoms, such as edema, ulceration, pigmentation and heavy feeling of the performed limbs disappeared or were remarkably improved in 65 cases (76 limbs) after operation. Eight cases (10 limbs) had alleviative symptoms compared with pre-operative ones. Meanwhile, no improvement of symptoms was observed in 3 patients (4 limbs). Acute ilio-femoral vein thrombosis occurred in 2 patients (2 limbs), which manifested as more servious edema of the lower limbs than those before operation. The overall effective rate of surgery was 93.5%（86/92）, and the complications rate was 2.2% (2/92). Conclusion Indirect loop valvuloplasty of the superficial femoral vein plus superficial varicose vein stripping is an effective and convenient way to correct the primary deep venous valvular incompetence of the lower limb. The surgical indications of this disease should be emphasized strictly to assure the good outcomes.
Abstract： Compared with mitral valve replacement, there areseveral advantages in mitral valvuloplasty, so recently more and more sights are caught on mitral valve repair. According to different etiology, the surgeon can apply annuloplasty, triangular resection, quadrangular resection, replacement or transposition of chordae tendineae and so on to treat mitral regurgitation(MR). With the development of minimally invasive surgical technology, robotic mitral valve reconstruction evolve rapidly and percutaneous interventional therapy also commence from lab to bedside.We believe surgeons can repair MR safely and successfully in the majority of patients with proficiency in the basic techniques.
Objective To discuss shortterm effect of rotating hinge knee prosthesis. Methods From July 2002 to April 2005, 17 cases of severe knee joint deformity and instability received rotating hinge knee prosthesis for total knee arthroplasty. There were 8 males and 9 females, aging from 41 to 79 years. The left joints were involved in 10 cases and right joint in 7 cases. All patients were admitted because of pain. The course of disease was from 1 to 7 years. There were 10 cases of osteoarthritis，5 cases of rheumatoid arthritis，1 case of traumatic arthritis after operation of left femur fracture，and 1 case of traumatic arthritis with injury of anterior cruciate ligament, meniscus medialis and medial collateral ligament after operation of left fracture of tibial plateau. According to HSS(hospital for special surgery) scoring system，the preoperative score was 36 to 58 with an average of 48.6. The preoperative flexed motion range of articulation was 21° to 80° with an average of 57.4°. Results All patients were followed up from 7 months to 3 years with an average of 23.6 months. There were no complications of thrombogenesis of veins of lower extremity, pulmonary embolism, palsy of peroneal nerve, fracture, and breakage of extended knee structure. Infection occurred in 1 case at 3 months postoperatively，the prosthesis was dislodged，antibiotic-impregnated cement was filed with knee joint，twostage arthroplasty was expected. At the last follow-up,the HSS score was 78 to 98 with an average of 91.1 in 16 patients. The flexed motion range of articulation was 75° to 100° with an average of 852° at 2 weeks postoperatively. The flexed motionrange of articular was 85° to 123° with an average of 1083° at the last followup. There were significant differences in HSS score and motion range of articular between preoperation and thelast follow-up (P＜0.05). Conclusion The short-term outcome of rotating hinge knee prosthesis is good and a long term followup is necessary.
ObjectiveTo compare the clinical efficacy and safety between percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral compression fracture (OVCF) with intravertebral vacuum cleft (IVC). MethodsBetween January 2010 and December 2013, 68 patients with single OVCF and IVC were treated, and the clinical data were retrospectively analyzed. Of 68 patients, 48 underwent PVP (PVP group) and 20 underwent PKP (PKP group). There was no significant difference in age, gender, disease duration, fracture level, bone mineral density (BMD), visual analogue scale (VAS), Oswestry disability index (ODI), and preoperative radiological parameters between 2 groups (P > 0.05). The intraoperative incidence of cement leakage, cement volume, and operative time were compared between 2 groups; VAS score was used for evaluation of back pain and ODI for evaluation of dysfunction; the incidence of adjacent vertebral fracture was observed within 2 years. The vertebral height and kyphotic angle were measured on X-ray films; the rate of vertebral compression (CR), reduction rate (RR), progressive height loss (PHL), reduction angle (RA), and progressive angle (PA) were calculated. ResultsThere was no significant difference in cement volume and the incidence of cement leakage between 2 groups (P > 0.05). The operative time in PVP group was shorter than that in PKP group, showing significant difference (t=-8.821, P=0.000). The mean follow-up time was 2.4 years (range, 2.0-3.1 years). The VAS scores and ODI were significantly reduced at 1 day, 1 year, and 2 years after operation when compared with preoperative scores (P < 0.05), but there was no significant difference between different time points after operation in 2 groups (P > 0.05). Adjacent vertebral fracture occurred in 5 cases (10.4%) of PVP group and in 2 cases (10.0%) of PKP group, showing no significant difference (χ2=0.003, P=0.963). BMD was significantly increased at 1 year and 2 years after operation when compared with preoperative BMD (P < 0.05), but no significant difference was found between 2 groups (t=0.463, P=0.642; t=0.465, P=0.646). The X-ray films showed that CR and kyphotic angle were significantly restored at immediate after operation in 2 groups (P < 0.05); but vertebral height and kyphotic angle gradually aggravated with time, showing significant difference between at immediate and at 1 and 2 years after operation (P < 0.05); there was no significant difference in CR and kyphotic angle between 2 groups at each time point (P > 0.05). RR, RA, PHL, and PA showed no significant difference between 2 groups (P > 0.05). ConclusionThere is similar clinical and radiological efficacy between PVP and PKP for treatment of OVCF with IVC. Re-collapse could happen after operation, so strict observation and follow-up are needed.
ObjectiveTo observe the effects of carotid artery stenting (CAS) on ophthalmic artery blood flow in patients with ischemic ophthalmopathy (IOP).MethodsA prospective case-control study. Sixty IOP patients (60 eyes) who met inclusive criteria for CAS were enrolled in this study. There was 50% stenosis of internal carotid artery on one side at least confirmed by color doppler flow imaging (CDFI). Among 60 eyes, there were 3 eyes with central retinal artery occlusion, 15 eyes with retinal vein occlusion, 37 eyes with ischemic optic neuropathy, 5 eyes with ocular ischemia syndrome. The patients were randomly divided into CAS group (32 eyes of 32 patients) and medicine therapy group (28 eyes of 28 patients). The difference of age (t=1.804) and sex (χ2=1.975) between two groups was not significant (P＞0.05). The examinations of fundus fluorescein angiography (FFA), CDFI and digital substraction angiography (DSA) were performed before, 1 week and 6 months after treatment. The following parameters were recorded: arm-retinal circulation time (A-Rct), peak systolic velocity (PSV), end-diastolic velocity (EDV), and resistance index (RI) in the ophthalmic artery (OA) and central retinal artery (CRA), and the best corrected visual acuity (BCVA).ResultsThere was no significant differences in A-Rct (t=1.354) and BCVA (t=0.376) between the two groups before treatment (P＞0.05). Also, there was no significant differences in PSV (t=−0.294, −2.446), EDV (t=0.141, −0.305), and RI (t=−0.222, −0.694) of OA and CRA between the two groups before treatment before treatment (P＞0.05). Compared with the medicine therapy group, the lower A-Rct was found in the CAS group at different time points after the treatment. The difference was significant on 1 week after treatment (t=−3.205, P＜0.05), but not on 6 months after treatment (t=1.345, P＞0.05). The BCVA of eyes in the two groups were increasing with the extending of time of therapy. Compared with the medicine therapy group, the better BCVA was found in the CAS group at different time points after the treatment (t=0.800, 1.527; P＜0.05). Compared with the medicine therapy group, the higher PSV, EDV and lower RI of OA and CRA were found in the CAS group at different time points after the treatment. (P＜0.05).ConclusionCompared with conventional medicine therapy, CAS shows earlier effects in improving ocular hemodynamics for IOP patients with carotid artery stenosis, which benefits visual function improvement of the patients.
