Objective To observe the incidence and related factors of macula hole retinal detachment（MHRD）after phacoemulsification cataract extraction and intraocular lens（IOL）implantation. Methods The clinical data of 10 076 patients(13 625 eyes) who underwent phacoemulsification cataract extraction and intraocular lens implantation were retrospectively analyzed. There are 1228 patients (1853 eyes) with high myopia. All the patients were examined by routine slitlamp microscopy, ophthalmoscopy as well as A- or B-scan ultrasonography. The phacoemulsification cataract extraction with transparent cornea incision or scleral tunnel incision, combined with intraocular lens implantation was performed in all the patients. The followup was ranged from 12 to 126 months, with a mean of （48.2plusmn;31.1）months. The MHRD was confirmed by the examinations of the fundus, B-scan ultrasonography and optical coherence tomography. The incidence of postoperative MHRD and the risk factors were analyzed. Results 10/13 625 eyes (0.073％) with MHRD were observed. 7/1853 high myopia eyes (0.378%) with MHRD were observed. The occurrence time of MHRD was ranged from 9 to 74 months after surgery, with a mean of 38.5 months. The cumulative risk was estimated at 0.16％ (95% confidence interval, 0.05% -0.27%).Conclusions The incidence of MHRD after phacoemulsification cataract extraction combined with intraocular lens implantation is 0073%. The MHRD incidence of high myopia eyes is 0.378%. High myopia may be the risk factor for MHRD.
ObjectiveTo analyze the short-term and long-term efficacy of staged coronary artery bypass grafting (CABG) and carotid artery stenting (CAS) compared with CABG alone in patients with coronary heart disease with preoperative history of stroke and carotid stenosis. MethodsWe reviewed the clinical data of 55 patients (48 males, 7 females, aged 67.62±7.06 years) with coronary heart disease and carotid stenosis who had a history of stroke and underwent CABG+CAS or CABG alone in Zhongshan Hospital from 2008 to 2017. There were 13 patients in the staged CABG+CAS group and 42 patients in the CABG alone group. The differences in the incidence of perioperative adverse events and long-term survival between the two groups were studied, and univariate and multivariate analyses were carried out to determine the independent risk factors of long-term adverse events. Results Perioperative adverse events occurred in 1 (7.69%) patient of the staged CABG+CAS group, and 4 (9.52%) patients of the CABG alone group (P=0.84). During the follow-up period (67.84±37.99 months), the long-term survival rate of patients in the staged CABG+CAS group was significantly higher than that in the CABG alone group (P=0.02). The risk of long-term adverse events in the staged CABG+CAS group was 0.22 times higher than that in the CABG alone group (95%CI 0.05-0.92, P=0.04). ConclusionStaged CABG+CAS can significantly improve the long-term survival prognosis without increasing the perioperative risk. It is a safe and effective treatment, but prospective randomized studies are still needed to further confirm this finding.
Objective To discuss the key points of anesthesia for patients undergoing transcatheter aortic valve implantation (TAVI) surgery. Methods We retrospectively collected and analyzed the data of 70 patients who underwent TAVI in the Department of Cardiovascular Surgery, West China Hospital from March 2014 to October 2015. There were 39 males and 31 females with an average age of 73.7±4.5 years. The perioperative preparation and anesthesia points of TAVI were summarized. Results All of the 70 included patients were aged and at high risk severe comorbidities such as ischemic heart disease and stroke. The aortic stenosis and regurgitation occurred in 39 and 31 patients respectively. No patients died during the surgery. The total success rate was 95.7%. Conclusion TAVI is a complex procedure for high risk patients and need more attention during anesthesia. The successful conduction of the procedure requires the whole team to prepare carefully and cooperate closely.
Objective To observe the clinical characteristics and therapeutic effect of aphakic retinal detachment (ARD) eyes and pseudophakic retinal detachment (PPRD) eyes.Methods The clinical data of 805 patients,including 321 ARD and 484 PPRD eyes were retrospectively analyzed.The patientsprime;visiual acuity, refraction, intraocular pressure were examined, and the patients also underwent slit lamp microscopy and direct and (or) indirect ophthalmoscopy.The preoperative bestcorrected visual acuity (BCVA) was between light perception (LP) and 0.6.Mainly according to the PVR grade and retinal holes position to take the scleral buckling or vitrectomy combined with scleral buckling. The 805 eyes were divided into 1995-1999 group (243 eyes) and 20002007 group (562 eyes) according to operative time.The follow-up ranged from 3 to 25 months, with an average of 12.3 months.The success standard of surgery was set as anatomic retinal reattachment and the last follow-up time was considered as the judgment time.The surgical complications were recorded at each followup time points. The composition of PPRD,the visual acuity,ocular lesions, surgical methods and results before operation and visual acuity after operation in two groups were analyzed and compared by MantelHaenszel chisquare test. Results The average interval from lens extraction to RD occurrence was 15.4 months in PPRD eyes and 39.1 months in ARD eyes. The final total anatomic success rate was 95.9%, and was 93.5% in the scleral buckle eyes and 97.2% in vitrectomy eyes.The BCVA was better than 0.3 after operation only in 11.9% of the 805 patiens,and the visual acuity increased more than 2 lines in 67.3%. Compared with the ARD eyes,early onset, high proportion of total posterior vitreous detachment,severe PVR,wide RD range,low detection rate of retinal hole and low antomic success rate were found in PPRD eyes.Compared with the 1995-1999 group,the proportion of vitreous surgery,anatomic success rate and better visual acuity were found in 2000-2007 group.Conclusions The ocular lesions of ARD and PPRD is more complicated,the therapeutic effect are improving in recent years.
For patients with aortic valve disease who require replacement of their native valve, surgical aortic valve replacement (SAVR) has been the standard of care. Due to the hemorrhage and thromboembolic risks of long-term anticoagulation therapy for mechanical prosthesis, bioprosthetic aortic valve replacement (AVR) has a trend to be used in younger patients, which raising the concern for the durability of bioprosthetic valves. The newly published 5-year outcomes of PERIGON trial, with no structural valve deterioration, again demonstrated the favorable durability of the new generation bioprosthetic valves, further providing the evidence of using bioprosthetic AVR in younger patients. At the meantime, the rapid progress of transcatheter aortic valve implantation (TAVI) has brought a new treatment option. For younger patients with low risks, choosing SAVR or TAVI becomes a critical decision. This paper reviews the outcomes of PERIGON trial and its implications to the clinical practice and research of bioprosthetic AVR.
Objective Surgical repair for giant lower ventral hernia is facing challenge owing to enormous tissue defect and the critical structures of pubis and il iac vessels. To investigate the method and curative effect of intraperitoneal onlay mesh (IPOM) combined with Sublay for compound repair of giant lower ventral hernia. Methods Between November 2008 and August 2010, 26 patients with giant lower ventral hernia were treated. There were 15 males and 11 females with an averageage of 61 years (range, 36-85 years), including 11 cases of lower midl ine incisional hernia due to radical rectal procedures, 6 cases of Pfannenstiel incisional hernia due to radical uterectomy, and 9 cases of lower midl ine incisional hernia due to radical cystectomy. Of them, 11 patients underwent previous repair procedures. The mean time from hernia to admission was 8.5 years (range, 1-15 years). All hernias were defined as M3-4-5W3 according to classification criteria of Europe Hernia Society. The mean longest diameter was 17.5 cm (range, 13-21 cm) preoperatively. Before 2 weeks of operation, abdominal binder was tightened gradually until the contents of hernia sac were reduced totally, and then reconstruction of abdominal wall was performed with compound repair of IPOM and Sublay technique. Results All of compound repair procedures were performed successfully. The mean hernia size was 112.5 cm2 (range, 76.2-160.6 cm2); the mean polypropylene mesh size was 120.4 cm2 (range, 75.3-170.5 cm2); and the mean compound mesh size was 220.0 cm2 (range, 130.4-305.3 cm2). The mean operative time was 155.5 minutes (range, 105.0-195.0 minutes) and the mean postoperative hospital ization time were 12 days (range, 7-16 days). Incisions healed by first intention; 4 seromas (15.4%) and 3 chronic pains (11.5%) occurred and were cured after symptomatic treatment. All patients were followed up 3-24 months (mean, 14.5 months). No recurrence and any other discomforts related to repair procedure occurred. Conclusion Compound repair of IPOM and Sublay is a safe and efficient surgical procedure for giant lower ventral hernia, owing to its characteristics of adequate patch overlap and low recurrence rate. Perioperative management and operative technology play the key role in the success of repair procedure.
