Objective To summarize the visual outcome of patients with severe ocular trauma treated with vitreous surgery. Methods Clinical data of 188(191 eyes) with severe ocular trauma treated with vitreous surgery in a period from November 1996 to April 1998 were analysed retrospectively. Results The study included penetrating injury in 56 eyes, foreign bodies in the posterior segment in 70 eyes, blunt injury in 41 eyes , and globe rupture in 24 eyes. Main complications included endophthalmitis in 35 eyes, choroidal bleeding in 20 eyes, retinal detachment in 60 eyes, and vitreous hemorrhage in 97 eyes. Post-opera-tively, out of 188 eyes, except for 3 of patients too young to examine, visual acuity improved in 133(70.7%), including 85(45.2%) with visal acuity 0.02-1.0, 46(24.5%) remained unchanged; and 9(4.8%) had worse vision. Among 34 with no-light-perception, 12 had light-perception or over. Conclusion A majority of severe trauma eyes can be salvaged with considerable visual recovery after adequate and timely vitreous surgery. (Chin J Ocul Fundus Dis,1999,15:4-6)

Objective To summarize the characteristics and management of pregnancy complicated with aortic dissection, and to explore the reasonable diagnosis and treatment plan. Methods The clinical data of 10 patients of pregnancy complicated with aortic dissection in Wuhan Tongji Hospital from January 2011 to June 2017 were collected. Their age was 25.2 (21-29) years. Results In the 10 patients, the majority (8 patients) were primipara, and most of them were in the late stages of pregnancy (5 patients) and puerperal (4 patients). Among them, 1 patient had gestational hypertension, and the blood pressure of the left and right upper extremities was significantly abnormal (initial blood pressure: left upper limb blood pressure: 90/60 mm Hg, right upper limb blood pressure: 150/90 mm Hg). The major clinical manifestations were severe chest and back pain which happened suddenly, with D-dimmer and C-creative protein increased which may be associated with inflammatory reaction. All patients were diagnosed by thoracoabdominal aortic CTA, including 5 patients of Stanford type A dissection and 5 patients of Stanford type B dissection. In the 10 patients, 1 patient refused surgery and eventually died of aortic rupture with the death of fetus before birth. And the remaining 9 patients underwent surgical treatment, 3 patients of endovascular graft exclusion for thoracic aortic stent graft, 2 patients underwent Bentall operation, 1 patient with Bentall + total aortic arch replacement + vascular thoracic aortic stent graft, 1 patient with Bentall operation combined with endovascular graft exclusion for thoracic aortic stent graft, 1 patient with Bentall + coronary artery bypass grafting, 1 patient of thoracoabdominal aortic vascular replacement. Among them, 1 patient underwent endovascular graft exclusion for thoracic aortic stent graft died of severe postoperative infection, and the remaining 8 patients were discharged from hospital. Nine patients were single birth, among them 5 newborn patients had severe asphyxia, 4 patients had mild asphyxia. Finally, 3 neonates died of severe complications, and the remaining 6 survived. Conclusion The ratio of pregnancy with Stanford type A aortic dissection is far higher than in the general population, the possibility of fetal intrauterine asphyxia is larger, but through active and effective surgical and perioperative treatment, we can effectively save the life of mother and fetus.
ObjectiveTo summarize the research progress of near infra-red fluorescence imaging (NIRFI) in biliary tract surgery, and to provide protection for improvements of therapeutic effect and safety of biliary tract surgery.MethodThe relevant literatures about studies on NIRFI in the biliary tract surgery in recent years were reviewed.ResultsThe NIRFI had been preliminarily used in the surgical treatment of benign and malignant biliary diseases, and had shown its unique value in cholangiography. It provided a new method for effectively avoiding surgical complications, shortening operation time, reducing the rate of conversion to open surgery, evaluating blood supply of bile duct and improving the safety of operation.ConclusionsNIRFI has achieved notable successes in treatment of biliary tract diseases. With future application of fluorescence imaging in near infra-red Ⅱ window and new specific fluorescence targeting molecules, this technique will highlight its more important values in biliary surgery.
Objective To explore the clinical effect of different types of free tissue transplantation on repairing tissue defects and reconstructing functions. Methods From November 2001 to September 2004, 14 types of freetissue transplantation and 78 free tissue flaps were applied to repairing tissue defects and reconstructing functions in extremities and maxillofacial region in 69 cases. Of the 69 cases, there were 53 males and 16 females (their ages ranged from 18 to 56, 31 on average). Five cases were repaired because of skin defects in foot, 22 cases were repaired because of skin defects in leg, 36 cases were repaired as the result of skin defects in hand or forearm and finger reconstruction, 3 cases were restored by virtue of ulna or radius defects, and 3 cases were repaired in maxillofacial region. There were 55 cases of open wound, in which 16 cases were infectious wound, 6 cases were osteomyelitis or pyogenic arthritis. There were 14 cases of noninfectious wound. The area of these tissue flaps ranged from 2.0 cm×1.5 cm to 43.0 cm×12.0 cm. The length of bone transplantation ranged from 10 cm to 15 cm. Results Arterial crisis occurred in 2 cases, venous crisis occurred in 2 cases.Seventysix flaps survived completely and 2 flaps survived partially which werelater healed. Fiftytwo cases were healed at stageⅠ, 13 cases were healed at stageⅡ(healing time ranged from 20 to 30 days), purulent infection occurred to 4cases(healing time ranged from 3 to 11 months). Bone healing time ranged from 6 to 8 weeks in finger reconstruction. Bone healing time ranged from 4 to 6 months in fibula transplantation. The function reconstruction and appearance were satisfying. The functions of all regions, where free tissues were supplied, were not disturbed. Conclusion Tissue transplantation and composite tissue transplantation are effective in repairing tissue defects and reconstructing functions.
ObjectiveTo summarize the diagnosis and treatment of thoracoomphalopagus conjoined twins according to successful separation of two cases of conjoined twins. MethodsA retrospectives study was performed on two pairs of thoracoomphalopagus twins. One case was omphalopagus with complex congenital heart disease (transposition of the great arteries and single cardiac ventricle), and the other was sternoxiphopagus with single pericardium and complex congenital heart disease (single cardiac ventricle and cardiac atrium). All the two cases of conjoined twins shared the common livers. The separation surgery was performed at one month after birth. Results All the two cases of conjoined twins were successfully separated. These conjoined twins were connected by a liver bridge, and shared a pericardium or had a contact pericardium, respectively. The coloboma of peritoneum, diaphragm， and mediastinum were repaired by Gore-Tex patch. Each patient, to varying degrees, had a wound infection after surgery, and healed by taking out the Gore-Tex, debridement or drainage. The first two infants were discharged on 37 d after operation, but one died of pneumonia after 6 months. The two other infants were discharged on 40 d and 93 d after operation, respectively. ConclusionsDetailed information about the twins’ general and conjoined condition, especially on cardiovascular system and the joined liver, shall be understood by the imagination examinations before the operation. Adequate preoperative preparation, elaborate liver separation and rational reconstruction for thoracic and abdominal wall are the key to successful operation.
Since 1979, vascularized iliac bone graft based on the deep circumflex iliac vessels (DCIV) or the deep superior branches of superior gluteal vassels (SGV) was used to the treatment of bone defect, non-union of fracture, and aseptic necrosis of the femoral head in Ⅱ4 cases. Of these Ⅱ4 graftings, 68 were pedicled, 46 were microvascular free transfer. Early callus formation developed 6 weeks after surgery. Solid bony union was obtained in 3 months. Among 32 patients with aseptic necrosis of femoral head followed more tha 1 years, dior relief of pain and omprovement of X-ray findings were obtained in 31. The advantages of using vascularized iliac bone graft, especially based on the DCIV and SGV, are discussed. The author has a good opinion of vascularized iliac bone graft based on the SGV.
Objective To evaluate the effectiveness and safety of 25G illumination aided scleral buckling surgery for treatment of rhegmatogenous retinal detachment (RRD). Methods This is a retrospective case control study. Fifty-seven RRD patients (57 eyes) were enrolled in this study. There were 35 males (35 eyes) and 22 females (22 eyes). The patients were randomly divided into ophthalmoscope group (29 patients, 29 eyes) and illumination group (28 patients, 28 eyes). There was no differences in the data of gender, age, onset time, logarithm of the minimum angle of resolution (logMAR) best corrected visual acuity(BCVA) and information of retinal tears between the two groups (P＞0.050). The patients in the ophthalmoscope group received operation of conventional scleral buckling with binocular indirect ophthalmoscope. The patients in the illumination group received scleral buckling surgery with the aid of intraocular illumination and noncontact wide-angle viewing system. The follow-up was ranged from 6 to 12 months. The BCVA, intraocular pressure, fundus examination and complications were observed and recorded. Results The difference of operation time between two groups was significant (t=2.124, P=0.031). In the ophthalmoscope group, 26 eyes (89.7%) achieved retinal reattachment, 3 eyes (10.3%) failed in retinal reattachment. In the illumination group, 26 eyes (92.8%) achieved retinal reattachment, 2 eyes (7.2%) failed in retinal reattachment. There was no difference of retinal reattachment rate (P=1.000). Five eyes failed in retinal reattachment, 3 eyes received sclera buckling surgery, 2 eyes received vitrectomy with silicone oil tamponade. The final reattachment ratios were both 100%. BCVA increased in both groups compared with pre-surgery BCVA (t=4.529, 5.108; P＜0.001). The difference of BCVA between two groups was not significant (t=0.559, P=0.458). There was no significant difference of intraocular pressure and complications before and after surgery in both two groups (t=−1.386, −1.437; P=0.163, 0.149). The difference of intraocular pressure between two groups was not significant (t=0.277, P=0.730). Subretinal hemorrhage occurred in 1 eye in the ophthalmoscope group. There was no iatrogenic retinal break, choroidal hemorrhage and endophthalmitis in the two groups. Conclusion 25G intraocular illumination aided buckling surgery for treatment of RRD is fast, safe and effective.
