Objective To observe the clinical characteristics of gestational diabetic retinopathy (DR)of 13 pregnants with vitreous hemorrhage.Methods The clinical data of 26 eyes retinopathy with 13 cases of gestational diabetes were retrospectively analyzed.After bilateral eyes were mydriatic by Pyrazole MAO amine compound,ophthal-mologist used fundus camera to check bilateral fundus.B ultrasonic was used to examine vitreous hemorrhage and the surfaces of vitreous and retinal.Results In 13 cases,26 eyes vision were between hand motion-0.6.Sudden vitre-ous hemorrhage in 13 eyes,accounted for 50.0%(13/26).Among them,the classⅠvitreous hemorrhage in 10 eyes, 76.9%(10/13).Ⅱ,Ⅲ grade vitreous hemorrhage in 2 eyes,15.4%(2/13).LevelⅣvitreous hemorrhage in 1 eye, accounted for 7.7%(1/13).26 eyes were diagnosed with stage IV(early or fiber hyperplasia period)DR.The fundus photography:the size,number of retinal neovascularization were found in 13 eyes without vitreous hemorrhage.Ultra-sound confirmed that the 13 eyes vitreous hemorrhage were fresh bleeding,and found 4 eyes with fiber membrane, accounted for 30.8%(4/13).The eyes without vitreous hemorrhage were timely treated by laser,and the eyes with vitreous hemorrhage were treated by stage laser treatment according to the condition of vitreous hemorrhage absorp-tion.Followed up for 4 to 6 months,in a stable condition.Conclusion Obstetrics and gynecology doctors and oph-thalmologists should pay attention to pregnancy DR with vitreous hemorrhage.Because they are all early or fiber hyper-plasia period.Timely and reasonable laser treatment can prevent permanent damage of visual function.

Objective To evaluate the short-term results of sleeve wrapping technique using remnant aortic wall in modified Bentall procedure. Methods The patients undergoing modified Bentall procedure with the remnant aortic wall as a sleeve to cover the sewing area of composite valved graft and the aortic annulus for proximal hemostasis between March 2021 and March 2022 in Shenzhen Fuwai Hospital were enrolled. Short-term results were assessed by cardiopulmonary bypass time, aortic clamping time, mechanical ventilation time, ICU stay, postoperative hospital stay, effusion drainage on the first postoperative day, left ventricular ejection fraction (LVEF), left ventricular end diastolic diameter (LVEDD), and follow-up results. Results A total of 14 patients were collected, including 12 males and 2 females, with a mean age of 55.33±10.57 years. There was no postoperative or follow-up death. Cardiopulmonary bypass time was 147.90±21.29 min, aortic clamping time was 115.70±15.23 min, mechanical ventilation time was 19.42±8.98 h, ICU stay was 99.08±49.42 h, and postoperative hospital stay was 16.33±2.74 d. Thoracic drainage volume was 333.33±91.98 mL on the first postoperative day. Only 2 patients required blood transfusion (4.5 U and 2 U, respectively). During the follow-up of 6.17±3.69 months, there was no death, no aortic or valve-related complications. There was statistical difference in the LVEDD between preoperation and before discharge after surgery (P＜0.001), and between half a year after surgery and before discharge after surgery (P＜0.001). There was a little decrease of LVEF before discharge after surgery compared with preoperative LVEF, but there was no statistical difference (P=0.219). There was no statistical difference in the LVEF half a year after operation compared with that before operation (P=1.000). Conclusion Sleeve wrapping technique using remnant aortic wall in modified Bentall procedure has good short-term results. This modification may be a simple, effective way in controlling proximal bleeding.
