心脏死亡后捐献角膜用作穿透性角膜移植术供体的安全性研究

目的:探讨心脏死亡后捐献(donation after cardiac death,DCD)角膜供体行穿透性角膜移植的安全性。方法:按照时间先后顺序,采用DCD供体角膜行穿透性角膜移植术,术后3~4mo检测角膜植片内皮细胞密度及最佳矫正视力。结果:共统计14例26眼DCD角膜供体纳入本研究。供体年龄0.5~61(平均38.3±15.6)岁;死亡原因包括脑外伤9例,心肌梗塞2例,脑干出血2例,呼吸循环衰竭1例。14例DCD捐献者28眼,因2眼暴露性角膜炎用作科学研究,共26眼用于穿透性角膜移植。所有患者手术过程顺利,手术后3~4mo未发生排斥反应,角膜植片保持透明。手术后3~4mo角膜内皮细胞密...

Summary:目的:探讨心脏死亡后捐献(donation after cardiac death,DCD)角膜供体行穿透性角膜移植的安全性。方法:按照时间先后顺序,采用DCD供体角膜行穿透性角膜移植术,术后3~4mo检测角膜植片内皮细胞密度及最佳矫正视力。结果:共统计14例26眼DCD角膜供体纳入本研究。供体年龄0.5~61(平均38.3±15.6)岁;死亡原因包括脑外伤9例,心肌梗塞2例,脑干出血2例,呼吸循环衰竭1例。14例DCD捐献者28眼,因2眼暴露性角膜炎用作科学研究,共26眼用于穿透性角膜移植。所有患者手术过程顺利,手术后3~4mo未发生排斥反应,角膜植片保持透明。手术后3~4mo角膜内皮细胞密度794~4 347(平均2 305±827)个/mm2,其中低于1 000个/mm2者1例(3.8%),1 000~2 000个/mm2者9例(34.6%),大于2 000个/mm2者16例(61.5%)。26例角膜移植受者年龄20~80(平均40.7±17.1)岁。手术前最佳矫正视力为光感(+)~0.08(平均0.027±0.024);手术后3~4mo最佳矫正视力为0.2~0.8(平均0.52±0.182),两者比较差异有显著统计学意义(t=3.96,P〈0.01)。结论:DCD捐献角膜用作穿透性角膜移植供体具有较高的安全性。

To test the safety of using cardiac death donation ( DCD ) corneas for penetrating keratoplasty surgery graft.METHODS:ln chronological order, suing DCD corneas penetrating keratoplasty, corneal endothelial cell density and best corrected visual acuity ( BCVA) were tested 3~4mo after surgery.RESULTS:A total of 14 cases of DCD while 26 corneas were included in this study. Donors age ranged 0. 5 ~61 years, averagely 38. 3 ± 15. 6 years. Causes of death included that 9 cases of traumatic brain injury, 2 cases myocardial infarction, 2 cases brain stem hemorrhage, 1 case of respiratory and circulatory failure. All 26 patients underwent penetrating keratoplasty, no rejection occurred and all grafts were transparent 3 ~ 4mo after surgery. Three to four months after surgery, corneal endothelial cell density ranged 794 ~ 4 347/mm2 , averaged 2 305 ± 827/mm2 , within which was only one case was lower than 1000/m
