Abstract:
Retinal vein occlusion (RVO) refers to the occlusion of the central retinal vein or primary and secondary branches caused by multiple factors. Clinical treatments for it include intravitreal or systemic vasodilator application, local usage of steroids and NSAID (non-steroidal anti-inflammatory drugs), thrombolysis, hemodilution, retinal laser photocoagulation, vitrectomy with vascular sheath incision, chorioretinal venous anastomosis (CRVA), and so on. At present, most treatments are aimed at RVO complications, while chorioretinal vein anastomosis can fundamentally reflux retinal vein blood through the choroid by venous vascular remodeling. Reports on the treatment of retinal vein occlusion by chorioretinal anastomosis are numerous in various countries. As a treatment means, CRVA can drain the venous blood, skipping the thrombosis spot, thus partially relieving anatomical vascular occlusion to achieve a therapeutic purpose. In this study, CRVA is evaluated from the aspects of indications, implementation process, postoperative effect evaluation, complications, and combination with anti-VEGF treatment. Based on the development of laser technology and vitrectomy, we hope to further review this treatment and provide a new reference for the clinical treatment of RVO.
摘要:
视网膜静脉阻塞(RVO)是指由多种因素引起的视网膜中央静脉或主要分支和次要分支的阻塞。它的临床治疗包括玻璃体内或全身血管扩张剂的应用,局部使用类固醇和NSAID(非甾体类抗炎药),溶栓,血液稀释,视网膜激光光凝,带血管鞘切开的玻璃体切除术,脉络膜视网膜静脉吻合术(CRVA),等等。目前,大多数治疗都是针对RVO并发症,而脉络膜视网膜静脉吻合术可以通过静脉血管重塑从根本上回流视网膜静脉血液通过脉络膜。关于通过脉络膜视网膜吻合术治疗视网膜静脉阻塞的报道在各个国家很多。作为一种治疗手段,CRVA可以排出静脉血,跳过血栓形成点,从而部分解除解剖血管闭塞以达到治疗目的。在这项研究中,CRVA从适应症方面进行评估,实施过程,术后效果评价,并发症,并结合抗VEGF治疗。基于激光技术和玻璃体切割术的发展,我们希望进一步综述此治疗方法,为临床治疗RVO提供新的参考。
