Orbital hemorrhage during dacryocystorhinostomy (DCR) is a very rare but potentially devastating complication of this procedure. It is probably due to trauma to the anterior ethmoidal artery, which has a variable course and may have branches close to or in the surgical site. Increasing resistance to retropulsion of the globe is an important sign of orbital hemorrhage. If the hemorrhage does not resolve spontaneously, direct decompression of the blood within the orbit is necessary. The authors review their experience with this complication of DCR.
泪囊鼻腔吻合术（DCR）期间发生眼眶出血是该手术一种非常罕见但可能具有毁灭性的并发症。这可能是由于筛前动脉受到创伤，该动脉走行多变，可能在手术部位附近或内部有分支。眼球后推阻力增加是眼眶出血的一个重要体征。如果出血不能自行缓解，则需要对眼眶内的血液进行直接减压。作者回顾了他们处理DCR这一并发症的经验。
