Cilioretinal Artery Branch Avulsion Secondary to Surgical Embolectomy: Management and Outcome.

We report the trans-operative approach and short-term outcome of a patient who suffered a traumatic avulsion of the cilioretinal artery branch during the surgical management of a cilioretinal arterial branch occlusion (CRABO) with intraocular embolectomy. A patient with acute CRABO underwent a pars plana vitrectomy with in situ embolectomy. The blocked artery was incised using 25 gauge vertical scissors, and embolus manipulation was done using microsurgical forceps. During embolus extraction, the occluded cilioretinal artery and its branch were inadvertently avulsed and torn with subsequent intense bleeding. Laser and endodiathermy were used for acute hemostasis. The maneuvers created an unintended retinochoroidal anastomosis. Visual field improvement was noted 3 months after the surgery. In the event of a complicated surgical embolectomy with the avulsion of the artery, the formation of a retinochoroidal anastomosis and reperfusion of the occluded may occur along with the improvement of visual fields in some cases.
