Abstract Details

Purpose:

Orbital ischemia syndrome is a rare but very serious complication of spine surgery The resulting ischemia affects structures very sensitive to anoxia, in particular the retina Often results in permanent loss of vision

Setting:

We report a case of orbital ischemia after spinal surgery

Methods:

45-year-old patient, with no specific pathological history Operated for compression syndrome of the spinal cord secondary to a medullary tumor at the level of D1 Intervention: under A / G, prone, the face resting on a headrest with support on the base of the left orbit, duration = 4h D1 post-op: palpebral edema, chemosis, exophthalmos, BAV of the OG OG exam: AV to PL zero Mydriasis RPM: direct abolished, consensual present Palpebral edema, chemosis, discreet exophthalmos, total ophthalmoplegia (photos 1 and 2) FO: OACR OD exam: normal Treatment started: oral corticosteroid therapy in large doses for 2 weeks.

Results:

Examination on D21: AV to PL zero Regression of eyelid edema, chemosis, exophthalmos and ophthalmoplegia FO: optic atrophy with narrowed, filiform and sheathed retinal arteries (photo 3) Through this observation, we discuss the circumstances and the mechanisms of the appearance of this formidable complication.

Conclusions:

Orbital ischemia syndrome is a rare complication of spinal surgery with prone position Adequate protection of the eyeball as well as intraoperative monitoring make it possible to avoid this formidable complication.
