Abstract
Legend
A 55-year-old otherwise healthy man presented with sudden visual disturbance in the right eye. Best-corrected visual acuity (BCVA) was 20/40. Fundus examination revealed intraretinal hemorrhages and venous dilation in the superotemporal quadrant, consistent with a branch retinal vein occlusion (BRVO) (Figure, A).
Medical history revealed peripheral venous catheter placement 3 months earlier complicated by accidental cannula tip migration into a left pulmonary artery branch confirmed on computed tomography (Figure, B and C). The patient had been managed conservatively at that time without anticoagulation therapy.
While a direct causal relationship between the cannula migration and the development of BRVO cannot be definitively established, the otherwise healthy cardiovascular profile of the patient and the relatively short temporal interval between the two events raise suspicion of a possible association. This case highlights the potential for delayed and remote vascular complications following catheter tip migration and underscores the importance of longitudinal surveillance.
