Improvement in Cerebral and Ocular Hemodynamics Early after Carotid Endarterectomy in Patients of Severe Carotid Artery Stenosis with or without Contralateral Carotid Occlusion

Table 5

Ocular BFV ipsilateral and contralateral to ICA stenosis in patients with severe CS and contralateral CO after and before CEA.

	OA with retrograde flow (%)	CRA (cm/s)	SPCA (cm/s)
Ipsilateral to ICA stenosis
Pre-CEA	1/5 (20%)	7.51 ± 2.02	7.35 ± 1.36
Post-CEA	0/5 (0%)	8.85 ± 2.25	12.4 ± 4.31
value	NA	0.38402	0.03723
Contralateral to ICA stenosis
Pre-CEA	1/5 (20%)	6.67 ± 3.06	6.11 ± 1.29
Post-CEA	0/5 (0%)	7.66 ± 3.01	7.56 ± 1.97
value	NA	0.08432	0.12419

BFV, blood flow velocity; ICA, internal carotid artery; CS, carotid stenosis; CO, carotid occlusion; CEA, carotid endarterectomy; CRA, central retinal artery; SPCA, short posterior ciliary arteries; OA, ophthalmic artery; NA, not applicable.
