Arterial components around the distal ICA on the affected side in patients with and without PHACE syndrome^{^a}

	PHACE (+) (n = 11)	PHACE (−) (n = 9)	P Value^{^b}
A1	Dysplasia = 8 (72.7%)	Dysplasia = 7 (77.8%)	1.000
M1	Dysplasia = 0 (0.0%)	Dysplasia = 2 (22.2%)	.189
OA	Ectopic = 1 (9.1%)	Ectopic = 4 (44.4%)	.127
AchoA	Dysplasia = 3 (27.3%)	Dysplasia = 2 (22.2%)	1.000
PcomA	Dysplasia = 7 (63.6%)	Dysplasia = 7 (77.8%)	.642
Midbrain	Dysplasia = 5 (45.5%)	Dysplasia = 4 (44.4%)	1.000

↵a PHACE includes cases of confirmed and possible PHACE syndrome; a small midbrain was not used as a criterion.
