Intraoperative blood perfusion factors in free anterolateral thigh flap repair for diabetic foot ulcers: A retrospective analysis

Table 2 Preoperative vascular status and metabolic control evaluation of the two groups of patients, n (%)

Parameters	Normal blood perfusion (n = 50)	Abnormal blood perfusion (n = 50)	t/χ2	P value
Ankle-brachial index			7.29	< 0.01
Poor	5 (10.00)	16 (32.00)
Good	45 (90.00)	34 (68.00)
MAP (mmHg)	89.10 ± 10.43	86.79 ± 11.28	1.06	0.29
Glycated hemoglobin HbA1c (%)	7.39 ± 1.62	8.44 ± 1.43	3.44	< 0.01
Blood glucose (mmol/L)	7.83 ± 2.17	8.45 ± 2.13	1.44	0.15

Ankle-brachial index < 0.3 was defined as poor, Ankle-brachial index ≥ 0.3 was defined as good. HbA1c: Glycated hemoglobin; MAP: Mean arterial pressure.
