Brachial arteries sympathetic innervation: A contribution to anatomical knowledge

Table 1 Brachial artery flow rate before and after median nerve stimulation in the entire group (mL/min)

	n	Median	Min	Max	P value
Median pre-stimulation flow rate (mL/min)	15	79, 80	32, 9	201, 1	0.001
Median afer-stimulation flow rate (mL/min)	15	44	10, 9	103

Table 2 Brachial artery diameters prior to and following median stimulation (cm)

	n	Median	Min	Max	P value
Median pre-stimulation diameter of the brachial artery (cm)	15	0.35	0.26	0.5	0.001
Median after-stimulation diameter of the brachial artery (cm)	15	0.31	0.16	0.45

Table 3 Flow rate (ml/min) prior to and following ulnar stimulation

	n	Median	Min	Max	P value
Ulnar pre-stimulation flow rate (mL/min)	15	56, 40	28, 10	214	0.001
Ulnar after-stimulation flow rate (mL/min)	15	30	15	78

Table 4 shows the diameter of the brachial artery (cm) before and after ulnar stimulation in the entire group

	n	Median	Min	Max	P value
Ulnar pre-stimulation diameter of the brachial artery (cm)	15	36	23	50	0.001
Ulnar after-stimulation diameter of the brachial artery (cm)	15	28	19	48

Table 5 Absolute change in the brachial artery flow rate following medial and ulnar stimulation (mL/min)

		Absolute change in flow rate with median stimulation (mL/min)	Absolute change in flow rate with ulnar stimulation (mL/min)

Male (n = 8)	Median	4130	6865
	Min	1990	1210
	Max	12450	17010
