DSA analysis of hepatic arteriovenous fistula concurrent with hepatic cancer and its clinical significance

Table 1 The relationship between locations of hepatic arteriovenous fistula and the typing as well as neoplastic blood supply

Location	na	Typingb			Neoplastic blood supply
		Massive	Nodular	Diffuse	Sufficient	Moderate	Poor
Peripheral	95	67	18	10	79	9	7
Central	15	7	3	5	10	5	0
N = 110		74	21	15	89	14	7

^aPeripheral cases significantly outnumbered central ones (P < 0.05, χ² = 6.05).

^bMassive cases significantly outnumbered diffuse ones (P < 0.05, χ² = 6.09). There is no difference between massive ones and nodular ones, or nodular ones and diffuse ones (P > 0.05). Peripheral ones outnumbered central ones in blood supply (P < 0.05, χ² = 7.34). Sufficient blood supply cases significantly outnumbered cases of moderate blood supply (P < 0.05, χ² = 5.83). There is no difference between those with sufficient and poor supply, or with moderate and poor supply (P > 0.05).
