Table 2 Types of obstruction in the IVC and HV in 115 patients

	Membraneous	Segmental (extent, cm)
IVC Stenosis (n = 54)	30	24 (1-7.6)
Occlusion (n = 48)	19	29 (1-7.2)
HV Stenosis (n = 11)	6	5 (1-4.5)
Occlusion (n = 19)	11	8 (1-4.0)

IVC = IVC group + combined group, HV = HV group + combined group.
