Abstract:
:The aim of this study was to provide a theoretical basis, using biomechanical properties, for the clinical application of human umbilical vein (HUV) as material for vascular grafting. This was a nonrandomized, non-controlled in vitro study. The experiment was conducted in the Laboratory of Medical Biomechanics, Yunyang Medical College. HUVs of 50 normal fetuses were collected on spontaneous miscarriage or labor with the pregnant women's permission by the Department of Obstetrics and Gynecology, Taihe Hospital, Shiyan, Hubei Province. Gestational aged ranged 24-42 weeks, and parturients were 20-30 years old. The pressure-volume (P-V) relationship of HUV was measured on the biomechanical experiment stand for soft tissues, and then compliance was calculated. The P-V relationship of HUV corresponded to a parabolic curve. The compliance of HUV increased gradually with gestational age [24-27 weeks (2.22+/-0.34) x 10(-4) mL/(kPa * cm), 28-32 weeks (3.65+/-0.46) x 10(-4) mL/(kPa * cm), 33-36 weeks (4.22+/-0.55) x 10(-4) mL/(kPa * cm), 37 weeks (7.63+/-0.48) x 10(-4) mL/(kPa * cm), 38 weeks (8.32+/-0.76) x 10(-4) mL/(kPa * cm)]. However, after 39 weeks of gestation, compliance decreased gradually with gestational age [39 weeks 7.61+/-0.46) x 10(-4) mL/(kPa * cm), 40 weeks (7.53+/-0.72) x 10(-4) mL/(kPa * cm), 41 weeks (4.13+/-0.35) x 10(-4) mL/(kPa * cm), 42 weeks (2.25+/-0.62) x 10(-4) mL/(kPa * cm)]. The compliance of HUVs collected at 37-40 weeks of gestational age was similar. When the HUVs older than 42 weeks or under 28 weeks were compared, there was significant difference in their compliance (F=65.84-86.52, p<0.01). The results of the present study suggest that HUVs collected at 37-40 weeks of gestational age have good compliance, i.e., a good P-V relationship, and therefore may be a suitable material for vascular grafting. HUV is one of several graft materials that may be used when autogenous saphenous vein is absent or inadequate. HUV is very biocompatible and shows promise for use in orthopedic implants.
