Objective: To compare polyvinyl alcohol particles (PVA) and the micro-algae sodium microspheres(KMG)of embolic material effect through the internal iliac artery embolization in dogs. To compared polyvinyl alcohol (PVA) particles and micro-algae sodium microspheres (KMG) embolization agent to stopping bleeding effects and physical activity in dogs interval surgery for preoperative embolization of sacral tumors, reducing blood loss and postoperative complications, the choice of the embolic agent and the operation time to provide the theoretical basis.Methods The control group (A group of 5 dogs), preoperative catheter only, do not inject any embolic agent: experimental group B (15) with a diameter of 560-710umPVA iliac artery embolization in dogs; experiment Group C (15) with a diameter of 560-710umKMG canine iliac artery embolization, BC 1,3,5 days were simulated sacral tumor surgery, calculated blood loss was observed during the interval between surgery complications dog Results :group A and group B group C by ANOVA analysis, the A group relative to the B, C average amount of bleeding between the two groups was statistically significant (P <0.05); group B and group C by independent samples t test, The average blood loss was obtained between the two groups was statistically significant (P <0.05), and two groups 1,3-day average blood loss was the first statistically significant (P <0.05), and the first 5 days the difference was not statistically significant ( P> 0.05); B group compared: the first 3 days, 5 days bleeding increased relative to the amount of day 1 were: 32 ml, 49ml, with time, increasing the amount of bleeding, by the F test between the two groups, the difference was not statistically significant (P> 0.05) Conclusion: Preoperative embolization can significantly reduce bleeding, and the embolic agent KMG relatively PVA, and able better to reduce blood loss and postoperative complications. At the same time within 5 days of surgery in the PVA group, increasing the amount of bleeding is not obvious, but the first 5 days significantly increased the amount of bleeding tendency; KMG 1-3 days in the surgery, less bleeding, less impact on the organization embolism. |
