3:09 PM Abstract No. 362 Percutaneous transhepatic catheter-directed thrombolysis for the treatment of acute portal and mesenteric vein thrombosis

Abstract

The pressure measurement was performed 10 times for each condition. Repeated measures ANOVA was conducted for statistical evaluation. Results: With the presence of PCOM, pressures (mean/ median ± SD) during suction using 8-F with and without balloonocclusion of ICA are 23.6/23.5 ± 2.72 mm Hg and 32.3/32 ± 2.21 mm Hg. 9-F catheter achieved statistically superior aspiration both with and without BO (-43.6/-50 ± 10.3 mm Hg and-13.2/-9 ± 15.9 mm Hg) to those of 8-F catheter (P<0.000001). Aspiration with BO at ICA was more efficient than without (P<<0.000001). There was significant interaction between the catheter size and effect of BO (P ¼ 0.000002). With the absent PCOM, suction using either 8-F or 9-F catheter with and without BO are more efficient than those with the presence of PCOM (8F with BO:-6.7/-5.5 ± 2.36 mm Hg, 8F without BO: 35.0/35.0 ± 1.63 mm Hg, 9F with BO:-49.3/-50 ± 1.50 mm Hg, and 9-F without BO:-33.3/-36 ± 14.2 mm Hg; 8F vs. 9F, P<<0.000001; with BO vs. without, P<<0.000001). Conclusions: Both larger catheter size and use of BO demonstrated statistically more efficient aspiration with 3D printing stroke model. Significant interaction between catheter size and BO was noted. Presence of PCOM significantly decreased the efficiency of aspiration.
