ABSTRACT
Objective To evaluate the possibility of no-beparin open operation at low costal arch in live donor nephrectomy via retroperitoneal approach. Methods The effects of 134 cases no-beparin operation and 82 eases heparinized operation at low costal arch in live donor nephrectomy via retroperitoneal approach during 2003.5 to 2008.5 in our hospital were retrospective analyzed. Results The kidneys of the donors in two groups were successfully harvested. The operation time varied from 110 rain to 200 rnin, and warm isebemia time varied from lOs to 20s. Delayed graft function (DGF) was oceurred in one ease in each group. There was no signifieant difference in live donor nephreetomy between the two groups(P >0. 05), but the no-beparin group had less bleeding. Conclusion The no-beparin open operation at low eostal arch in live donor nephrectomy via retroperitoneal approach is technieal]y feasible and safe, and has less bleeding, and little influence on the allograft.
ABSTRACT
Objective To evaluate the utility of modified Z-stent in treatment for Budd-Chiarisyndrome (BCS). Methods A retrospective study was used in twelve BCS patients treated in twohospitals. The Doppler examination was carried out in all patients preoperatively, so as to confirm thenature of the lesion and chose correct type of endovascular modified Z-stent. Under DSA monitoring formembranotomy and dilation of the inferior vena cava(IVC), after that, insert the marked modified Z-stent to IVC correctly, and put the non-stent part to hepatic vein orifice. The cavography and hepaticvenography should confirm the position of the Z-stent. All of 12 patients with membranous obstructionof the IVC(MOVC) or segmental obstruction of the IVC (SOVC)were underwent modified Z-stentplacement. Results The IVC pressure (IVCP) before smd after membranotomy (dilation) were 27.33± 4.12cmH2O and 18.67 ± 5.07cmH2O (P＜0.01). Comparing with dilation and putting stent group,the IVCP decreased from 18.67 ± 5.07cmH2O to 11.42 ± 2.11 cmH2O ( P ＜ 0.01 ). The modffied Z-stent could avoid hepatic vein orifice getting compression and resist the retraction of IVC throughly infollowing-up period of 2.5 years. Conclusion s The endovascular treatment of BCS with modified Z-stent is more effective and safer to prevent thrombosis. Further study will be required to observe theirlong term effects.
