Thrombocytopenia associated with chronic liver disease presents a difficult management issue. Most reports conclude that portocaval and distal splenorenal shunts do not improve platelet counts in this setting. The response of thrombocytopenia after transjugular intrahepatic portosystemic shunt placement has not been studied. All platelet counts of 21 patients undergoing intrahepatic shunt placement were determined retrospectively to accumulate values at one month prior to procedure, weekly for the first month after the procedure, and monthly thereafter to six months. Comparison of pre- and postshunt platelet means showed a significant increase in counts in patients with a postshunt portal pressure gradient < 12 mm Hg, with the increment evident by one week after the procedure. This response was not seen when preshunt thrombocytopenia was used as the lone variable. This study suggests that the transjugular intrahepatic portosystemic shunt may improve the thrombocytopenia associated with liver cirrhosis when these pressure gradients are attained.
与慢性肝病相关的血小板减少症是一个难以处理的问题。大多数报告得出结论,在这种情况下,门腔分流术和远端脾肾分流术并不能提高血小板计数。经颈静脉肝内门体分流术(TIPS)置入后血小板减少症的反应尚未得到研究。对21例行肝内分流术患者的所有血小板计数进行回顾性测定,以积累术前1个月、术后第1个月每周以及此后至6个月每月的数值。分流术前和术后血小板均值的比较显示,分流后门静脉压力梯度<12 mmHg的患者血小板计数显著增加,术后1周即可明显看出增加。当仅将术前血小板减少作为变量时,未观察到这种反应。这项研究表明,当达到这些压力梯度时,经颈静脉肝内门体分流术可能改善与肝硬化相关的血小板减少症。
