目的 观察肝癌肝内动静脉分流对术后肺转移的影响。方法 3 2例可切除肝癌术前经肝动脉插管注入 5mCi(185MBq) 99mTc MAA ,获得肝肺分流率 ,术后随访 3年观察肺转移情况。结果 肺转移病人的肝肺分流率明显高于无肺转移者。结论 肝内动静脉分流量大者术后肺转移的可能性大。
Objective To observe the effect of hepatic arteriovenous shunt on postoperative lung metastasis. Methods Thirty-two patients with resectable hepatocellular carcinoma were injected with 5mCi (185MBq) of 99mTc MAA by preoperative hepatic artery catheterization to obtain the hepatic and pulmonary shunt rates. The lung metastasis was followed up for 3 years. Results The rate of hepatic and pulmonary shunt in patients with lung metastasis was significantly higher than those without lung metastasis. Conclusions Liver arteriovenous shunts have a high possibility of postoperative lung metastasis.
