Abstract

In patients with chronic liver disease, hepatopulmonary syndrome, the right to left shunt without previous pulmonary and cardiac disease, can develope and cause respiratory distress. Tools to prove shunt are contrast echocardiography, pulmonary angiography, and $^{99m}Tc-MAA$ perfusion lung scan. Among them, $^{99m}Tc-MAA$ scan is a simple and safe method detecting the right to left shunt. At the same time, quantitation of shunt amount is possible by this method. We report a case of hepatopulmonary syndrome confirmed by $^{99m}Tc-MAA$ scan and contrast echocardiography with review of literlatures.

만성간질환 환자에서 호흡곤란을 초래하는 간폐 증후군 발생한다는 사실은 잘 알려져 있다. 단락을 입증하기 위해서는 대비증강심초음파, 폐혈관조영술, $^{99m}Tc-MAA$ 폐관류스캔 등을 이용할 수 있다. 이 중에서도 $^{99m}Tc-MAA$를 이용한 폐관류스캔은 매우 안전하고 간편하게 단락의 존재 여부를 확인할 수 있으며, 단락의 양을 계산할 수도 있다. 정량이 가능하므로 병의 경과를 추적하는 지표로서도 유용할 것이다. 저자들은 $^{99m}Tc-MAA$ 폐관류스캔으로 진단한 간폐증후군의 증례를 문헌고찰과 함께 보고하였다.
