コロナで肺障害、生体移植　世界初、息子と夫から―京大病院

　京都大医学部付属病院（京都市）は８日、新型コロナウイルス感染で肺障害を負った関西在住の女性に対し、息子と夫の肺を一部移植する手術を行ったと発表した。女性は集中治療室に入っており、息子らの経過は良好。コロナ感染後の肺障害に伴う脳死肺移植は欧米などで例があるが、生体間では世界初だという。
　同病院によると、女性は昨年末にコロナ感染し、入院先で呼吸状態が悪化して体外式膜型人工肺（ＥＣＭＯ）を使用。その後、コロナによる肺炎の後遺症で両肺が硬く小さくなり、ほとんど機能しなくなった。
　女性はコロナ陰性となったが、ＥＣＭＯで命をつなぎ、肺移植以外での回復は難しい状態だった。家族からの臓器提供の申し出を受けた同病院は、７日に生体肺移植を実施。女性の両肺を全て摘出し、息子の右肺の一部を女性の右肺に、夫の左肺の一部を女性の左肺に移植した。
　女性は手術後、人工呼吸器を装着しているが、ＥＣＭＯは外している。順調なら２カ月で退院でき、３カ月で社会復帰が可能だという。（2021/04/08-12:34）

Kyoto University Hospital said Thursday it has performed the world's first living donor lung transplant into a patient with lung damage from the novel coronavirus.
   The COVID-19 patient, a woman from the Kansai western Japan region, is now in the intensive care unit, and her husband and son, who gave her parts of their lungs, are in stable conditions after the surgery, conducted on Wednesday, said the hospital in the city of Kyoto, part of Kansai.
   Surgeries to transplant lungs from brain-dead donors to patients suffering lung damage related to the COVID-19 disease have been carried out in China, Europe and the United States, according to the hospital.
   The woman became infected with the virus late last year. After her respiratory condition deteriorated while she was undergoing treatment at a different hospital in Kansai, the woman was placed on an extracorporeal membrane oxygenation, or ECMO, machine. Later, due to the aftereffects of novel coronavirus-induced pneumonia, both of her lungs became stiff and small, and almost nonfunctional.
   The woman tested negative for the virus later, but she was alive only because of ECMO, and her recovery was seen as difficult unless she had a lung transplant.
