The number of ABO-incompatible solid organ transplantations (ABOi SOTs) has markedly increased worldwide since the early 2000s. We investigated the choice of ABO group for blood component transfusion in ABOi SOT. We conducted a survey by e-mailing a questionnaire to blood bank specialists at 77 major hospitals in Korea, among whom 34 responded to the survey. In major ABOi SOT, for red blood cells (RBCs), the recipient's type (70.6%) was the most common choice, followed by group O (29.4%); for platelets, group AB (50.0%) was the most common choice, followed by the donor type (38.2%); for plasma, group AB (55.9%) was the most common choice, followed by the donor type (32.4%). In bidirectional ABOi SOT, for RBCs, the recipient's type (55.9%) was the most common choice, followed by group O (44.1%); for platelets and plasma, group AB was the most common choice (94.1% and 97.1%, respectively). The policies for transfusion in ABOi SOT were diverse. We suggest a guideline on the choice of ABO group for transfusion in ABOi SOT to secure patient health and enable an efficient use of blood components.

ABO血型不合实体器官移植中血液成分输血的ABO组选择：韩国问卷调查和指南建议。

自 2000 年代初以来，ABO 不相容实体器官移植 (ABOi SOT) 的数量在全球范围内显着增加。我们研究了 ABOi SOT 中血液成分输注的 ABO 组选择。我们通过电子邮件向韩国 77 家主要医院的血库专家发送问卷调查，其中 34 人回复了调查。在主要ABOi SOT中，对于红细胞（RBCs），受者类型（70.6%）是最常见的选择，其次是O组（29.4%）；对于血小板，AB组（50.0%）是最常见的选择，其次是供体类型（38.2%）；对于血浆，AB 组 (55.9%) 是最常见的选择，其次是供体类型 (32.4%)。在双向 ABOi SOT 中，对于 RBC，受者类型（55.9%）是最常见的选择，其次是 O 组（44.1%）；对于血小板和血浆，AB 组是最常见的选择（分别为 94.1% 和 97.1%）。ABOi SOT 的输血政策多种多样。我们建议在 ABOi SOT 中选择 ABO 组进行输血，以确保患者健康并有效利用血液成分。
