Fat Graft Survival
別名: fat graft retention, volume retention, graft take, 지방 생착률, 생착률
Fat graft survival (retention) is the share of transferred fat volume that remains after healing; part of every fat graft is resorbed, and reported retention varies widely by technique, site and how it is measured.
이식한 지방은 왜 괴사하나요? 허혈과 생착은 어떤 관계인가요?
이식한 지방은 자기 혈관이 없는 상태로 옮겨지므로, 새 혈관이 연결되기 전까지는 주변 조직에서 오는 산소에 의존합니다. 한곳에 큰 덩어리로 주입되면 중심부까지 산소가 닿지 않아 중심이 괴사하고 섬유화·낭종·석회화로 이어질 수 있습니다. 그래서 소량씩 여러 층에 나누어 넣어 산소 공급과 혈관 재연결을 돕는 것이 생착의 핵심이며, 메타분석에서 지방괴사는 약 0.7%로 보고됐습니다.

概要
After fat is transferred, only a fraction survives long-term; the remainder is resorbed over months. Retention is influenced by harvesting and processing technique, graft volume per pass, recipient-site blood supply, donor site, patient factors and measurement method (3D imaging, MRI or estimation). Because methods differ, retention percentages from different studies are not directly comparable, and provider-reported figures should be read together with the study design behind them.
