The terms free flap, free autologous tissue transfer and microvascular free tissue transfer are synonymous terms used to describe the "transplantation" of tissue from one site of the body to another, in order to reconstruct an existing defect. "Free" implies that the tissue is completely detached from its blood supply at the original location ("donor site") and then transferred to another location ("recipient site") and the circulation in the tissue re-established by anastomosis of artery(s) and vein(s). This is in contrast to a "pedicled" flap in which the tissue is left partly attached to the donor site ("pedicle") and simply transposed to a new location; keeping the "pedicle" intact as a conduit to supply the tissue with blood.

  • Il lembo, in medicina, è un segmento di tessuto che contiene una rete di vasi sanguigni, e che può essere trasferito da un sito donatore per ricostruire un'area sede di perdita di sostanza (defect), causata ad esempio da traumi o da rimozione di tumori, oppure elevato temporaneamente dalla sua sede allo scopo di esporre le strutture sottostanti, per poi essere riposizionato nella stessa sede a fine intervento. La base del lembo, che contiene il supporto vascolare, è detta peduncolo. (it)

  • السديلة الحرة (بالإنجليزية: free flap)‏ أو نقل الأنسجة الحرة ذاتية المنشأ (بالإنجليزية: free autologous tissue transfer)‏ أو نقل الأنسجة الحرة ذات الأوعية الدقيقة (بالإنجليزية: microvascular free tissue transfer)‏ هي مصطلحات مترادفة تستخدم للإشارة إلى «زرع» نسيج من موضع ما إلى موضع آخر في الجسم، بهدف استبناء عيب ما. توصف هذه السدائل بالحرة إشارة إلى أنها تُفصل كلية عن إمدادها الدموي في موضعها الأصلي (الموضع المانح) ثم تُنقل إلى موضع آخر (الموضع المتلقي)، ويعاد إنشاء الدورة الدموية في النسيج عن طريق مفاغرة الأوعية الدموية. وهو ما يختلف عن (بالإنجليزية: pedicled flap)‏، التي يُترك فيها النسيج متصلًا بشكل جزئي بالموضع المانح عن طريق عنيقة (pedicle) ثم يُنقل إلى موضعه الجديد مع الإبقاء على العنيقة كمجرى لإمداد النسيج بالدم. يمكن نقل العديد من أنواع الأنسجة كسدائل حرة، كالجلد والدهن والعضلات والأعصاب والعظام والغضاريف، (كل على حدة أو بعضها مع البعض) والغدد اللمفاوية وأجزاء من الأمعاء. ومن أمثلة السدائل الحرة النقل الحر لإصبع القدم (بالإنجليزية: free toe transfer)‏، وفيه يُنقل إبهام القدم أو إصبعها الثاني إلى اليد لاستبناء إبهام بديل. وفي جميع هذه الحالات، يُستنشأ الإمداد الدموي باستخدام تقنيات الجراحة المجهرية لتوصيل الشريان والوريد.

  • The terms free flap, free autologous tissue transfer and microvascular free tissue transfer are synonymous terms used to describe the "transplantation" of tissue from one site of the body to another, in order to reconstruct an existing defect. "Free" implies that the tissue is completely detached from its blood supply at the original location ("donor site") and then transferred to another location ("recipient site") and the circulation in the tissue re-established by anastomosis of artery(s) and vein(s). This is in contrast to a "pedicled" flap in which the tissue is left partly attached to the donor site ("pedicle") and simply transposed to a new location; keeping the "pedicle" intact as a conduit to supply the tissue with blood. Various types of tissue may be transferred as a "free flap" including skin and fat, muscle, nerve, bone, cartilage (or any combination of these), lymph nodes and intestinal segments. An example of "free flap" could be a "free toe transfer" in which the great toe or the second toe is transferred to the hand to reconstruct a thumb. For all "free flaps", the blood supply is reconstituted using microsurgical techniques to reconnect the artery (brings blood into the flap) and vein (allows blood to flow out of the flap). Free autologous tissue transfer is performed by many surgical specialties. (en)
