<unk> surgery is a technique used in reconstructive surgery where skin and/or subcutaneous fat are removed from a distant or adjacent part of the body to reconstruct the excised part. The vessels that supply blood to the<unk> are isolated<unk> (s) derived from a deep vascular system through the underlying muscle or intermuscular septa. Some<unk> s can have a mixed septal and intramuscular course before reaching the skin. The name of the particular<unk> is retrieved from its<unk>  and not from the underlying muscle. If there is a potential to harvest multiple<unk>  from one vessel, the name of each<unk> is based on its anatomical region or muscle. For example, a<unk>  that only traverses through the septum to supply the underlying skin is called a septal<unk> . Whereas a<unk> that is vascularised by a<unk>  traversing only through muscle to supply the underlying skin is called a muscle<unk> . According to the distinct origin of their vascular supply,<unk> s can be classified into direct and indirect<unk> s. Direct<unk> s only pierce the deep fascia, they don't traverse any other structural tissue. Indirect<unk> s first run through other structures before piercing the deep fascia.
