Flaps Flashcards
Ponten flap Classification
1981
Fasciocutaneous flaps
A multiple vessels at base of flap (ponten)
B single axial vessel (lower limb)
C multiple perforating vessels from intermuscular septum (RFF)
D type C with bone
Mathes and Nahai muscle classification
Type 1 Single dominant pedicle (TFL)
Type 2 Dominant and minor pedicles (Gracilis)
Type 3 Two dominant pedicles(Glut max)
Type 4 Multiple segmental pedicles (Sartorius)
Type 5 Single dominant and multiple minor pedicles which can support muscle (LD)
1981
Delay concept
Surgical interruption of part of the flap’s blood supply at a preliminary stage with intention to improve survival of the flap.
Pearl 1981:
Open choke vessels
Increase axiality of blood flow in random pattern flaps
Sympathectomy at borders -> vasodilation
Improve tolerance to ischaemia
Reduced hyperadrenergic state and vasoconstriction
Deltopectoral flap
Fasciocutaneous type C
Cutaneous axial pattern, Bakamjian 1965
Perforators from internal thoracic artery (3rd/4th IC space)
Pectoralis minor flap
Terzis 1980s
Type III
Pedicle: Pectoral branch of thoracoacromial artery from subclavian
NS: medial and lateral pectoral nerves
Trapezius flap
McCraw 1977
Type II
Pedicle: TCA (transverse cervical artery) from thyrocervical trunk.
Ascending branch to lateral flap, desc branch to vertical flap.
Lat Dorsi
Tansini 1906
Type V
Pedicle: Dominant: thoracodorsal artery off subscapular (after circumflex scapular a)
Also branches to Serratus anterior
Minor: posterior intercostals, lumbar artery perforators (LAP)
8cm length, 3mm artery
Serratus anterior
Type IV (segmental)
Upper/middle: subscapular, posterior scapular, superior thoracic
Distal: thoracic branch of thoracodorsal artery (only distal 3 of 5 slips can be used)
Scapular flap
dos Santos 1980, Nassif 1982, Hamilton 1982, Gilbert 1982
Adipocutaneous, fasciocutaneous or osteocutaneous.
Pedicle: circumflex scapular a - horizontal scapular branch and longitudinal parascapular bracnch
6cm length, 2mm artery
Omentum flap
1826? Jobet and Lambel
Kiricuta 1950s
1972 Harry Buncke and Donald McLean for scalp defect
Right omental a via gastroepiploic a., 2-3mm. 4-5cm length.
Upper laparotomy - identify greater curvature of stomach to find right & left gastroepiploic arteries. Ligate left and middle omental vessels.
Groin flap
McGregor and Jackson 1972
Fasciocutaneous flap
A: Superficial circumflex iliac artery (from femoral) = 3cm below where femoral a meets inguinal ligament
N: IC branch T12 and lat femoral cut nerve
Skin paddle - just medial to femoral v, to superolateral to vertebral column (35-40cm), 10-12cm width
Parascapular flap
Nassif 1982
Fasciocutaneous
Pedicle: circumflex scapular a (see scapular flap)
Gluteal flap
Ger 1972
Type III muscle or musculocutaneous
Dominant: superior and inferior gluteal arteries
Rectus abdominis
Robins 1979
Type III
Dominant: DIE
Minor: superior epigastric
8-10cm pedicle, 4mm artery
Pennington 1980 - TRAM
Allen 1994 - DIEP
Pectoralis major flap
Ariyan 1979
Type V
Dominant: pectoral branch of thoracoacromial (from subclavian)
Minor: lat thoracic, superior thoracic, intercostal perforators, internal thoracic perforators
Posterior interosseous flap
Penteado 1986
FC flap B
Desc branch of common interosseous division of ulnar a (10% direct from ulnar a)
1/3 from line between lateral epicondyle and DRUJ (pronated)
Enters post compartment betw supinator and APL, runs in septum betw EDM and ECU, with 7-14 perforators, anastomoses with perforating branch of ant IO at wrist
Deltoid flap
Type I
Pedicle: cutaneous branch of posterior circumflex humeral artery (from 3rd part of axillary a)
Temporal flaps
- STF ( STA = terminal branch of ECA, bifurcates 2-4cm above zygomatic arch into frontal and parietal branches, and middle temporal a (deep branch) immed above zygomatic arch)
- DTF (superficial to temporalis, suppl by middle temporal a, branch of STA)
- temporalis muscle (suppl by deep temporal arteries (branches of maxillary), type 3)
