Using Thoracodorsal Artery Perforator Flap with Intercostals Nerve in Reconstruction Surgery 使用帶神經的胸背動脈穿支皮瓣於重建手術 陳理維 林政達 劉文忠 徐圭璋 楊國強 何彥儀 高雄榮民總醫院 外科部 重建整形外科 Good morning, its of great honor to have the opportunity to give oral presentation with the topic of a dual role of the IKK/NF-kB pathway in this meeting. I got the grant from my hospital: Kaohsiung Veteran General Hospital and have been to Michael Karin’s lab in University in San Diego since June 2001. I have done some experiments there and have some results. Now, I am going to present those results.

Thoracodorsal Artery Perforator Flap Arrow: deep fascial layer; L: Latissimus dorsi muscle, Sc septocutaneous ; Mc: muscuocutaneous; I, Intercostal artery perforator; Sa: serratus anterior muscle; R:rib; A: axial artery ; T; thoracodorsal artery

Thoracodorsal Artery Perforator Flap Two types of skin perforators from the descending br. Muscutaneous perforators: pierce LD muscle. Septocutaneous perforators: not penetrate muscle, course laterally between LD and SA muscle.

Thoracodorsal Artery Perforator Flap with Vascularized Nerve Graft for Ulnar Nerve Reconstruction Trauma induced a soft tissue with superficial branch of ulnar nerve defect over left hand. Conjoint point

Sensate Free Flap Add the sensory component of the free flap for the restoration of sensation. It is useful in upper aerodigestive tract defects, phalloplasty, hand and foot reconstruction. Radial forearm flap: most commonly used sensate flap: high donor site morbidity. Lateral arm fasciocutaneous flap: Ideal sensate free flaps: definite sensory nerve distribution, acceptable donor site morbidity, versatile flap. Conjoint point

Sensate Thoracodorsal Artery Perforator Flap The lateral cutaneous br of intercostal n bifurcates into an ant and post ramus. The posterior ramus courses along LD muscle and innervate skin over the muscle. D, deep fascia; I, intercostal n; T, thoracodorsal artery; P, thoracodorsal artery perforator; L, LD muscle ; S, SA muscle; Lc, lateral cutaneous br of interocostal n; Ar and Pr, anterior and posterior rami

Using Doppler to locate thoracodrosal a perforator and intercostal a perforator Conjoint point Concomitant intercostal a perforator Conjoint type: 60% Separate type Conjoint type: a posterior ramus course above LD muscle and main trunk travel with TDAP and reach together. Separate type: br of a posterior ramus enter the skin at different location from TDAP.

Using Sensate TDAP Flap in Phalloplasty

Sensate Thoracodorsal Artery Perforator Flap No difference existed in flap size between groups. The test showed better tactile sensation at the center of the flap in the sensate group than in the nonsensated group at 6 and 12 mons (p < 0.01) postoperatively. The tactile sensation at the peripheries of the flap between two gr: no significant difference at 6 months but significantly better in the sensate group than in nonsensated group at 12 months (p = 0.046).

Conclusion The sensate thoracodorsal artery perforator is an option for soft tissue reconstruction and restoration of sensibility with minimal donor site morbidity. Conjoint point
