What is Thoracodorsal artery perforator flap?
The thoracodorsal artery perforator or TAP flap is a fasciocutaneous flap based on a musculocutaneous perforator or perforators from the thoracodorsal vessel axis and/or its vertical branch derivative.
What are perforator flaps used for?
Perforator flap 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.
What is lumbar artery perforator flap?
The lumbar artery perforator (LAP) flap is a relatively new procedure that can be utilized to manage lumbosacral defects in addition to reconstructing distal body parts as well, such as breast reconstruction.
Where is the thoracodorsal artery?
The thoracodorsal artery is a terminal branch of the subscapular artery that originates in the axillary region. It runs inferomedially along the lateral border of the scapula, then courses posteriorly passing deep to the latissimus dorsi muscle.
What is artery perforator?
A perforator flap is a flap consisting of skin and subcutaneous tissue that is perfused by an isolated artery and vein that perforates the deep tissues (muscle or fascia).
What is a perforator flap reconstruction?
Using flaps of a woman’s natural tissue for breast reconstruction can be done without transferring muscle tissue when the flap includes a perforating blood vessel. Perforator flaps promise optimal cosmetic results without the loss of muscle strength.
What does lap flap mean?
The lumbar artery perforator (LAP) flap provides excess skin and subcutaneous fat tissue from the lower back to upper buttock, known as ‘love handles’, without removing any donor muscle.
Where are the lumbar arteries?
The lumbar arteries are the four pairs of branches of the abdominal aorta found on the posterior abdominal wall. These arteries arise in series with the posterior intercostal arteries and complete the abdominal portion of the vascular supply of the posterior trunk wall.
What is gluteal flap?
An SGAP flap (superior gluteal artery perforator), or gluteal perforator hip flap, uses this blood vessel, as well as a section of skin and fat from your upper buttocks/hip (the so-called “love handles”) to reconstruct the breast. Because no muscle is used, an SGAP flap is considered a muscle-sparing type of flap.

|---|---|
| Branches | Lateral and medial branches, cutaneous branches |
| Supply | Latissimus dorsi muscle, serratus anterior muscle, subscapularis muscle, teres major muscle, axillary skin |
What are the types of perforators?
According to this, flaps are classified under three types: “(1) indirect muscle perforators or myocutaneous perforators that traverse through muscle and perforate the outer layer of deep fascia to supply overlying skin, (2) indirect septal perforators or septocutaneous perforators that traverse septum and supply …
What is the meaning of perforator?
perforator (plural perforators) A tool or machine that makes holes, or perforates, materials such as paper and card. A machine that can bore a tunnel underground.
What is flap in medical term?
A flap is a unit of tissue that is transferred from one site (donor site) to another (recipient site) while maintaining its own blood supply. Flaps come in many different shapes and forms. They range from simple advancements of skin to composites of many different types of tissue.
What does the lumbar artery supply?
The lumbar arteries join the lower posterior intercostal, subcostal, iliolumbar, deep circumflex iliac, and inferior epigastric arteries to form an anastomosis that supplies the back muscles, vertebrae and their joints, and the skin of the back.
What artery feeds the spinal cord?
vertebral arteries
The main blood supply to the spinal cord is via the single anterior spinal artery (ASA) and the two posterior spinal arteries (PSA). The anterior spinal artery is formed by the vertebral arteries which originate from the first part of the subclavian artery.
What is SGAP?
SGAP (superior gluteal artery perforator) flap procedure uses fat and skin from your upper buttock to create a new breast mound after a mastectomy. This flap procedure is fairly rare and is for patients who don’t have other options. You won’t need to have any gluteal muscle cut or moved for a SGAP reconstruction.
