Summary of the most common morphological types of TAT. Type 1: TAT arises from the second part of the axillary artery. First, the lateral thoracic artery branches out, and then the deltoid artery. Type 2: TAT arises from the second part of the axillary artery. The lateral thoracic, pectoral, and deltoid arteries branch out sequentially. Type 3: TAT arises from the second part of the axillary artery. First, the pectoral artery branches out, and then, the deltoid artery branches off. Type 4: Any other variation. An asterisk (*) indicate Type 4—Other, which is not an individual type but a separate set for the other TAT morphological types that do not fit Types 1–3
