BACKGROUND A mathematical model to help explain the hemodynamic characteristics of perforator flaps based on blood flow resistance systems within the flap will serve as a theoretical guide for the future study and clinical applications of these flaps. METHODS There are 3 major blood flow resistance network systems of a perforator flap. These were defined as the blood flow resistance of an ana...

BACKGROUND The groin flap, based on the superficial circumflex iliac artery, was the first successful free flap. However, its popularity was lost essentially due to variable arterial anatomy. Clinical applications of perforator flap based on superficial circumflex iliac artery suggest that a dominant perforator based on his deep branch is enough to supply a large groin flap. METHODS Fresh cad...

BACKGROUND In this study, a new fasciocutaneous perforator flap raised from inner medial surface of the distal medial arm has been described for soft tissue coverage. METHODS The blood supply of this flap comes directly from the distal brachial artery. Fourteen limbs of 7 formalinized cadavers were dissected to study the origin and the course of perforator vessel. RESULTS The average size o...

BACKGROUND Classical flaps for perinasal defect reconstruction, such as forehead or nasolabial flaps, have some disadvantages involving limitations of the arc of rotation and two stages of surgery. However, a perforator-based flap is more versatile and allows freedom in flap design. We introduced our experience with reconstruction using a facial artery perforator-based propeller flap on the per...

Perforator flap breast reconstruction has strong appeal for many women undergoing mastec‐ tomies, but the procedure requires adequate donor site tissue. The most common donor site for perforator flap breast reconstruction is the abdomen, such as the deep inferior epigastric perforator (DIEP) or superficial inferior epigastric artery (SIEA) flap, as most women have adequate donor site tissue, th...

N and classification of compound perforator flaps can be as complex and convoluted as the vascular anatomy of these multicomponent flaps. The article “The Complete Nomenclature for Combined Perforator Flaps”1 presents the author’s proposed classification and standardized nomenclature for combined perforator flaps. I believe that the author’s classification of compound perforator flaps as either...

Autologous breast reconstruction utilizing a perforator flap is an increasingly popular method for reducing donor site morbidity and implant-related complications. However, aberrant anatomy not readily visible on computed tomography angiography is a rare albeit real risk when undergoing perforator flap reconstruction. We present an operative case of a patient who successfully underwent a bilate...

BACKGROUND Selection of a vascular pedicle for autologous breast reconstruction is time consuming and depends on visual evaluation during the surgery. Preoperative imaging of donor site for mapping the perforator artery anatomy greatly improves the efficiency of perforator selection and significantly reduces the operative time. In this article, we present our experience with magnetic resonance ...

BACKGROUND Perforator flaps are well established, and their usefulness as freestyle island flaps is recognized. The whereabouts of vascular perforators and classification of perforator flaps in the face are a debated subject, despite several anatomical studies showing similar consistency. In our experience using freestyle facial perforator flaps, we have located areas where perforators are cons...

Therapy for large symptomatic keloids is often plagued with complicated reconstruction manner and recurrence. This article reports a rare treatment combination for a chest keloid with internal mammary artery perforator flap reconstruction and radiation therapy. We excised the keloid and covered the defect with an internal mammary artery perforator flap. Immediate electron-beam irradiation thera...
