The lumbar artery perforator flap is a valuable alternative in breast reconstruction whenever the deep inferior epigastric perforator flap is not feasible because of insufficient or unavailable abdomi...
This article deals with a clinical case of a tube in a tube TDAP phalloplasty in a 38 years old trans-man. While penis reconstruction surgery aroused an efflorescence of different operative techniques...
In vulvar cancer, the standard treatment is radical local excision, with immediate reconstruction. Reconstruction aims to restore anatomy and function of the external female genitalia, facilitating pr...
The purpose of this paper is to describe the principles of perforator flaps for vulvar reconstruction....
Basic concepts, indications and operative technique are discussed and detailed....
In vulvar reconstruction, the use of perforator flaps is a superior surgical technique when compared to the use of conventional flaps....
The traditional donor sites for autologous breast reconstruction include the abdomen, thigh, buttock, and posterior thorax. Herein, we describe the use of the reverse lateral intercostal perforator (L...
Fifteen patients (30 breasts) were included in this retrospective review. The procedure was performed for immediate reconstruction following a nipple sparing mastectomy utilizing an inframammary incis...
Flap survival was achieved in all patients. Three flaps (10%) had 1-2 cm of intraoperative distal tip ischemia, which was managed by excision prior to inset and closure. At the 12-month postoperative ...
The reverse LICAP flap is a safe, effective, and reliable option for breast reconstruction following mastectomy....
The traditional design for truncal perforator flaps is ipsilateral without midline decussation. The presumed rationale is to minimize the risk of distal flap necrosis. In this article, the authors pre...
This retrospective analysis included 43 patients (25 men and 18 women) who underwent reconstructive surgery from 1984 to 2021 using a contralateral flap design crossing the midline in the anterior tru...
Contralateral flaps used included the internal mammary perforator flap ( n = 28) superficial superior epigastric artery flap ( n = 8), superior epigastric perforator flap ( n = 2), and the second or n...
The anatomical variation design suggests that the trunk midline is not a barrier and that perforator flaps in these two regions may be raised on different longitudinal axes without compromising vitali...
Therapeutic, IV....
Autologous free flap breast reconstruction allows for natural-appearing breasts, while avoiding the risks associated with implants, including exposure, rupture, and capsular contracture. However, this...
This cadaveric study aimed to describe the anatomy of the profunda artery perforators (PAPs)....
In total, nine free cadavers with 18 upper thighs were dissected, 12 of which were from female cadavers, and 6 were from male cadavers. The average age of the cadavers was 84.7 ± 4.2 years. Dissection...
The average number of perforators that penetrate the adductor magnus muscle was 2.5. The average distance from the origin of the perforators to the gluteal sulcus was 71.72 ± 28.23 mm. The average num...
The results provide a detailed anatomic basis for the PAP flap. The perforators of a PAP flap may be included in a flap with a transverse design. Sacrificing the small obturator nerves during dissecti...
The brachial artery perforator propeller (BAPP) flap has the advantages of both local and perforator propeller flaps, and it remains relatively underused partly because of the anatomical variations of...
