Perforator Flap Techniques in Breast Reconstruction
Summary
Perforator flaps represent an advanced approach to autologous breast reconstruction, harnessing skin and subcutaneous tissue nourished by isolated vessels that perforate underlying muscle. The deep inferior epigastric perforator (DIEP) flap has emerged as the gold standard, preserving abdominal musculature and minimising donor‐site morbidity. Alternative donor sites such as the profunda artery perforator (PAP) flap extend reconstructive options for patients unsuited to abdominal harvest. Perforator flap surgery involves meticulous preoperative imaging to identify vessel calibre and course, refined microsurgical dissection to harvest a well‐vascularised segment, and precise anastomosis to recipient chest vessels. Intraoperative strategies to optimise perfusion include surgical delay protocols and thermographic assessment. Collectively, these innovations have enhanced aesthetic outcomes, reduced complication rates and broadened global access to muscle‐sparing reconstruction.

Perforator Flap Techniques in Breast Reconstruction publication trend
The graph below shows the total number of articles in perforator flap techniques in breast reconstruction across all publications each year (not limited to Nature Index journals).
Technical terms
Perforator flap: A tissue segment comprising skin and fat supplied by vessels that perforate muscle without harvesting the muscle itself.
Deep inferior epigastric perforator (DIEP) flap: A muscle‐sparing abdominal flap based on the deep inferior epigastric vessels, widely used in autologous breast reconstruction.
Profunda artery perforator (PAP) flap: A thigh‐based flap supplied by perforators from the profunda femoris artery, serving as an alternative donor site.
Infrared thermography: An imaging modality capturing heat emission to visualise blood flow and identify perforator hotspots.
Computed tomography angiography (CT angiography): A radiological technique using contrast and X‐ray tomography to map vascular anatomy.
Hand‐held Doppler ultrasound: A portable device emitting sound waves to detect blood flow in perforator vessels preoperatively.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
