Simultaneous Circumferential Body Lift and Four-Flap Breast Reconstruction Using Deep Inferior Epigastric Perforator and Lumbar Artery Perforator Flaps.

SUMMARY: The ideal autologous breast reconstruction provides a long-lasting and aesthetically pleasing result. The deep inferior epigastric perforator (DIEP) flap remains the gold standard for breast reconstruction; however, in a subset of patients, this flap may not provide adequate soft tissue to achieve the patient's aesthetic goals. The lumbar artery perforator flap has emerged as a useful adjunct to the DIEP flap for four-flap breast reconstruction, and also provides the patient with circumferential body contouring. From April 1 to July 1, 2019, the authors performed two bilateral stacked DIEP and lumbar artery perforator flap breast reconstructions. The authors retrospectively reviewed patient charts for pertinent data. Patients were chosen for reconstruction based on their physical examination and computed tomographic angiography findings. The operative technique used was unchanged for both reconstructions. The average total length of surgery was 553 minutes. The average DIEP flap weight was 510 g and the average lumbar artery perforator flap weight was 680 g. The average ischemia time for each lumbar artery perforator flap was 62 minutes. Length of stay was 3 days for both patients. This article describes the authors' approach to total breast reconstruction with stacked lumbar artery perforator flaps and DIEP flaps while also effectively performing a circumferential lower body lift. Critical components for success include appropriate patient selection and using a team approach with appropriately experienced staff at all levels of care.

Risk of Pneumothorax With Internal Mammary Vessel Utilization in Autologous Breast Reconstruction.

BACKGROUND: Complications associated with autologous breast reconstruction are well reported in the literature. Regardless of the type of free flap harvested, the anastomosis is most commonly performed to the recipient internal mammary vessels. Although pneumothorax is a known possible complication of breast surgery, incidence of pneumothorax in breast reconstruction involving the use of the internal mammary vessels is rarely discussed. The aim of our study was to determine the incidence of pneumothorax in deep inferior epigastric perforator (DIEP) flap breast reconstruction. METHODS: A single-institution review was performed examining the incidence of pneumothorax in cases of DIEP flap breast reconstruction with anastomosis to the internal mammary vessels over a 4-year period. Intraoperative irrigation was used to visually assess for evidence of pneumothorax during recipient vessel dissection and anastomosis. Anteroposterior chest radiographs were obtained on the first postoperative day to assess for pneumothorax. Additional variables analyzed included type of retractor used during recipient vessel dissection and history of radiation. RESULTS: A total of 180 patients underwent autologous DIEP breast reconstruction at our institution. The overall incidence of pneumothorax was 1.4 per 100 recipient vessel dissections and 2.2 per 100 patients undergoing breast reconstruction. There was a total of 4 cases of pneumothorax. Three were attributed to unknown causes, and 1 was due to direct injury to the parietal pleura via electrocautery. CONCLUSION: The use of the internal mammary artery and vein as recipient vessels continues to be the most common and reliable recipient for autologous breast reconstruction. Based on our data, pneumothorax does not seem to be a common complication of this procedure. If concern for iatrogenic injury to the pleura arises intraoperatively, we suggest the use of a saline bubble test to investigate the possible injury. Routine postoperative radiographs are not indicated unless the patient develops symptoms suggestive of pneumothorax.

Neoumbilicus after Selective Excision in Deep Inferior Epigastric Perforator Flap Breast Reconstruction.

The umbilicus offers no functional importance to the adult human but remains a key aesthetic landmark of the anterior abdominal wall, and its absence can be a cause for concern in aesthetic and reconstructive patients. Umbilical reconstruction or transposition for abdominoplasty and abdominally based flap operations is frequently complicated by umbilical death, infections, development of wounds needing prolonged wound care, and generally poor aesthetic outcomes. A multitude of techniques have been described to create the "ideal" neoumbilicus, but none has proven to be superior to the technique that comes before it. Our data demonstrate that, in a select set of patients, it may be beneficial to electively remove the umbilicus. Thus, umbilical reconstruction can be performed as an adjunct procedure to the primary operation with a superior aesthetic result and minimal risk for complications. This article describes the authors' approach to delayed neoumbilical reconstruction in patients undergoing elective umbilical resection.

Anatomical Dissection of the Dorsal Nerve of the Clitoris.

BACKGROUND: The clitoris is the primary somatosensory organ of female sexual response. Knowledge of its neural anatomy and related landmarks is essential for safe genital surgery. OBJECTIVES: The aim of this study was to describe the distal course of the dorsal nerves of the clitoris and associated structures. METHODS: Clitorises of 10 fresh cadavers were dissected. Measurements of the dorsal nerves, suspensory ligament, clitoral body, clitoral hood, and clitoral glans were obtained. The course of the dorsal nerves was examined. RESULTS: The dorsal nerves of the clitoris were larger than expected, ranging from 2.0 to 3.2 mm in diameter, on average, along their course in the clitoral body. In 9 of 10 specimens, the dorsal nerves could be traced to within 6 mm of the glans. They traveled deep to a superficial clitoral fascia but superficial to the tunica albuginea, were variably located between 10 and 2 o'clock, and were separated by the deep suspensory ligament (DSL) of the clitoris. The mean length of the descending clitoral body, from the angle to the base of the glans, was 37.0 mm. The mean distance from the pubic rim to the DSL was 37.7 mm. CONCLUSIONS: The clitoral body is substantial in length, mostly lying superficially under the clitoral hood and mons pubis. The dorsal nerves of the clitoris are large and superficial, terminating at or near the base of the clitoral glans. Knowledge of this anatomy is critical prior to performing surgery near the clitoris.
