Subdermal Plexus Density as It Relates to Obesity and Wound Complications in Patients Undergoing Reduction Mammaplasty.

Background: Reduction mammaplasty is one of the most common reconstructive procedures performed in plastic surgery. Multiple comorbidities play a role in postoperative wound healing complications; however, there are insufficient data on the subdermal plexus (SDP) as it relates to these comorbidities. The purpose of this study is to evaluate the relationship between body mass index (BMI) and SDP of the superficial breast tissues and examine the association between SDP and postoperative complications.

Microcirculatory Effects of Botulinum Toxin A in the Rat: Acute and Chronic Vasodilation.

Background: Botulinum toxin-A (BTX) has numerous cosmetic and therapeutic applications. Our previous studies have found that BTX augments pedicled flap survival through both vasodilatory effects and attenuation of the inflammatory response to ischemia in the rat. This study examines the effect of chronic BTX on microcirculatory vascular tone and its response to acute topical vasodilators in muscle flaps.

The Effect of Activated Protein C on Attenuation of Ischemia-Reperfusion Injury in a Rat Muscle Flap Model.

Ischemia-reperfusion injury is often the final and irreversible factor causing flap failure in microsurgery. The salvage of a microsurgical flap with an ischemia-reperfusion injury contributes to the success of microsurgical flap transfers. Activated protein C (APC), a serine protease with anticoagulant and anti-inflammatory activities, has been shown to improve ischemic flap survival.

Intrathoracic migration of a breast implant after minimally invasive cardiac surgery.

The aging population, in combination with the popularity of breast augmentation with implants, presents surgeons with a growing number of cases involving women undergoing minimally invasive cardiac surgery (MICS) who have breast implants. We present an unusual complication involving the delayed migration of a subpectoral implant into the chest cavity through an iatrogenic defect after a minimally invasive mitral valve repair. This chest wall defect was ultimately repaired with a latissimus dorsi flap.
