Impact of Postoperative Norepinephrine Administration on Free Flap Flow.

The perioperative interplay between blood pressure, vasopressors, and macrocirculation is well established. However, in the context of free flap surgery, the potential impact of these factors on microvascular flow remains elusive. The aim was to evaluate the impact of norepinephrine administration on the microcirculation of free flaps.

What about the donor site morbidity - how invasive is the free latissimus dorsi flap?

Aims: The free latissimus dorsi muscle (LDM) flap represents a workhorse procedure in the field of trauma and plastic surgery. However, only a small number of studies have examined this large group of patients with regard to the morbidity of flap harvest. The aim of this prospective study was therefore to objectively investigate the morbidity of a free LDM flap.

Neo-Omphaloplasty within a Vertical Scar: The Double Trapezium Flap Technique.

Various techniques for neo-omphaloplasty (or umbilicoplasty/umbiliconeoplasty) have been established in recent decades. However, when the omphaloplasty must be integrated into a vertical scar, most of these techniques are unsuitable. We established a technique comprising two "cross-border" trapezium flaps that come together in a key-lock fashion to be applicable for umbilical reconstruction in vertical scars.

Reconstruction of Chronic Soft Tissue Mallet Fingers: Outcomes of Step-Plasty vs. Purse-String Suture.

After failed conservative therapy or in the absence of any intervention, a rupture of the digital subcutaneous extensor tendon at the distal interphalangeal (DIP) joint, known as mallet finger, may lead to a chronic extension deficit due to excessive scarring and tendon elongation. Various surgical techniques to restore the extension of the distal phalanx have been proposed, but an optimal approach has not yet been established. To tighten the extensor tendon, a purse-string suture can be applied.

Impact of Negative Pressure Wound Therapy on Perfusion Dynamics in Free Latissimus Dorsi Muscle Flaps.

Free muscle flaps can develop significant postoperative edema and wound exudation, thereby increasing interstitial pressure and potentially compromising microcirculation. While concerns exist regarding negative pressure wound therapy (NPWT) to compress free flaps and hinder monitoring, recent studies have indicated a reduction in edema and an increase in blood flow. To compare microcirculation in free latissimus dorsi muscle (LDM) flaps dressed with and without NPWT.
