Differences were displayed
in comparisons by the maximum intensity of the ICG-concentrations. The maximum slope to the second maximum was found to be predictive in selected vessel types, and specific changes of the flow curve were found to indicate compromised vascular flow. The FLOW 800 tool applied for ICG angiography has shown to be a quick and reliable method for assessing blood flow in vessels in this study. The dynamic assessment of SB203580 datasheet the ICG signal allows reliable identification of microanastomotic complications with the described parameters. © 2013 Wiley Periodicals, Inc.

“Introduction: A major drawback to microvascular free flap breast reconstruction is the length of operation—up to 9 hours or more for bilateral reconstruction. This takes a significant mental and physical toll on the surgical team, producing fatigue that may compromise surgical outcome. To facilitate the operation we have incorporated a period of cold ischemia of the flaps such that members of the surgical team can alternate a brief respite during the operation. Methods:
LDE225 in vivo We retrospectively reviewed our series of microvascular free flap breast reconstructions performed over a four-year period in which cold ischemia of the flaps were induced. Results: Seventy patients underwent free flap breast reconstruction with 104 flaps. Mean cold ischemia time for all flaps was 2 hours 36 min. Average rest time per surgeon per case was 35 min. Complications included two total flap losses (1.9%), one partial flap loss (1.0%), one anastomotic thrombosis (1.0%), two hematomas (1.9%), three fat necrosis (2.9%), and two delayed healing (1.9%). Statistical analysis revealed that the probability of complications is inversely related to cold ischemia time (P = 0.0163). Conclusion: Cold ischemia facilitates breast reconstruction by allowing the surgical team to alternate breaks during the operation. This helps reduce surgeon fatigue and is well tolerated by the flap. Thus, we believe that the use of cold ischemia is safe and advantageous in microvascular breast reconstruction. © 2010 Wiley-Liss,

“Partial necrosis of skin flaps remains a significant problem in plastic and reconstructive surgery. In this study we attempted to evaluate Bay 11-7085 the effect of bone marrow-derived mononuclear cells (BM-MNCs) transplantation on improvement of skin flap survival in a rat random pattern skin flap model. Thirty Wistar rats were divided into three groups with each consisting of 10 rats. BM-MNCs and the adipose-derived stem cells (ADSCs) were transplanted into the subcutaneous tissue in the area where the flap would be dissected. The flaps were then raised two days after cells transplantation. The animals receiving the preoperative Dulbecco’s Modified Eagle Medium (DMEM) treatment were used as the controls. On the 7th postoperative day, the survival areas of flaps were measured and tissues were collected for examinations.
