Irrigation pressure and vessel injury during microsurgery: a qualitative study.

Irrigation solution is routinely used in microsurgery. While the anticoagulation solution may aid in anastomotic patency, the direct effect of pressure irrigation can have a detrimental effect on the vessel. An experimental study was performed to determine the effect of irrigation pressure on the vessel wall.

Evaluation of histologic changes after microdermabrasion in a porcine model.

Background: There is a paucity of scientific information on the histologic changes associated with the clinical response to microdermabrasion.

Objective: In this study we sought to evaluate those changes in the skin after microdermabrasion, using a porcine model.

Methods: Using the left flank of an 8-week-old pig, we tattooed 4 areas with "A," "B," "C," and "D.
