Vascular persistence following precision micropuncture.

Objective: The success of engineered tissues continues to be limited by time to vascularization and perfusion. Recently, we described a simple microsurgical approach, termed micropuncture (MP), which could be used to rapidly vascularize an adjacently placed scaffold from the recipient macrovasculature. Here we studied the long-term persistence of the MP-induced microvasculature.

Reawakening Neuritis of the Median Nerve after Carpal Tunnel Release: Defining and Predicting Patients at Risk.

Background: Patients with long-standing carpal tunnel symptoms may develop transient and, paradoxically, worsened neuropathic pain immediately following release. The authors have termed this "reawakening phenomenon." The purpose of this study was to compare the characteristics of patients with this phenomenon to those with a standard postoperative course.

Induction of scaffold angiogenesis by recipient vasculature precision micropuncture.

The success of engineered tissues continues to be limited by time to vascularization and perfusion. Here, we studied the effects of precision injury to a recipient macrovasculature in promoting neovessel formation in an adjacently placed scaffold. Segmental 60 μm diameter micropunctures (MP) were created in the recipient rat femoral artery and vein followed by coverage with a simple collagen scaffold.
