Evaluation of 2 Low-cost High-definition Video Systems for Venous Anastomosis.

. A literature review of the use of video systems for magnification has suggested that so far, this novel magnification system has only been used to perform arterial anastomoses. The aim of this study was to evaluate the use of 2 low-cost methods of video-assisted magnification in microvascular venous anastomosis in rats.

Continuous versus interrupted suture technique in microvascular anastomosis in rats.

Purpose: To compare the continuous and interrupted suture technique on femoral artery on rats after vessel repair and 14 days after.

Methods: Twenty rats were operated randomly divided into two group matched according to the suture technique used: interrupted or continuous. We performed a femoral anastomosis on the right femoral artery.

Morphometric analysis of rat femoral vessels under a video magnification system.

The right femoral vessels of 80 rats were identified and dissected. External lengths and diameters of femoral arteries and femoral veins were measured using either a microscope or a video magnification system. Findings were correlated to animals' weights.

A Low-Cost High-Definition Video System for Microsurgical Hindlimb Replantation in Rats.

 The surgical microscope is still essential for microsurgery, but several alternatives that show promising results are currently under development, such as endoscopes and laparoscopes with video systems; however, as yet, these have only been used for arterial anastomoses. The aim of this study was to evaluate the use of a low-cost video-assisted magnification system in replantation of the hindlimbs of rats.  Thirty Wistar rats were randomly divided into two matched groups according to the magnification system used: the microscope group, with hindlimb replantation performed under a microscope with an image magnification of 40× and the video group, with the procedures performed under a video system composed of a high-definition camcorder, macrolenses, a 42-in television, and a digital HDMI cable.

Is it possible to do a microvascular anastomosis with an ordinary video camera? Experimental study.

An alternative method of magnification for microvascular anastomosis was analyzed using an ordinary video camera and compared with the traditional method under microscope. For this study 20 rats were divided in two groups of 10 each: control group (microscope-assisted [M]) and experimental group (video-assisted [V]). Magnification was accomplished by a surgical microscope in group M, whereas a video system composed of low-cost camera, audiovisual cable, and analogue television in group V.
