Use of Two Novel Dyes to Enhance Visualization of Cut Ends of the Vessel in Microvascular Anastomosis-An Experimental Study of 45 Rats.

Background: Good visualization is a prerequisite for performing microvascular anastomosis. The most commonly used dye, methylene blue, has several limitations: it is washed off quickly and stains all the vessel layers. The objective of our study is to use 2 new novel dyes for improving visualization.

The Use of Retraction Sutures in End-To-Side Microvascular Anastomosis-A Novel Technical Innovation in Experimental Rat Femoral Model with Successful Use in STA-MCA Bypass in Moyamoya Disease.

Background: A narrow working space, small diameters, and the tendency to collapse with clamps make cerebral microvascular anastomosis challenging. A retraction suture (RS) is a novel technique to keep the recipient vessel lumen open during the bypass.

Objective: To provide a step-by-step overview of RS for end-to-side (ES) microvascular anastomosis on rat femoral vessels and successful use for superficial temporal artery to middle cerebral artery (STA-MCA) bypass in Moyamoya disease patients.

Traumatic Intra-articular Intercondylar Dislocation of the Patella Reduced by the Closed Method with Open Quadriceps Repair in an Adolescent: A Rare Case Report.

Acute patellar dislocation is a common condition and is seen in situations that are associated with dance and sports. The intra-articular dislocation of the patella is a rare condition while lateral dislocation is most common. Two types of intra-articular dislocations are described in the literature, horizontal and vertical.
