The Efficacy of Hydrodilatation for the Prevention of Vasospasm following Microsurgical Anastomosis.

Background:  Vasospasm is a major problem following microsurgical reconstruction which can result in the partial or complete loss of the flap tissue. The aim of this study was to investigate the efficiency of hydrodilatation for the prevention of vasospasm.

Methods:  Thirty male Wistar rats were used for this experimental study.

Long-term BTX-A effects on bi-articular muscle: Higher passive force, limited length range of active force production and unchanged intermuscular interactions.

Botulinum toxin type-A (BTX-A) is commonly used for spasticity management aiming at reducing joint stiffness and increasing joint range of motion in CP patients. However, previous animal studies showed acutely increased passive forces and a narrowerlength range of active force exertion (l) for muscles exposed. BTX-A can spread affecting mechanics of several muscles in a compartment, but it was shown acutely to diminishepimuscular myofascial force transmission (EMFT).

Long-Term Effects With Potential Clinical Importance of Botulinum Toxin Type-A on Mechanics of Muscles Exposed.

Botulinum toxin type-A (BTX-A) is widely used for spasticity management and mechanically aims at reducing passive resistance at the joint and widening joint range of movement. However, recent experiments on acute BTX-A effects showed that the injected rat tibialis anterior (TA) muscle's passive forces increased, and the length range of active force exertion ( ) did not change. Additionally, BTX-A was shown to spread into non-injected muscles in the compartment and affect their mechanics.

A Comparative Clinical Study of Flap Thickness: Medial Sural Artery Perforator Flap Versus Anterolateral Thigh Flap.

Introduction: The purpose of this study is to measure flap thicknesses of anterolateral thigh (ALT) and medial sural artery perforator (MSAP) flaps in healthy subjects by Doppler ultrasonography and compare the results in relation to sex and body mass index (BMI).

Method: The perforators of ALT and MSAP flaps were marked on 30 healthy subjects. The thickness of skin and subcutaneous tissue was measured in millimeters at the site of the perforator using Doppler ultrasonography.

Assessment of Tissue Perfusion Following Conventional Liposuction of Perforator-Based Abdominal Flaps.

Background: The effect of liposuction on the perforators of the lower abdominal wall has been investigated in several studies. There are controversial results in the literature that have primarily demonstrated the number and patency of the perforators. The aim of this study was to determine the effect of liposuction on the perfusion of perforator-based abdominal flaps using a combined laser-Doppler spectrophotometer (O2C, Oxygen to See, LEA Medizintechnik).
