Tracheal Chondrosarcoma Excised With Extracorporeal Circulation

Introduction: Tracheal chondrosarcoma (TCS) is a rare malignancy, with only 19 cases described in the literature to date. Case presentation: Herein, we presented the third-largest TCS with such an airway compromise that neither orotracheal intubation nor jet ventilation or even tracheostomy was possible. So, extracorporeal circulation was needed to excise the tumor in a one-stage procedure. Th...

The Effect of Pulsatile Versus Nonpulsatile Blood Flow on Viscoelasticity and Red Blood Cell Aggregation in Extracorporeal Circulation

BACKGROUND Extracorporeal circulation (ECC) can induce alterations in blood viscoelasticity and cause red blood cell (RBC) aggregation. In this study, the authors evaluated the effects of pump flow pulsatility on blood viscoelasticity and RBC aggregation. METHODS Mongrel dogs were randomly assigned to two groups: a nonpulsatile pump group (n=6) or a pulsatile pump group (n=6). After ECC was s...

Calculation of Pulsatile Flow Characteristics in the Mechanical Circulation Assist Device for Fontan Circulation

We have been developing a pulmonary circulatory assist device using shape memory alloy fibres for Fontan circulation. It consisted of several shape memory alloy fibres, which covered the ePTFE conduit circumferentially. We designed the sequential motion control system for pulsatile flow generation for sophisticated pulmonary hemodynamics. In order to achieve physiological pulsatile flow assista...
