2018年1月1日 · Vacuum-assisted venous drainage (VAVD) is a well-known technique widely used in both adult and pediatric cardiac surgery. During the last 10 years VAVD has been mainly used to reduce hemodilution during cardiopulmonary bypass (CPB) as it allows for a “lower prime” circuit, and smaller venous cannula during minimally invasive cardiac surgery ...

In the literature, it has been shown that the VAVD technique reduces the amount of blood transfusion [7-11]. Less use of blood products in CPB contributes to reducing Intra- and postoperative complications. Likewise, VAVD is used in minimally invasive and pediatric cardiac surgery with the idea to reduce the amount of blood transfusion [12-15].

One assisted venous drainage technique, vacuum-assisted venous drainage (VAVD), the aid of a vacuum in the venous reservoir, is now widely used to augment venous drainage during cardiopulmonary bypass (CPB) procedures. VAVD permits the use of smaller venous cannulae, shorter circuit tubing, and lower priming and blood transfusion volumes, but ...

Systematic review of vacuum assisted drainage in cardiopulmonary bypass, demonstrating its advantages and disadvantages, by case reports and evidence about its effects on microcirculation. We conducted a systematic search on the period 1997-2012, in the databases PubMed, Medline, Lilacs and SciELO.

Vacuum-assisted venous drainage (VAVD) to enhance venous return during cardiopulmonary bypass (CPB) was described as early as 1958 but was not widely used until the late 1990s. VAVD was initially used to facilitate the use of smaller cannulas with ministernotomy but was increasingly used to allow re …

2019年10月1日 · VAVD is promising technology that is widely used to reduce circuit volume, but additional research is needed to determine which negative pressure settings and safety features will allow for the smallest possible cannula size to be …

In cardiac surgery, especially in minimally invasive cardiac surgery and low-weight patients, VAVD technology has been widely used because of its significant advantages of improving venous...

2013年1月1日 · Applying VAVD allows for reduced circuit size and prime volume. It also improves venous drainage and flow rates through the smaller cannulae used in neonates and in peripheral cannulation for minimally invasive cardiac surgery. VAVD is a useful adjunct to modern CPB systems and offers a number of potential benefits to CPB.

VAVD is a common technique used in many cardiac surgery centers worldwide [11-13]. Its use seeks to significantly improve venous drainage during CPB surgeries, especially when smaller inner diameter cannulas are used or with minimally invasive surgery [14,15]. Applying vacuum to a sealed venous reservoir improves venous drainage, but it also ...

The diffusion of minimally invasive cardiac surgery (MICS) during open-heart surgery has increased the use of assisted venous drainage support for cardiopulmonary bypass (CPB). Peripheral cannulation with small cannulae and vacuum-assisted venous drainage (VAVD) during MICS has been adopted in our i …
