To assess the feasibility and safety of a novel closure technique, namely the parallel closure technique (Par-CT), in which the sheath is placed parallel to the ProGlide system during veno-arterial extracorporeal membrane oxygenation (VA-ECMO) to enhance the efficiency of percutaneous vascular haemostasis.
The abdominal aortas of goats were punctured with a 17F sheath to simulate arterial cannula vascular access for VA-ECMO, and the Par-CT was used to achieve vascular haemostasis. In five goats, the abdominal aorta was punctured with a 17F sheath and then a 6 to 10F vascular sheath was introduced. This resulted in a smaller vascular rupture area and successful closure of the aortic rupture using the Par-CT.
If the sheath tube that was introduced was < 8 F, the puncture site could not be closed and would therefore have to be resutured and the Par-CT would have to be repeated. However, the puncture site could be sutured appropriately if the sheath tube that was introduced was ≥ 8F.
This study suggested that the Par-CT is both safe and effective for haemostasis after weaning from VA-ECMO.
评估一种新型闭合技术，即平行闭合技术（Par-CT）的可行性和安全性，该技术是在静脉-动脉体外膜肺氧合（VA-ECMO）期间将鞘管与ProGlide系统平行放置，以提高经皮血管止血效率。
用17F鞘管穿刺山羊腹主动脉，模拟VA-ECMO的动脉插管血管通路，采用Par-CT实现血管止血。在5只山羊中，先用17F鞘管穿刺腹主动脉，然后置入6至10F血管鞘管。这导致较小的血管破裂面积，并使用Par-CT成功闭合主动脉破裂处。
如果置入的鞘管<8F，则穿刺部位无法闭合，因此必须重新缝合，并重复Par-CT。然而，如果置入的鞘管≥8F，则穿刺部位可适当缝合。
本研究表明，Par-CT在VA-ECMO撤机后止血方面安全有效。
