Single pump mechanically aspirated venous drainage (SPMAVD) for cardiac reoperation

Augmented venous return for minimally invasive open heart surgery with selective caval cannulation

“…Under these circumstances, the preferred alternative is the femoral or iliac approach for venous and arterial cannulation. This technique has proven its ef®ciency for other procedures such as certain dif®cult reoperations [6,7], ascending aortic aneurysm or dissection, or cases where the extent of arteriosclerosis contra-indicates the possibility of a direct aortic cannulation because of the high risk of emboli dislodgement [8]. It is also a convenient access for extra-corporeal membrane oxygenation, severe accidental hypothermia rescue or support angioplasty.…”

“…Other intracardiac procedures were then performed through a mini thoracotomy such as a mitral valve procedure [4] and an atrial septal defect (ASD) closure [5]. Alternative cannulation sites can be chosen for patients having reoperations, ascending aortic aneurysm or dissections, and aneurysms of the descending thoracic aorta, patients requiring support angioplasty or extra-corporeal membrane oxygenation, or patients necessitating CPB for severe accidental hypothermia [6,7]. These European Journal of Cardio-thoracic Surgery 16 (1999) 312±316 sites include ilio-femoral artery and vein, or less frequent axilloaxillary usage [8].…”

Extracorporeal circuit design considerations for giant intracranial aneurysm repair

“…Should other patients require this specific ECC technique, a revised closed-system single centrifugal pump, which achieves mechanical venous aspiration with synchronous arterial blood return, may be utilized in our attempt to offer selected cardiac and neurosurgical patients a further reduction in morbidity and mortality. 12 …”

Cardiopulmonary bypass for less invasive procedures

“…Kinetic assisted venous drainage has also been implemented in a single pump form, where blood is Cardiopulmonary bypass for less invasive procedures 281 both aspirated and infused. 20 Servo-control and automation of the kinetic pump siphon should make KAVD operation safer. In a small series of patients on extracorporeal life support, the use of a servocontrolled kinetic pump prevented excessive negative pressure generation and resulted in better renal function.…”
