[Alternative arterial cannulation site in acute aortic dissections].
BACKGROUND
Acute aortic dissection is an urgent surgical disease. Often, due to hemodynamic instability, that is an indication for emergent surgical intervention. Majority of surgeons uses Femoral or Axillary artery as arterial inflow site forextracorporal circulation. Both approaches have disadvantages that potentially may cause devastating complications. Some of them have been described in literature such as inadequate flow on heart-lung machine, retrograde dissection and malperfusion syndrome.


OBJECTIVE
Aim of study is to show, that by using transventricular cannulation we are eliminating all technical problems and lowering peroperative morbidity and mortality.


METHODS
Between 1996-2006 at Institute for Cardiovascular Disease "Dedinje" 107 patients were operated for acute ascending aortic dissection Femoral artery was used for arterial cannulation in 91 patients. Last 16 patients were operated by using transventricular approach to establish extracorporeal circulation. We used retrograde cerebral perfusion in 21 cases at the beginning of our experience.


RESULTS
In group of patients where transapical cannulation was used, no neurological incidents were noticed. We didn't have any other problems related to extracorporeal circulation or placement of arterial cannula. Is this series we had only one death case. Patient passed away on eight postoperative day due to multiorgan insufficiency.


CONCLUSIONS
Transapical cannulation is very simple and safe method for quick establishment of extracorporeal circulation. It always gives patient sufficient antegrade, physiological flow on heart-lung machine. This is the way to minimize possibility of malperfusion syndrome and to significantly diminish risk of neurological complication. By using this method all negative effects of other cannulation sites will be avoided.
