Acute type-A aortic dissection is a surgical emergency and has a high rate of short-term mortality. Aortic dissection is highly under-reported in Pakistan. With the technological developments in its management, arterial cannulation technique of direct true lumen cannulation has emerged with improved outcomes. We aimed to compare the mortality and morbidity outcomes between direct true lumen and conventional cannulation techniques for arterial access in patients with acute type-A aortic dissection under a single-centre retrospective review from 2007 to 2017. Mean age of the participants was 43.3±11.6 vs 45±12.4 years with males being dominant in both groups. Frequency of overall morbidity was high in conventional cannulation group (Group-B), though it did not attain statistical significance, (p>0.999). Mortality rate was also high in Group-B (10% vs 30%), (p=0.582). Direct true lumen cannulation is an equally reliable option for establishing cardiopulmonary bypass due to reduced mortality and morbidity and may be given preference when dissection is extending into femoral and innominate arteries.
