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.Thrombosis of vein of Labbe is an uncommon finding and usually tends to occur along with extensive dural venous sinus thrombosis. Clinical presentation varies from headache to aphasia, dysarthria and upper motor neuron weakness symptoms. Recognized risk factors for thrombosis should be considered while diagnosis. MR venogram remains investigation of choice for detection and to look for the extent of thrombosis.Dural closure at the end of cranial surgery is considered an extremely important step to maintain anatomical continuity, separate the intradural space with the extradural one, and to prevent possible complications related to cerebrospinal fluid leak. Wherein its usefulness in posterior fossa craniotomy is es
