A case of the Guillain-Barré syndrome occurring after otherwise uneventful cardiac surgery using cardiopulmonary bypass is presented. Though the Guillain-Barré syndrome has been reported after surgical procedures, there are very few case reports after cardiopulmonary bypass surgery in the literature. The exact pathophysiological cause of the syndrome is still unknown. However, the most widely accepted hypothesis is that the syndrome is the result of an immune-mediated process. Cardiac surgery may be a trigger for immune-mediated response.

Neck cannulation is a valuable alternative to groin vessels in patients above 15 kg. Risk of limb ischemia with groin cannulation is significant, and must be considered when choosing the cannulation site for ECMO support.

Objectives: The term, 'varicose veins' is used commonly to describe the enlargement and tortuosity of lower extremity veins. However varicose veins can occur elsewhere. The traditional surgical treatment has been vein stripping to remove the affected veins. In this article we aimed to present common anatomical variations of saphenofemoral junction encountered during surgical procedures in young adult patient population. Materials and Methods: Between January 2011 and January 2013, saphenofemoral junction compositions were investigated in 156 young adult patients who underwent great saphenous vein stripping with the diagnosis of superficial venous insufficiency. Data regarding the mean age of the patients, venous side branches draining to the saphenofemoral junction, the number of bifid saphenous vein and the distance between saphenous vein bifurcation to the saphenofemoral junction were recorded. Results: The age of patients were 21.64 ± 0.91(min:21, max: 25) and the number of side branches draining to the saphenofemoral junction was 4.9 ± 1.6 (min:1, max:8). Branches draining directly to the common femoral vein at the level of junction were detected in 4 cases (2.56%). Bifid saphenous vein was observed in 9 cases (5.7%), and three of them were draining to the junction as a common trunk. Conclusions: It should be kept in mind that the success rate of the surgical procedure may be relevant to anatomical variation. To be familiar with the anatomical variations may decrease the recurrence rates of disease.
