Blood Platelet Disorder

In severe lung or heart disease, ExtraCorporeal Membrane Oxygenation (ECMO) may be used temporarily and can be responsible for major haemorrhagic complications. Thrombocytopenia and possibly thrombopathy promote bleeding. The primary objective is to characterize platelet dysfunction by aggregometry tests over time. Secondarily, investigators seek a correlation between haemorrhagic complications at day 10 and markers of platelet action and dysfunction; also, with the level of anticoagulation and inflammation by biomarkers.

The main hypothesis of this study is that preoperative hemogram parameters can be used as biomarkers for malignancy in patients with thyroid nodule Bethesda 3 cytology. The secondary hypothesis is that BRAF molecular testing has a high predictive value in predicting malignancy in patients with thyroid nodule Bethesda 3 cytology. Primary outcome: Preoperative hemogram parameters. Secondary outcome: BRAF positivity.
