PATIENT CONSENT STATEMENT We have obtained verbal consent from the patient or patient's parent/guardian. This study showed that SCD patients of S I i SP 0 sp genotype or with an associated -thalassaemia trait were more likely to be splenectomized than SS patients. VTEs included deep vein thrombosis (DVT) and pulmonary embolism (PE) while central venous catheter (CVC)-related thromboses were excluded. [Extracted from the article]
