Evaluation of transient thrombocytopenia in the postoperative period of aortic valve replacement
Transient thrombocytopenia is common after surgery for aortic valve replacement (AVR), but rarely studied systematically. Severe thrombocytopenia (platelets <50000/mL) often requires replacement of platelets and other blood products and exposure to their risks. The aims of this study are to v...

| description | Transient thrombocytopenia is common after surgery for aortic valve replacement (AVR), but rarely studied systematically. Severe thrombocytopenia (platelets <50000/mL) often requires replacement of platelets and other blood products and exposure to their risks. The aims of this study are to verify the occurrence of complications in patients presenting with severe post op thrombocytopenia (SPOT) after AVR and differences between biological (BP) and mechanical prostheses (MP) in relation to post-op thrombocytopenia. Methods: Retrospective study with 110 patients undergoing AVR surgery with cardiopulmonary bypass, at Hospital de Clínicas, State University of Campinas (Unicamp) between 2011 and 2017. Patients with previous cardiac surgery or other associated cardiac procedures were excluded. Demographic, pre, intra and post-operative data were analyzed. Results: Age and surgical risk EuroSCORE were higher in those who received BP. The total platelets number in the post-op was lower in BP than MP. There was no difference in bleeding and transfusion volumes between patients with BP and MP. Considering all patients, those with SPOT presented lower hemoglobin rates and higher blood transfusion volume, but there was no difference in bleeding volumes. Conclusions: SPOT in AVR was more prevalent in patients who received BP. Patients with SPOT did not present more bleeding volumes but received higher blood transfusion than patients without SPOT. |
