Reoperation for bleeding after cardiac surgery.

BACKGROUND: Postoperative cardio-surgical haemostatic management is centre-specific and experience-based, which leads to a variability in patient care. This study aimed to identify which postoperative haemostatic interventions may reduce the need for reoperation after cardiac surgery in adults. METHODS: A retrospective case-control study in a tertiary centre. Adult, elective, primary cardiac surgical patients were selected (n = 2098); cases (n = 42) were patients who underwent reoperation within 72 h after the initial surgery. Interventions administered to control surgical bleeding were compared for the need to re-operate using multiple logistic regression. RESULTS: Rate of cardiac surgical reoperation was 2% in the study population. Three variables were found to be associated with cardiac reoperation: preoperative administration of fresh frozen plasma (OR 5.45, CI 2.34-12.35), cumulative volume of chest tube drainage and cumulative count of packed red blood cells transfusion on ICU (OR 1.98, CI 1.56-2.51). CONCLUSION: No significant difference among specific types of postoperative haemostatic interventions was found between patients who needed reoperation and those who did not. Perioperative transfusion of fresh frozen plasma, postoperative transfusion of packed cells and cumulative volume of chest tube drainage were associated with reoperation after cardiac surgery. These variables could help predict the need for reoperation.

COMBINED CENTRAL RETINAL ARTERIAL AND VENOUS OCCLUSIONS DUE TO LEUKEMIC INFILTRATION.

PURPOSE: To report combined central arterial and venous occlusions secondary to bilateral leukemic interfascicular optic nerve infiltration in a 56-year-old man. This was the sole presentation of a relapse in T/myeloid mixed-phenotype acute leukemia after 5 months of remission. METHODS: Case report with clinical photography. RESULTS: A 56-year-old man reported to be in complete remission of T/myeloid mixed-phenotype acute leukemia presented with sudden painless loss of vision in his left eye. Fundoscopy showed unilateral severe optic disk swelling with characteristic findings of a central retinal vein occlusion, namely, intraretinal and preretinal hemorrhages and cotton-wool spots, as well as the features of a central retinal artery occlusion resulting in a pale, edematous retina and a characteristic cherry-red spot. Blood analysis, cerebrospinal fluid evaluation, and bone marrow analysis were performed in combination with medical imaging. No evidence of leukemic relapse was found. An optic nerve biopsy was indicated because of decompensation of the contralateral eye and ultimately confirmed leukemic infiltration. CONCLUSION: Regardless of no hematological and nonspecific imaging findings, optic nerve biopsy may be crucial for clinical decision-making in a patient with acute complete vision loss and a history of leukemia.
