Abstract
RATIONALE: In this study, we aimed to enhance the self-care abilities of a patient with severe ovarian hyperstimulation syndrome complicated by multiple thromboses in the muscular veins of the left lower extremity, guided by Orem's Self-Care Theory. PATIENT CONCERNS: When does ovarian hyperstimulation syndrome subside; whether venous thromboembolism be cured; whether there will be sequelae; when can frozen-thawed embryo transfer be done; when can one get pregnant. DIAGNOSES: Severe ovarian hyperstimulation syndrome complicated by multiple thromboses in the intermuscular vein of the left lower extremity. INTERVENTIONS: Using a supportive educational nursing system, the patient successfully performed self-assessment during the acute phase of venous thromboembolism and actively participated in adjusting and implementing the nursing intervention plan. Continuous monitoring of the patient's condition was ensured through follow-up, dynamic assessment, and ongoing adaptation of personalized support and education. Furthermore, a shared decision-making approach was used to formulate a management plan aimed at preventing the recurrence of thrombosis post-transplantation. OUTCOMES: Following effective treatment and nursing interventions, the patient achieved a successful pregnancy and delivery, with no recurrence of thrombosis. LESSONS: The application of Orem's Self-Care Theory in nursing practice for patients with severe ovarian hyperstimulation syndrome complicated by deep vein thrombosis can improve patient participation, satisfaction, and pregnancy outcomes, and reduce the occurrence of nursing errors and accidents.
