RationaleIntracranial aneurysm (IA) is defined as a localized dilation of cerebral arteries. With the continuous development of modern medical technology, surgery is still one of the main treatment methods. Although there are various postoperative complications, abnormal coagulation function is rare, especially those caused by lupus antibodies after surgery. The patient not only experienced postoperative abnormalities in coagulation function, but also discovered the presence of lupus anticoagulants in their body. Is the patient suffering from coagulation dysfunction caused by lupus anticoagulants, how is lupus anticoagulant produced, and what's special about treatment. With these questions in mind, we reviewed the entire treatment process of the patient.Patient ConcernsA 69-year-old woman presented with "headache and dizziness with neck pain" and was eventually diagnosed with IA hemorrhage. The patient underwent craniotomy under general anesthesia, and provided targeted support and treatment. Postoperative symptoms such as coma and intermittent fever occurred, and coagulation indicators were generally normal. After symptomatic support treatment, such as anti-infection treatment, the patient's temperature was gradually controlled. However, the abnormal clotting index and the efficacy of symptomatic therapeutic support, such as supplementation with coagulation factors, were not good. After further examination, the lupus anticoagulant was found, which provided us with a new treatment idea.DiagnosesCoagulation disorders, postoperative IA, hypertension grade 3 (extremely high risk), coronary atherosclerotic atheropathy, and type 2 diabetes.InterventionsThe patient developed abnormal coagulation function after craniotomy, and symptomatic support treatment with coagulation factor supplementation and plasma infusion was ineffective. Finally, the lupus anticoagulant was found after a series of relevant examinations. After timely adjustment of the treatment plan, the patient's coagulation indices gradually improved.OutcomesIn this report, we present the case of a patient with abnormal coagulation function caused by the lupus anticoagulant after IA surgery.LessonsThe coagulation function of the patient was abnormal after craniocerebral operation. After coagulation factor supplementation, the coagulation index of the patient was still not well improved. After further examination, the lupus anticoagulant was found. The treatment plan was actively adjusted, and the patient's condition gradually improved. Early recognition can allow doctors to provide appropriate therapy to patients.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
