Patients with RA who did not meet the PGA remission criteria despite good disease condition were in a poorer psychological state than those who satisfied the Boolean-based definition of clinical remission. Psychological support might be effective for improvement of PGA, resulting in the attainment of true remission.
It has been proven that the use of an inferior vena cava filter (IVCF) is effective in decreasing the incidence of pulmonary embolism (PE) in high-risk spinal surgery patients. A case of fatal PE after spinal surgery in a 78-year-old woman who had a history of pulmonary hypertension due to peripheral PE treated with a permanent IVCF and anticoagulant therapy for 3 years is reported. The patient had experienced an episode of recurrent PE during the withdrawal of anticoagulants, but she had uneventfully undergone two orthopedic surgeries with a preoperative unfractionated heparin infusion instead of oral warfarin. Three months after the second operation, she underwent posterior lumbar spinal fusion. The following morning, she suddenly complained of chest discomfort and dyspnea with SpO(2) 78 %. An electrocardiogram showed a right bundle branch block. Then, 30 min later, she suddenly lost consciousness, and her carotid pulse was not palpable. The patient died 2 h and 30 min after onset. Acute PE probably occurred because of a massive thrombus above the IVCF. This case suggests that the efficacy of long- term use of a permanent IVCF is limited in cases when anticoagulants must be withdrawn, such as for orthopedic surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
