ABSTRACT: Goal: The purpose of this research is to analyze the clinical characteristics, diagnosis, treatment, and prognosis of critical care patients with phlegmasia cerulea dolens (PCD) caused by deep vein thrombosis. Our goal is to improve both awareness and early diagnosis and treatment of rare clinical diseases. Furthermore, we aim to examine advancements in the diagnosis and treatment of deep vein thrombosis. Method: The clinical information of patients with PCD received in 2022 was subject to retrospective analysis. The author conducted a search of 191 publications with a focus on PCD, from January 2010 to July 2022, from databases such as the China National Knowledge Infrastructure (CNKI), Wanfang Data, PubMed, etc. The results were used to summarize the examinations, diagnostic criteria, and treatment progress of PCD patients. Additionally, the author conducted another search using keywords such as “Venous thromboembolism” and “Anticoagulant drugs” to summarize research progress in anticoagulant drugs and the treatment of VTE. The search was limited to relevant. Outcome: Six months prior to admission, the patient, a 68-year-old female, developed sunken edema and cyanosis in both her lower extremities and was diagnosed with lower extremity deep vein thrombosis complicated by PCD, lower extremity ischemic necrosis, and septicemia. This diagnosis was made using a combination of CT and lower extremity vascular ultrasound-related examinations, as well as a significantly elevated D-dimer value. Despite active treatment and aggressive measures, such as anti-infection, organ function maintenance, anticoagulation, and improvement of microcirculatory disorders, the patient’s family declined corresponding surgical treatment and interventional surgery for the lower extremity due to objective factors, and the patient ultimately succumbed to her illness. The clinical characteristics of this patient were similar to those of the 14 cases of PCD reported by Xie Fei et al. in 2022. Conclusion: For patients with malignancy, it is crucial to start anticoagulation and physical prevention of DVT early on. Patients with DVT complicated by PCD have a variety of surgical options available to them, including surgical embolization or PMT (percutaneous mechanical thrombus ablation), CDT (catheter contact thrombolysis), and fascial ventriculotomy decompression [1]. Additionally, it may be necessary to place an inferior venous filter. Although the incidence of this disease is low accounting for approximately 5% of all patients with iliofemoral deep vein thrombosis [2], the prognosis is poor, as the mortality rate can reach up to 40% - 60% due to venous gangrene, with an overall mortality rate of 20% - 40% [3]. To increase the survival rate, it is important to diagnose and treat this disease as early as possible.
