Core Viewpoint - The incidence of acute pulmonary embolism (PE) is rising, necessitating increased awareness and preventive measures among high-risk populations [2][4]. Group 1: Incidence and Risk Factors - The global incidence of pulmonary embolism ranges from 11.7 to 131.9 per 100,000, with China's hospitalization rate increasing from 1.2 per 100,000 in 2007 to 14.2 per 100,000 in 2021, exceeding 200,000 cases [2]. - High-risk groups include the elderly, especially those over 80, who have a significantly higher risk compared to those under 50 [3]. - Other high-risk populations include pregnant women, patients undergoing surgery, those with malignancies, cardiovascular diseases, chronic obstructive pulmonary disease, kidney syndrome, obesity, smokers, and individuals who remain sedentary during long flights [4]. Group 2: Symptoms and Diagnosis - Symptoms of acute pulmonary embolism lack specificity, making it prone to misdiagnosis; common symptoms include activity-related shortness of breath, chest pain, and syncope [5]. - The classic triad of symptoms (chest pain, hemoptysis, and dyspnea) occurs in less than 20% of cases, highlighting the need for vigilance in recognizing atypical presentations [5]. - Diagnosis involves a two-step process: initial screening using ECG and echocardiography, followed by confirmatory imaging such as CT pulmonary angiography [6]. Group 3: Treatment and Management - Treatment strategies are tailored based on the severity of the condition, with high-risk patients requiring aggressive intervention and lower-risk patients primarily receiving anticoagulation therapy [7]. - Anticoagulation is the cornerstone of treatment, while thrombolysis is reserved for high-risk patients experiencing cardiac arrest or obstructive shock [7]. - Patients must adhere to prescribed medication regimens and undergo regular monitoring to prevent complications, including chronic thromboembolic pulmonary hypertension [8]. Group 4: Prevention and Prognosis - Prevention strategies include avoiding prolonged immobility, engaging in regular movement during long travels, and using compression stockings for high-risk individuals [8]. - The overall prognosis for pulmonary embolism patients is improving, but timely treatment and adherence to management plans are crucial to prevent severe outcomes [8].

Core Viewpoint - Spinal vascular malformations are often misdiagnosed due to non-specific early symptoms, leading to severe consequences if not treated in time. Public awareness and early intervention are crucial for effective management of this condition [1][6]. Group 1: Causes of Spinal Vascular Malformations - The primary causes of spinal vascular malformations are genetic mutations and spinal injuries, with genetic mutations being the most significant factor. Some mutations are hereditary, while most are acquired, leading to abnormal blood vessel structures [3]. - Individuals with a family history of vascular malformations or those engaged in heavy physical labor are at higher risk. Chronic inflammation and spinal injuries also contribute to the development of these malformations, particularly in middle-aged individuals [3]. Group 2: Misdiagnosis Issues - The misdiagnosis rate for spinal vascular malformations is high due to two main reasons: the lack of specific symptoms and the need for specialized diagnostic tools. Early symptoms may resemble common conditions like lumbar disc herniation, leading to oversight by both patients and healthcare providers [4]. - Standard examinations often fail to detect these malformations, necessitating MRI scans for accurate diagnosis. Many patients do not seek these targeted tests until symptoms worsen [4]. Group 3: Treatment Approaches - The main treatment methods for spinal vascular malformations include interventional therapy, microsurgery, and a combination of both. The use of combined techniques can enhance treatment efficacy and reduce the risk of paralysis [5]. - For suitable patients, less invasive interventional treatments are prioritized, while more complex cases may require a sequential approach involving embolization followed by surgical removal [5]. Group 4: Importance of Early Detection - Early recognition and intervention are critical in managing spinal vascular malformations. Individuals experiencing unexplained limb numbness, weakness, or urinary issues should seek immediate evaluation, especially if symptoms persist or worsen [6]. - Healthcare professionals must improve their diagnostic capabilities to avoid misdiagnosis due to symptom similarities. Advances in treatment techniques and increased awareness can lead to better patient outcomes [6].
