まとめ
肺栓塞 (PE) の疑いのある患者には,低または中程度の臨床確率とCTスキャンおよび超音波の陰性結果がある場合,抗凝固剤治療を中止することは安全です. この診断戦略は,フォローアップ中の患者の安全性を保証します.
科学分野:
- 医療診断 医療診断
- 心血管医学は,心臓血管医学である.
- 放射線学 放射線学
背景:
- 肺栓塞 (PE) の疑いに対する診断戦略を評価する将来的な多中心的アウトカム研究.
- 戦略は,臨床確率評価,スパイラルCT,静脈圧縮超音波を組み合わせたものです.
- 主な目的:陰性画像を持つ低/中程度の確率のPE患者で抗凝固剤を控える安全性を評価する.
研究 の 目的:
- 肺栓塞 (PE) の診断戦略の安全性と有効性を評価する.
- 特定の患者グループにおいて抗凝固剤治療を無事に中止できるかどうかを判断する.
- 不必要な抗凝固と関連するリスクを減らすために.
主な方法:
- PEの疑いのある1041人の入院患者および外科医が登録されました.
- 低/中等臨床確率と陰性スパイラルCT/超音波検査の患者は治療を受けませんでした.
- 高確率の患者は肺スキャニングおよび/または肺血管撮影を受けた;すべての患者は3ヶ月間追跡された.
主要な成果:
- 肺栓塞 (PE) は,患者の34.6%で診断され,55人は陰性CTにもかかわらず,陽性超音波検査を受けた.
- 陰性画像と低い/中間的な確率を持つ601人の患者のうち,507人が未治療でした.
- 未治療の9人の患者 (1.8%) は,フォローアップ中に静脈血栓塞栓症を経験しました.
結論:
- 抗凝固剤の治療を中止することは,PEの臨床的確率が低いまたは中等で,スパイラルCTと超音波検査の結果は陰性である患者にとって安全です.
- 診断戦略は,抗凝固剤を無事に放棄できる患者を効果的に特定します.
- このアプローチは,PEの診断の正確性を維持しながら,治療のリスクを最小限に抑えます.

Chronic Obstructive Pulmonary Disease-IV: Assessement and Diagnostic Studies
Assessing and diagnosing Chronic Obstructive Pulmonary Disease (COPD) involves a detailed approach that includes a comprehensive review of medical history, physical examination, and a variety of diagnostic tests. This thorough evaluation is essential to ensure an accurate diagnosis and guide effective management strategies.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Acute Coronary Syndrome III: Diagnostic Studies
Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
Pulmonary Embolism I: Introduction
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...
Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
