まとめ
インサイト肺動脈血栓 (ISPAT) と低流量静止装置 (LFSA) は急性肺栓塞 (PE) を真似することができる. パレンキマ性肺疾患と換気- 輸血不適合症の患者は,PEではなく,これらの疾患のリスクが高い.
科学分野:
- 肺血管画像と診断
- 心肺病薬
- 放射線科
背景:
- 肺栓塞 (PE) はしばしば深静脈血栓 (DVT) 移行に基づいて診断されます.
- インサイト肺動脈血栓 (ISPAT) と低流量静止装置 (LFSA) は PEを模倣し,診断上の課題を提示する.
- ISPAT/LFSAの発症におけるパレンキマ肺疾患の役割は完全に理解されていません.
研究 の 目的:
- パレンキマ肺疾患をISPATの危険因子として定義する.
- 急性PEを模倣するISPAT/LFSAに関連する臨床的特徴を特定する.
- 肺疾患の患者におけるISPAT/LFSAと急性PEを区別する.
主な方法:
- 肺栓塞応答チーム (PERT) の活性化を必要とする急性PEと最初に診断された症例の遡及的レビュー.
- 含有基準:DVTの欠如,既にある肺疾患,肺パレンキマ異常に限定された血栓.
- ISPAT/LFSAの診断を確認するための放射線検査;5つの代表的な症例の定性分析.
主要な成果:
- 当初急性PEと診断された5例は,ISPATまたはLFSAとして再分類されました.
- これらの症例は,慢性肺疾患,換気-輸血不一致,および肺の病気領域に位置する血栓を有する患者を含む.
- 再分類されたすべての症例で,健康な肺部領域におけるDVTと血栓の欠如が認められた.
結論:
- 呼吸と輸血の不一致を伴うパレンキマ肺疾患は,急性PEを模倣するISPAT/LFSAの重要な危険因子です.
- ISPAT/LFSAは,PEの疑い,パレンキマ性肺疾患,DVTの欠如,および肺の異常領域の局所性血栓を有する患者の場合を考慮する.
- ISPAT/LFSAの治療は,抗凝固薬を必要としない生理学的に有益な現象である可能性があるため,個別化する必要があります.

Pulmonary Embolism I: Introduction
45
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...

Mitral Stenosis I: Introduction
34
Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...

Mitral Stenosis II: Clinical features and Diagnostic Tests
37
Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan
166
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...
