Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

462
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Peripheral Artery Disease I: Introduction

408
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

387
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

科学分野:

  • アナトミー アナトミー
  • 胚学 胚学について
  • 血管生物学 血管生物学

背景:

  • 持続中枢動脈 (PMA) は胚の残骸である.
  • 中央神経 (MN) に近いため,神経圧縮症候群と手機能障害と関連しています.
  • 既存の文献では,PMAの有病率データが異なっていることが示されています.

研究 の 目的:

  • 持続的な中枢動脈 (PMA) の有病率を決定する.
  • 中枢神経 (MN) に関するPMAの方向性を分析する.
  • 発見を既存の文献と比較する.

主な方法:

  • 102人の人間の死体前腕の解剖.
  • PMAの有病率と方向性の特定と文書化.
  • PMA光の厚さの測定と,以前の研究との比較.

主要な成果:

  • PMAの罹患率は12.7%であった (13/102).
  • 共通する指向は,前部ピアシング (61.5%),横部ピアシング (30.8%),中部ピアシング (7.7%) でした.
  • 一方的なPMA (9/13) は,二国間 (4/13) よりも頻繁であり,平均直径は0.45 ± 0.15 mmでした.

結論:

  • 研究結果は,以前の研究と一致しており,特に前部ピアシングPMAの有病率に一致しています.
  • PMAの罹患率は,以前の研究で報告された範囲内にある.
  • PMAの有病率,位置,方向性を理解することは,手足トンネル圧縮と外科的結果を管理するために不可欠です.
