Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation01:21

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

343
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...

Assessing Blood pressure using a doppler ultrasound

2.3K
To obtain accurate blood pressure measurements in clinical settings, especially when traditional methods are insufficient, healthcare professionals utilize the Doppler ultrasound technique. This method uses high-frequency sound waves to detect blood flow within the arteries, which is crucial for patients with conditions that complicate circulatory system assessment.

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Peripheral Artery Disease III: Interprofessional Care

232
Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

452
Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Summary

Duplex ultrasound (DUS) has limited accuracy for below-the-knee (BTK) arteries in chronic limb-threatening ischemia (CLTI) patients. Angiography is recommended for high-risk groups to ensure accurate diagnosis and treatment planning.

Area of Science:

  • Vascular Surgery
  • Diagnostic Imaging
  • Medical Technology

Background:

  • Duplex ultrasound (DUS) is widely used for lower extremity arterial disease evaluation.
  • Its accuracy for below-the-knee (BTK) arteries in chronic limb-threatening ischemia (CLTI) patients is not well-established.

Purpose of the Study:

  • To assess the diagnostic accuracy of DUS for BTK arterial lesions in CLTI patients.
  • To compare DUS findings with angiography in femoropopliteal and BTK arteries.

Main Methods:

  • Retrospective analysis of 233 CLTI patients (Rutherford grades 4-6) from 2018-2022.
  • Comparison of DUS findings with angiography for femoropopliteal arteries (FPA) and BTK arteries.
  • Identification of clinical factors influencing DUS-angiography concordance.

Main Results:

  • Femoropopliteal artery concordance was 82.0%.
  • BTK artery concordance was significantly lower: anterior tibial (52.9%), posterior tibial (58.6%), and peroneal (59.9%).
  • Reduced concordance was linked to older age, lean BMI, dialysis-dependent renal failure, and FPA stenosis.

Conclusions:

  • DUS has limited reliability for screening BTK lesions in CLTI patients, especially the elderly and dialysis-dependent.
  • Angiography is crucial for confirming DUS findings in high-risk patients to prevent underestimation of disease.
  • Identifying predictors of reduced DUS accuracy aids in individualized diagnostic pathways for CLTI.
