Aneurysm I: Introduction

563
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

Arteries of the Upper Limbs

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Aneurysm III: Interprofessional Care

416
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

451
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...

Summary
This summary is machine-generated.

Catheter-associated radial artery pseudoaneurysms (PSA) can resolve spontaneously if small. Surgical repair is effective for larger PSA or those causing complications.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Radiology

Background:

  • Catheterization procedures, including arterial lines and cardiac interventions, carry risks.
  • Radial artery pseudoaneurysms (PSA) are a potential complication of these procedures.
  • Understanding the natural history and management of PSA is crucial for patient care.

Purpose of the Study:

  • To review the causes, clinical course, and management of patients with catheter-associated radial artery pseudoaneurysm (PSA).

Main Methods:

  • Retrospective review of patients diagnosed with radial artery PSA between 2010 and 2015.
  • Diagnosis confirmed by duplex ultrasound.
  • Analysis of PSA etiology, size, and treatment outcomes.

Main Results:

  • Eleven cases identified: 5 from arterial lines, 6 from cardiac procedures.
  • PSA size varied from <1 cm to 5 cm; spontaneous thrombosis occurred in 4 smaller PSAs (<3 cm) within a mean of 27 days.
  • Seven patients underwent surgery (stalk excision and artery repair), with effective outcomes. One emergent surgery for carpal tunnel syndrome.

Conclusions:

  • Spontaneous thrombosis is a possibility for smaller radial artery pseudoaneysms.
  • Surgical intervention for PSA is effective when indicated, with good outcomes.
