Aneurysm IV: Nursing Management01:22

Aneurysm IV: Nursing Management

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
Aneurysm III: Interprofessional Care01:26

Aneurysm III: Interprofessional Care

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...

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...

Imaging Studies VII: Vascular Imaging

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
Imaging Studies for Cardiovascular System III: X-Ray01:20

Imaging Studies for Cardiovascular System III: X-Ray

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
Aneurysm II: Clinical Manifestations and Diagnostic Studies01:21

Aneurysm II: Clinical Manifestations and Diagnostic Studies

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

Radiation exposure for operating teams during endovascular aortic repairs is higher for thoracic procedures. Digital subtraction angiography runs and C-arm obliquity predict operator dose, emphasizing the need for radiation safety measures.

Area of Science:

  • Medical Imaging
  • Interventional Radiology
  • Radiation Safety

Background:

  • Endovascular aortic repairs are increasingly common.
  • Radiation exposure is an occupational hazard for healthcare professionals in interventional radiology.
  • Minimizing radiation dose is crucial for the safety of the operating team.

Purpose of the Study:

  • To quantify radiation exposure for the operating team during endovascular aortic procedures.
  • To identify factors contributing to high radiation doses.
  • To inform strategies for radiation dose reduction.

Main Methods:

  • Prospective study using electronic dosimeters placed over and under lead garments.
  • Radiation exposure recorded during endovascular aortic repairs.
  • Univariate and multivariate regression analyses to identify predictors of exposure.

Main Results:

  • Thoracic endovascular aortic repairs resulted in significantly higher operator radiation exposure (421.0 µSv) compared to infra-renal repairs (52.5 µSv).
  • Under-lead exposure for the operator and assistant was low, generally within effective dose limits.
  • Procedure type, digital subtraction angiography (DSA) time, and C-arm angulation (left anterior oblique) predicted operator dose.

Conclusions:

  • Thoracic procedures, DSA utilization, and C-arm angulation are key predictors of radiation exposure.
  • Understanding scatter radiation is essential for developing effective radiation protection strategies.
  • Mandatory implementation of measures to minimize radiation exposure is recommended.
