Insights

Anatomical variations of the celiac trunk and its branches are common, with non-classical trifurcation patterns observed in most cases. Preoperative identification of these variations is crucial for interventional procedures.

Area of Science:

  • Vascular anatomy
  • Radiology
  • Surgical anatomy

Background:

  • Anatomical variations of the celiac trunk (CeT) and its branches are critical for interventional procedures.
  • Understanding these variations aids in surgical and radiological planning.

Purpose of the Study:

  • To evaluate the variations and prevalence of the celiac trunk (CeT) and its branches.
  • To compare findings with classical classification methods and define a new model.

Main Methods:

  • Retrospective analysis of 941 adult patients' computerized tomography-angiography (CT-A) findings.
  • Evaluation of CeT and common hepatic artery (CHA) variations based on branch number and origin.
  • Comparison with existing classification systems.

Main Results:

  • A normal trifurcation pattern was observed in 90.9% of cases, with 82.1% exhibiting non-classical variations.
  • Rare variations included double bifurcation (0.1%), celiacomesenteric trunk (0.42%), and independent origins from the abdominal aorta (0.7%).
  • Michels Type I CHA anatomy was present in 65.5% of patients, with 5.2% being ambiguous.

Conclusions:

  • Preoperative identification of CeT, superior mesenteric artery, and CHA variations is vital for surgical and radiological interventions.
  • CT-angiography allows for the detection of rare anatomical variations.
  • A new classification model for CeT variations has been proposed.

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

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...

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...
