Summary
Accessory renal arteries, variations in kidney blood supply, were found in 36.1% of Caribbean individuals. This prevalence data is crucial for planning vascular and urologic procedures in this population.
Area of Science:
- Anatomy
- Vascular Surgery
- Urology
Background:
- Accessory renal arteries are common variations in renal arterial supply.
- Prevalence data for these anomalies is lacking for Caribbean populations.
- Understanding ethnic variations is important for surgical planning.
Purpose of the Study:
- To determine the prevalence of accessory renal arteries in a Caribbean population.
- To document the origin and location of accessory renal arteries in this demographic.
Main Methods:
- Retrospective review of 302 CT scans performed between July 2010 and June 2012.
- Detailed documentation of renal arterial anatomy, specifically accessory renal arteries.
- Analysis of accessory artery presence, laterality, origin, and location.
Main Results:
- Accessory renal arteries were identified in 36.1% of evaluated CT scans.
- Left-sided accessory arteries were more common (23.5%) than right-sided (17.9%).
- The abdominal aorta was the most frequent origin (99.1%), with polar locations being most common.
Conclusions:
- This study provides the first population-based data on renal arterial anomalies in a Caribbean population.
- The high prevalence of accessory renal arteries has significant implications for vascular and urologic procedures.
- Findings highlight the need for tailored surgical approaches based on ethnicity.

01:19Imaging 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...

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
01:28Imaging 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...

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...
01:25Imaging 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...
01:10Computed Tomography
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
