Insights

Aberrant right subclavian artery causes regurgitation in cats. CT angiography aids in diagnosing and planning surgical treatment for this congenital vascular anomaly.

Area of Science:

  • Veterinary Medicine
  • Cardiovascular Surgery
  • Diagnostic Imaging

Background:

  • Congenital vascular anomalies can cause significant health issues in domestic animals.
  • Aberrant right subclavian artery (ARSA) is a rare condition that can lead to regurgitation in felines.
  • Accurate diagnosis is crucial for effective treatment planning.

Observation:

  • Three domestic shorthair cats presented with regurgitation.
  • All cats were diagnosed with megaoesophagus secondary to aberrant right subclavian artery using thoracic radiography and CT angiography.
  • One cat also had a concurrent patent ductus arteriosus.

Findings:

  • Aberrant right subclavian artery was identified as the cause of megaoesophagus in all affected cats.
  • Three-dimensional CT angiography provided detailed anatomical information for surgical planning.
  • CT angiography is effective for preoperative assessment of vascular anomalies in cats.

Implications:

  • This study highlights the importance of CT angiography in diagnosing complex congenital vascular anomalies in cats.
  • The findings support the use of advanced imaging for surgical planning in veterinary cardiology.
  • Early and accurate diagnosis can lead to improved outcomes for cats with ARSA.

Arteries of Lower Limbs01:20

Arteries of Lower Limbs

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

Arteries and Arterioles

Arteries, the vasculature responsible for transporting blood from the heart, possess robust walls capable of enduring the elevated pressures exerted by the heartbeat. Arteries near the heart are especially thick-walled and enriched with elastic fibers across their three tunics, classifying them as elastic or conducting arteries. These arteries, usually with a diameter exceeding 10 mm, are characterized by their ability to dilate in response to the blood pumped from the heart's ventricles...

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...

Overview of Systemic Arteries01:11

Overview of Systemic Arteries

The human body is a complex, well-organized machine, and at the heart of its operations lies the circulatory system. This network of blood vessels, which includes systemic arteries, plays a vital role in maintaining life by transporting nutrients, oxygen, and waste products to and from cells throughout the body.
Systemic circulation is the part of the cardiovascular system that carries oxygenated blood away from the heart to the body's tissues and returns deoxygenated blood back to the...

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Coronary Artery Disease I: Introduction

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
