Insights

A rare congenital anomaly, anomalous left common carotid artery from the pulmonary artery, was successfully treated with arterial ligation. This procedure, monitored by near-infrared spectroscopy, proved safe and feasible for the patient.

Area of Science:

  • Cardiovascular Surgery
  • Pediatric Cardiology
  • Medical Diagnostics

Background:

  • Anomalous origin of the left common carotid artery from the pulmonary artery is an extremely rare congenital condition.
  • Limited research and treatment data exist for this anomaly.
  • A 6-year-old child with a history of patent ductus arteriosus presented with occasional dizziness.

Purpose of the Study:

  • To provide insights into the management of anomalous left common carotid artery originating from the pulmonary artery.
  • To share treatment experiences and outcomes for this rare condition.
  • To highlight the safety and feasibility of surgical intervention.

Main Methods:

  • Preoperative evaluation including cerebral angiography.
  • Surgical ligation of the proximally originating left common carotid artery.
  • Intraoperative monitoring of cerebral oxygen consumption using near-infrared spectroscopy (NIRS).

Main Results:

  • The patient underwent successful arterial ligation of the anomalous left common carotid artery.
  • Postoperative follow-up for two years showed the patient in good condition.
  • Near-infrared spectroscopy monitoring guided the surgical procedure.

Conclusions:

  • Arterial ligation of the anomalous left common carotid artery is a safe and feasible treatment.
  • Careful preoperative assessment and intraoperative NIRS monitoring are crucial for successful outcomes.
  • This case contributes valuable information for managing this rare cardiovascular anomaly.

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...

The Arch of Aorta01:10

The Arch of Aorta

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Equilibrium and Balance

The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Coronary Artery Disease III: Clinical Manifestations

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...
