Surgical and Radiologic Anatomy : SRA
|October 11, 2002
Summary
An aberrant right subclavian artery, a rare aortic arch variation occurring in less than 1% of individuals, was identified during routine human cadaver dissection. This case report details its anatomy and embryological origins.
Area of Science:
- Anatomy
- Embryology
- Vascular Surgery
Background:
- Anatomical variations of the aortic arch branches can have clinical implications.
- The aberrant right subclavian artery (ARSA) is a rare congenital anomaly.
Purpose of the Study:
- To report a case of ARSA discovered during cadaveric dissection.
- To review the embryology and anatomy of ARSA.
- To discuss the clinical relevance of this vascular variation.
Main Methods:
- Routine dissection of 230 adult human specimens.
- Detailed description of the aortic arch and its branches.
- Comparison with existing literature on ARSA.
Main Results:
- Identification of an 82-year-old male donor with a retro-esophageal ARSA as the final branch of the aortic arch.
- The incidence of this variation is noted to be less than 1%.
Conclusions:
- ARSA is a rare aortic arch anomaly with specific embryological origins.
- Detailed anatomical description and comparison with other cases are crucial for understanding its variations.
- Awareness of ARSA is important for clinicians, particularly in vascular and cardiothoracic surgery.

01:28Esophageal Perforation-II: Clinical Manifestations and Management
Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.

01:30Esophageal Strictures-I: Introduction
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

01:26Esophageal Strictures-II: Clinical Features and Management
Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

01:24Esophageal Varices-I: Introduction
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...
01:28Esophageal Varices-II: Clinical Features and Management
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol abuse, or...

01:27Esophageal Achalasia
Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
