Summary
This study reports on two pediatric cases of long-segment thoracoabdominal aortic occlusion, a rare condition. Surgical arterial reconstructions successfully managed hypertension in both children, with sustained normotension during follow-up.
Area of Science:
- Cardiovascular Surgery
- Pediatric Cardiology
- Vascular Biology
Background:
- Developmental coarctation, hypoplasia, and occlusion of the abdominal aorta are rare conditions with varied causes and treatments.
- Long-segment thoracoabdominal aortic occlusion is an extreme manifestation previously unreported in pediatric patients.
Observation:
- Two pediatric patients, aged 5 and 13, presented with severe, uncontrolled hypertension due to long-segment thoracoabdominal aortic occlusion.
- Both patients underwent complex arterial reconstructions to address the aortic pathology.
Findings:
- The younger patient received an ascending thoracic aorta to infrarenal aortic expanded polytetrafluoroethylene bypass.
- The older patient underwent a distal thoracic aorto-bi-iliac artery expanded polytetrafluoroethylene bypass, including renal artery revascularization.
- No major perioperative complications occurred in either patient.
Implications:
- These cases demonstrate the feasibility and success of extensive arterial reconstructions for long-segment thoracoabdominal aortic occlusion in children.
- Surgical intervention can effectively manage hypertension and improve outcomes in pediatric patients with this rare aortic disorder.
- This report highlights novel surgical approaches for a previously undocumented pediatric condition.

01:21Aneurysm 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...
01:26Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
01:30Aneurysm I: Introduction
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
01:25Abdominal Aorta
Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.

01:15Thoracic Aorta
The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...
01:14The Aorta
The aorta is the largest artery in the human body. It originates from the left ventricle of the heart and extends down to the abdomen, where it splits into two smaller arteries. Structurally, it can be divided into four main parts: the ascending aorta, the aortic arch, the thoracic aorta, and the abdominal aorta.
The average diameter of the aorta is approximately 2-3 cm, but the size can vary depending on the section of the aorta and the individual's age, sex, and body size. The aorta is...
