Thoracic Aorta

Thoracic 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,...

Aneurysm 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...

Aortic Regurgitation III: Medical Management

Aortic Regurgitation III: Medical Management

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Aneurysm III: Interprofessional Care

Aneurysm 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...

Aneurysm I: Introduction

Aneurysm 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...

Aortic Regurgitation I: Introduction

Aortic Regurgitation I: Introduction

IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

Area of Science:

Vascular Surgery
Endovascular Interventions
Thoracic Aortic Pathology

Background:

Management of penetrating atherosclerotic ulcers (PAU), intramural hematomas (IMH), and acute aortic dissections (AD) of the thoracic aorta is challenging.
Endovascular approaches are increasingly utilized but outcomes for non-aneurysmal pathology require further evaluation.

Purpose of the Study:

To evaluate the safety and efficacy of thoracic endovascular aortic repair (TEVAR) for non-aneurysmal thoracic aortic pathologies.
To assess early and late outcomes, including morbidity, mortality, and complications.

Main Methods:

A cohort of 20 patients with PAU and/or IMH underwent TEVAR between 2001 and 2007.
Indications for intervention included intractable pain, hematoma expansion, or malperfusion.
Outcomes measured included early morbidity/mortality, endoleaks, device complications, and reinterventions.

Main Results:

All 20 endovascular repairs were technically successful with minimal blood loss and no 30-day mortality.
All patients experienced symptom resolution, and no neurologic complications occurred.
Mean follow-up was 2.0 years; two late deaths were unrelated to the procedure. Three early endoleaks were successfully managed, with one reintervention.

Conclusions:

TEVAR is a feasible and safe treatment option for non-aneurysmal thoracic aortic pathologies.
The procedure offers symptom resolution with no operative mortality or neurological complications.
Long-term follow-up indicates sustained positive outcomes.
