Superior vena cava obstruction and dissecting aortic aneurysm
JAMA
|July 14, 1975
Insights
Aortic dissecting aneurysms can cause rare and serious complications, including a fistula to the left atrium and superior vena cava obstruction. This unique clinical syndrome has not been previously reported in medical literature.
Area of Science:
- Cardiovascular Surgery
- Thoracic Aneurysms
- Aortic Pathology
Background:
- Dissecting aneurysms of the aorta are serious cardiovascular events.
- Fistula formation and vena cava obstruction are rare but critical complications.
Purpose of the Study:
- To report a unique clinical syndrome involving a dissecting aortic aneurysm.
- To describe the formation of a left atrial fistula and superior vena cava obstruction secondary to aortic dissection.
Main Methods:
- Case report detailing a patient with a dissecting aortic aneurysm.
- Clinical and pathological findings associated with the described syndrome.
Main Results:
- A dissecting aneurysm of the aorta was identified as the cause of the patient's condition.
- A fistula formed between the aneurysmal sac and the left atrium.
- Obstruction of the superior vena cava occurred due to the aneurysm.
Conclusions:
- This specific combination of aortic dissection, left atrial fistula, and superior vena cava obstruction represents a previously undocumented clinical syndrome.
- Highlights the complex and potentially life-threatening manifestations of aortic aneurysms.
Abstract:
A dissecting aneurysm of the aorta led to formation of a fistula from the aneurysmal sac to the left atrium and caused obstruction of the superior vena cava. We do not know of any previous reports of this clinical syndrome.

01:12Arteries 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...
01:27Atherosclerosis II: Clinical Manifestations and Diagnostic Tests
Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...
01:30Peripheral Artery Disease I: Introduction
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...
01:21Peripheral 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...
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...
01:20Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
