Summary
Stent grafts effectively treated two cases of visceral artery aneurysms, preserving organ blood flow. This minimally invasive approach shows promise for managing these vascular conditions.
Area of Science:
- Vascular Surgery
- Interventional Radiology
Background:
- Visceral artery aneurysms are rare but can lead to serious complications.
- Traditional surgical repair carries significant risks.
Observation:
- Two patients with visceral artery aneurysms underwent endovascular repair.
- Case 1: A 42-year-old woman with a right renal artery aneurysm treated with Wallgraft endoprosthesis.
- Case 2: A 72-year-old woman with a superior mesenteric artery aneurysm treated with Jostent stent graft.
Findings:
- Both stent graft procedures successfully excluded the aneurysms.
- Distal end-organ perfusion was maintained in both cases.
- The procedures were technically successful with no immediate complications.
Implications:
- Stent graft placement is a safe and effective treatment for select visceral artery aneurysms.
- This endovascular technique may become a preferred method for managing these aneurysms.
- Further studies are needed to confirm long-term durability and reproducibility.

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...
01:21Aneurysm 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...
01:30Aneurysm 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...
01:25Aortic 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...
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.

01:22Aneurysm IV: Nursing Management
Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
