Summary
Endovascular aneurysm sealing (EVAS) can rarely lead to type B aortic dissection. Prompt recognition and treatment of this rare complication are crucial for successful patient outcomes.
Area of Science:
- Vascular Surgery
- Endovascular Interventions
- Aortic Disease
Background:
- Endovascular aneurysm sealing (EVAS) aims to overcome anatomical limitations of traditional endovascular repair for abdominal aortic aneurysms.
- EVAS is increasingly used, particularly for patients with common iliac aneurysms, showing good long-term durability.
- Known EVAS complications include endoleaks, renal artery, and limb thrombosis.
Observation:
- This report details a novel and rare complication: type B aortic dissection following EVAS.
- The case highlights the importance of recognizing unusual complications after EVAS.
Findings:
- A patient developed progressive type B aortic dissection after EVAS.
- Successful emergency management involved thoracic endovascular aortic repair and carotid to subclavian bypass.
- The patient recovered well and returned to baseline function.
Implications:
- Aortic dissection is a serious, potentially catastrophic complication of EVAS.
- Vigilance and prompt diagnosis are essential to prevent adverse outcomes.
- This case expands the known spectrum of EVAS complications.

405
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...

467
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...

289
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...

01:15Aortic Regurgitation I: Introduction
584
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...

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...

Overview
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
