Summary
Surgically treated acute type A dissection (AAD) patients in the Netherlands had a 22.1% in-hospital mortality rate. Preoperative malperfusion was the only independent predictor of early death, but three-year survival for hospital survivors was high.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Vascular Surgery
Background:
- The Health Council of the Netherlands highlighted a lack of data on acute type A dissection (AAD) surgical outcomes in the country.
- This study aimed to address this gap by examining AAD surgical results in the Netherlands.
Purpose of the Study:
- To identify predictors of in-hospital mortality in surgically treated AAD patients.
- To assess the three-year survival rates for these patients.
Main Methods:
- Retrospective analysis of 104 consecutive patients undergoing AAD surgery between 1990 and 2006.
- Evaluation of preoperative and intraoperative variables to determine early mortality predictors.
- Multivariate logistic regression was used to identify independent predictors.
Main Results:
- In-hospital mortality was 22.1%.
- Preoperative malperfusion (limb or mesenteric ischemia) was the sole independent predictor of in-hospital mortality (p=0.004).
- Overall three-year survival was 68.8%, while hospital survivors achieved an 88.3% three-year survival rate.
Conclusions:
- The in-hospital mortality rate for AAD surgery in this Dutch cohort is comparable to international findings.
- Successful surgical treatment of AAD offers a relatively good long-term prognosis, with high survival rates for those who recover from initial hospitalization.

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...

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...
01:15Aortic 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...
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...
01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
01:17Aortic Regurgitation IV: Nursing Management
A nurse managing a patient with aortic regurgitation begins with a comprehensive assessment, including a review of the patient's medical history, family history, and lifestyle factors. During the cardiac examination, the nurse listens for heart sounds and checks for signs of valve abnormalities. The nurse also observes for symptoms such as dyspnea, orthopnea, and paroxysmal nocturnal dyspnea and assesses the patient's endurance and daily activity tolerance.Based on the findings, the nurse...
