Summary
Identifying risk factors for in-hospital preoperative rupture in hyperacute type A aortic dissection (haTAAD) is crucial. High serum phosphorus levels, age, and hypotension are key predictors in a new risk model.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Vascular Surgery
Background:
- Hyperacute type A aortic dissection (haTAAD) carries a high risk of in-hospital preoperative rupture.
- Predicting this rupture is essential for timely surgical intervention and improved patient outcomes.
Purpose of the Study:
- To identify risk factors associated with in-hospital preoperative rupture in haTAAD patients.
- To develop a prediction and risk stratification model for haTAAD rupture.
Main Methods:
- Retrospective analysis of 830 haTAAD patients from January 2011 to December 2019.
- Logistic regression and best subset selection for feature identification.
- Receiver Operating Characteristic (ROC) curve analysis to establish a predictive model.
Main Results:
- Key risk factors identified include advanced age, winter season, back pain, preoperative hypotension, low albumin-globulin ratio, and elevated serum phosphorus.
- A nomogram incorporating these six variables demonstrated an Area Under the Curve (AUC) of 0.828.
- The model showed good fit for predicting actual in-hospital preoperative ruptures.
Conclusions:
- A predictive model for in-hospital rupture in haTAAD has been developed using logistic regression.
- Elevated serum phosphorus is a significant predictor of rupture.
- The developed nomogram can aid in risk stratification and clinical decision-making for haTAAD patients.

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
152
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...

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...

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...

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...

153
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...
