Summary
This case study highlights the risk of aortic thrombus after apico-aortic conduit surgery for severe aortic stenosis. Prompt anticoagulation therapy effectively resolved the thrombus, preventing thrombo-embolic events.
Area of Science:
- Cardiology
- Vascular Surgery
Background:
- Severe aortic stenosis poses significant perioperative risks, especially in patients with comorbidities like porcelain aorta and liver dysfunction.
- Apico-aortic conduit surgery is a viable option for select patients with severe aortic stenosis and prohibitive surgical risks.
- Thrombo-embolic complications remain a concern following aortic interventions.
Observation:
- An 86-year-old female with severe aortic stenosis and liver cirrhosis underwent apico-aortic conduit surgery due to porcelain aorta and liver dysfunction.
- Postoperative imaging revealed a large thrombus in the descending aorta.
- The patient received strict anticoagulation therapy post-surgery.
Findings:
- The descending aortic thrombus significantly diminished with anticoagulation.
- No thrombo-embolic events occurred during the postoperative period.
- This suggests effective management of aortic thrombus in this high-risk patient.
Implications:
- This case underscores the potential for unusual thrombus formation after apico-aortic conduit procedures.
- It emphasizes the critical role of vigilant anticoagulation management to mitigate perioperative stroke and myocardial infarction risks.
- Further research into optimal anticoagulation strategies for patients undergoing aortic interventions is warranted.

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.

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...
01:30Venous Thrombosis I: Introduction
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
