Insights
Giant coronary artery aneurysms (CAA) require prompt surgical intervention. This study shows successful surgical treatment with no recurrence or mortality in six patients.
Area of Science:
- Cardiovascular Surgery
- Aneurysm Research
- Cardiac Pathology
Context:
- Giant coronary artery aneurysms (CAA) are rare but serious cardiovascular conditions.
- Surgical management is crucial for these complex cases.
- Fuwai hospital has experience in treating these rare aneurysms.
Purpose:
- To review the clinical features of giant coronary artery aneurysms (CAA).
- To discuss the surgical treatments and outcomes for giant CAA.
- To emphasize the importance of early diagnosis and intervention.
Summary:
- Six patients with giant CAA underwent surgical treatment between 1996 and 2004.
- Procedures included aneurysm resection, coronary bypass, and reconstruction, often with concomitant cardiac procedures.
- All patients achieved uneventful recovery with no recurrence or mortality during a mean follow-up of 48 months.
Impact:
- Surgical intervention for giant CAA leads to favorable outcomes.
- Early diagnosis and timely surgical treatment are essential for managing this serious condition.
- This study highlights the feasibility and success of surgical repair for giant CAA.
Objective:
To discuss the clinical features and surgical treatments of giant coronary artery aneurysm (CAA).
Methods:
From July 1996 to October 2004, 6 giant CAA patients were underwent surgery at Fuwai hospital. Three cases were underwent CAA resection, 2 concomitant coronary bypass, 3 reconstruction. The giant CAA was often combined with other cardiac diseases. Four cases underwent additional procedures of fistula closure, 3 aortic valve replacements, 2 aortoplasty and 1 thrombus cleaning at the same time.
Results:
All patients recovered uneventfully. The mean of cardiopulmonary bypass time was (144 +/- 26) min (range 67 to 207 min). Aortic cross clamping time was (104 +/- 21) min (range 56 to 172 min). Patients follow-up time occurred from 8 to 87 months (mean of 48 months). All patients were free of symptoms during follow-up. None of the patients died during the follow-up period and none of the CAA recurred.
Conclusions:
The giant CAA is a serious cardiovascular disease, early diagnosis and surgical treatment are mandatory.
