【摘要】 目的 探討主動脈竇瘤破裂（RSVA）的臨床特點、診斷及外科治療方法。 方法 2004年1月-2009年12月對28例RSVA患者在體外循環下行RSVA修補術，同期行室間隔缺損修補術18例，房間隔缺損修補術4例，主動脈瓣成形術2例，主動脈瓣置換術4例。術后隨訪3個月～6年，平均32.4個月。 結果 28例患者均無手術死亡和殘余分流。失訪4例。心功能Ⅰ級20例，Ⅱ級4例；復查心臟彩色超聲心動圖無主動脈竇瘤復發或殘余分流，主動脈瓣輕-中度反流2例。 結論 外科手術是RSVA的最有效治療方法，竇瘤破口直徑gt;0.5 cm者宜用補片修補。伴有中或重度主動脈瓣關閉不全時需根據主動脈瓣病變程度以及手術者經驗決定，必要時需放寬換瓣指征。【Abstract】 Objective To evaluate the clinical characteristics, diagnosis, and surgical treatment of ruptured sinus of Valsalva aneurysm (RSVA). Methods Twenty-eight patients with RSVA were treated surgically in extracorporeal circulation. Repair of RSVA with patch were taken in all patients while closure of ventricular septal defect (VSD) in 18 patients, closure of atrial septal defect (ASD) in four patients, aortic angioplasty (AA) in two patiens and replacement of aortic valve in four patients. Results There was no death and no residue leak after operation. The patients were followed-up for 24 patients, ranged from three months to six years, with the average 32.4 months. The cardiac function of 20 patients was found to be of NYHA classⅠand four patients of classⅡ. Review the heart colour echocardiography, there was no residual tumor or sinus and aortic regurgitation light-moderate in two patients. Conclusions Surgery is the most effective treatment for RSVA, the breaches of sinus tumor in diametergt;0.5 cm is used to repair. When the patients with moderate or severe aortic regurgitation, whether it is necessary to relax in disc indications depends on the degree of aortic disease and performer’s experience.
ObjectiveTo evaluate the safety and efficacy of total arterial off-pump coronary artery bypass grafting (OPCABG) using a left internal thoracic artery (LITA) combined with bilateral radial arteries (RAs). MethodsWe retrospectively analyzed the clinical data of patients with severe multi-vessel coronary artery disease who underwent total arterial OPCABG with a LITA and bilateral RAs at Sichuan Provincial People’s Hospital from November 2020 to April 2023. Results A total of 24 patients were included, comprising 23 males and 1 female, with a mean age of (53.63±4.33) years. The New York Heart Association (NYHA) functional class was Ⅱ to Ⅲ. The mean number of distal anastomoses was 3.17±0.38. A Y-graft was constructed in 12 patients and sequential grafting was performed in 4 patients. Concomitant procedures included coronary endarterectomy in 1 patient, intra-aortic balloon pump (IABP) implantation in 10 patients, and thymoma resection in 1 patient. The mean operative time was (308.13±30.39) min, mechanical ventilation time was (15.42±7.42) h, ICU stay was (46.08±27.32) h, and postoperative hospital stay was (11.71±1.90) d. There were no in-hospital deaths. Postoperative complications included one patient of acute renal failure and one patient of cerebral infarction. Pre-discharge color Doppler echocardiography revealed that the left ventricular end-diastolic diameter was significantly smaller than before surgery (P<0.05), while the left ventricular ejection fraction and fractional shortening were significantly higher (P<0.05). Coronary computed tomography angiography (CTA) showed that all arterial grafts were patent. During a mean follow-up of (14.58±8.75) months, no patients experienced angina recurrence or mortality. Repeat coronary CTA or angiography in 16 patients one year postoperatively confirmed that all arterial grafts remained patent. Conclusion Total arterial OPCABG using a LITA and bilateral RAs is a safe and effective treatment for patients with severe multi-vessel coronary artery disease. For high-risk patients, intraoperative IABP support is recommended.
