Out of more than 100 cases of TAE performed in our hospital, we have treated some cases of skin or muscle necrosis that resulted from embolization of the main arteries. In this study, we report the case of a patient with significant chest wall necrosis after TAE of the bilateral internal mammary arteries (IMAs). A 66-year-old male was transported to our hospital for loss of consciousness while playing golf. Cardiopulmonary resuscitation (CPR) was performed for cardiac arrest, which resulted in several rib fractures and mediastinal hematoma due to bilateral mammary artery injuries. Immediate TAE embolization was performed because of continuous hemorrhage. He was referred to our department 16 days after embolization due to the presentation of chest wall necrosis. Heart, lungs and diaphragm were exposed after surgical debridement under systemic anesthesia. We performed several operations to reconstruct the anterior chest wall. His spontaneous respiration returned, and is now controlled with a tracheostomy tube. Complete epithelialization was achieved, and he was transferred to another hospital for further rehabilitation. To the best of our knowledge, this is the first report of chest wall necrosis resulting from TAE of IMAs. Arterial embolization can cause widespread necrosis of bone, muscle and skin. Although treatment required an extended period, we managed to reconstruct the chest wall with multidisciplinary strategies.展开更多

Further, there has been no exclusive data or experience with minimally invasive coronary artery bypass grafting in left main stem disease. Methods: From April 2019 to March 2024, 41 patients with left main stem stenosis, left main equivalent disease and unprotected left main with triple vessel disease underwent off pump minimally invasive multivessel coronary artery bypass grafting using either in situ pedicled Bilateral Internal Thoracic arteries or Left and Right Internal Thoracic artery Y composite conduits at three centers. Bilateral Internal Thoracic arteries were harvested under direct vision. All patients had an Intra-Aortic Balloon Pump inserted via the femoral artery prior to induction of anesthesia, to prevent any hemodynamic instability, arrhythmias, and was removed following completion of the procedure in the operating room without any complications. Efficacy and outcomes were evaluated by i) Primary (MACCE)-Major Adverse Cardiac and Cardiovascular events and ii) Secondary outcome measures including total length of stay, return to full physical activity and quality of life. Mean follow-up was 1.4 years (Maximum was 2.5 years). Results: 41 patients with left main stem coronary artery stenosis, underwent total arterial revascularization using bilateral internal thoracic arteries. Left main stem stenosis was present in 29 patients, Unprotected left main stem stenosis with triple vessel disease in 7 and left main equivalence in 5 patients. In this cohort, 29 patients with only left main stem stenosis had 2 grafts each, 7 patients with left main and triple vessel disease had 3 grafts and 5 patients with left main equivalent disease had 2 grafts respectively. The average number of grafts was 2.2. One patient was converted to open sternotomy as an emergency because展开更多

This study evaluated the sequential bilateral internal mammary artery grafting combined with selective arterialization of the coronary venous system during OPCAB.Methods From April 2004 to August 2010, patients with diffuse right coronary lesions were studied retrospectively and divided into two groups. Group 1 included seventeen patients who underwent this surgery while group 2 included twenty-one patients without right coronary artery surgical therapy. All patients presented with symptoms of angina. Blood flow of bridged vessels was measured. The perioperative ventricular parameters including left ventricular ejection fraction and end diastolic diameter were compared. During follow-up, myocardial nuclide imaging and coronary angiography were carried out.Results Off-pump coronary artery bypass was performed with an average of 3.6 grafts per patient. Hospital mortality was zero. At the time of follow-up, the patients in group 1 recovered better than in group 2 （P〈0.05）. In both groups, the mean New York Heart Association （NYHA） class and ejection fraction increased significantly （P〈0.001） and the mean left ventricular end-diastolic diameter decreased significantly （P 〈0.05）. Myocardial blood supply of inferior wall in group 1 was obviously improved by myocardial nuclide imaging. Coronary angiography for eight patients in group 1 verified that there was blood flow to myocardium in the arterialized vein.Conclusions Sequential bilateral internal mammary artery grafting combined with selective arterialization of the coronary venous system can be performed during OPCAB. A postoperative improvement in the cardiac functions and the quality of life was documented, increasing our expectation for extensive application.展开更多
文摘目的分析使用双侧乳内动脉(BIMA)行冠状动脉旁路移植术(CABG)后的早期临床及CT结果和桥血管流量,探讨手术的安全性、有效性及桥流量特点。方法回顾性分析2015年12月至2016年7月我院使用双侧乳内动脉行CABG 52例患者的临床资料,其中男46例、女6例,平均年龄(56.6±6.8)岁。所有患者均在体外循环下进行,带蒂方式获取双侧乳内动脉,根据靶血管情况设计搭桥路径。完成吻合后,取平均动脉压70 mm Hg时使用Veri Q系统行桥血管即时流量测定。出院前行冠状动脉CT检查,评估桥血管通畅情况。评价围术期结果、早期CT结果及桥流量。结果无手术死亡。平均手术时间(4.7±0.6)h,平均体外循环时间(114.8±20.6)min,平均主动脉阻断时间(82.8±17.6)min,平均呼吸机使用时间(17.6±10.5)h,平均ICU停留时间(2.7±1.8)d。平均远端吻合口数(4.6±0.8)个。1例患者出现胸骨松动、伤口愈合不良,行清创缝合后治愈,其余患者无手术并发症,均康复出院。左乳内动脉桥平均流量(28.1±11.4)ml/min,平均搏动指数2.2±0.6;右乳内动脉桥平均流量(27.3±12.0)ml/min,平均搏动指数2.4±0.8;大隐静脉桥平均流量(41.5±21.5)ml/min,平均搏动指数2.2±0.7。左乳内动脉桥与右乳内动脉桥平均流量差异无统计学意义(P=0.978)。左乳内动脉桥、右乳内动脉桥平均流量分别与大隐静脉桥平均流量比较,差异有统计学意义(P=0.000)。出院前CT显示无桥血管狭窄出现;7支静脉桥、5支动脉桥吻合口远端显影浅淡,但仍通畅;2支静脉桥未显影,提示桥血管闭塞。结论使用BIMA行CABG,手术安全性高、并发症少;双侧乳内动脉桥流量相当,动脉桥早期无狭窄闭塞,是稳定理想的冠状动脉旁路移植物。
