Superficial Temporal Artery to Middle Cerebral Artery Bypass

The superficial temporal artery to middle artery bypass is a technique that allows the blood supply from the extracranial carotid circulation to be routed to the distal middle cerebral artery branches. The procedure allows blood flow to bypass proximal lesions of the intracranial vasculature. The performance of this bypass requires specialized microvascular training and the use of microvascular techniques. The techniques involved in performing these procedures include microdissection of the superficial temporal artery in the scalp, microdissection of the recipient middle cerebral artery branches near the sylvian fissure, and anastomosis techniques using either microvascular sutures or a microanastomotic device. The successful completion of the bypass and subsequent patency requires meticulous attention to technical details.     

自体桡动脉在不停跳冠状动脉旁路移植术中的应用

目的探讨自体桡动脉（radial artery,RA）在不停跳冠状动脉旁路移植术（off-pump coronary artery bypass graft,OPCABG）中应用的效果及安全性。方法回顾性分析我院2009年10月～2012年10月375例应用自体桡动脉（radialartery,RA）进行OPCABG的临床资料,对老年组（年龄≥60岁,n=184）及非老年组（年龄〈60岁,n=191）临床结果进行比较。结果 375例平均搭桥（3.0±0.7）支,共使用392支RA,其中右冠状动脉系统307支,前降支系统37支,回旋支系统48支。术后RA移植物相关心电图改变发生15例,无围手术期心肌梗死发生,无RA取材并发症。住院死亡率老年组为1.1%（2/184）,非老年组为1.0%（2/191）,2组比较无统计学差异（χ2=0.000,P=1.000）;主动脉球囊反搏（intra-aorticballoon pump,IABP）使用率老年组为7.6%（14/184）,非老年组为6.3%（12/191）,2组比较无统计学差异（χ2=0.255,P=0.613）;老年组住院时间（21.8±9.3）d,与非老年组（21.8±8.6）d无统计学差异（t=0.000,P=1.000）;老年组移植血管数（3.1±0.7）支,与非老年组（3.1±0.7）支无统计学差异（t=0.000,P=1.000）。273例随访3～36个月,（16.8±10.0）月,死亡5例,均为非心脏源性;23例术后残留心绞痛症状,均无心电图及影像学证据显示与RA移植物有关。结论自体RA在OPCABG中使用安全有效,有很好的近期临床效果,老年患者和非老年患者临床效果并无显著性差异。     

Thoracoscopic Bronchial Artery Resection for Multiple Bronchial Artery Aneurysms

We describe a 36-year-old asymptomatic female with multiple bronchial artery aneurysms (BAAs) and a bronchial artery (BA) to pulmonary artery (PA) fistula. She was treated with thoracoscopic BA resection without lobectomy in lieu of catheter embolization as first-line treatment. The configuration of the BA and the location of the BAAs were clearly visualized using three-dimensional computed tomography (3DCT); therefore, the segment of the BA to resect was assessed preoperatively and complete resection of all BAAs was performed. Preoperative BA angiography delineated the BA to PA fistula, and guided surgical decision-making.     

Anomalous Origin of Right Coronary Artery from Pulmonary Artery

A 67-year-old female was incidentally found to have an anomalous right coronary artery (RCA) arising from the pulmonary artery during evaluation of her aortic valve disease. The left main, left anterior descending, and circumflex coronary arteries were mildly dilated. Large collaterals from the left filled the RCA retrogradely. During surgery, a circumferential web was found at the ostia of the RCA. The patient underwent an aortic valve replacement, resection of the web, and translocation of the anomalous RCA into the aorta.     

骨骼化乳内动脉在冠状动脉旁路移植术中的应用

目的总结骨骼化乳内动脉(skeletonized internal mammary artery)应用于冠状动脉旁路移植术(CABG)的早期结果和经验。方法2004年1月至2007年6月,139例患者均于静脉复合全身麻醉、在胸部正中切口体外循环下施行CABG;应用骨骼化方法采集左乳内动脉,并与前降支吻合。结果远端吻合口数3.6±1.7个/例,无胸腔积液和胸骨感染;院内死亡2例,死亡率1.4%(2/139),1例死于脑卒中,1例死于呼吸窘迫综合征;发生并发症8例,并发症发生率5.8%(8/139),其中肺部感染3例,切口皮下感染2例,低心排血量综合征3例,均通过抗感染、换药、血管活性药物治疗等措施治愈。生存患者随访2～34个月(20.6±5.9个月),随访率80.3%(110/137);所有患者无心绞痛复发,心功能恢复至～级(NYHA)。结论在CABG中应用骨骼化乳内动脉安全、可靠,早期疗效满意。     

Influence of Coronary Artery and Contralateral Carotid Artery Status on Long-Term Results of Carotid Artery Surgery

n = 56) had an occluded contralateral carotid artery, in group II (n= 56) both carotids were operated on, and group III (n= 112) had a normal contralateral carotid artery. The clinical status of all patients except one was ascertained by one of us. We found that the status of the contralateral artery does not influence the long-term prognosis of patients undergoing carotid artery surgery. A periodic cardiological and vascular follow-up of these patients seems warranted to improve their survival.     

Open Versus Tunneling Radial Artery Harvest for Coronary Artery Grafting

Abstract We present a less traumatic surgical technique for harvesting the radial artery as a coronary artery bypass graft that does not require any special equipment or skills. We prospectively randomized 40 patients undergoing coronary artery bypass grafting with the radial artery into two groups on the basis of harvest techniques: tunneling excision and conventional open method. The less‐invasive tunneling technique is safe, easily applicable, and preferred by patients because of the superior cosmetic result . (J Card Surg 2010;25:504‐507)     

桡动脉在冠状动脉旁路移植术中的应用

桡动脉（RA）作为冠状动脉旁路移植术（cABG）的移植血管已广泛应用，但在其获取、手部侧枝循环的评估、抗痉挛措施、靶血管选择、以及近端吻合口等方面尚未统一的认识。一般认为RA应当连同周围的伴行静脉血管一起获取并且优先用于严重狭窄（〉70％）的冠状动脉。RA近端可以吻合于升主动脉，或者与左侧或右侧乳内动脉一起构成复合移植血管。RA作为移植血管的通畅率主要取决于靶血管狭窄的严重程度和靶血管的位置，而不是取决于近端吻合于主动脉或是乳内动脉。尽管缺乏实验证据，许多研究者提倡预防性抗痉挛治疗。在全动脉化冠状动脉旁路移植的患者中应用RA取代右侧乳内动脉作为第二选动脉移植血管具有优势。     

Lumbar Artery Pseudoaneurysm

Abstract Lumbar artery pseudoaneurysms following trauma are rare cases and are usually secondary to bullet wounds. The authors report a case resulting from a stab wound with concomitant through-and-through injuries to the duodenum and inferior vena cava and delayed presentation of the lumbar artery injury. The injury was successfully managed with coil embolization.
