Increased hospital costs are associated with low skeletal muscle mass in patients undergoing elective open aortic surgery

Objective

Low psoas muscle area is shown to be an indicator for worse postoperative outcome in patients undergoing vascular surgical. Additionally, it has been associated with longer durations of hospital stay in patients with cancer who undergo surgery and subsequently greater health care costs in Europe and the United States. We sought to evaluate this effect on hospital expenditure for patients undergoing vascular repair in a health care system with universal access.

“Cheese Wire” Fenestration of Dissection Intimal Flap to Facilitate Thoracic Endovascular Aortic Repair in Chronic Dissection

Thoracic endovascular aortic repair (TEVAR) for aneurysmal chronic dissection is often complicated by retrograde filling of the false lumen and dissected distal landing zone. A “cheese wire”-style fenestration of the dissection intimal flap can create a landing zone facilitating TEVAR. This technique successfully aided TEVAR in 3 patients with an average age of 57.3 years. Complications included type III endoleak requiring relining and renal artery occlusion requiring stent placement. Average duration of clinical follow-up was 19 ± 4 months. Imaging follow-up was 8 ± 10 months. All patients have survived for more than 1 year without aneurysm enlargement.

Congenital quadricuspid aortic valve with tetralogy of Fallot and pulmonary atresia

We report the case of a 4-year-old girl who had quadricuspid aortic valve regurgitation with tetralogy of Fallot and pulmonary atresia. This combination is very uncommon. Aortic valve replacement was performed successfully due to aortic regurgitation which had progressed one year after the total repair. The dilated aortic annulus plus quadricuspid aortic valve may result in progressive aortic regurgitation for a short period.

载瘤动脉闭塞术治疗颅内巨大动脉瘤的探讨

目的总结和探讨脑血管造影和载瘤动脉闭塞在治疗颅内巨大动脉瘤上的作用及特点。方法60例颅内巨大动脉瘤患者,根据其脑血管造影的特点采取血管内介入方法[可脱式球囊和(或)弹簧圈]闭塞载瘤动脉近端53例、闭塞载瘤动脉两端后孤立动脉瘤7例;其中23例闭塞前先行颅内-外血管搭桥术。结果出院时Rankin评分分级:单纯血管内介入治疗组37例中轻残3例,合并颅内-外血管搭桥术组23例中死亡1例、重残2例。1-6年的影像学随访动脉瘤无复发。结论血管内介入结合颅内-外血管搭桥术闭塞载瘤动脉是治疗颅内巨大动脉瘤的方法之一。     

Fatal thromboembolic complications following assault in a subject with an abdominal aortic aneurysm

A 62-year-old male with no significant medical history developed thromboembolic complications in the lower limbs shortly after an assault which involved punching and kicking to the trunk. Laparotomy revealed intra-abdominal injuries and an abdominal aortic aneurysm. Death from multi-organ failure and sepsis occurred 9 days post-injury. The discussion concentrates on blunt force trauma to the abdominal aorta, specifically on causation, mechanisms of injury and complications.     

室间隔夹层瘤的超声诊断(附4例报告)

目的 总结室间隔夹层瘤的超声心动图诊断及临床应用价值。方法1985～2005年超声诊断罕见的室间隔夹层瘤4例。超声主要取左室长轴、四腔心、五腔心、大动脉短轴及非标准切面，观察主动脉窦的形态及结构：如扩张窦瘤的大小、窦壁厚度、窦瘤破口的部位、窦瘤破口与室间隔之间的关系，主动脉窦瘤与室间隔夹层瘤之间交通口的大小，测量形成室间隔夹层瘤的大小及夹层瘤左、右室面的厚度，结合彩色多普勒观察心动周期夹层瘤与主动脉窦瘤血流动态变化，频谱多普勒测量窦瘤与室间隔夹层瘤之间的血流速度。结果4例室间隔夹层瘤均为主动脉右窦破人室间隔基底段，且均行手术治疗证实超声诊断。结论超声心动图对室间隔夹层瘤可直接做出诊断，超声诊断价值在于早发现、早诊断、及早治疗，并可为外科选择手术方式提供重要的有价值的依据。     

Comparative early and midterm results of open juxtarenal and infrarenal aneurysm repair

Background and aims Since the introduction of endovascular aortic aneurysm repair (EVAR) for aortic aneurysms, the number of juxtarenal aortic aneurysms (JRA) has been growing steadily due to selection bias (neck morphology for EVAR). This case-match study compares the perioperative outcome and midterm results of suprarenally clamped JRA with infrarenal aortic aneurysms (AAA). Methods From 1997 to 2004, patients who received open surgery with suprarenal clamping for JRA were included in the study and compared to matched patients with infrarenal clamping (AAA). Measurements analyzed were the in-hospital mortality and morbidity. Midterm results were obtained through clinical investigation and magnetic resonance angiography imaging. Results Thirty-five patients (mean age, 68.4 years; 30 male and 5 female) received suprarenal cross-clamping for JRA. The overall in-hospital mortality for JRA and for the controls (AAA) with elective aortic repair was 4.5% (6.1% JRA; 3% AAA, p = 0.058). The morbidity of JRA was elevated according to the rate of pulmonary complications (p = 0.021) and the need for re-operation (p = 0.019). The mean follow-up time was 2.3 years (range, 8–96 months). At follow-up, 28 patients (80%) from the JRA group and 29 patients from the AAA group (82.9%) were alive. Conclusion Open aortic surgery for JRA with the need for suprarenal cross-clamping shows a slightly elevated in-hospital mortality rate without statistical significance and equal midterm mortality results in comparison with infrarenally clamped aortic aneurysms.
