Background: Small aortic annulus during aortic valve replacement can lead to implanting a smaller sized valve compared to the body surface area thereby causing patient prosthesis mismatch. Various aortic root enlargement techniques have been described depending on anterior or posterior approach. Konno procedure uses anterior approach for aortic root enlargement. In this study, we reviewed results of Konno procedure done from 2011 to 2019 by a single surgeon. Methods: 12 adult patients who underwent aortic valve replacement along with Konno procedure for small aortic root by a single surgeon at a single center between 2011 and 2019 were reviewed. Echocardiographic and demographic data and post-operative data were obtained from medical records. Symptomatic profile was assessed as per New York Heart Association Classification. Intraoperative findings and post-operative period findings were noted. Follow up symptom profile was assessed for these patients. Results: 12 patients underwent Konno procedure between 2011 and 2019 for small aortic root along with valve replacement. The main indication for surgery was aortic stenosis with small aortic annulus, with or without involvement of the mitral valve. Preoperatively, 3 patients had NYHA class II and 9 patients had NYHA class III symptoms. Mean age at operation was 26.42 years, minimum age 10 years, and maximum age 39 years. 3 were females and 9 were males. Mean bypass time was 106.4 minutes and aortic cross clamp time was 80.67 minutes. Mechanical aortic valves were implanted in all patients. Mean post-operative blood loss was 134.2 ml and duration of ventilation before extubation was 14.5 hours. Mean duration of intensive care unit (ICU) stay was 2.83 days and hospital stay was 9.1 days. Mean gradient in the post-operative period was 10.75 mm Hg. There was no mortality in these 12 patients and no reoperation was needed in the follow up period. Follow up in the outpatient department suggested all patients had NYHA class I symptoms and anticoagulation with warfarin adjusted to prothrombin time— International normalised ratio. Conclusion: Konno procedure is effective for managing small aortic root as bigger outflow orifice area through the larger valve prosthesis improves ventricular outflow and hence, improves the outcomes.
背景:主动脉瓣置换术中主动脉环小可能导致植入的瓣膜尺寸小于体表面积,从而导致患者假体不匹配。根据前路或后路的不同,已经描述了各种主动脉根部扩大技术。Konno手术采用前路手术治疗主动脉根部肿大。在这项研究中,我们回顾了2011年至2019年由一名外科医生进行的Konno手术的结果。方法:回顾了2011年至2019年在单一中心由同一名外科医生接受主动脉瓣置换术和Konno手术治疗小主动脉根的12例成年患者。超声心动图和人口统计资料及术后资料均来自医疗记录。根据纽约心脏协会分类对症状进行评估。记录术中及术后表现。对这些患者的随访症状进行评估。结果:2011年至2019年期间,12名患者接受了Konno手术治疗小主动脉根并进行了瓣膜置换术。手术的主要指征是主动脉狭窄伴小主动脉环,伴或不伴二尖瓣受累。术前3例出现NYHA II级症状,9例出现NYHA III级症状。平均手术年龄26.42岁,最小年龄10岁,最大年龄39岁。女性3例,男性9例。平均旁路时间106.4分钟,主动脉交叉夹持时间80.67分钟。所有患者均植入机械主动脉瓣。术后平均失血量134.2 ml,拔管前通气时间14.5小时。重症监护病房(ICU)平均住院时间2.83天,住院时间9.1天。术后平均梯度为10.75 mm Hg, 12例患者无死亡,随访期间无再次手术。门诊随访提示所有患者均有NYHA I级症状,并使用华法林调整至凝血酶原时间-国际正常化比率抗凝。结论:Konno手术是治疗小主动脉根的有效方法,通过较大的瓣膜假体扩大流出口面积,改善心室流出,从而改善预后。

Summary: The diagnosis of venous insufficiency is increasing. Multiple techniques are available for its treatment. Chemical sclerotherapy has been performed for over 70 years. The technique improves lately. Objective: This study was conducted to assess early results of foam sclerotherapy in Senegal. Patients and Methods: This is a prospective and descriptive study conducted from January 1st, 2012 to December 31st, 2015 at cardiovascular center of Fann University hospital in Dakar, Senegal. Foam sclerotherapy was done in 76 patients. Polidocanol was used in concentration of 2%. Sclerotherapy was done several times in patients, every week, as much as needed to occlude varicose veins. We used venous compression in all patients. Results: Foam sclerotherapy sessions permitted to get globally good results. In fact, tight feeling and painful leg disappear in 97% of patients. Decreases of edema were gotten in 97% of patients. For leg ulcer, 64% of complete healing was obtained. The main ulcer healing time was 47 days (18; 72). Some minor complications occurred. No major events, such as deep venous thrombosis or pulmonary embolism, were observed. Conclusion: Foam sclerotherapy is an efficient technique for the treatment of varicose veins of the limbs. Also, it opens good perspectives for vein care.

Introduction: Treatment of combined coronary artery surgery (CABG) and severe carotid artery stenosis is still controversial. The decision of surgical priority can change according to the severity of the coronary artery disease or carotid artery disease at staged surgery. The aim of the study is to compare the outcomes of simultaneous surgery (CEA + CABG) and CABG alone at our department. Materials and Methods: We retrospectively reviewed the CABG and CEA + CABG patients which were performed between 2010 and 2015. If the patients had simultaneous another operation, they were excluded from the study. A total of 294 patients (252 CABG patients and 42 combined surgery patients), were retrospectively examined. Results: Two patients in CABG group and two patients in CABG + CEA group developed stroke. There was no statistically significant difference between the two groups in terms of early stroke rate (p > 0.05). One patient in CEA + CABG group and three patients in CABG group died. The average carotid clamp time was 19.93 ± 5.06 minutes. Aortic clamp times were 42.89 ± 6.38 minutes in CABG and 42.81 ± 5.70 minutes in CEA + CABG patients. Results of the two groups were similar. Conclusion: Combined CEA and CABG can be performed successfully and safely in patients.
简介:冠状动脉联合手术(CABG)治疗严重颈动脉狭窄仍存在争议。分期手术可根据冠状动脉病变或颈动脉病变的严重程度而改变手术优先级的决定。本研究的目的是比较我科同时手术(CEA + CABG)和单独CABG的结果。材料与方法:我们回顾性分析2010 - 2015年间行CABG和CEA + CABG的患者。如果患者同时进行了其他手术,则将其排除在研究之外。回顾性分析了294例患者(252例冠脉搭桥患者和42例联合手术患者)。结果:CABG组2例,CABG + CEA组2例发生脑卒中。两组早期脑卒中发生率比较,差异无统计学意义(p > 0.05)。CEA + CABG组1例死亡,CABG组3例死亡。颈动脉夹持时间平均为19.93±5.06 min。主动脉夹钳时间CABG组为42.89±6.38 min, CEA + CABG组为42.81±5.70 min。两组结果相似。结论:CEA联合冠脉搭桥术可以成功、安全地进行。

Background: Even with the use of extracorporeal membrane oxygenation (ECMO) in acute respiratory distress syndrome (ARDS), mortality remains high. Also, prognostication of patients with ARDS and ECMO is difficult. Cytokines are thought to be markers of inflammation in both ARDS and in ECMO, however, understanding is limited. We aimed to study the association of three serum cytokine levels with mortality in these patients with ARDS on ECMO. Methods: We performed a retrospective chart review of ARDS patients on ECMO between 2011 and 2017. Patients with serum TNF-α, IL-6 and IL-2 measured while on ECMO were included, with measurements recorded weekly up to a maximum of 4 measurements. A multivariable regression analysis was performed and generalizing estimating equations were used to analyze longitudinal trend of cytokines with mortality. Results: There were 47 patients with ARDS on ECMO, of which 31 (68.9%) survived at 30 days and 2 were lost to follow up. Initial IL-2 levels were found to be significantly higher among those who were alive compared to those who died at 30 days (2720 ± 2432 pg/ml vs. 1293 ± 693 pg/ml); p = 0.0460. At any given time, an increase in IL-2 was associated with a decrease in odds of death at 30 days (adjusted odds ratio 0.98, 95% confidence interval 0.97 - 0.99, p = 0.08). There was no significant difference in average or initial levels of TNF-α and IL-6 among those who were alive vs. those who died at 30 days. There was no association between either of these cytokine levels with death while on ECMO. Conclusions: Higher levels of cytokine IL-2 were associated with lower 30-day mortality. Further studies are needed to elucidate the pathobiology of cytokines while on ECMO and their use in predicting outcomes.
背景:即使使用体外膜氧合(ECMO)治疗急性呼吸窘迫综合征(ARDS),死亡率仍然很高。此外,ARDS合并ECMO患者的预后也很困难。细胞因子被认为是ARDS和ECMO中炎症的标志物,然而,对其的理解有限。我们的目的是研究三种血清细胞因子水平与急性呼吸窘迫综合征患者ECMO死亡率的关系。方法:我们对2011年至2017年接受ECMO治疗的ARDS患者进行回顾性分析。纳入在ECMO时测量血清TNF-α、IL-6和IL-2的患者,每周最多记录4次测量。采用多变量回归分析和广义估计方程分析细胞因子与死亡率的纵向趋势。结果:47例ARDS患者采用ECMO治疗,其中31例(68.9%)30 d存活,2例失访。与死亡患者相比,存活患者的初始IL-2水平在30天内显著升高(2720±2432 pg/ml vs. 1293±693 pg/ml);P = 0.0460。在任何给定时间,IL-2的增加与30天死亡几率的降低相关(校正优势比0.98,95%可信区间0.97 - 0.99,p = 0.08)。存活组与死亡组在30天内TNF-α和IL-6的平均或初始水平无显著差异。在ECMO时,这两种细胞因子水平与死亡均无关联。结论:较高水平的细胞因子IL-2与较低的30天死亡率相关。需要进一步的研究来阐明ECMO时细胞因子的病理生物学及其在预测预后中的应用。

Background: The left internal mammary artery (IMA) is widely used as a conduit for coronary revascularization. The incidence of atherosclerosis is known to be lower in the IMA than in the coronary artery. The aim of this study was to evaluate the reliability of the use of the distal section of the IMA as an anastomotic site for bypass grafting and morphometric studies of IMA in patients with proven coronary artery disease and their associated risk factors. Methods: Patients who underwent Coronary Artery Bypass Graft (CABG) from June 2010 to November 2012 were chosen in this retrospective study and the discarded distal segments of the internal mammary artery were analyzed. The potential risk factors for atherosclerosis considered were age, sex, diabetes mellitus, history of cigarette smoking, hypertension and hypercholesterolemia. The samples were analyzed for the degree of intimal thickening and atherosclerosis by calculating the percentage of Luminal Narrowing, Intimal Thickness Index (ITI) and Intima-to-Media Ratio (IMR). Results: There were seven cases of intimal hyperplasia and two cases of focal medial and intimal hyperplasia

The infarction exclusion technique using endoventricular continuous sutures for ventricular septal rupture after acute myocardial infarction may be a difficult surgical technique and create residual shunt due to fragile myocardium. We present a patient of ventricular septal rupture (VSR) after extensive anteroseptal myocardial infarction who underwent successful repair using a modified infarction exclusion technique. In our procedure interrupted mattress sutures were placed through the ventricular wall in a way as to exclude the VSR and infarcted muscle of the left ventricle.

The evaluation of the extension of the atheromatous lesion is essential for the planning of the endovascular technique at the level of the femoral arterial bifurcation. Therefore, we changed the classification of Azema and applied it to a series of patients who had undergone open surgery of the femoral arterial bifurcation. This evaluation made it possible to have an idea of the distribution of atheromatous lesions in this region and to compare the efficiency of this modified classification of Azema with others used in the literature. This modified classification of Azema is relevant and constitutes a decision-making tool for the endovascular therapeutic indications of femoral arterial bifurcation.
动脉粥样硬化病变范围的评估对于在股动脉分叉水平的血管内技术的规划是必不可少的。因此,我们改变了Azema的分类,并将其应用于一系列接受开放手术的股动脉分叉患者。这种评价使我们有可能了解该区域动脉粥样硬化病变的分布,并将这种改进的Azema分类与文献中使用的其他分类进行比较。这种改进的Azema分类是相关的,并构成了股动脉分叉血管内治疗指征的决策工具。

Importance of thrombendarterectomy (TEA) had declined with the advent of bypass techniques and availability of prosthetic grafts, in patients with Peripheral arterial occlusive disease (PAOD). Recently, there had been a significant shift towards lower limb revascularization using endoluminal techniques. However, previously available data evaluating the long leg bypass or combined endoluminal and bypass procedures have been too anatomically heterogeneous to be easily applied to patients with infrainguinal disease and tissue loss. Clinical decision making in Complex multilevel or diffuse peripheral arterial occlusive disease with multiple co-morbidities especially associated coronary arterial disease is challenging. We describe twelve patients of iliofemoral arterial occlusive disease with tibiopopliteal arterial occlusive disease along with multiple co-morbidities like coronary arterial disease and diabetes mellitus who showed marked improvement with minimal post-operative morbidities after iliofemoral or ileopopliteal bypass grafting with endarterectomy of the tibiopopliteal segment and related review of the literature.
对于外周动脉闭塞性疾病(PAOD)患者,血栓动脉切除术(TEA)的重要性随着旁路技术的出现和假体移植物的可用性而下降。最近,使用腔内技术进行下肢血运重建术有了显著的转变。然而,先前评估长腿搭桥或腔内联合搭桥手术的现有数据在解剖学上太不一致,难以应用于腹股沟下疾病和组织丢失的患者。复杂的多级别或弥漫性外周动脉闭塞性疾病合并多种合并症,特别是与冠状动脉疾病相关的临床决策具有挑战性。我们描述了12例髂股动脉闭塞性疾病合并胫腘动脉闭塞性疾病并伴有冠状动脉疾病和糖尿病等多种合并症的患者,他们在髂股动脉或回腘动脉旁路移植术并胫腘段动脉内膜切除术后表现出明显的改善,术后并发症很少,并对相关文献进行了复习。

Role of Partial Thoracoplasty in Lung Lesions —A Single Institute Experience 部分胸廓成形术在肺部病变中的作用-一个研究所的经验

Thoracoplasty has been a useful procedure to control and cure recalcitrant lung lesions often as a last measure to treat pulmonary infections like post- tubercular chronic empyema with fibrocavitary lesions and residual pleural space infections after pulmonary resections. Long-standing empyemas with persistent discharge on drainage often respond poorly after decortication and debridement alone due to non-expanding underlying lung tissue due to fibrotic changes. These cases often develop recurrent empyemas with sepsis with high morbidity and mortality. Similarly chronic space-occupying lung lesions with adjacent pulmonary damage and fibrosis leave a considerable residual space after surgery of these lesions and these persistent residual space leads to pleural space infections and empyema. In the presence of a large apical abscess and destruction of the apical pulmonary tissue forming a potential space confined by the bony thoracic cage and limited inferiorly by the rigid lining of the abscess, the cure and management of the chronic empyema especially the post-tubercular ones are particularly difficult. We address these cases in our series by performing partial thoracoplasty tailored to the site of the lesions in addition to other procedures. Partial thoracoplasty was found beneficial for selective cases of chronic empyema, obliteration of residual cavity after resectional surgery and management of the apical abscess.
胸廓成形术一直是控制和治疗顽固性肺病变的有效方法,通常作为治疗肺部感染的最后措施,如结核后慢性脓胸伴纤维腔病变和肺切除术后残余胸膜间隙感染。由于纤维化改变导致的肺组织不扩张,长期的脓肿在单纯去皮和清创后往往反应不佳。这些病例经常发生复发性脓胸并脓毒症,发病率和死亡率都很高。同样,伴有相邻肺损伤和纤维化的慢性占位性肺病变在这些病变手术后留下相当大的残留空间,这些持续的残留空间导致胸膜间隙感染和脓胸。由于存在较大的根尖脓肿和肺根尖组织的破坏,形成了一个被胸骨笼限制的潜在空间,并被脓肿的刚性衬里限制在下方,慢性脓肿尤其是结核后脓肿的治疗和管理尤其困难。我们在我们的系列中通过根据病变部位进行部分胸廓成形术以及其他手术来解决这些病例。部分胸廓成形术对选择性的慢性脓肿、切除后残余腔的封堵和根尖脓肿的处理都有好处。

Background: The aim of this study was to evaluate the impact of additional coronary revascularization on the early results in patients submitted to valve surgery. Patients and Methods: A retrospective review of the cardiac surgical database between January 2000 and December 2018 was performed. A total of 1667 patients were included and divided into two groups: Group A isolated valve surgery (IVS n = 1608) and Group B with valve surgery combined to coronary artery bypass grafting (VS + CABG n = 59). Demographic, operative data and postoperative outcomes were compared between groups. Results: Patients with combined procedure were older than patients who underwent isolated valvular surgery (64.9 ± 9.2 years vs 44.4 ± 13.1 years; p = 0.0001) and there was a higher proportion of diabetics (40.7% vs 6.6%; p = 0.0001). The 30 days mortality rate in the combined procedure group was 18.6% versus 6.2% in isolated valve surgery (p = 0.001). Also post-operative complications were more frequent than for patients who underwent IVS. Additionally we noted a high prevalence of coronary artery risk factors in patients with combined procedures. Conclusion: Surgical mortality and morbidity of coexisting coronary and heart valve disease were substantially higher than IVS. More efforts in medical management may reduce the incidence of adverse outcomes.
背景:本研究的目的是评估额外冠状动脉血运重建术对接受瓣膜手术患者早期结果的影响。患者和方法:对2000年1月至2018年12月的心脏外科数据库进行回顾性分析。共纳入1667例患者,分为两组:A组单纯瓣膜手术(IVS n = 1608)和B组瓣膜手术联合冠状动脉旁路移植术(VS + CABG n = 59)。组间比较人口学、手术资料及术后结果。结果:联合手术患者比单独瓣膜手术患者年龄大(64.9±9.2岁vs 44.4±13.1岁;P = 0.0001),糖尿病患者比例更高(40.7% vs 6.6%;P = 0.0001)。联合手术组的30天死亡率为18.6%,而单独瓣膜手术组为6.2% (p = 0.001)。此外,术后并发症比静脉注射患者更频繁。此外,我们注意到联合手术患者冠状动脉危险因素的患病率很高。结论:合并冠心病和心瓣膜病的手术死亡率和发病率明显高于静脉注射。在医疗管理方面做出更多努力可能会减少不良后果的发生率。
