Background : pneumonectomy not only reduces the pulmonary ascular bed but also changes the position of the heart and large essels , which may affect the function of the heart 背景：肺切除不仅仅减少了肺血管床的面积，而且会导致心脏和大血管的位置改变，从而影响心脏的功能。
Due to abnormal development of the fetal heart during the first 8 weeks of pregnancy , the large vessels that take blood away from the heart to the lungs , or to the body , are improperly connected 由于在妊娠的前8周里胎儿的心脏发展异常，使得从心脏把血液送到肺或全身的大血管错误的连接。
Type 2 diabetes mellitus is well known for its association with microvascular and macrovascular complications , but it has rarely been associated with bilateral atraumatic tibial osteonecrosis and fracture 第2型糖尿病会导致小血管及大血管并发症，但罕见合并两侧胫骨非创伤性骨头坏死及骨折。
Although atypical chest pain may be debilitating , there is no objective evidence that it indicates serious heart disease , except when due to disease of the great vessels or to pulmonary embolism .尽管非典型性胸痛有损健康，由此确定其为严重心脏病缺仍乏客观证据，除非这是由大血管病变或肺栓塞所引起的。
Although there are a number of differences in the pathogenesis and clinical features of diabetic macroangiopathy and microangiopathy , these two entities often coexist and induce mutually worsening effects 尽管在糖尿病大血管病变和微血管病变上的病理和临床特征有许多不同，然而这两类病变常常同时存在并且彼此加剧。
Background and purpose ? cardioascular risk factors are suboptimally treated in diabetes , possibly because of the impression that there is a long delay between diagnosis and the deelopment of macroascular complications such as stroke 背景与目的：糖尿病的心血管危险因素尚未得到有效的处理，这可能是由于大血管并发症从出现到被诊断有很长的迟滞如卒中。
In 1995 , a tumor was found in my daughter s arm and her doctor informed our family that removing it surgically would be difficult because cutting the many blood vessels and capillaries in the arm might cause severe hemorrhaging 1995年，我大女儿手臂上生了一个瘤。医生表示这个部位开刀很麻烦，因手臂上有大血管和许多毛细血管，开刀可能会造成大出血，希望家属要做好思想准备。
Background and purpose : cardioascular risk factors are suboptimally treated in diabetes , possibly because of the impression that there is a long delay between diagnosis and the deelopment of macroascular complications such as stroke 背景与目的：糖尿病的心血管危险因素尚未得到有效的处理，这可能是由于人们通常认为，从诊断为糖尿病到出现大血管并发症（如卒中）时间间隔较长。
This model helps the students to understand the external features and internal structures of the heart , and its relation with the large blood vessels . thus a clearer conception of the routes of the systemic and pulmonary circulation can be obtained 本模型适用于普通中学、中等专业学校讲解生理解剖课时作直观教具用，主要使学生了解心脏外部形态和内部结构，以及与心脏有关的大血管，进一步了解体循环和肺循环的途径。
Further development of disseminated tumor can spread from the lungs directly penetrated the chest wall , mediastinum , heart , vascular and other neighboring tube organizations ; after blood lymphatic metastasis to other parts of the body through the respiratory tract or disseminated to other lobe 癌肿进一步发展播散则可从肺直接蔓延侵入胸壁、纵隔、心脏、大血管等邻近器管组织；经淋巴道血道转移到身体其他部位或经呼吸道播散到其他肺叶。
