  ventilation perfusion
Oxygenation index, D-dimer, fibrinogen (FG), lung ventilation/perfusion (V/Q) scan and computed tomography pulmonary angiography (CTPA) were observed before anticoagulation and on day 14 after anticoagulation.
      
In these diseases, the pulmonary bloodflow is impaired by a pathologic constriction of blood vessels that may lead to right ventricular overloading as well as serious worsening of gas exchange mainly caused by ventilation/perfusion mismatch.
      
In severe chronic heart failure (CHF) the ventilatory cost of CO2 elimination during exercise (VE/VCO2) is increased, suggesting ventilation/perfusion (V/Q) mismatch.
      
Ventilation perfusion mismatch, due to inadequate perfusion of ventilated lung apices may be the most likely underlying cause of orthostatic dyspnea in patients with OH.
      
Traditional approaches to diagnosis of deep vein thrombosis and pulmonary embolism are primarily based on the results of compression ultrasonography and the ventilation/perfusion lung scan (V/Q).

Blood gas changes in 34 cases of liver cirrhosis with ascites were studied and compared with 50 normal controls. The values of PaO_2 in cirrhotic patients were below 80 mmHg, with an average of 76.9±3.73, while those in 50 controls were93.8±10,3, t=10.63 and p<0.01. The values of SaO_2 were 94.8±10.3 in cirrhotic patients, and 94.4±1.13 in 50 controls, t=3.07, and P<0.01.In the cirrhotic group, apart from the dysfunction of hepatocytes and Kupffer cells, there are also disorders of porto-pulmonary circulatory...

Blood gas changes in 34 cases of liver cirrhosis with ascites were studied and compared with 50 normal controls. The values of PaO_2 in cirrhotic patients were below 80 mmHg, with an average of 76.9±3.73, while those in 50 controls were93.8±10,3, t=10.63 and p<0.01. The values of SaO_2 were 94.8±10.3 in cirrhotic patients, and 94.4±1.13 in 50 controls, t=3.07, and P<0.01.In the cirrhotic group, apart from the dysfunction of hepatocytes and Kupffer cells, there are also disorders of porto-pulmonary circulatory shunt, intrapulmonary arterio-venous shunt, as well as abnormality of pulmonary ventilation-perfusion ratio etc. All these can induce decrease in PaO_2, SaO_2, and various acid-base inbalances, resulting in the impairment of pulmonary resistance and leading to infection and ARDS, which are the main causes of death in these patients.

对34例肝硬化伴腹水病人进行血气检查,与50名正常人进行对照。肝硬化病例P_aO_2值低于80mmHg,平均76.9±3.73,而正常人为93.8±10.3,t=10.63,P<0.01。S_aO_2为94.8±10.3,而对照组为96.4±1.13,t=3.07,P<0.01。在肝硬化,除肝细胞与枯氏细胞功能减退之外,尚有门—肺循环分流,肺内动—静脉分流、肺通气—灌注比率异常等。这些均可导致P_aO_2与S_aO_2降低,以及各种酸碱失衡。因此肺组织抵抗力降低、病人易患感染与ARDS,这些均是死亡的主要原因。

The article reports the results of 99mTc-PYP inhalation/99mTc-MAA perfusion lung scanning used in 46 patients with lung tumor confirmed by pathological findings, 43 of them suffered with various degree of ventilation/perfusion defect in tumor-bearing lung. Patients with central lung cancer ventilation and perfusion impaired dramatically. It is estimated that was related to bronchial obstruction, compression and mediasternal invasion by the tumor. 11 of 46 patients performed lung perfusion SPECT. The smallest size of detecting tumor was 2.5cm. And other 3 cases, the ventilation and perfusion function in tumor -bearing lung was slightly higher than that of opposite side, 2 of them were with COPD, in whom the opposite side lung suffered corresonding COPD lesion, and the other one the lesion was too small.

本文报告了46例经病理确诊为肺肿瘤患者的肺~(99m)Tc-PYP吸人及~(99m)Tc-MAA灌注的显像结果。发现43例病人患侧肺均有不同程度的通气、灌注受损。46例中有11例行肺灌注断层显像(SPECT)。其检测出最小的肿瘤为2.5cm。另有3例患者患肺通气、灌注功能略高于对侧。这其中有2例为COPD患者,对侧肺有相应病变,1例可能是肿瘤病变范围太小。46例患者中有21例同时行~(99m)Tc-MIBI亲肿瘤显像,其中19例阳性。这19例中17例为恶性肿瘤。作者认为肺通气、灌注显像除了能观察肿瘤的解剖病变位置外,亦可同时提供患者的分肺通气、灌注功能情况。SPECT的应用可提高对肺小肿瘤的检出率。~(99m)Tc-MIBI亲肿瘤显像可帮助术前判断肺肿物的良、恶状况。所有这些核素检查的联合应用对肺部肿瘤的诊断将提供一个较为全面的解剖、功能及定性的信息。

It is described that using 99mTc-DTPA and 99mTc-MAA to acquire a ventilation/perfusion ratio image of lungs from posterior. A color scale with black, blue, green, yellow, red and white was generated simply. According to the difference of regional color of tbe lungs, we can easily semid-quantitively evaluate the regional V/Q of the lungs. We conclude that this technique is very simple, but very useful for doctors to comment the fuction of the lungs.

介绍了一种用(~99m)Tc-DTPA和(~99m)Tc-MAA这两种临床常用的药物进行肺的通气/灌注显像.然后经过简单的处理,产生黑、蓝、绿、黄、红、白六种颜色的色阶,根据功能图像上局部肺组织的颜色差异,可以半定量地对脾的通气/血流情况进行评估,每个颜色的级差为20%,这种评估方法简便实用,值得探讨.
