The surgical treatment methods for cirrhosis patients complicated with portal hypertension are complicated.
      
In this study, we evaluated the effectiveness of a new treatment strategy: splenic auto-transplantation and oesophageal transection anastomosis on 274 patients from three aspects: clinical observation, splenic immunology and portal dynamics.
      
From 1979 to 2005, 274 cirrhosis patients with portal hypertension who underwent the new treatment strategy were followed up to observe different clinical indexes, which were then compared with those of the traditional surgery treatment.

A new method for evaluating portal systemic circulation was presented. Following transrectal administration of 99mTc - MIBI it was feasible to detect the presence of portasy-atemic shunting in both animal and patient studies. The heart -liver ratio (H/L ratio) and the portosystemic shunt index (SI) in normal controls were 0. 21±0.08 and 0. 17 ± 0. 06. Whereas in patients of liver cirrhosis with portal hypertension were 1. 12 ± 0. 18, and 0. 54 ± 0. 07 respectively. And showed a significant difference...

A new method for evaluating portal systemic circulation was presented. Following transrectal administration of 99mTc - MIBI it was feasible to detect the presence of portasy-atemic shunting in both animal and patient studies. The heart -liver ratio (H/L ratio) and the portosystemic shunt index (SI) in normal controls were 0. 21±0.08 and 0. 17 ± 0. 06. Whereas in patients of liver cirrhosis with portal hypertension were 1. 12 ± 0. 18, and 0. 54 ± 0. 07 respectively. And showed a significant difference (p<0. 01) between normal and cirrhosis group. A good correlation between the H/L, SI and the portal pressure measurement during operation (r = 0. 93) was also found. Thereby it seems that portasystemic shunting can be quantified with this radionuclide noninvasive method .

首创了用~(99m)Tc-MIBI经肛门直肠给药测定门静脉循环的核医学方法。提出以心前区与肝区放射性之比(H/L值)及经心脏分流的份额(分流指数SI值)作为衡量门脉分流的指标。动物模型实验证实该方法的可行性。正常对照组8例的H/L平均值为0.21±0.08;SI平均值为0.17±0.06。门脉性肝硬化患者H/L平均值为1.12±0.18;SI平均值为0.54±0.07。经t检验证明该两项指标二组之间差异均有非常显著意义(P<0.01)。与手术测压结果相对照,证明这些指标的准确性(r=0.93)。表明本方法学具有定量门静脉压力的潜在可能。

Forty-seven patients with suspected space-occupying lesion of liver were examined with biphasic dynamic CT,The diagnositc value of biphasic dynamic CT was discussed.The characteristic findings of PHC were tumor vascularity and vascular pooling and/or striking enhancement in the lesion in the arterial phase,and in portal phase the hyperdense areas of the lesion changed rapidly to hypodense within 3 minutes.The characteristic features of hemangioma were gradual fill-in and delay of at least 3 min before...

Forty-seven patients with suspected space-occupying lesion of liver were examined with biphasic dynamic CT,The diagnositc value of biphasic dynamic CT was discussed.The characteristic findings of PHC were tumor vascularity and vascular pooling and/or striking enhancement in the lesion in the arterial phase,and in portal phase the hyperdense areas of the lesion changed rapidly to hypodense within 3 minutes.The characteristic features of hemangioma were gradual fill-in and delay of at least 3 min before total opacification of the lesion,In determining the nature of PHC,the biphasic dynamic CT had a sensitivity of 96.8%, a specifity of 87.5% and an accuracy of 93.6%. For hemangioma, this method showed a sensitivity of 92.9%, a specifity of 96.9% and an accuracy of 95.7%,The biphsic dynamic CT had a better result than the conventional intravenous bolus method.It could be concluded that this technique was a safe,reliable,and could be performed routinely in patients with space-ocupying lesion of liver.

作者对疑有肝内占位性病变患者进行了双期动态CT检查,经证实者共47例。原发性肝癌的特征性表现是:肝动脉期病变区见肿瘤血管及血池影和/或明显增强呈高密度,门脉期则很快恢复为相对低密度。肝血管瘤的特征性表现是:病灶增强区扩散极缓慢,病变全部充满增强呈等密度至少需要3分钟。本法对原发性肝癌定性诊断的敏感性、特异性和准确性分别是96.8%、87.5%和93.6%;肝血管瘤分别是92.9%、96.9%和95.7%;均明显高于静脉团注增强CT组。本法安全可靠,临床上可以常规应用。

To brder to evaldate various imaging modalities in selecting patients for TIPSS,the authors analysed ninety cases of hepatic MRI,CT,ultrosonographic and angiographic examina- tions. In fifty of them,TIPSS procedure was proformed after the examination. The results indicated that MRI proved to be superior in identifying the hepatic vein and portal vein,whereas ultrosono- graphic examination was superior in demonstrating portal vein flow. The authors recommended that angiography should be the modality of choice in emergent TIPSS cases,MRl and ultrosonographic examinations may be used as screening method for TIPSS patients prior to the procedure.

作者分析了90例肝脏MRI、CT、超声及血管造影这四种影像检查资料,其中50例于影像检查后行TIPSS,旨在评价如何选择行TIPSS前的影像检查。结果表明:在显示肝静脉、门静脉方面,MRI具有优越性;超声在显示门静脉血流方面具有优越性。我们认为,MRI和超声为常规TIPSS前的首选影像检查方法,急诊TIPSS前则以血管造影为主。
