This paper reported the results of nonanatomic hepatic resection in 9 cases with hepatic carcinoma using ultrasound-guided rank hook needles designed by the authors. By using intraoperative ultrasonography to define the position of the tumor and the range of hepatic resection, we punctured the rank hook needles through the liver along the inside of the defined range, led thread and made a row of mattress sutures, then resected, the diseased portion of the liver without ligating portal vascular structure....

This paper reported the results of nonanatomic hepatic resection in 9 cases with hepatic carcinoma using ultrasound-guided rank hook needles designed by the authors. By using intraoperative ultrasonography to define the position of the tumor and the range of hepatic resection, we punctured the rank hook needles through the liver along the inside of the defined range, led thread and made a row of mattress sutures, then resected, the diseased portion of the liver without ligating portal vascular structure. This method can reduce blood loss, operative complications, and preserve more functional liver parenchyma.

本文报告术中B超引导应用作者设计的排式钩针作不规则肝切除9例。B超确定肿瘤的具体位置和拟定肝切除范围,用排式钩针沿拟定切线内侧穿过肝脏引线,作成一排褥式缝合,切肝时不需要阻断肝门血管。这种切肝方法可减少术中出血和手术并发症,能多保留有功能的肝组织。

l-(2,6-dimethylphenoxy)-2-(3, 4-dimethoxyphenylethylamino) propane hydrochloride (DDPH) is a new synthetic compound with the selective α1 adrenoceptor blocking effects and calcium antagonistic action. The effects of DDPH on portal hemodynamics were studied in the normotensive Wistar rats and cirrhotic dogs. DDPH (4 mg·kg-1 iv) could completely antagonize the contractive effects of phenylephrine (0.4 mg·kg-1 iv) on the portal vascularbeds in rats. DDPH (0.5 mg·kg-1 iv infusion) decreased the portal...

l-(2,6-dimethylphenoxy)-2-(3, 4-dimethoxyphenylethylamino) propane hydrochloride (DDPH) is a new synthetic compound with the selective α1 adrenoceptor blocking effects and calcium antagonistic action. The effects of DDPH on portal hemodynamics were studied in the normotensive Wistar rats and cirrhotic dogs. DDPH (4 mg·kg-1 iv) could completely antagonize the contractive effects of phenylephrine (0.4 mg·kg-1 iv) on the portal vascularbeds in rats. DDPH (0.5 mg·kg-1 iv infusion) decreased the portal vein resistence and lowered portal hypertension significantly in the cirrhotic dogs. However, there were no significant changes in hepatic arterial and portal vein blood flow in the cirrhotic dogs.The results indicated that in the portal vascular beds the physiological contractive function was mediated mainly by a, adrenoceptors. DDPH which has both the a, adrenoceptor blocking effect and the calcium antagonistic action could reduce the portal vein resistence and portal hypertension. The latter effect may have clinical significance in portal hypertension.

本文观察了DDPH对正常大鼠及肝硬化模型犬门静脉血液动力学的影响,发现DDPH能阻断α_1受体激功剂脱羟肾上腺素(Phen)对大鼠门静脉血管床的收缩作用,DDPH能明显降低肝硬化犬的门静脉血管阻力及门静脉压力,结果证明肝脏门静脉血管床以α_1受体调节为主,DDPH通过阻断门静脉血管床的α_1,受体,而发挥其降低犬硬化肝脏的门静脉血管阻力及门静脉压力的作用。

This study investigated the effects of verapamil on hepatic and systemic hemodynamics in dogs with cirrhosis and portal hypertension.The verapamil caused a signif icant reduction in arterial blood pressure and hepatic arterial resistance.However,no benefi cial effect was noted on portal venous pressure,portal venous blood flow and portal vascular resistance.This study suggests that verapamil is of no beneficial effect in dogs with cirrhosis and potal hypertension.Our results do not support the use of...

实验观察了异搏定对肝硬变门脉高压症狗肝脏和全身血液动力学的影响。结果表明:异搏定显著降低腹主动脉压和肝动脉血流阻力,而对门脉压、门脉血流量及门脉血流阻力均无明显影响。说明异搏定对肝硬变门脉高压症肝脏血液动力学影响较小,而对全身血液动力学有明显作用。提示异搏定对肝硬变狗肝脏血液动力学无任何有益作用,结果不支持异搏定用于肝硬变门脉高压症的治疗。
