摘要
目的：探讨超声检查显示副肝静脉（AHV）的分布规律及其血流状态。方法：随机选健康查体者800例行超声检查，取剑突下纵切、右腋前线纵切、横切和中上腹部横切、肋间斜切，观察AHV的汇入部位、走向、数量、内径及其与下腔静脉（IVC）轴线的夹角及多普勒波形、流速等。结果：800例体检者超声检查490例显示568支AHV，平均（0.80±0.38，0～3）支/例，平均内径（0.35±0.16）cm。检出一支者343例，占70％，检出两支者120例，占24.5％，检出三支者27例，占5.5％。230例显示较粗大的肝右后静脉298支，平均内径（0.40±0.19）cm，多为右或右前走行；尾状叶静脉270支，平均内径（0.26±0.18）cm，均为左走行或左前走行。AHV与IVC夹角多呈直角或近似直角（505/568，89%），平均内径（0.36±0.17）cm；63例与IVC夹角呈锐角（11%），平均内径（0.26±0.12）cm。彩色多普勒显示为与心动周期相符的双向三峰波，平均流速（12±4）cm/s。结论：超声检查可显示健康人生理状态下的部分AHV。临床检测AHV可为肝外科手术策略的制定及Budd-Chiari综合征的分型、治疗提供指导意义。
Abstract
Objective: To observe the blood distribution and blood flow state of accessory hepatic veins（AHV） by ultrasound. Methods: Eight hundred normal cases were chosen randomly for study. Ultrasound was carried out in vertical section at xiphoid process, cross section at middle abdomen, and coronary section at the waist to detect the presence of AHV. The function site, number of AHV, caliber, flow velocity and the angle between AHV and IVC were investigated. Result: There were 568 AHVs in 490 of the 800 cases, with an average of (0.80±0.38)branch?蛐case(range 0～3), average caliber is (0.35±0.16)cm. One branch of AHV has been showed in 343 cases(70%). Two branches of AHV have been showed in 120 cases(24.5%). Three branches of AHV have been showed in 27 cases(5.5%). There were 298 of inferior right hepatic veins in 230 cases. The average caliber was (0.40±0.19)cm, and 270 caudate veins were found. The average caliber was (0.26±0.18)cm. Most of the angle between IVC and AHV are right angle or close to right angle(89%, 505/568). The average caliber was (0.36±0.17)cm. A small part of them were acute angle(11%, 63/568), average caliber was (0.26±0.12)cm. The Doppler form is double direction three peak, the average speed is (12±4)cm/s. Conclusion: Ultrasound can display AHV in its physiologic condition. It is important for liver surgery, important for classification, as well as for the therapy of Budd-Chiari syndrome.
