To identify the frequency of different arterial variants of common hepatic artery (CHA) overview identified at abdominal CT angiography (CTA) performed in a large series of patients undergoing CT scans for various reasons.
Observational study.
Department of Surgical Oncology and Radiology, Shaukat Khanum Memorial Cancer Hospital & Research Centre, Lahore, Pakistan, from October 2016 to September 2018.
Findings in randomly selected 1000 patients who underwent CTA were retrospectively evaluated. The pattern of aortic origin of branches of the celiac trunk and superior mesenteric arteries was analysed. The CHA anatomy was then investigated. Hepatic artery anomalies were classified by the Hiatt's method.
There were 629 males and 371 females with a median age of 54 years. Type 1 variation (normal anatomy) was seen in 644 patients. Type 2 variation (left hepatic artery, LHA, aberrations), was seen in 135 patients. LHA was seen arising from left gastric artery or common hepatic artery (CHA) in most of the cases. One patient had a replaced LHA from superior mesenteric artery (SMA). Sixteen patients had an accessory LHA and 119 had a replaced LHA. Type 3 variation (unusual anatomy of right hepatic artery, RHA) was seen in 121 patients, 7 patients had an accessory and 114 had a replaced RHA . The replaced or accessory right hepatic artery originated anywhere from SMA, celiac trunk, aorta, CHA or gastroduodenal artery (GDA). Type 4 variation (unsual origin of both RHA and LHA) was seen in 73 patients. Type 5 variation (CHA arising from SMA) was seen in 23 patients. Type 6 variation (CHA arising directly from aorta) was seen in four patients.
Arterial variations are common in our population of patients. A detailed understanding and knowledge of these variations is necessary for surgeons and radiologists to avoid any inadvertent injuries during various procedures.
确定在大量因各种原因接受CT扫描的患者中进行腹部CT血管造影（CTA）时所发现的肝总动脉（CHA）不同动脉变异的频率。
观察性研究。
2016年10月至2018年9月，位于巴基斯坦拉合尔的沙卡特汗姆纪念癌症医院及研究中心外科肿瘤学与放射科。
对随机选取的1000例接受CTA的患者的检查结果进行回顾性评估。分析腹腔干和肠系膜上动脉分支的主动脉起源模式。然后研究肝动脉的解剖结构。肝动脉异常采用海特（Hiatt）方法进行分类。
共有629例男性和371例女性，中位年龄为54岁。644例患者出现1型变异（正常解剖结构）。135例患者出现2型变异（左肝动脉，LHA，异常）。在大多数病例中，左肝动脉起源于胃左动脉或肝总动脉（CHA）。1例患者的左肝动脉由肠系膜上动脉（SMA）替代。16例患者有副左肝动脉，119例有替代左肝动脉。121例患者出现3型变异（右肝动脉，RHA，异常解剖结构），7例有副右肝动脉，114例有替代右肝动脉。替代或副右肝动脉起源于肠系膜上动脉、腹腔干、主动脉、肝总动脉或胃十二指肠动脉（GDA）的任何部位。73例患者出现4型变异（右肝动脉和左肝动脉均起源异常）。23例患者出现5型变异（肝总动脉起源于肠系膜上动脉）。4例患者出现6型变异（肝总动脉直接起源于主动脉）。
在我们的患者群体中，动脉变异很常见。外科医生和放射科医生需要详细了解这些变异，以避免在各种手术过程中发生任何意外损伤。
