Abstract

The vascular lab (VL) is instrumental in diagnosing vascular diseases such as renal artery stenosis and mesenteric ischemia or following a patient after transjugular intrahepatic portal systemic shunt (TIPS) creation. This article discusses indications, protocol, and diagnostic criteria for abdominal vascular ultrasound. The vascular lab can be used to investigate pathology in the abdomen either as a preliminary screening tool to evaluate for a pathology such as mesenteric artery stenosis in a patient with food fear and weight loss, renal artery stenosis in a patient with refractory hypertension or renal failure, or as a diagnostic tool in follow up after a patient has undergone a transjugular intrahepatic portal systemic shunt (TIPS) for portal hypertension. The technical success of duplex ultrasonography of the abdomen can be compromised by respiratory motion, obesity, and intestinal gas. Therefore, duplex scanning is performed in the fasting state particularly in elective outpatient cases. In emergent cases when pathology such as acute mesenteric ischemia is suspected evaluation with CT angiography may be best.

腹部血管评估

血管实验室(VL)有助于诊断血管疾病，如肾动脉狭窄和肠系膜缺血，或跟踪经颈静脉肝内门静脉系统分流术(TIPS)后的患者。本文讨论了腹部血管超声的适应症、方案和诊断标准。血管实验室可用于调查腹部病理，作为评估病理的初步筛查工具，如食物恐惧和体重减轻患者的肠系膜动脉狭窄，难治性高血压或肾衰竭患者的肾动脉狭窄，或作为随访的诊断工具，患者接受经颈静脉肝内门静脉系统分流术(TIPS)治疗门静脉高压。腹部双超声技术的成功可能会受到呼吸运动、肥胖和肠道气体的影响。因此，双工扫描在禁食状态下进行，特别是在选择性门诊病例中。在怀疑急性肠系膜缺血等病理的紧急病例中，CT血管造影可能是最好的评估方法。

期刊介绍： Interventional radiology is an area of clinical diagnosis and management that is highly technique-oriented. Therefore, the format of this quarterly journal, which combines the visual impact of an atlas with the currency of a journal, lends itself perfectly to presenting the topics. Each issue is guest edited by a leader in the field and is focused on a single clinical technique or problem. The presentation is enhanced by superb illustrations and descriptive narrative outlining the steps of a particular procedure. Interventional radiologists, neuroradiologists, vascular surgeons and neurosurgeons will find this a useful addition to the clinical literature.
