Intravascular ultrasound (IVUS) is a catheter-based procedure that allows for the internal assessment of a blood vessel. This includes evaluation of diameter, stenosis, calcification, and dissection. We present a case in which IVUS led to the discovery of a popliteal artery aneurysm in the setting of acute limb ischemia that was missed on computed tomography scan and angiogram.

Our case report titled Doppler Study of the Left Common Carotid Artery With Preocclusive Stenosis was published in the September 2022 issue of the Journal for Vascular Ultrasound (JVU). After publication, some comments and questions were raised by Joleen D. Rodriguez, MHA, RDCS, RVT regarding the bidirectional flow seen in partial steal, referring to Figures 5 and 6 in our report. Furthermore, they elaborated on their questions with the help of some examples of Doppler flow patterns associated with subclavian artery stenosis. It was also mentioned that collateral circulation can only be confirmed by contrast-enhanced examination. Ms. Rodriguez was of the opinion that if electrocardiogram (ECG) is performed with the Doppler waveform, that will add some additional valuable information. There was particular interest in Figure 5 from our case report, with the annotated version in the letter indicating systole and diastole with green and yellow colors. It was suggested that the region of the spectral waveform labeled as systole in our study would be diastole and vice versa. With regard to Figure 6 in our case report, it was believed that it probably would be depicting occult or pre-steal phenomenon. I am very thankful to Ms. Rodriguez and her team for their comments on our case report. An author is like a poet and appreciates those who are taking interest in his or her creation. First of all, the case presented in our article is not subclavian stenosis or steal syndrome, but rather focuses on a preocclusive stenosis of the left common carotid artery (CCA). It is a severe stenosis; theoretically, you can say more than 90% stenosis.1–3 With such a left CCA preocclusive stenosis, it is difficult for the left CCA to supply the left internal carotid artery (ICA) and external carotid artery (ECA) as it would in a normal individual. In the case presented, there was only trickle flow in the stenosis, as shown in Figure 1 with this letter (figure numbers from the case report are shown in the left-lower corner of the small images in Figure 1). On power Doppler, there was only a sliver of blood flow, while on spectral Doppler there was slow flow (15.5 cm/s); the velocity in the stenosis was decreased instead of increased as shown in Figures 2-4 from the case report. There was antegrade tardus-parvus flow4–6 in the left ICA (Figure 5) and retrograde flow in the left ECA (Figure 6). There was substantially low resistance flow in the left vertebral artery7 (Figure 7). The superior thyroid artery on the right side originating from the right ECA is acting as a collateral pathway8,9 in the thyroid gland (Figure 8) and carries blood to the left superior thyroid artery (right to left) and then to the left ECA. The blood flow direction in the left ECA is retrograde10,11 as shown in Figure 1 with this letter. Regarding the use of ECG, I think there is a great difference between spectral Doppler ultrasound and ECG.12 ECG is measuring the electric conductivity in the heart
我们题为《左颈总动脉闭塞前狭窄的多普勒研究》的病例报告发表在2022年9月的《血管超声杂志》（JVU）上。发表后，Joleen D.Rodriguez、MHA、RDCS和RVT就部分盗窃中的双向流动提出了一些评论和问题，参见我们报告中的图5和图6。此外，他们通过一些与锁骨下动脉狭窄相关的多普勒血流模式的例子详细阐述了他们的问题。还提到侧支循环只能通过造影检查来确认。罗德里格斯女士认为，如果心电图是用多普勒波形进行的，这将增加一些额外的有价值的信息。我们对病例报告中的图5特别感兴趣，信中的注释版本用绿色和黄色表示收缩期和舒张期。在我们的研究中，被标记为收缩期的频谱波形区域将是舒张期，反之亦然。关于我们病例报告中的图6，人们认为它可能描绘了神秘或盗窃前的现象。我非常感谢罗德里格斯女士和她的团队对我们的案件报告所作的评论。一个作家就像一个诗人，欣赏那些对他或她的创作感兴趣的人。首先，我们文章中介绍的病例不是锁骨下狭窄或偷窃综合征，而是左颈总动脉（CCA）咬合前狭窄。它是一种严重的狭窄；理论上，你可以说90%以上的狭窄。1-3对于这样的左颈总动脉咬合前狭窄，左颈总血管很难像正常人那样供应左颈内动脉（ICA）和外颈动脉（ECA）。在所示的病例中，狭窄处只有涓涓细流，如图1所示（病例报告中的数字显示在图1中小图像的左下角）。在功率多普勒上，只有少量血流，而在频谱多普勒上，血流缓慢（15.5 cm/s）；狭窄中的速度降低而不是增加，如病例报告的图2-4所示。左侧ICA有顺行性迟发性细小血流4-6（图5），左侧ECA有逆行性细小血流（图6）。左侧椎动脉阻力流明显较低7（图7）。源自右侧ECA的右侧甲状腺上动脉充当甲状腺中的侧支通路8，9（图8），将血液输送至左侧甲状腺上动脉（从右到左），然后输送至左侧ECA。左侧ECA的血流方向为逆行10，11，如图1所示。关于心电图的使用，我认为频谱多普勒超声和心电图之间有很大的区别。12心电图是测量心脏的电导率，而频谱多普勒描绘的是血流，包括其速度、阻力、搏动模式等。13，14我认为动脉狭窄与心电图之间没有关系。15在我们的实验室中，只有超声，自2013年以来，我一直在进行血管、肌肉骨骼、小部位和全身超声检查。我们认为没有必要对颅外颈动脉检查进行对比增强研究。就我们的病例报告而言，这是一个左侧CCA咬合前狭窄，左侧ICA由右侧ECA通过甲状腺的侧支通路提供。多普勒超声对其进行了准确诊断，随后进行了动脉内膜切除术治疗。1141953 JVUXXX10.1177/115443167221141953血管超声杂志Bacha letter 2022

A 53-year-old man with alcohol-related cirrhosis presented with acute peritonitis and esophageal variceal hemorrhage and developed septic and hemorrhagic shock and acute-on-chronic liver failure with ammonia of 497 μmol/L. He developed severe cerebral edema and convulsive status epilepticus requiring midazolam and ketamine infusions. Continuous transcranial Doppler (cTCD) monitoring of the left (not shown) and right middle cerebral arteries (MCAs) was performed at a depth of 52 mm before, during, and after treatment with 23.4% hypertonic saline (Panel 1A-D). Mean velocity (MV) and pulsatility index (PI) were graphed for both the left and right MCAs (Panel 2A and B). Monitoring with cTCD captured an initial high PI (Panels 1A and 2, Arrow 1) which initially rose while flows dropped (Panels 1B and 2, Arrow 2) in response to systemic hypotension. This suggested an intracranial vasodilatory response to systemic hypotension that contributed to elevated intracranial pressure and resultant higher resistance to flow. When the systemic hypotension resolved (Panels 1C and 2, Arrow 3), MV increased and PI began to drop. Approximately 15 minutes after the initiation of therapy for elevated intracranial pressure, MV and PI 1153671 JVUXXX10.1177/15443167231153671Journal for Vascular UltrasoundKleitsch et al research-article2023
