“…If the puncture position is determined only by the inguinal skin crease or palpation, the position may be inappropriate (often too low). Confirm the puncture site with fluoroscopy (femoral head) or ultrasound (bifurcation) guidance to avoid misplacement [18,29,35,36].…”

Arterial access is essential in resuscitation of trauma and hemorrhagic shock patients and can be effectively used for rapid endovascular treatment such as resuscitative endovascular balloon occlusion of the aorta (REBOA) and interventional radiology (IVR), continuous invasive hemodynamic monitoring, and frequent blood tests. In the REBOA procedure, obtaining an arterial access is the first and most critical step. Arterial access can be obtained in three ways: i) blind/landmark technique, ii) ultrasound-guided technique, or iii) surgical cutdown technique. Regardless of which technique is chosen, it is crucial to recognize external landmarks before implementing any technique.

“…Systematic biopsy is the standard procedure for the diagnosis of PCa and represents the sampling of the posterior area of the prostate, where PCa most frequently develops. The main drawback of this procedure is that the ultrasound (US) guidance fails to identify PCa, thus the biopsy is performed in a blind manner according to a preestablished scheme (12). The advent of prostate magnetic resonance imaging (MRI) lead to a change in the diagnosis of PCa, allowing for the first time to identify lesions potentially harboring malignant disease (13).…”

Atypical small acinar proliferation (ASAP) and high grade intraepithelial neoplasia (HGPIN) patterns identified at prostate biopsy yield an important clinical significance, their presence signaling an increased likelihood of future oncological development or underdiagnosed PCa. MRI and MRI-TRUS fusion prostate biopsy have recently become the standard for the diagnosis of prostate cancer. Thus, we aimed to assess the role of ASAP/HGPIN pattern in the context of these recent developments as compared with the standard systematic biopsy. The present study included 400 patients who underwent MRI-TRUS fusion prostate biopsy. A subgroup of these patients had a history of prior systematic biopsy and their results were also included in the analysis. We observed that ASAP/HGPIN pattern diagnosed at systematic biopsy is suggestive of a high-volume clinically-significant disease, most probably located outside the standard sampling area. On the contrary, ASAP/HGPIN at MRI-TRUS fusion biopsy has clinical features more similar to benign prostate hyperplasia, thus suggesting a more incipient disease, if present. No relation between concurrent ASAP/HGPIN and PCa was observed in our study.

“…Visualization of the common carotid, internal carotid, external carotid and of the vertebral arteries was attempted in both sagittal and transverse plans. Measurements were performed with the ultrasound beam intersecting the flow stream as close to an angle of 60 degrees as possible [9]. Our technologists, at their discretion, took measures to minimize aliasing by either shifting the frequency baseline in a given direction or by activating a higher duplex PRF mode [10].…”

Purpose: Duplex scanning is a useful noninvasive screening tool for the detection of carotid bifurcation disease. Internal carotid artery (ICA) peak systolic velocity (PSV) and ICA/common carotid artery (CCA) PSV ratios are proven metrics determining 70%-99% ICA stenosis. A potential disadvantage of using dramatically increasing systolic velocity measurements in areas of critical arterial stenosis is flow aliasing. Diastolic velocity should be less influenced by this flow artifact. We evaluate ICA and CCA end diastolic velocity (EDV) metrics in predicting severe ICA stenosis and document the prevalence of an aliasing artifact in a population of patients with critical ICA stenosis. Methods: Consecutive patients undergoing carotid duplex assessments and contrast angiography were compared (n = 140). ICA and CCA PSV and EDV were recorded as was evidence of the flow aliasing of ICA waveforms. ICA/CCA PSV and EDV ratios were calculated. Duplex parameters were compared with angiographic ICA measurements. Receiver-operator characteristic curve (ROC) analysis was used to determine optimal criteria to identify ICA stenosis of 70% to 99%. Results: Of 256 carotid bifurcation duplex studies, critical angiographic stenosis was present in 105 arteries. Only four completed arterial duplex scans demonstrated flow aliasing. In three of these patients, systolic metrics were non-diagnostic versus ICA/CCA EDV ratios. An ICA/CCA EDV ratio of 2.3 provided the best combination of sensitivity 73.8% and specificity 75.18%. Conclusion: ICA/CCA diastolic ratios reliably determine 70% or greater ICA stenosis. Flow aliasing infrequently complicates ICA PSV.
