Department of Vascular Diseases, University Medical Centre Ljubljana, Zaloška c. 7, 1525, Ljubljana, Slovenia; Division of Internal Medicine, Faculty of Medicine, University of Ljubljana, Slovenia.

Atherosclerosis is a systemic disease with different faces. Despite identical or similar pathogenetic mechanisms, atherosclerotic lesions and their clinical manifestations vary in different parts of the vascular system. Peripheral arterial disease (PAD) represents one of the most frequent clinical manifestations of atherosclerosis with predominant location in the superficial femoral artery (SFA). Read More

A comparison of acute mouse hindlimb injuries between tourniquet- and femoral artery ligation-induced ischemia-reperfusion.

Injury 2021 Sep 9. Epub 2021 Sep 9.

Department of Emergency Medicine, University of Nebraska Medical Center, Omaha, NE 68198-5850, USA; Department of Cellular and Integrative Physiology, University of Nebraska Medical Center, Omaha, NE, USA. Electronic address:

The tourniquet or femoral artery ligation is widely used to stop extremity hemorrhage or create a bloodless operating field in the combat scenario and civilian setting. However, these procedures with subsequent reperfusion also induce ischemia-reperfusion (IR) injuries. To fully evaluate animal models of limb IR injuries, we compared tourniquet- and femoral artery ligation-induced IR injuries in the hindlimb of mice. Read More

Peripheral arterial response during haemodialysis - is two-dimensional speckle-tracking a useful arterial reactivity assessment tool?

J Ultrason 2021 Aug 9;21(86):e213-e218. Epub 2021 Sep 9.

Department of Internal Medicine and Transplantation Nephrology, 1st Chair of Internal Medicine, Medical University of Łódź, Poland.

2D speckle tracking is a method used in myocardial strain assessment. However, several studies have confirmed the suitability of its application in the assessment of arterial strain (a marker of arterial stiffness). The aims of our study were to evaluate whether 2D speckle tracking can assess the changes in carotid and femoral strain caused by fluid loss during haemodialysis, and to determine the direction and amount of these changes.

Effect of ultrasound-guided selective sensory nerve blockade of the knee on pain management compared with periarticular injection for patients undergoing total knee arthroplasty: A prospective randomized controlled trial.

Knee 2021 Sep 15;33:1-10. Epub 2021 Sep 15.

Department of Anesthesiology, King Chulalongkorn Memorial Hospital, The Thai Red Cross Society and Faculty of Medicine, Chulalongkorn University, Bangkok, Thailand.

Background: Ultrasound-guided selective sensory nerve blockade (SSNB) of the knee, including an adductor canal block (ACB), anterior femoral cutaneous nerve block, and infiltration between the popliteal artery and posterior capsule of the knee may provide effective motor-sparing knee analgesia for total knee arthroplasty (TKA). We hypothesized that the SSNB would manage pain better on ambulation 24 hours postoperatively compared to periarticular infiltration (PAI), when combined with postoperative continuous ACB.

Methods: Seventy-two patients undergoing elective TKA under spinal anesthesia were randomly assigned to either SSNB (SSNB group) or intraoperative PAI (PAI group). Read More

ULSOSEAL Technique: A Unique Technique to Achieve Hemostasis Using ExoSeal in High-Risk Patients after Common Femoral Artery Puncture.

J Interv Cardiol 2021 28;2021:2470333. Epub 2021 Aug 28.

Department of Cardiology, Saiseikai Yokohama City Eastern Hospital, Yokohama-Shi, Japan.

This study aimed to assess the safety and feasibility of the ULtrasound-guided uSe Of exoSEAL technique (ULSOSEAL technique) in patients at a high risk of complications following the use of ExoSeal. ExoSeal is a novel, completely extravascular hemostatic device that can treat punctures of the common femoral artery; however, it is not preferable for use in cases that require hemostasis of complex puncture sites. From November 2019 to August 2020, the ULSOSEAL technique was performed in 35 patients with implanted stents (6 patients, 17%), severe calcification (32 patients, 91%), and plaque (7 patients, 20%) around the puncture site; the presence of these conditions is usually undesirable when using ExoSeal.

Wall shear stress mapping for human femoral artery based on ultrafast ultrasound vector Doppler estimations.

Med Phys 2021 Sep 15. Epub 2021 Sep 15.

Department of Biomedical Engineering, National Cheng Kung University, Taiwan.

Purpose: Wall shear stress (WSS), a type of friction exerted on the artery wall by flowing blood, is considered a crucial factor in atherosclerotic plaque development. Currently, achieving a reliable WSS mapping of an artery noninvasively by using existing imaging modalities is still challenging. In this study, a WSS mapping based on vector Doppler flow velocity estimation was proposed to measure the dynamic WSS on the human femoral artery. Read More

CVIR Endovasc 2021 Sep 15;4(1):69. Epub 2021 Sep 15.

Department of Cardiovascular Medicine, Toho University Faculty of Medicine Graduate School of Medicine, Tokyo, Ota-ku, Japan.

Background: Currently, the success rate of EVT for treating CTO of the SFA is high; however, EVT is still found to be insufficient in treating CTOs with severely calcified lesions. Even if the guidewire crosses the lesion, the calcifications may still cause difficulties during stent expansion.

Main Text: A 78-year-old male had been reported to have intermittent claudication with chronic total occlusion (CTO) of the right superficial femoral artery (SFA). Read More

Umbilical vessel catheter retro-exchange technique (U-RET) for repeat use of the umbilical artery for neonatal vascular intervention: Technical note.

Interv Neuroradiol 2021 Sep 13:15910199211041445. Epub 2021 Sep 13.

Department of Neurosurgery, St Luke's International Hospital, Tokyo, Japan.

A high flow arteriovenous shunts in newborns may require urgent endovascular treatment right immediately after delivery if high output cardiac failure is resistant to medical treatment. The umbilical approach is often the first choice of the access route for endovascular treatment in the newborn. It is, however, not infrequent that the patient has an extensive lesion, which necessitates a second session of treatment because of the limitation of the usable amount of the contrast material in one session.

Front Mol Biosci 2021 25;8:724465. Epub 2021 Aug 25.

First Department of Cardiology, "Hippokration" General Hospital, University of Athens Medical School, Athens, Greece.

MicroRNAs have been linked to angiogenesis and could prove to be valuable future therapeutic targets in ischemic cardiovascular diseases. Ten-week-old male C57Bl/6 mice were subjected to left femoral artery ligation and were treated with microRNA-126 mimic at a dose of 5 mg/kg (Group A, = 10) or 5 mg/kg microRNA mimic negative control (Group B, = 10) on days 1, 3, and 7. Laser Doppler imaging was performed to verify successful ligation on day 0 and to evaluate differences in the ischemic-to-normal (I/N) hind limb perfusion ratio on day 28. Read More

Front Med (Lausanne) 2021 25;8:692399. Epub 2021 Aug 25.

Center for Cardiac Intensive Care, Beijing Anzhen Hospital, Capital Medical University, Beijing, China.

Limited research is available on the pattern of double distal perfusion catheters in patients on venoarterial extracorporeal membrane oxygenation (VA-ECMO) with an intra-aortic balloon pump(IABP). Here, we compared the outcomes of a double distal perfusion catheter and conventional treatment in patients who received VA-ECMO with IABP and had severe lower limb ischemia on the IABP side. We reviewed the data of 15 adult patients with postcardiotomy cardiogenic shock who received VA-ECMO via femoral cannulation combined with an IABP in the contralateral artery that was complicated with severe acute limb ischemia (ALI) on the same side as the IABP between January 2004 and December 2016.

Dental Pulp Mesenchymal Stem Cells Attenuate Limb Ischemia via Promoting Capillary Proliferation and Collateral Development in a Preclinical Model.

Stem Cells Int 2021 31;2021:5585255. Epub 2021 Aug 31.

Beijing SH Biotechnology Co. Ltd., Beijing 100070, China.

Critical limb ischemia (CLI), an end-stage manifestation of peripheral artery disease (PAD), still lacks effective therapeutic strategies. Recently, dental pulp-derived mesenchymal stem cells (DP-MSCs) have been attracting more and more attentions in therapeutic applications due to their high proliferation ability, powerful osteogenic differentiation potential, and effective anti-inflammatory effects. In this study, we compared the therapeutic effects of MSCs derived from different sources in a femoral artery-ligated preclinical ischemic model. Read More
