Local complications of arterial puncture include hematoma, pseudoaneurysm and formation of arteriovenous fistula (AVF). The latter could cause ischemia of the particular extremity or can be hemodynamically significant especially in patients suffering from congestive heart failure. We report a case of femoro-femoral AVF after thin needle arterial puncture for blood drawing. The development of this iatrogenic AVF led to pulmonary edema. The patient stabilized completely after surgical closure of the AVF. The AVF was diagnosed by duplex Doppler ultrasonography and this method was also used for estimation of blood flow through the AVF. We discuss the role of ultrasound AVF diagnostics and the method of flow calculation.

Case report of reversible high pulmonary hypertension (PH) in patient with successful kidney transplantation (KT) is presented. The distinction of the case was the functioning arteriovenous fistula (AVF) with excessive blood flow during 15 years in the absence of indications for hemodialysis. Consequently, PH was complicated by serious congestive heart failure (CHF) with high cardiac output. Surgical closure of AVF resulted in complete regression of clinical, instrumental and laboratory signs and symptoms of PH and CHF within 2 weeks. The pathogenic role of excessive AVF blood flow in PH and CHF formation is a point of discussion. Surgical closure of AVF with excessive blood flow is recommended in cases of presence of symptomatic PH and CHF in patients after successful KT.

Introduction. The aim of this study was to investigate the role of duplex Doppler ultrasonography in diagnosis of deep venous thrombosis (DVT) of the lower extremities. Material and methods. During a 2-year period, 860 patients were examined by duplex Doppler sonography. Among these, 619(72%) were women and 241 (28%) men, with the age-range of 16-91; (mean 56,2) years. Siemens Versa Pro color doppler was used, with 7MHz transducers. Findings were categorized into four categories: 1. deep venous thrombosis (DVT); 2. pathology predominantly related to superficial veins without DVT; 3. pathology of superficial and deep veins; 4. normal findings. Results. 185 (21%) patients had DVT, 366 (42.5%) patients had pre?dominant pathology of superficial veins: postthrombotic syndrome, superficial thrombophlebitis and varicose veins. 128 (14.9%) patients had pathology of superficial and deep veins. Normal findings were found in 181 (21.1%) patients. Conclusions. Various vascular and nonvascular diseases may mimic deep venous thrombosis, and that is why US should be used whenever possible to avoid unnecessary anticoagulant therapy. .

Ultrasound Surveillance

Chronic hemodialysis therapy required regular entry into the patient’s blood stream with adequate flow. The use of arteriovenous fistulas and grafts is linked with lower morbidity and mortality than the use of catheters. However, these types of accesses are frequently affected by stenoses, which decrease the flow and lead to both inadequate dialysis and access thrombosis. The idea of duplex Doppler ultrasound surveillance is based on the presumption that in-time diagnosis of an asymptomatic significant stenosis and its treatment prolongs access patency. Details of performed trials are conflicting, and current guidelines do not support ultrasound surveillance. This review article summarizes the trials performed and focuses on the reasons of conflicting results. We stress the need of precise standardized criteria of significant access stenosis and the weakness of the metaanalyses performed.

Abstract Recently, we have read with great interest the article published by Ibarrola et al. (Clin. Sci. (Lond.) (2018) 132, 1471–1485), which used proteomics and immunodetection methods to show that Galectin-3 (Gal-3) down-regulated the antioxidant peroxiredoxin-4 (Prx-4) in cardiac fibroblasts. Authors concluded that ‘antioxidant activity of Prx-4 had been identified as a protein down-regulated by Gal-3. Moreover, Gal-3 induced a decrease in total antioxidant capacity which resulted in a consequent increase in peroxide levels and oxidative stress markers in cardiac fibroblasts.’ We would like to point out some results stated in the article that need further investigation and more detailed discussion to clarify certain factors involved in the protective role of Prx-4 in heart failure.
