A clinical case of treatment of rosacea with a high-intensity laser at different stages, performed under control of high-resolution ultrasound (HRU), is presented. According to clinical guidelines, patients in the erythematous stage of rosacea (stage I) undergo selective coagulation of superficial vessels with a neodymium laser. Diagnosis and determination of the severity of the disease are carried out based on the presence of primary and secondary elements of the rash. There are no criteria for ultrasound assessment of the skin and its vascularization in patients with rosacea. During ultrasound examination after 4 laser procedures in B-mode, the dermis is heterogeneous due to hypoechoic papillary and hyperechoic reticular layers, without signs of infiltrative changes, in the color Doppler mapping mode there is a pronounced vascularization of the papillary dermis in the area of interest, represented by multiple vessels in contrast to single vascular structures seen on ultrasound after two laser treatments. According to the results of ultrasound examination, a more severe degree of the disease was diagnosed, which served as the basis for prescribing therapy with systemic retinoids. Clinical observation demonstrates the capabilities of ultrasound in planning laser procedures in order to reduce the risk of complications, their early diagnosis and monitoring of treatment if they occur.

Background:Systemic sclerosis (SSc) can lead to vascular complications such as digital ulcers or pitting scars (DU/PS). These changes develop in most patients with SSc and exacerbate their condition. However, there are no methods for dynamic assessment of the vascular involvement. The dynamics of capillaroscopic changes is very slow.Objectives:The aim of the study was to compare blood flow parameters of digital arteries in SSc patients and healthy individuals and to compare with nailfold capillaroscopy and clinical signs of ischemia (DU/PS).Methods:32 SSc patients, mean age 49,5 [42,0; 59,0] yrs and 26 ‘healthy’, mean age 43,5 [33,0; 57,0], were included. Groups of patients differed by gender and age. The exclusion criterion was the presence of obliterating vascular disease of the upper extremities. An Esaote MyLab Twice US system with 22 MHz linear probe was used. A total of SSc patients and controls underwent Color Doppler ultrasonography (CDUS) of 376 (256 + 208) digital arteries to compare blood flow velocity, resistive indices (RIs) and presence of occlusion. Nailfold capillaroscopy, clinical and laboratory data were also evaluated.Results:In digital arteries, pulsatility index (PI), peak systolic velocity (PSV) and end-diastolic velocity (EDV) were significantly lower and RI higher in SSc patients compared with controls (PSV: 13,28 [9,88; 16,7] vs17,45 [12,65; 22,5] cm/s, p=0,008; EDV: 2,68 [1,78, 4,05] vs 6,37 [4,75; 8,5] cm/s, p=0,000; RI: 0,78 [0,69; 0,81] vs 0,68 [0,59; 0,74], p=0,005; PI: 1,73 [1,32; 2,19] vs 1,22 [0,99; 1,55], p=0,002).We did not find any correlation between two methods. Also, we did not reveal any correlation between DU/PS, clinical, laboratory data and CDUS, but we found relationship between DU/PS and avascular areas or capillaroscopic findings (r= 0,37, p=0,045 and r= 0,40, p=0,03 correspondingly).Conclusion:Blood flow is significantly decreased in digital arteries in SSc, but clinical features of vasculopathy depend on microcirculatory disorders. It is important to continue research to find methods for dynamic evaluation of microcirculatory changes.References:noDisclosure of Interests:None declared

The authors present their experience in ultrasound patterns of primary and recurrent endometrioma and correspondence with histopathological results, using 2D and color Doppler ultrasound examination. Cases of primary and recurrent endometriomas, as well as other false positive diagnosis are presented. The presence of the peripheral, healthy ovarian tissue, is the principal difference between the primary endometrioma and their recurrence. The arousal of papillary projections or solid-type echostructure decreases the likelihood of an endometrioma without histological atypia. Postmenopause modifies the ultrasound features of endometrioma by decreasing homogeneity and echogenicity

There are controversies in the literature on the blood supply to the forearm after surgical removal of the radial artery in coronary artery bypass grafting (CABG). The objective was to investigate the arterial remodeling of the ulnar artery after the removal of the radial artery in myocardial revascularization by means of ultrasound examination with color Doppler in the pre- and post-operative periods. This paper describes an observational prospective study of the remodeling of the left brachial and ulnar arteries (donor arm) in 103 right-handed non-consecutive adult patients undergoing CABG with removal of the ipsilateral radial artery using the color Doppler ultrasound examination. In the ulnar artery, a significant increase (P < 0.05) was seen in the following measurements: lumen diameter by 13%, lumen area by 26%, peak systolic flow by 40%, and average flow by 46%. Intima-media thickness measured in the ulnar artery did not show a statistically significant difference (P = 0.22), except in diabetic patients (P = 0.007). We conclude that the ulnar artery undergoes positive physiological remodeling, adapting to the new requirements of chronic increase in flow after the ipsilateral removal of the radial artery to serve as a graft in CABG. There was no evidence of increased intima-media thickness, except in diabetic patients.

Sirenomelia is a rare congenital malformation characterized by varying degrees of fusion of the lower extremities. It is commonly associated with severe urogenital and gastrointestinal malformations; however, the association of sirenomelia with anencephaly and rachischisis totalis is extremely rare. To our knowledge, the prenatal sonographic images of this association have not been previously published. Here, we present prenatal sonographic images of this association, detected during the 17th week of gestation through combined two-dimensional, four-dimensional, and color Doppler ultrasound. Two-dimensional ultrasound images showed anencephaly, spina bifida, and possible fusion of the lower limbs. Three-dimensional HDlive rendering images confirmed the final diagnosis of sirenomelia with anencephaly and rachischisis totalis. The patient opted to undergo medical termination of pregnancy and delivered a fetus with fused lower limbs, anencephaly, and rachischisis totalis confirming the in utero imaging findings. Awareness of these rare associations will help avoid misdiagnoses and facilitate prenatal counselling. This case highlights the importance of a thorough ultrasound examination.

Perforator Arteries

Purpose: The second dorsal metacarpal (SDMC) perforator flap has been widely used for the soft tissue reconstruction of the hand. However, it is difficult to identify the depth and branches of the perforators of the second dorsal metacarpal artery (SDMA) using only handheld acoustic Doppler flowmetry (HADF), which is the most common method. The purpose of this study was to compare the results of examination by color Doppler ultrasonography (CDU) with those of HADF and to evaluate the efficacy of CDU for detection of the perforators to be used in the design of the SDMC flap. Methods: Twenty-two healthy volunteers (42 hands) were examined using both CDU and HADF. All locations identified as the perforators of the SDMA by the two examinations were mapped respectively. Results: The total perforator arteries detected with CDU in all hands were 111 branches, 49 branches of which could not be identified with HADF. The average number of perforators of the SDMA per hand found with CDU was 2.8 branches, while that for HADF was only 1.8 branches. The detection rates of the cutaneous perforators of the SDMA by CDU were 100% in the proximal one-third of the second metacarpal and 95% in the distal one-fourth of the second metacarpal. Conclusion: This study demonstrated the superiority of CDU compared with HADF for detection of the perforators of the SDMA. The CDU examination could easily identify the locations of the cutaneous perforators and help in the useful assessment of vascularity for the SDMC flap.

Ultrasound technology has revolutionized the practice of safer vascular access, for both venous and arterial cannulation. The ability to visualize underlying structures of the chest, neck, and upper/lower extremities provides for greater success, speed, and safety with all vascular access procedures. Ultrasound not only yields superior procedural advantages but also provides a platform to perform a thorough assessment of the vascular structures to evaluate vessel health, viability, size, and patency, including the location of other important and best avoided anatomical structures—prior to performing any procedures. Such assessment is best performed using a systematic and standardized approach, as the Rapid Central Vein Assessment, described in this study.
