Background:Together with autoimmune-inflammation and fibrosis, microvasculopathy is a hallmark of SSc. However, also macrovascular changes may occur including peripheral proliferative vasculopathy. Whether this changes may represent a specific SSc marker with a predictive value remains a matter of debate.[1,2,3]Objectives:To study peripheral macrovascular involvement by color doppler ultrasound (CDUS) with spectral wave analysis (SWA) in a cohort of 40 SSc patients as compared to healthy controls. To further analyze any differences among the SSc population.Methods:Forty SSc patients and 36 healthy controls were examined by CDUS with SWA of both hands. Macrovascular involvement was assessed by measuring the resistivity index (RI) of distal ulnar and radial arteries. Examinations were performed with an Esaote MyLab Twice machine equipped with a linear 10-22 MHz probe. Ultrasound examination was carried out by two independent rheumatologists blinded to clinical conditions of the patients. Statistical analysis was performed by using MaxStat software.Results:The RI index resulted increased in the SSc cohort as compared with healthy controls (left ulnar RI 0.977 vs 0.715; right ulnar RI 0.996 vs 0.699; left radial RI 0.988 vs 0.706; right radial RI 0.999 vs 0.688; p<0.001). SSc patients with an increased RI in one artery were more probable to have an increased RI in the other vessels too (r 2 = 0.35; p<0.01). In addition, 8 out of 40 SSc patients presented left ulnar artery occlusion (UAO) and 7 out of 40 SSc patients presented right UAO, of which 6 presented bilateral UAO. Awaiting to enlarge the cohort for further analysis, descriptive data regarding increased RI at CDUS/SWA and clinical features, including years from onset of the disease, subtype of SSc, mRSS, history of digital ulcers, interstitial lung disease and PAH are described in Table 1.Conclusion:Peripheral macrovascular involvement was observed in SSc patients as compared with healthy controls. Further studies will determine whether this feature may have specificity for diagnosis/prognosis in SSc.References:[1]Lescoat A, Yelnik CM, Coiffier G et al.

Background. Despite the enormous benefits of radial access, this route is associated with a risk of radial artery occlusion (RAO). Objective. We compared the incidence of RAO in patients undergoing transradial coronary angiography and intervention after short versus prolonged hemostasis protocol. Also we assessed the efficacy of rescue 1-hour ipsilateral ulnar artery compression if RAO was observed after hemostasis. Material and Methods. Patients referred for elective transradial coronary procedures were eligible. After 6 F radial sheath removal, patients were randomized to short (3 hours) (n = 495) or prolonged (8 hours) (n = 503) hemostasis and a simple bandage was placed over the puncture site. After hemostasis was completed, oximetry plethysmography was used to assess the patency of the radial artery. Results. One thousand patients were randomized. Baseline characteristics were similar between both groups with average age 61.4 ± 9.4 years (71% male) and PCI performed on half of the patients. The RAO rate immediately after hemostasis was 3.2% in the short hemostasis group and 10.1% in the prolonged group ( p < 0.001 ). Rescue recanalization was successful only in the short group in 56.2% (11/19); at hospital discharge, RAO rates were 1.4% in the short group and 10.1% in the prolonged group ( p < 0.001 ). Conclusion. Shorter hemostasis was associated with significantly less RAO compared to prolonged hemostasis. Rescue radial artery recanalization was effective in > 50%, but only in the short hemostasis group.

Abstract Radial access has great advantages in terms of the frequency of complications, but it has one specific complication - radial artery occlusion (RAO). This complication often does not manifest itself in any way; however, it limits the use of access for the future interventions. Aim To compare methods of short and traditional hemostasis and to identify the main predictors of RAO after radial access. Materials and methods During the period from 2012 to 2018, 2000 patients were included in the study, which consisted of two parts: prospective - 1000 patients who underwent coronary angiography and percutaneous coronary intervention (PCI) with stable coronary artery disease, and retrospective part of the study, which included 1000 patients admitted for PCI from other clinics. In a prospective study, patients were divided into two groups: after coronary angiography and PCI, respectively (n=500 in the coronary angiography group and n=500 in the PCI group), and then randomized. Hemostatic bandages in the first group of patients (n=250) were removed after 12–24 hours, in the second group (n=250) - after 4±1 hours. When the occlusion of the radial artery was detected, all patients underwent an hour-long compression of the ipsilateral ulnar artery to recanalize acute RAO. Results The frequency of RAO in the retrospective part of the study was 21.8%. The frequency of RAO in the prospective part of the study was 10.2% with a traditional time hemostasis and 1.4% with a short-time compression (P<0.001). Predictors of the RAO are illustrated in table 1. Predictors of bleeding were PCI (OR 0.12, 95% CI 0.01–0.67, P=0.05) and weight (OR 1.09, 95% CI 1.02–1.18, P=0.01). Table 1. Predictors of RAO Variables Odds ratio 95% Confidential interval Significance, P Traditional-time hemostasis 8.78 4.2–21.5 <0.001 Diabetes mellitus+smoking 18.1 12.7–26.7 <0.001 Diabetes mellitus 0.45 0.25–0.83 0.009 Body mass index 0.95 0.91–0.99 0.02 Male 1.75 1.01–3.18 0.05 Protein C 0,86 0,75–0,96 0,01 Conclusion Careful examination of the patient for detecting RAO before and after interventions is essential. Short hemostasis with compression of the ipsilateral ulnar artery reduce the frequency of RAO. For short-time hemostasis, special attention should be paid to patients after PCI and with low BMI, as far as these factors are associated with a greater risk of bleeding after removal of the compression bandage.

BackgroundRadial access has become popular among neurointerventionalists because it has favorable risk profiles compared with femoral access. Difficulties in accessing or navigating the radial artery have been viewed as a reason to convert to femoral access, but ulnar artery access may prevent complications associated with transfemoral procedures.ObjectiveTo evaluate the safety and feasibility of ulnar access for neurointerventions and diagnostic neuroangiographic procedures.MethodsConsecutive patients who underwent diagnostic angiography or neurointerventional procedures via ulnar access between July 1, 2019 and April 15, 2020 were included. Data recorded were demographics, procedure indication, devices, technique, and complications. Descriptive analysis was performed.ResultsUlnar artery access was obtained for 21 procedures in 18 patients (mean age 70.3±7.8 years; nine men). Procedures included 13 diagnostic angiograms and eight neurointerventions (3 left middle meningeal artery embolization, 1 of which was aborted; 2 carotid artery stenting; 2 angioplasty; 1 mechanical thrombectomy for in-stent thrombosis). A right-sided approach with ultrasound guidance was used for all cases except one. Indications included small caliber radial artery (n=9), radial artery occlusion (n=10), and radial artery preservation for potential bypass (n=2). A 5-French slender sheath was used for diagnostic angiography; a 6-French slender sheath was used for neurointerventions. No case required conversion to femoral access. Two patients had minor hematomas after the procedure; one other had ulnar artery occlusion on 30-day ultrasonography.ConclusionUlnar access is safe and feasible for diagnostic and interventional neuroangiographic procedures. It provides a useful alternative to radial access, potentially avoiding complications associated with femoral access.

Gold Standard Technique

The superficial location of the radial artery access site eliminates the need for overly specialized closure devices. Manual compression is considered the gold standard technique. Closure devices in their many iterations are designed to work by applying continuous pressure using an adjustable balloon. They are arguably superior to manual compression as they exert a continuous and gentle pressure on the artery. The simplest, and cheapest devices might be the best ones. A good closure technique ensures compression with a “just needed” intensity to maintain anterograde flow. A good technique also incorporates the principle of patent hemostasis with or without prophylactic ulnar artery occlusion while keeping the whole process relatively simple. These techniques result in fewer radial artery occlusions and other complications. Lower complications ensure patency of the radial artery for future procedures.
