RESUMEN
BACKGROUND: Radial artery access for coronary angiography or percutaneous coronary intervention (PCI) reduces the risk of death, bleeding, and vascular complications and is preferred over femoral artery access, leading to a class 1 indication by clinical practice guidelines. However, alternate upper extremity access such as distal radial and ulnar access are not mentioned in the guidelines despite randomized trials. We aimed to evaluate procedural outcomes with femoral, radial, distal radial, and ulnar access sites in patients undergoing coronary angiography or PCI. METHODS: PubMed, EMBASE, and clinicaltrials.gov databases were searched for randomized clinical trials that compared at least 2 of the 4 access sites in patients undergoing PCI or angiography. Primary outcomes were major bleeding and access site hematoma. Intention-to-treat mixed treatment comparison meta-analysis was performed. RESULTS: From 47 randomized clinical trials that randomized 38â 924 patients undergoing coronary angiography or PCI, when compared with femoral access, there was a lower risk of major bleeding with radial access (odds ratio [OR], 0.46 [95% CI, 0.35-0.59]) and lower risk of access site hematoma with radial (OR, 0.34 [95% CI, 0.24-0.48]), distal radial (OR, 0.33 [95% CI, 0.20-0.56]), and ulnar (OR, 0.50 [95% CI, 0.31-0.83]) access. However, when compared with radial access, there was higher risk of hematoma with ulnar access (OR, 1.48 [95% CI, 1.03-2.14]). CONCLUSIONS: Data from randomized trials support guideline recommendation of class 1 for the preference of radial access over femoral access in patients undergoing coronary angiography or PCI. Moreover, distal radial and ulnar access can be considered as a default secondary access site before considering femoral access.

BACKGROUND: The radial artery is the standard access for coronary intervention; however, it is essential to have alternative accesses as it may be used as a conduit during coronary artery bypass grafting or for dialysis fistula. Ulnar and distal radial artery accesses have emerged as alternative accesses for traditional radial artery. AIM: To compare distal radial artery access and ulnar artery access as alternatives to traditional radial artery access regarding safety, efficacy, and success rate. METHODS: Two-hundred patients were included (100 traditional radial [TRA], 50 distal radial [DRA] and 50 ulnar). Access artery follow up ultrasound was performed up to 28 days. RESULTS: Procedural success rate was 97%, 74%, and 92% in the TRA, DRA and ulnar groups, respectively (p < 0.001). Crossover occurred in 3 patients (3%) in TRA, 13 patients (26%) in DRA and 4 cases (8%) in ulnar group (p < 0.001). The most common cause of crossover was failure of artery cannulation. Regarding cannulation time, the mean access time in seconds was 80.19 ± 25.98, 148.4 ± 29.60, 90.5 ± 21.84 in TRA, DRA and ulnar groups, respectively (p < 0.001). CONCLUSIONS: Our study concluded that these new approaches proved to be potential alternatives to traditional radial approach; however, ulnar artery access proved to be superior to distal radial artery access as regards success rate and cannulation time.

BACKGROUND: There is a lack of data regarding the baseline hemodynamic blood flow parameters of the wrist and digits. Therefore, we aimed to quantify the digital and radial artery blood flow parameters using ultrasound and assess the influence of patient characteristics on hemodynamics. METHODS: We analyzed ultrasonographic data from 25 patients (50 hands) between October 2019 and December 2021. Variables of interest included dimensions of the radial artery and index finger (IF) ulnar and radial digital arteries at the palmodigital crease and their corresponding flow parameters. We compared variables among men and women and patients with and without diabetes using Wilcoxon Rank Sum test. RESULTS: Our cohort consisted of 18 women (36 hands) and three participants with diabetes (six hands). The mean diameter of the IF radial digital artery was 7 mm, and that of the ulnar digital artery was 10 mm. The average peak systolic velocity for the radial digital artery was 21.31 cm/sec, and for the ulnar digital artery, it was 30.03 cm/sec. Comparing men and women, the only significant difference found was in the time-averaged mean velocity for the ulnar digital artery (men:5.66 cm/sec vs. women:9.68 cm/sec, P = 0.02) and volume of flow for the ulnar digital artery (men:10.87cc/min vs. women:18.58cc/min, P = 0.03). We found no differences in blood flow parameters comparing participants with and without diabetes. CONCLUSION: These data provide a baseline measurement of digital flow hemodynamics that can be used in future studies to model vascular flow after replantation.

BACKGROUND: Transradial access is an important tool for many neuroendovascular procedures. Occlusion of the radial or ulnar artery is not uncommon after transradial or transulnar access and can present a challenge for patients requiring repeat angiography. METHODS: Between March 2022 and June 2023, patients undergoing transradial or transulnar angiography who were found to have a radial artery occlusion or ulnar artery occlusion were identified. Repeat catheterization of the occluded artery was attempted using a 21-gauge single wall puncture needle and a 0.021-inch wire to traverse the occlusion and insert a 23-cm sheath into the brachial artery. RESULTS: A total of 25 patients undergoing 26 angiograms during the study period were found to have a radial artery occlusion or ulnar artery occlusion. Successful repeat catheterization of the occluded artery was achieved in 21 of 26 cases (80.7%). Outer diameter sheath size ranged from 5 Fr (0.0655 inch) to 8 Fr (0.1048 inch). No access complications were encountered. Number of prior angiograms, time since prior angiogram, and prior angiogram procedure time were associated with lower likelihood of successful access. CONCLUSIONS: Transradial or transulnar neuroangiography through an occluded radial or ulnar artery is safe and feasible by traversing the occlusion into the brachial artery with a 23-cm sheath. Repeat catheterization is most successful in patients with an arterial occlusion <6 months old. This technique is important in patients who have limited options for arterial access, avoiding access site complications inherent in transfemoral access, and in patients who specifically require radial or ulnar artery access.

Background: Vascular calcification (VC) has been observed in patients with hemodialysis, whereas few studies have investigated calcification in the upper extremity vasculature. Both ultrasound and X-ray are used to investigate the calcification of arteries in patients. However, there is a lack of data on the consistency between these two methods. The aim of this study was to investigate the occurrence of VC in the radial and ulnar arteries of hemodialysis patients and investigate the detection consistency in VC between ultrasound and X-ray. Methods: Ultrasound and X-ray examinations were performed in the radial and ulnar arteries of both the left and right upper extremities of 40 patients on hemodialysis. The calcification status of arteries was evaluated by the calcification index from ultrasound and X-ray respectively. Clinical variables of patients were collected from all the involved patients. Results: Of the 40 patients, VC was detected in 31 patients by ultrasound, while X-ray detected VC in 22 patients. Compared to ultrasound assessment, X-ray assessment was 73.21% sensitive but only 66.35% specific with a positive predictive value of 53.95% for detecting calcifications in the radial or ulnar artery. The level of agreement between ultrasound and X-ray results was fair. In addition, our data showed that more ulnar arteries had VCs than the corresponding radial arteries. Conclusion: Ultrasound is more sensitive in detecting the presence of calcified atherosclerotic lesions. Ultrasound and X-ray exhibited fair consistency. Ultrasound screening for upper extremity radial and ulnar arteries in hemodialysis patients may deserve attention to explore its clinical significance.

PURPOSE: Several reports have suggested that transverse arches between the radial and ulnar sides of dorsal hand skin supply the proximal part of the skin. The main objective of the study was to provide an anatomical and radiological description of a superficial vascular arch in the proximal third of the metacarpals of the long fingers. METHODS: We dissected 11 hands after injection with a mixture of lead and resin. A CT scan was performed before dissection. All vessels supplying the skin were individualized on the back of the hand and measured. RESULTS: A superficial perforating dorsal arch of the hand was present in all cases in this study. It was supplied by a dorsal radial perforating artery arising from the radial artery and by a dorsal ulnar perforating artery arising from the dorsal carpal arch. The distal recurrences of the intermetacarpal spaces communicated with this arch. This arch was the only source of vascularization of thess proximal third of the third space and presented a dominant ulnar side in the majority of cases. It presented numerous anatomical variations. The source vessels had mean diameters of 0.5 mm. There was an excellent radiological-anatomical correlation on CT scan. CONCLUSION: Given the constancy of this arch in the study, perforating flaps not yet described could be considered, having as pivot points the ulnar or radial origin of this arch.

BACKGROUND: There might be a beneficial effect of transient ulnar artery compression in prevention of radial artery occlusion (RAO) after trans-radial catheterization. OBJECTIVE: The objective of this study was to assess, by Duplex ultrasound, the efficacy of simultaneous ulnar and radial artery compression (SURC), in prevention of RAO, compared to conventional and patent hemostasis techniques. PATIENTS AND METHODS: Four hundred and fifty consecutive patients undergoing elective trans-radial catheterization were enrolled. Patients were randomized in 1:1:1 fashion into 3 groups; conventional hemostasis (Group A, n = 150 patients), patent hemostasis (Group B, n = 150 patients), and SURC technique (Group C, n = 150 patients). RAO was assessed by duplex ultrasound at 1-h post TR band removal (primary endpoint), and at 1-month. RESULTS: The primary endpoint, RAO 1-h post TR-band removal, was significantly lower among patients of group C as compared to those of group A and B (1.3%, 6.7%, and 7.3%, respectively -p = 0.03). This was still consistent at 1-month (0.7%, 8%, and 6%, respectively -p = 0.03). Multiple regression analyses revealed that lower radial artery diameter (RAD) after flow-mediated dilatation (FMD) independently predicted RAO at 1-h, while RAD at 1-h post-TR band removal was the only independent predictor of RAO at 1-month. Receiver operator characteristic (ROC) analysis showed that RAD at 1-h post-TR band removal at cut-off ≤1.75 mm could predict RAO at 1-month with high accuracy (AUC = 0.9, CI = 0.8-1.0, p < 0.001-86% sensitivity, and 95% specificity). CONCLUSION: A technique of SURC is associated with less incidence of early and late RAO compared to conventional hemostasis techniques.

Multiple dorsal fracture-dislocations of the carpometacarpal joints (CMCJ) occur from very high-energy trauma and are often associated with soft tissue injury or ischaemia. We report a 54-year-old male manual worker and a smoker who presented to the emergency room with history of compression of his right hand in a press machine. Radiographs showed dorsal fracture-dislocations of the scapho-trapezio-trapezoidal and third to fifth CMCJ's. Despite emergent Guyon canal and carpal tunnel release and closed reduction and pinning, skin pallor persisted in all digits. Brachial angiography revealed total occlusion of the radial and ulnar arteries and loss of the palmar arch at the level of the fracture. Heparin and Alprostadil were injected directly. On follow-up angiography three weeks later, the vessels were still occluded and collaterals provided digital circulation. Although digital sensations recovered, cold intolerance and stiffness resulted in a poor functional outcome. Level of Evidence: Level V (Therapeutic).

BACKGROUND: Radial artery is the preferred site for cannulation. Recently, the ulnar artery was chosen as an alternative in adults. AIMS: We aimed to measure the diameter and depth of the ulnar and radial arteries using ultrasound, and our secondary purpose was to evaluate their anatomical position using a near-infrared transcutaneous illumination device. METHODS: Forty-eight children (age range: 0-144 months) were assigned to the following groups: group Infant (aged <12 months), group Preschool (aged ≤12 to <72 months), and group School (aged ≥72 months). The diameter, depth, and position of the ulnar and radial arteries were compared between groups. RESULTS: There was no significant difference between the diameters of the ulnar and radial arteries. In group Infant, group Preschool, and group School, mean diameters of the ulnar artery were 1.27 ± 0.15 mm, 1.62 ± 0.27 mm, and 2.03 ± 0.28 mm, respectively, and the radial artery were 1.29 ± 0.15 mm, 1.69 ± 0.27 mm, and 2.06 ± 0.29 mm, respectively. The corresponding differences between the diameters of ulnar and radial arteries were -0.02 mm, -0.07 mm, and -0.02 mm [95% CI -0.16 mm to 0.12 mm, -0.25 mm to 0.11 mm, and -0.25 mm to 0.21 mm; p = .776, p = .411, and p = .852]. In groups Preschool and School, the ulnar artery was at the recommended depth of 2-4 mm for arterial cannulation compared with the radial artery. In the Infant, Preschool, and School age groups, the ulnar and radial arteries were at the recommended depth of 2-4 mm for arterial cannulation in 70.0%, 100.0%, 93.8%, and 80.0%, 65.0%, and 50.0% of the cases, respectively. (difference: -10.0%, 35.0%, and 43.8%, 95%; CI -43.4% to 23.4%, 14.1% to 55.9%, and 19.4% to 68.1%, respectively). CONCLUSIONS: The ulnar artery can be considered a promising alternative to the radial artery for facilitating arterial cannulation in children.

Vasculopathy of systemic sclerosis (SSc) is known to lead to severe limb ischemia and is often associated with macrovascular diseases. Revascularization of proximal macrovascular lesions that cause limb ischemia in patients with SSc has been recommended; however, it has rarely been reported for lesions below-the-elbow (BTE) involving the palmar artery. A 66-year-old female patient with SSc experienced critical hand ischemia (CHI) with gangrene of the left third finger that failed to respond to conventional pharmacological treatment. Angiography revealed total occlusion of the distal radial and ulnar arteries with a palmar artery lesion. Balloon angioplasty was performed for bilateral occlusive lesions around the wrist, which improved antegrade flow to the digital artery. Endovascular therapy may be a feasible option for BTE lesions involving palmar artery disease, presenting with CHI in SSc, when conventional conservative treatments fail.

BACKGROUND: Recently, radial artery access has gained popularity for interventional neurovascular procedures due to patient comfort and fewer complications. However, there are instances where the radial artery approach is not feasible. In such cases, trans-ulnar artery access (TUA) can offer an alternate route. There is limited data regarding neuro-interventional procedures performed via this approach. This study aims to evaluate the feasibility and safety of trans-ulnar approach for a wide range of interventional neurovascular procedures. MATERIALS AND METHODS: The data for all patients who underwent ulnar artery access for diagnostic or interventional neuroradiology procedures was retrospectively collected between September 2020 and March 2021. Patient demographics, procedural details, procedure success, and complications were recorded. RESULTS: During the study period, 23 patients underwent 24 trans-ulnar approach procedures. The mean age of patients was 50.1 ± 14.2 years. Fourteen diagnostic cerebral angiograms and ten interventional procedures were performed. All procedures were successfully completed via trans-ulnar approach without a switch to alternate access. No major access site complication was observed. CONCLUSION: Ulnar artery access is a safe and feasible option for neurovascular procedures. It can be effectively utilized for diagnostic cerebral angiography and a wide range of interventional procedures.

AIMS: To assess the safety and feasibility of ipsilateral transulnar access (TUA) after failure of radial access (TRA), with two sheaths placed in the radial and ulnar arteries (RA and UA) in the same arm. MATERIALS AND METHODS: All consecutive patients with TUA due to inability to cross from ipsilateral TRA in the period from March 2011 until September 2020 were included in the study. We examined clinical and procedure characteristics, access site bleeding and ischemic complications and failure mode of initial TRA. Patients were assessed by duplex ultrasound post-procedure (at an average of 56 ± 31 months) and followed clinically (functional and pain assessment). RESULTS: In this period, out of 51,866 patients 112 (0.2%) had a transulnar artery approach due to inability to cross from ipsilateral radial approach. Mean age of patients was 65 ± 11 years with 44% females. Cause for crossover to ipsilateral TUA was inability to cross a RA anomaly in 107 (95%) patients, mostly due to the presence of a "360°" RA loop in 88 patients. Type 3 and 4 EASY Score hematoma was present in 3 patients (2.6%). Six (5.3%) of the patients had new ipsilateral radial artery occlusion noted on duplex on follow up. There were no ulnar artery occlusions detected. There were no clinical or ischemic hand complications seen during a median 4.3 years of follow up. CONCLUSION: Ipsilateral transulnar artery access following failed radial artery access crossing is safe and successful for coronary angiography and intervention with low rates of complications.

Transradial access is a safe approach for visceral endovascular interventions, with lower complication rates compared to transfemoral access. This report describes an unusual case of ulnar artery thrombosis following splenic artery aneurysm embolization via left transradial approach, resulting in non-target digital ischemia and eventual amputation of the ring and little finger distal phalanges. Technical considerations to reduce the incidence of access complications are also reviewed, along with practice modifications undertaken at our institution following this case to improve outcomes.
