RESUMEN
BACKGROUND The transradial approach (TRA) for cerebral angiography and neurointerventional treatment has gained popularity, but the narrow diameter and weak pulsation of the radial artery lower the initial puncture success rate compared to femoral artery puncture. This retrospective study from a single center evaluated the incidence of and factors associated with radial artery occlusion (RAO) in 543 patients who underwent transradial approach (TRA) for cerebral angiography. MATERIAL AND METHODS We included 543 patients who underwent TRA from July 2021 to February 2024. Ultrasound was used to determine whether the radial artery was occluded. Relevant clinical data were recorded to assess the incidence of and factors affecting RAO. RESULTS At 24 h after DSA, we performed ultrasound imaging. The patients were divided into an RAO group (n=32) and a non-RAO group (n=511). Results showed that RAO was significantly higher in patients who did not have add heparin to the antispasmodic agents, and they were more likely to have needed more than 3 radial artery puncture attempts, and tended to have received an 11-cm radial artery sheath with the Cordis puncture needles (all P<0.05). Multiple regression logistic analysis showed that adding heparin to the antispasmodic agents (OR=0.076, 95% CI: 0.018-0.321, P<0.001), having fewer than 3 radial artery puncture attempts (OR=0.245, 95% CI: 0.111-0.541, P<0.001), using a 16-cm radial artery sheath (OR=0.195, 95% CI: 0.067-0.564, P=0.003), and using Terumo puncture needles (OR=0.325, 95% CI: 0.148-0.717, P=0.005) can reduce the incidence of radial artery occlusion. CONCLUSIONS Our center found that adding heparin to the antispasmodic agents reduced the number of radial artery punctures attempts, and using a 16-cm radial artery sheath significantly lowered the incidence of early RAO after transradial cerebral angiography.

Aim: Radial artery occlusion (RAO) is a major complication of catheterization via transradial access (TRA). Our aim is to reveal the ability of high-sensitive C-reactive protein (hs-CRP) and complete blood count (CBC) components, which are inflammation markers, to predict RAO. Methods: Patients were divided into two groups: 103 with RAO and 300 without RAO. The relationship between CRP, CBC components and RAO was evaluated. Results: A significant increase in hs-CRP, monocyte, platelet (PLT), platelet distribution width (PDW) and plateletcrit values was observed after TRA, and only the increase in PDW, PLT and hs-CRP was found to be independent determinants in regression analysis. Conclusion: High PDW and PLT and increased hs-CRP levels are new independent determinants of the development of RAO.
The role of inflammation markers in occurrence of radial artery occlusion that restricts the transradial cardiac catheterization.

BACKGROUND: Reactivation of the varicella zoster virus (VZV) results in herpes zoster (HZ), which is a painful unilateral rash with a typical dermatomal distribution. HZ may be followed by postherpetic neuralgia (PHN), vasculopathy, myelopathy, retinal necrosis, and cerebellitis. Vasculopathy can cause ischemic stroke, aneurysms, arterial dissection, transient ischemic attack, and rarely, peripheral arterial disease (PAD). The possible mechanism is that the VZV travels to the arteries through the sensory ganglia, leading to inflammation and pathological vascular remodeling, which result in vasculopathy. CASE DESCRIPTION: Here, we describe a rare case of femoral artery occlusion induced vasculopathy 5 years after HZ. A 65-year-old woman visited our pain clinic with persistent pain following HZ that occurred 3 months earlier. She had several rash scars on the right thigh along with a continuous throbbing, shooting, and sharp pain. The patient was diagnosed with PHN and prescribed with medications that relieved the leg pain. The symptoms remained stationary for almost 5 years. She presented again with complaints of a paroxysmal tingling sensation in the right thigh and claudication due to increased pain, which had begun 6 months prior. She reported leg pain after walking for 10 minutes. Lumbar spine magnetic resonance imaging (MRI) revealed foraminal stenosis at the level of right L2, with no abnormality below L2. Subsequently, the patient was evaluated for vascular diseases. Lower extremity ultrasonography and computed tomography (CT) angiography revealed stenosis and thrombotic occlusions in the right superficial femoral and tibial arteries as well as the left middle femoral and tibial arteries. Surgical revascularization via percutaneous angioplasty was performed bilaterally. The leg pain was relieved after the procedure and the claudication improved. CONCLUSIONS: Peripheral artery occlusion is a rare phenomenon following HZ. In cases involving changes in HZ symptoms, further evaluation is required for potential vasculopathy.

INTRODUCTION: Acute aortic occlusion (AAO) is a rare but serious condition associated with significant morbidity and mortality. OBJECTIVE: This review provides an emergency medicine focused evaluation of AAO, including presentation, assessment, and emergency department (ED) management based on current evidence. DISCUSSION: AAO refers to obstruction of blood flow through the aorta due to either thrombosis or embolism. This condition primarily affects older adults ages 60-70 with cardiovascular comorbidities and most commonly presents with signs and symptoms of acute limb ischemia, though the gastrointestinal tract, kidneys, and spinal cord may be affected. The first line imaging modality includes computed tomography angiography of the chest, abdomen, and pelvis. ED resuscitative management consists of avoiding extremes of blood pressure or heart rate, maintaining normal oxygen saturation and euvolemic status, anticoagulation with heparin, and pain control. Emergent consultation with the vascular surgery specialist is recommended to establish a plan for restoration of perfusion to ischemic tissues via endovascular or open techniques. High rates of baseline comorbidities present in the affected population as well as ischemic and reperfusion injuries place AAO patients at high risk for complications in an immediate and delayed fashion after surgical management. CONCLUSIONS: An understanding of AAO can assist emergency clinicians in diagnosing and managing this rare but devastating disease.

The purpose of this study was to propose an innovative intraoperative criterion in a liver transplantation setting that would judge arterial flow abnormality that may lead to early hepatic arterial occlusion, that is, thrombosis or stenosis, when left untreated and to carry out reanastomosis. After liver graft implantation, and after ensuring that there is no abnormality on the Doppler ultrasound (qualitative and quantitative assessment), we intraoperatively injected indocyanine green dye (0.01 mg/Kg), and we quantified the fluorescence signal at the graft pedicle using ImageJ software. From the obtained images of 89 adult patients transplanted in our center between September 2017 and April 2019, we constructed fluorescence intensity curves of the hepatic arterial signal and examined their relationship with the occurrence of early hepatic arterial occlusion (thrombosis or stenosis). Early hepatic arterial occlusion occurred in 7 patients (7.8%), including 3 thrombosis and 4 stenosis. Among various parameters of the flow intensity curve analyzed, the ratio of peak to plateau fluorescence intensity and the jagged wave pattern at the plateau phase were closely associated with this dreaded event. By combining the ratio of peak to plateau at 0.275 and a jagged wave, we best predicted the occurrence of early hepatic arterial occlusion and thrombosis, with sensitivity/specificity of 0.86/0.98 and 1.00/0.94, respectively. Through a simple composite parameter, the indocyanine green fluorescence imaging system is an additional and promising intraoperative modality for identifying recipients of transplant at high risk of developing early hepatic arterial occlusion. This tool could assist the surgeon in the decision to redo the anastomosis despite normal Doppler ultrasonography.

BACKGROUND: Vascular graft infection is a very complex disease. Although complete excision of the infected grafts with extra-anatomic bypass or in situ reconstruction is a general treatment strategy, some concerns including reinfection in the new graft remain. CASE REPORT: An 88 year-old man presented to the hospital with abdominal swelling and bleeding. The patient had undergone revascularization for aorto-iliac occlusive disease twice in the past. The first procedure had been performed 15 years previously, with right ilio-femoral bypass grafting for right iliac artery occlusion and stent implantation for left iliac artery stenosis. The second procedure had been performed 10 years previously, with aorta-to-left femoral and left-to-right femoro-femoral bypass grafting because the terminal aorta, the first ilio-femoral bypass graft, and the stent of the left iliac artery had been occluded. The patient was diagnosed with vascular graft infection, and endovascular therapy was selected as the revascularization method prior to graft excision. It was successfully performed using various devices and techniques, followed by graft excision without critical limb ischemia. CONCLUSION: This case demonstrates that endovascular therapy prior to graft excision can be an alternative revascularization method for vascular graft infection after bypass surgery for aorto-iliac occlusive disease.

OBJECTIVES: Patent hemostasis (PH) is essential for preventing radial artery occlusion (RAO) after trans-radial procedures; however, it remains unclear how it should be obtained. The aim of this multicenter randomized study was to evaluate whether the use of an adjustable device (AD), inflated with a pre-determined amount of air (AoA), was more effective than a non-adjustable device (non-AD) for achieving PH, thereby reducing the incidence of RAO. METHODS: We enrolled a total of 480 patients undergoing transradial procedure at 3 Italian institutions. Before the procedure, a modified Reverse Barbeau Test (mRBT) was performed in all patients to evaluate the AoA to be eventually inflated in the AD. After the procedure, patients were randomized into 2 groups: (1) AD Group, using TR-Band (Terumo) inflated with the pre-determined AoA; and 2) non-AD Group, using RadiStop (Abbott). An RBT was performed during compression to demonstrate the achievement of PH, as well as 24 hours later to evaluate the occurrence of RAO. RESULTS: PH was more often obtained in the AD Group compared with the non-AD Group (90% vs 64%, respectively, P less than .001), with no difference in terms of bleedings. RAO occurred more often in the non-AD Group compared with the AD Group (10% vs 3%, respectively, P less than .001). Of note, mRBT was effective at guiding AD inflation and identifying high-risk patients in whom PH was more difficult to obtain. CONCLUSIONS: The use of AD, filled with a predetermined AoA, allowed PH significantly more often compared with non-AD, providing a significantly reduced incidence of RAO.

Determining the optimal transportation for each stroke patient is critically important to achieve the best possible outcomes. In border regions the next comprehensive stroke center may be just across an international border, but bureaucratic and financial hurdles may prevent a simple transfer to the next stroke center. We hypothesized that in regions close to international borders, patients may benefit from an "open border, closed transfer scenario", meaning that patients in whom a large vessel occlusion (LVO) is detected in the primary stroke center will benefit from a transfer to the nearest stroke center offering endovascular thrombectomy-even if this may be across a national border. We used the Swiss-German-French trinational region as an example for a region with several international borders within close proximity to one another, and compared two feasible scenarios; (a) a "closed borders, open transfer" scenario, where the patient is transported to any center in the same country, (b) an "open border, closed transfer" scenario, where patients are always transported to the nearby primary stroke center first and then to the nearest comprehensive stroke center in either the same or a neighboring country and (c) and "open borders, open transfer" scenario. The outcome of interest was the predicted probability of acute ischemic stroke patients to achieve a good outcome using a conditional probability model which predicts the likelihood of excellent outcome (modified Rankin scale score of 0-1â¯at 90 days post-stroke) for patients with suspected LVO. Results were modeled in a virtual map from which the ideal transport concept emerged. For an exemplary LVO stroke patient in Germany, the probability of a good outcome was higher in an open border, closed transfer scenario than with closed borders, open transfer (33.1 vs. 30.1%). Moreover, time to EVT would decrease from 232 min in the first scenario to 169 min in an open border, closed transfer scenario. The catchment area of the University Hospital Basel was almost double the size in an open border, closed transfer scenario compared to closed borders (1674 km2 vs. 2897 km2) and would receive transfers from 3 primary stroke centers in other countries (2 in Germany and 1 in France). Stroke patients showed a higher likelihood of good outcome in the "open border" scenarios without transfer restrictions to a specific healthcare system. This probably has implications for stroke treatment in all border regions where EVT eligible stroke patients may benefit from transport to the closest EVT capable center whenever possible, regardless of whether this hospital is located in the same or a neighboring country/jurisdiction.

Transradial access has become the most commonly used method for cardiac catheterization. Many medical and technical applications have been proposed to reduce TRA complications. The aim of this study is to examine the effect of hand dominance on radial artery spasm and radial artery occlusionin subjects undergoing CC via TRA. Between April 2020 and August 2022, 1713 subjects who underwent CC via TRA were included in the study. Patient data were obtained in terms of hand dominance of the catheterized side and RAS and RAO during a 1-month follow-up period. RAS was seen in 9.6% of the subjects. The RAS in patients catheterized by the dominant hand was significantly higher than that performed by the non-dominant hand (12 vs 7.8%; P = .004). RAO was seen in 1% of the subjects. RAO was significantly higher in the spasm side than in the no-spasm side (3 vs .8%; P = .009). Hand dominance was determined as an independent predictor of radial artery spasm (P = .006). In our study, RAS and RAO were more common on the dominant hand side than on the non-dominant side. Choosing the non-dominant hand for TRA for CC may reduce the incidence of RAS and RAO.

OBJECTIVE: Acute limb ischemia (ALI) is associated with high rates of amputation and consequent morbidity and mortality. The objective of this study is to report on the safety and efficacy of aspiration thrombectomy using the Indigo Aspiration System in patients with lower extremity (LE) ALI. METHODS: The STRIDE study was an international, multicenter, prospective, study that enrolled 119 participants presenting with LE-ALI. Patients were treated firstline with mechanical thrombectomy using the Indigo Aspiration System, before stenting or angioplasty, or other therapies as determined by treating physician. The primary end point was target limb salvage at 30 days after the procedure. Secondary end points within 30 days included technical success, defined as core laboratory-adjudicated Thrombolysis in Myocardial Infarction (TIMI) 2/3 flow rate immediately after the procedure, changes in modified Society for Vascular Surgery runoff score, improvement of Rutherford classification compared with before the procedure, patency, rate of device-related serious adverse events, and major periprocedural bleeding. Secondary end points that will be evaluated at 12 months include target limb salvage and mortality. RESULTS: Of the 119 participants enrolled at 16 sites, the mean age was 66.3 years (46.2% female). At baseline (n = 119), ischemic severity was classified as Rutherford I in 10.9%, Rutherford IIa in 54.6%, and Rutherford IIb in 34.5%. The mean target thrombus length was 125.7 ± 124.7 mm. Before the procedure, 93.0% (of patients 107/115) had no flow (TIMI 0) through the target lesion. The target limb salvage rate at 30 days was 98.2% (109/111). The rate of periprocedural major bleed was 4.2% (5/119) and device-related serious adverse events was 0.8% (1/119). Restoration of flow (TIMI 2/3) was achieved in 96.3% of patients (105/109) immediately after the procedure. The median improvement in the modified Society for Vascular Surgery runoff score (before vs after the procedure) was 6.0 (interquartile range, 0.0-11.0). Rutherford classifications also improved after discharge in 86.5% of patients (83/96), as compared with preprocedural scores. Patency at 30 days was achieved in 89.4% of patients (101/113). CONCLUSIONS: In the STRIDE (A Study of Patients with Lower Extremity Acute Limb Ischemia to Remove Thrombus with the Indigo Aspiration System) study, aspiration thrombectomy with the Indigo System provided a safe and effective endovascular treatment for patients with LE-ALI, resulting in a high rate (98.2%) of successful limb salvage at 30 days, with few periprocedural complications.

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.

STUDY'S GOAL: Our goal is to enrich the medical literature by sharing our experience in managing a case of sub-acute upper limb ischemia that revealed Horton's disease. This is particularly relevant given the current lack of well-established guidelines. INTRODUCTION: Acute upper limb ischemia is rarely seen in Horton's disease. CASE REPORT: We present a case of a 63-year-old female patient with sub-acute ischemia in both upper limbs, accompanied by jaw claudication and absence of bilateral temporal pulses. The CT Angiography scan revealed bilateral occlusions and stenosis of the axillary and sub-clavier arteries, as well as involvement of the external carotid arteries and its branches. The Arteriography confirmed abnormalities in the medium-sized arteries of the supra-aortic trunks. The histopathology examination of the temporal artery biopsy was negative. The patient received emergency corticosteroid therapy followed by an immunosuppressant. Due to the improved clinical condition of the upper limbs, surgical intervention was not performed.

The present study investigated the relationship between pre-procedural radial intima-media thickness (rIMT) and radial artery thrombosis (RAO) in patients undergoing angiography using a transradial approach (TRA). Patients (n = 90) who underwent cerebral or peripheral arterial angiography using TRA were included in the study. Ultrasonographic evaluation was performed before and 12 h after the procedure. Preoperative rIMT measurement was performed at the distal radial artery. Presence of radial artery occlusion was evaluated by ultrasonography after radial catheterization and revealed occlusive thrombus in the radial artery in 13 patients. rIMT was found to be statistically significantly higher in patients with thrombus (P < .05). When it was evaluated whether there was a correlation between age and rIMT, a positive significant correlation was found (P < .01). Our study suggests that increase of rIMT may be a risk factor for RAO in the intervention area. Before the procedure, ultrasound (US) assessment of the radial artery may be useful in determining the risk of occlusion. Thus, RAO-related technical risk factors (procedure time, number of punctures, sheath thickness, etc.) can be managed more carefully in patients having radial angiography.

BACKGROUND: Preliminary studies show that patients with large vessel occlusion (LVO) acute ischemic strokes have worse outcomes with concurrent COVID-19 infection. We investigated the outcomes for patients with LVO strokes undergoing mechanical thrombectomy (MT) with concurrent COVID-19 infection. METHODS: The National Inpatient Database (NIS) was used for our analysis. Patients in the year 2020 with an ICD-10 diagnosis code for acute ischemic stroke and procedural code for MT were included with and without COVID-19. Odds ratios (OR) were calculated using a logistic regression model with age, sex, stroke location, Elixhauser comorbidity score, and other patient variables deemed clinically relevant as covariates. RESULTS: Patients in the COVID-19 group were younger (64.3±14.4 vs 69.4±14.5 years, P<0.001), had a higher rate of inpatient mortality (22.4% vs 10.1%, P<0.001), and a longer length of stay (10 vs 6 days, P<0.001). Patients with COVID-19 had higher odds of death (OR 2.78, 95% CI 2.11 to 3.65) and lower odds of a routine discharge (OR 0.65, 95% CI 0.48 to 0.89). There was no difference in the odds of subsequent stroke and cerebral hemorrhage, but patients with COVID-19 had statistically significantly higher odds of respiratory failure, pulmonary embolism, deep vein thrombosis, myocardial infarction, acute kidney injury, and sepsis. CONCLUSIONS: Patients with LVOs undergoing MT within the 2020 NIS database had worse outcomes when co-diagnosed with COVID-19, likely due to non-neurological manifestations of COVID-19.

OBJECTIVE: We investigated the relationship between using a rotary compression device (RCD) with or without sterile gauze and adverse events in transradial access (TRA) for coronary intervention. METHODS: In this study involving 933 patients at Yueyang Hospital, we recorded TRA-related adverse events, such as bleeding, forearm hematoma, swollen palms, radial artery occlusion (RAO) and others. Logistic regression was applied to assess the association. RESULTS: Of the 933 patients (66.7% males, average age 67.8 years), 511 used RCD with sterile gauze, whereas 422 used RCD without sterile gauze. The most common adverse events were radial artery hemorrhage (7.4%), hand swelling (4.8%) and RAO (4.6%). Logistic regression analysis revealed that the use of RCD with sterile gauze was associated with a higher prevalence of adverse events [odds ratio (OR), 1.74; 95% confidence interval (CI), 1.22-2.49), even with the adjustment of potential confounders (OR, 1.71; 95% CI, 1.19-2.45). Moreover, patients who used RCD with sterile gauze exhibited an increased risk of radial artery hemorrhage (OR, 1.83; 95% CI, 1.07-3.12), swelling of the hand (OR, 1.96; 95% CI, 1.02-3.75) and RAO (OR, 3.17; 95% CI, 1.49-6.72). CONCLUSIONS: The use of RCD with sterile gauze in TRA is associated with a higher incidence of adverse events.

INTRODUCTION: Patent foramen ovale (PFO) is present in a significant proportion of young patients with stroke of undetermined etiology, but is not always causal. Therefore, classifications (RoPE, PASCAL) have been developed to determine the probability that PFO is the stroke cause. However, the presence of an initial arterial occlusion as a prediction factor was not studied when these classifications were built. Our aim was to evaluate the presence of arterial occlusion in young patients with stroke of undetermined etiology with/without high-risk PFO. METHODS: From a prospectively-built monocentric database, we identified patients aged≥18 to<60-years with strokes of undetermined etiology and complete etiological work-up, including transesophageal echocardiography. We divided patients in two groups: (i) with high-risk PFO [i.e. PFO with large interatrial shunt (>30 microbubbles) or associated with atrial septal aneurysm] and (ii) with low-risk/without PFO. We recorded the presence of arterial occlusion and large vessel occlusion (LVO) in the acute phase. RESULTS: We included 96 patients; 55 (57%) had high-risk PFO. Their median age was 48 (40-52) years, and 28 (29%) were women. The percentages of patients with arterial occlusion and with LVO were lower in the high-risk PFO group than in the low-risk/without PFO group: 11 (20%) versus 19 (46%) (P=0.008), and 5 (9%) versus 15 (37%) (P=0.002), respectively. There was no difference in the median RoPE score between groups (P=0.30). CONCLUSION: The presence of LVO could represent a "red flag" of PFO causality in stroke of undetermined etiology, and could be implemented in future PFO-related stroke classifications.

BACKGROUND: The correlation between hyperdense basilar artery sign (HDBAS) and outcome after acute basilar artery occlusion (ABAO) is debated. Our objective was to determine the usefulness of HDBAS in predicting the outcomes of patients with ABAO after endovascular treatment (EVT), intravenous thrombolysis (IVT), and best medical treatment (BMT). METHODS: The study participants were selected from the ATTENTION trial. The primary outcome of the study was a 90-day modified Rankin Scale (mRS) score, and the secondary outcome was the recanalization rate, any intracranial hemorrhage, and 90-day mortality. RESULTS: The study comprised 276 participants, with cohorts for EVT (n = 188), IVT (n = 82), and BMT (n = 88). In the EVT cohort, HDBAS was not associated with 90-day mRS score (adjusted odds ratio [OR], 0.87; 95% confidence interval [CI], 0.51-1.48; P = 0.6029), the recanalization after 24 hours of onset (adjusted OR, 0.76; 95% CI, 0.30-3.61; P = 0.9422), and 90-day mortality (adjusted OR, 0.77; 95% CI, 0.41-1.46; P = 0.4238). In the IVT cohort, HDBAS was not associated with a 90-day mRS score (adjusted OR, 0.69; 95% CI, 0.31-1.56; P = 0.3742), the recanalization after 24 hours of onset (adjusted OR, 2.24; 95% CI, 0.47-10.78; P = 0.3132), and 90-day mortality (adjusted OR, 0.64; 95% CI, 0.26-1.57; P = 0.3264). Similarly, in the BMT cohort, HDBAS was not associated with 90-day mRS score (adjusted OR, 1.11; 95% CI, 0.47-2.63; P = 0.8152), the recanalization after 24 hours of onset (adjusted OR, 1.27; 95% CI, 0.40-4.02; P = 0.6874), and 90-day mortality (adjusted OR, 1.17; 95% CI, 0.46-2.96; P = 0.748). CONCLUSIONS: HDBAS may not be a reliable predictor of outcomes for patients with ABAO, regardless of whether they received EVT, IVT, or BMT.
