ABSTRACT
BACKGROUND: The reconstruction of complex wounds of the hand still has challenges in achieving aesthetic, functional and sensory recovery. We presented our experience of using the polyfoliate and chimeric radial collateral artery perforator flaps (RCAPF) to repair complex hand defects, aiming to explore the feasibility of special-form RCAPFs in hand coverage and enhance the comprehension of their respective indications. METHODS: From June 2014 to March 2021, 26 cases (19 males and 7 females, mean 44.4 years) underwent defect and sensation reconstruction of their hands with special-form RCAPFs, which manifested as multiple adjacent or irregular single wounds and composite tissue defects complicated with a degree of nerve injury. The clinical effects of the free RCAPFs were evaluated by integrating the postoperative and long-term follow-up outcomes of all cases. RESULTS: Altogether 8 polyfoliate flaps, 17 chimeric flaps and 1 polyfoliate-chimeric flap were harvested. Of them, 23 flaps survived uneventfully in one stage. Venous congestion occurred in 3 cases, two of which survived through vascular exploration and another one was finally repaired by the contralateral RCAPF. The follow-up results showed that the appearance of both the recipient and donor sites mostly recovered satisfactory. All the bone flaps properly healed. The BMRC sensory evaluation results of all skin flaps were S4 in 8 flaps, S3 in 18 flaps, and S2 in 9 flaps. CONCLUSIONS: The free RCAPFs can be designed in various forms with a reliable blood supply, contributing to reconstructing simple and multiple wounds of the hand with or without bone defects and dead space.

Background and Objectives: Silent cerebral ischemia (SCI) is defined as a condition that can be detected by biochemical markers or cranial imaging methods but does not produce clinical symptom. This study aims both to compare the frequency of SCI in PCIs performed with right transradial access and left transradial access and to evaluate the influencing factors. Materials and Methods: A prospective, single-center study included 197 patients undergoing PCI via transradial access between November 2020 and July 2022. The patients were categorized into right radial and left radial groups. Neuron-specific enolase (NSE) values were measured and recorded before and 18 h after the procedure. A post-procedure NSE level higher than 20 ng/dL was defined as SCI. Results: SCI occurred in 60 of the 197 patients. NSE elevation was observed in 37.4% (n = 37) of the right radial group and in 23.5% (n = 23) of the left radial group (p = 0.032). Patients with SCI had higher rates of smoking (p = 0.043), presence of subclavian tortuosity (p = 0.027), and HbA1c (p = 0.031). In the multivariate logistic regression analysis, the level of EF (ejection fraction) (OR: 0.958 95% CI 0.920-0.998, p = 0.039), right radial preference (OR: 2.104 95% CI 1.102-3.995 p = 0.023), and smoking (OR: 2.088 95% CI 1.105-3.944, p = 0.023) were observed as independent variables of NSE elevation. Conclusions: Our findings suggest that PCI via right radial access poses a greater risk of SCI compared to left radial access. Anatomical considerations and technical challenges associated with right radial procedures and factors such as smoking and low ejection fraction contribute to this elevated risk.

Common arterial grafts used in coronary artery bypass grafting include internal thoracic artery (ITA), radial artery (RA) and right gastroepiploic artery (RGA) grafts; of these, the ITA has the best clinical outcome. Here, by analyzing the single-cell transcriptome of different arterial grafts, we suggest optimization strategies for the RA and RGA based on the ITA as a reference. Compared with the ITA, the RA had more lipid-handling-related CD36+ endothelial cells. Vascular smooth muscle cells from the RGA were more susceptible to spasm, followed by those from the RA; comparison with the ITA suggested that potassium channel openers may counteract vasospasm. Fibroblasts from the RA and RGA highly expressed GDF10 and CREB5, respectively; both GDF10 and CREB5 are associated with extracellular matrix deposition. Cell-cell communication analysis revealed high levels of macrophage migration inhibitory factor signaling in the RA. Administration of macrophage migration inhibitory factor inhibitor to mice with partial carotid artery ligation blocked neointimal hyperplasia induced by disturbed flow. Modulation of identified targets may have protective effects on arterial grafts.

BACKGROUND: The introduction of radial-specific equipment has made transradial (TR) aortoiliac (AI) endovascular therapy (EVT) more convenient. OBJECTIVES: The authors aimed to investigate the perioperative outcomes of the TR approach in patients undergoing AI EVT for symptomatic peripheral artery disease. METHODS: The COMFORT (Contemporary Strategy for Aortoiliac Intervention) registry was a prospective, multicenter, observational study enrolling patients with symptomatic peripheral artery disease undergoing AI EVT between January 2021 and June 2023. The primary outcome was perioperative complications, whereas the secondary outcomes included core laboratory-evaluated residual stenosis >30%, time to hemostasis, time to ambulation, 30-day patency, and 30-day limb symptoms. These outcomes were compared between TR and non-TR AI EVT after propensity score matching. RESULTS: The TR approach was selected for 231 of the 947 patients (24.3%). The TR approach was chosen more in patients with a higher ankle-brachial index, chronic total occlusion, aortic lesion, bare nitinol stent implantation, and plain angioplasty, whereas it was chosen less in patients with dialysis, a history of AI EVT, chronic limb-threatening ischemia, bilateral calcification, and simultaneous infrainguinal EVT (all P < 0.05). After propensity score matching, the incidence of perioperative complications did not differ significantly between the groups (TR group: 6.0% vs non-TR group: 5.1%; P = 0.69). The proportions of residual stenosis, 30-day patency, and 30-day limb symptoms were not significantly different (all P > 0.05); however, the time to hemostasis and the time to ambulation were shorter in the TR group (both P < 0.05). CONCLUSIONS: Non-TR AI EVT and TR AI EVT using radial-specific equipment were associated with a similar risk of perioperative complications. The TR approach helps shorten the time required for hemostasis and ambulation.

BACKGROUND Vertebral artery origin stenosis (VAOS) has recently gained increased attention, with endovascular treatments like stent implantation showing high success and low complication rates, although less is known about VAOS compared to carotid artery stenosis. This study evaluated the safety and effectiveness of transradial (TRA) and transfemoral (TFA) approaches for VAOS stent placement. MATERIAL AND METHODS We recruited a total of 102 patients undergoing vertebral artery stenting in our hospital between January 2020 and November 2022. Patients were randomly assigned to undergo either radial or femoral approach for stent implantation in the vertebral artery, and the radial approach group secondary divided into 2 groups by patients' consent: ipsilateral or contralateral radial approach. The success rates of VAOS stent implantation, operation time, and postoperative hospitalization time were compared between the 3 groups. In addition, we compared the outcomes of stroke within 30 days, transient ischemic attack (TIA) within 30 days, and other indicators. RESULTS Of the 102 patients, the final success rate of stent implantation was not significantly different between the 3 groups. The time from sheath insertion to stent insertion in the ipsilateral TRA group (median time: 19 min [interquartile range (IQR): 12-24.5 min]) was significantly shorter than in the transfemoral approach (TFA) group (median time: 29 min [IQR: 21-35.5 min]) (P<0.01; 95% confidence interval (95% CI): 10 min [6-14 min]). There were no statistically significant differences between the 3 groups in terms of cerebrovascular events within 1 month, and patient satisfaction and preference favored the radial approach. CONCLUSIONS The postoperative hospitalization time and operation time associated with the ipsilateral TRA were shorter, and patient acceptance and satisfaction were higher.

RATIONALE: Timely treatment and recovery of cardiac arrest in out-of-hospital settings present significant challenges. This report describes a novel method of integrating advanced monitoring techniques such as radial artery cannulation in the treatment of an 85-year-old male patient who suffered an out-of-hospital cardiac arrest (OHCA). PATIENT CONCERNS: The patient, an 85-year-old man, experienced sudden cardiac arrest at home around 4:10â pm on November 22, 2023, characterized by immediate loss of consciousness and absence of pulse, and no response when called by name, necessitating urgent medical intervention. DIAGNOSES: The patient was diagnosed with OHCA by the emergency doctor, which was further confirmed by the absence of spontaneous circulation and respiratory failure. INTERVENTIONS: The patient was treated with manual cardiopulmonary resuscitation (CPR), ventilator-assisted ventilation, internal jugular venous catheterization, medical treatment, mechanical CPR, and supplemented by radial artery cannulation for invasive blood pressure monitoring. This technique was pivotal for real-time hemodynamic assessment. OUTCOMES: The invasive monitoring facilitated the early detection of the return of spontaneous circulation, allowing for the timely cessation of mechanical CPR. Subsequent treatment in the intensive care unit was optimized based on continuous arterial pressure readings, enhancing the stabilization of the patient's condition. LESSONS: This case underscores the significant role of radial artery cannulation for invasive blood pressure monitoring in improving clinical outcomes for patients experiencing OHCA. Integrating radial artery cannulation with other advanced monitoring techniques aids in the early detection of the return of spontaneous circulation and optimizes subsequent intensive care treatment.

Because of its superior safety profile and improved outcomes, trans-radial percutaneous coronary intervention (TRI) has become the preferred access in percutaneous coronary intervention (PCI) of native coronary disease. This study investigated the impact of TRI on in-hospital outcomes after PCI for coronary artery bypass graft vessels (GV-PCI). We analyzed patients who underwent GV-PCI in 2019-2022 from the Japanese nationwide registry. Patients were categorized into the TRI and trans-femoral PCI (TFI) groups. We assessed the association between TRI and in-hospital outcomes. The primary outcome was a composite of in-hospital death and major bleeding. In this study, 2,295 patients were analyzed.. The primary outcomes occurred in 29 patients (1.3%), including 17 deaths (0.7%). Major bleeding occurred in 12 patients (0.5%), and access site bleeding in 7 patients (0.3%). The TRI group (n = 1,521) showed lower crude rates of the primary outcome (0.9% vs 1.9%, p = 0.039), major bleeding (0.3% vs 1.0%, p = 0.027), and access site bleeding (0.1% vs 0.6%, p = 0.047) compared with the TFI group (n = 774). Univariable logistic regression demonstrated a significant association of TRI with reduced primary outcome (odd ratio [OR] 0.47, 95% confidence interval [CI] 0.22 to 0.98), major bleeding (OR 0.25, 95% CI 0.07 to 0.80), and access site bleeding (OR 0.20, 95% CI 0.03 to 0.94). In the multivariable analysis, TRI was still significantly associated with a decrease in major bleeding events (OR 0.29, 95% CI 0.07 to 0.93). In conclusion, the use of TRI was associated with a reduction in bleeding events when referenced to TFI in the context of GV-PCI.

BACKGROUND: While transradial access is favored for cardiac catheterization, the radial artery (RA) is increasingly preferred for coronary artery bypass grafting. Whether the RA is suitable for use as a graft following instrumentation for transradial access remains uncertain. METHODS: Consecutive patients from 2015 to 2019 who underwent coronary artery bypass grafting using both the left and right RAs as grafts were included. Instrumented RAs underwent careful preoperative assessment for suitability. The clinical analysis was stratified by whether patients received an instrumented RA graft (instrumented versus noninstrumented groups). Eligible patients with both instrumented and noninstrumented RAs underwent computed tomography coronary angiography to evaluate graft patency. The primary outcome was a within-patient paired analysis of graft patency comparing instrumented to noninstrumented RA grafts. RESULTS: Of the 1123 patients who underwent coronary artery bypass grafting, 294 had both the left and right RAs used as grafts and were included. There were 126 and 168 patients in the instrumented and noninstrumented groups, respectively. Baseline characteristics and perioperative outcomes were comparable. The rate of major adverse cardiac events at 2 years following coronary artery bypass grafting was 2.4% in the instrumented group and 5.4% in the noninstrumented group (hazard ratio, 0.44 [95% CI, 0.12-1.61]; P=0.19). There were 50 patients included in the graft patency analysis. At a median follow-up of 4.3 (interquartile range, 3.7-4.5) years, 40/50 (80%) instrumented and 41/50 (82%) noninstrumented grafts were patent (odds ratio, 0.86 [95% CI, 0.29-2.52]; P>0.99). No significant differences were observed in the luminal diameter or cross-sectional area of the instrumented and noninstrumented RA grafts. CONCLUSIONS: There was no evidence found in this study that RA graft patency was affected by prior transradial access, and the use of an instrumented RA was not associated with worse outcomes in the exploratory clinical analysis. Although conduits must be carefully selected, prior transradial access should not be considered an absolute contraindication to the use of the RA as a bypass graft.

BACKGROUND: Trans-radial (TRA) access has become increasingly prevalent in neurointervention. Nonetheless, mediastinal hematoma after TRA is an infrequent yet grave complication associated with a notably elevated mortality rate. While our review found no reported mediastinal hematoma cases managed conservatively within neuro-interventional literature, similar complications are documented in cardiac and vascular interventional radiology, indicating its potential occurrence across disciplines. CASE PRESENTATION: Carotid computed tomography angiography (CTA) showed calcified plaques with stenosis (Left: Severe, Right: Moderate) in the bilateral internal carotid arteries (ICAs) of an 81-year-old male presented with paroxysmal weakness in the right upper limb. Dual antiplatelet therapy with aspirin and clopidogrel was administered. On day 7, DSA of the bilateral ICAs was performed via TRA. Post-DSA, the patient experienced transient loss of consciousness, chest tightness, and other symptoms without ECG or MRI abnormalities. Hemoglobin level decreased from 110 g/L to 92 g/L. Iodinated contrast-induced laryngeal edema was suspected, and the patient was treated with intravenous methylprednisolone. Neck CT indicated a possible mediastinal hemorrhage, which chest CTA confirmed. The patient's treatment plan involved discontinuing antiplatelet medication as a precautionary measure against the potential occurrence of an ischemic stroke instead of the utilization of a covered stent graft and surgical intervention. Serial CTs revealed hematoma absorption. Discharge CT showed a reduced hematoma volume of 35 × 45 mm. CONCLUSIONS: This case underscores the need for timely identification and precise manipulation of guidewires and guide-catheters through trans-radial access. The critical components of successful neuro-interventional techniques include timely examination, rapid identification, proper therapy, and diligent monitoring.

OBJECTIVE: There is growing evidence supporting the utilization of the radial artery as a secondary arterial graft in coronary artery bypass grafting (CABG) surgery. However, debates continue over the recovery period of the radial artery following angiography. This study aims to evaluate the clinical outcomes and experiences related to the use of the radial artery post-angiography in total arterial coronary revascularization. METHODS: A retrospective analysis was performed on data from patients who underwent total arterial CABG surgery at the University of Hong Kong Shenzhen Hospital from July 1, 2020, to September 30, 2022. Preoperative assessments included ultrasound evaluations of radial artery blood flow, diameter, intimal integrity, and the Allen test. Additionally, pathological examinations of the distal radial artery and coronary artery CT angiography were conducted, along with postoperative follow-up to assess the safety and efficacy of using the radial artery in patients undergoing total arterial CABG. RESULTS: A total of 117 patients, compromising 102 males and 15 females with an average age of 60.0 ± 10.0 years, underwent total arterial CABG. The internal mammary artery was used in situ in 108 cases, while in 4 cases, it was grafted to the ascending aorta due to length limitations. Bilateral radial arteries were utilized in 88 patients, and bilateral internal mammary arteries in 4 patients. Anastomoses of the proximal radial arteries to the proximal ascending aorta included 42 cases using distal T-anastomosis and 4 using sequential grafts. The interval between bypass surgery and coronary angiography ranged from 7 to 14 days. Pathological examination revealed intact intima and continuous elastic membranes with no significant inflammatory infiltration or hyperplastic lumen stenosis in the radial arteries. There were no hospital deaths, 3 cases of perioperative cerebral infarction, 1 secondary thoracotomy for hemorrhage control, 21 instances of intra-aortic balloon pump (IABP) assistance, and 2 cases of poor wound healing that improved following debridement. CT angiography performed 2 weeks post-surgery showed no internal mammary artery occlusions, but 4 radial artery occlusions were noted. CONCLUSION: Ultrasound may be used within 2 weeks post-angiography to assess the recovery of the radial artery in some patients. Radial arteries with intact intima may be considered in conjunction with the internal mammary artery for total arterial coronary CABG. However, long-term outcomes of these grafts require further validation through larger prospective studies.

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: The aim is to evaluate the relationship between C-reactive protein (CRP) to albumin ratio (CAR) and radial artery thrombosis in patients undergoing radial angiography. Patients & methods: We prospectively included 261 consecutive patients undergoing radial angiography, assessing radial artery diameter and thrombosis presence. Results: The CRP values were significantly higher in radial artery thrombosis group compared with group without thrombosis (13.01 vs. 4.33 mg/l, p < 0.001, respectively). Also CAR was statistically significantly different between the group with thrombosis and the group without thrombosis (0.102 vs. 0.349, p < 0.001). Conclusion: Our study is the first to assess CAR in radial thrombus development post-procedure in patients undergoing radial angiography. CAR can be useful in determining radial artery thrombosis after the coronary 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.

Radial artery (RA) access has been increasingly utilized for coronary procedures because of lower rates of access-site complications and improved patient satisfaction. However, limited data are available for RA access for peripheral vascular intervention (PVI). We performed a retrospective review of 143 patients who underwent PVI through RA access from February 2020 to September 2022 at a single institution. Baseline characteristics and follow-up data were ascertained from a prospectively maintained institutional database. Of 491 PVI, 156 (31.8%) were performed through the RA. Anatomical locations for intervention were the femoral (44.8%), iliac (31.1%), popliteal (9.6%) peroneal (2.7%), tibial (9.9%), and subclavian (1.9%) arteries. Procedural access was obtained through the right RA (92.9%), left RA (4.5%), or right ulnar artery (2.6%) using the 6 French R2P Destination Slender sheath in 85, 105, and 119 cm lengths. Atherectomy was used in 34.7%. Mean contrast volume was 105.5 ml and the average fluoroscopy time was 18.5 minutes. Conversion to femoral access occurred in 3 cases (1.9%) because of arterial spasm and noncrossable lesions. Concomitant pedal access occurred in 2 cases (1.3%). Periprocedural complication rate was 3.84%, of which access-site hematoma was most common (3.2%); none required blood transfusion, surgical intervention, or additional hospital stay. There was 1 case (0.64%) of in-hospital stroke. The mortality rate at 30-day, 6-month, and 1-year was 1.4%, 2.8%, and 4.2%, respectively. In conclusion, RA access is feasible for diverse PVI, and future studies are needed to assess safety and benefit compared with femoral artery access.

AIMS: The optimal vascular access site for percutaneous coronary interventions (PCIs) in patients with acute myocardial infarction (AMI) complicated by cardiogenic shock (CS) remains uncertain. While observational data favour transradial access (TRA) due to lower complication rates and mortality, transfemoral access (TFA) PCI offers advantages such as shorter access and procedure times, along with quicker escalation to mechanical circulatory support (MCS). In this study, we aimed to investigate factors associated with a transfemoral approach and compare mortality rates between TRA and TFA in AMI-CS patients undergoing PCI. METHODS AND RESULTS: Data from a nationwide registry of AMI-CS patients undergoing PCI (2017-2021) were analysed. We compared patient demographics, procedural details, and outcomes between TRA and TFA groups. Logistic regression identified access site factors and radial-to-femoral crossover predictors. Propensity score-matched (PSM) analysis examined the impact of access site on mortality. Of the 1562 patients, 45% underwent TRA PCI, with an increasing trend over time. Transfemoral access patients were more often female, had a history of coronary artery bypass grafting, lower blood pressure, higher resuscitation and intubation rates, and elevated lactate levels. After PSM, 30-day mortality was lower in TRA (33% vs. 46%, P < 0.001). Predictors for crossover included left coronary artery interventions, multivessel PCI, and MCS initiation. CONCLUSION: Significant differences exist between TRA and TFA PCI in AMI-CS. Transfemoral access was more common in patients with worse haemodynamics and was associated with higher 30-day mortality compared with TRA. This mortality difference persisted in the PSM analysis.

BACKGROUND: Radial access is the default approach in interventional cardiology. The Axiostat® surgical hemostatic dressing, using chitosan as its active component, has demonstrated potential in accelerating blood clotting. This study aims to assess the efficacy and the safety of the Axiostat® dressing in achieving hemostasis in patients undergoing transradial coronary angioplasty (TRCA). METHODS: This prospective, single-center observational study, conducted in 2022, enrolled consecutive patients undergoing TRCA, with a target of 150 participants. The primary outcome was the success rate of radial artery hemostasis at 120 min, without bleeding necessitating immediate re-compression. The secondary outcome included Axiostat® performance at 24 h and 30 days Postprocedure. RESULTS: The study was terminated prematurely for ethical and patient safety reasons, after inclusion of 41 consecutive TRCA patients due to an unexpectedly high radial artery thrombosis rate (19.5%, n = 8/41) observed 24 h Postprocedure. The success rate of radial hemostasis with the Axiostat® dressing was 78.0%. Procedural details and patient characteristics were comparable between successful Axiostat® removal and device failure cases. CONCLUSION: The use of the Axiostat® dressing to achieve hemostasis after TRCA is effective but is associated with an unexpectedly high incidence of radial thrombosis. Our results should encourage caution in the future evaluation and use of this device for radial artery compression following TRCA.

CASE: This case report describes a patient with paresthesia in the distribution of the superficial sensory branch of the radial nerve that was treated with surgery. Intraoperatively, there was a unique cause of internal compression by a rare superficial radial artery variant running adjacent to it. The nerve was mobilized from the artery with fascial releases. The patient had symptom resolution postoperatively. CONCLUSION: To our knowledge, this cause of compression has not been described before and should be considered in a differential diagnosis. In addition, clinicians should be aware of this anatomical variant during venipunctures and surgical approaches.
