RESUMEN
BACKGROUND: We evaluated the impact of completion intraoperative venography on clinical outcomes for axillosubclavian vein (AxSCV) thrombosis owing to venous thoracic outlet syndrome (vTOS). METHODS: We performed a retrospective, single-center review of all patients with vTOS treated with first rib resection (FRR) and intraoperative venography from 2011 to 2023. We reviewed intraoperative venographic films to classify findings and collected demographics, clinical and perioperative variables, and clinical outcomes. Primary end points were symptomatic relief and primary patency at 3 months and 1 year. Secondary end points were time free from symptoms, reintervention rate, perioperative complications, and mortality. RESULTS: Fifty-one AxSCVs (49 patients; mean age, 31.3 ± 12.6 years; 52.9% female) were treated for vTOS with FRR and external venolysis followed by completion intraoperative venography with a mean follow up of 15.5 ± 13.5 months. Before FRR, 32 underwent catheter-directed thrombolysis (62.7%). Completion intraoperative venography identified 16 patients with no stenosis (group 1, 31.3%), 17 with no stenosis after angioplasty (group 2, 33.3%), 10 with residual stenosis after angioplasty (group 3, 19.7%), and 8 with complete occlusion (group 4, 15.7%). The overall symptomatic relief was 44 of 51 (86.3%) and did not differ between venographic classifications (group 1, 14 of 16; group 2, 13 of 17; group 3, 10 of 10; and group 4, 7 of 8; log-rank test, P = .5). The overall 3-month and 1-year primary patency was 42 of 43 (97.7%) and 32 of 33 (97.0%), respectively (group 1, 16 of 16 and 9 of 9; group 2, 16 of 17 and 12 of 13; group 3, 10 of 10, 5 of 5; group 4, primary patency not obtained). There was one asymptomatic rethrombosis that resolved with anticoagulation, and three patients underwent reintervention with venous angioplasty for significant symptom recurrence an average 2.89 ± 1.7 months after FRR. CONCLUSIONS: Our single-center retrospective study demonstrates that FRR with completion intraoperative venography has excellent symptomatic relief and short- and mid-term patency despite residual venous stenosis and complete occlusion. Although completion intraoperative venographic classification did not correlate with adverse outcomes, this protocol yielded excellent results and provides important clinical data for postoperative management. Our results also support a conservative approach to AxSCV occlusion identified after FRR.

OBJECTIVE: Surgical decompression via transaxillary first rib resection (TFRR) is often performed in patients presenting with venous thoracic outlet syndrome (VTOS). We aimed to evaluate the outcomes of TFRR based on chronicity of completely occluded axillosubclavian veins in VTOS. METHODS: We performed a retrospective institutional review of all patients who underwent TFRR for VTOS and had a completely occluded axillosubclavian vein between 2003 and 2022. Patients were categorized into three groups based on the time of inciting VTOS event to TFRR acuity of their venous occlusion: <4 weeks, 4 to 12 weeks, and >12 weeks. We evaluated the association of TFRR timing with 1-year outcomes, including patency and symptomatic improvement. We used the χ2 test to compare baseline characteristics and postoperative outcomes. RESULTS: Overall, 103 patients underwent TFRR for VTOS with a completely occluded axillosubclavian vein (median age, 30.0 years; 42.7% female; 8.8% non-White), of whom 28 had occlusion at <4 weeks, 36 had occlusion at 4 to 12 weeks, and 39 had occlusion at >12 weeks. Postoperative venogram performed 2 to 3 weeks after TFRR demonstrated that 78.6% in the <4 weeks group, 72.2% in the 4- to 12-weeks group, and 61.5% in the >12 weeks group had some degree of recanalization (P = .76). Postoperative balloon angioplasty was successfully performed in 60 patients with stenosed or occluded axillosubclavian vein at the time of postoperative venogram. At the 10- to 14-month follow-up, 79.2% of the <4 weeks group, 73.3% of the 4- to 12-weeks group, and 73.3% of the >12 weeks group had patent axillosubclavian veins based on duplex ultrasound examination (P = .86). Among patients who underwent postoperative balloon angioplasty, 80.0%, 85.0% and 100% in the <4 weeks, 4- to 12-weeks, and >12 weeks groups respectively demonstrated patency at 10 to 14 months (P = .31). Symptomatic improvement was reported in 95.7% in the <4 weeks group, 96.7% in the 4- to 12-weeks group, and 93.5% in the >12 weeks group (P = .84). CONCLUSIONS: TFRR offers excellent postoperative outcomes for patients with symptomatic VTOS, even in cases of completely occluded axillosubclavian veins, regardless of the chronicity of the occlusion. By 14 months, 95.2% of patients experienced symptomatic improvement, and 75% attained venous patency.

BACKGROUND: Axillary vein puncture (AVP) is a valid alternative to Subclavan vein puncture for leads insertion in cardiac implantable electronic device implantation, that may reduce acute and delayed complications. Very few data are available about ICD recipients. A simplified AVP technique is described. METHODS: All the patients who consecutively underwent "de novo" ICD implantation, from March 2006 to December 2020 at the University of Verona, were considered. Leads insertion was routinely performed through an AVP, according to a simplified technique. Outcome and complications have been retrospectively analyzed. RESULTS: The study population consisted of 1711 consecutive patients. Out of 1711 patients, 38 (2.2%) were excluded because they were implanted with Medtronic Sprint Fidelis lead. Out of 1673 ICD implantations, 963 (57.6%) were ICD plus cardiac resynchronization therapy, 434 (25.9%) were dual-chamber defibrillators, and 276 (16.5%) were single-chamber defibrillators, for a total of 3879 implanted leads. The AVP success rate was 99.4%. Acute complications occurred in 7/1673 (0.42%) patients. Lead failure (LF) occurred in 20/1673 (1.19%) patients. Comparing the group of patients with lead failure with the group without LF, the presence of three leads inside the vein was significantly associated with LF, and the multivariate analysis confirmed three leads in place as an independent predictor of LF. CONCLUSION: AVP, according to our simplified technique, is safe, effective, has a high success rate, and a very low complication rate. The incidence of LF was exceptionally low. The advantages of AVP are maintained over time in a population of ICD recipients.

BACKGROUND: We have developed a new approach for peripherally inserted central catheter (PICC) insertion that we think has several advantages, including ease of insertion, access to a larger vein and patient comfort. METHODS: In this case series report, the first 19 cases were audited. RESULTS: All PICCs were inserted without complications; 17 on the first attempt. CONCLUSION: We conclude that the novel approach to the axillary vein for PICC insertion is feasible and appears to be safe when performed by an experienced operator.

BACKGROUND: Ultrasound-guided percutaneous axillary vein cannulation can reduce cannulation failure and mechanical complications, is as safe and effective as internal jugular vein cannulation, and is superior to subclavian vein cannulation using landmark technique. As far, reports of venovenous extracorporeal membrane oxygenation (VV-ECMO) with percutaneous axillary vein cannulation are rare. CASE PRESENTATION: A 64-year-old man presenting with dyspnea and chest tightness after aspirating sewage was admitted to the emergency department. Computed tomography (CT) showed diffuse exudation of both lungs and arterial blood gas analysis showed an oxygenation index of 86. He was diagnosed with aspiration pneumonia-induced acute respiratory distress syndrome (ARDS) and intubated for deteriorated oxygenation. Despite the combination therapy of protective mechanical ventilation and prone position, the patient's oxygenation deteriorated further, accompanied with multiple organ dysfunction syndrome, which indicated the requirement of support with VV-ECMO. However, vascular ultrasound detected multiple thrombus within bilateral internal jugular veins. As an alternative, right axillary vein was chosen as the access site of return cannula. Subsequently, femoral-axillary VV-ECMO was successfully implemented under the ultrasound guidance, and the patient's oxygenation was significantly improved. Unfortunately, the patient died of hyperkalemia-induced ventricular fibrillation after 36 h of VV-ECMO running. Despite the poor prognosis, the blood flow during ECMO run was stable, and we observed no bleeding complication, vascular injury, or venous return disorder. CONCLUSIONS: Axillary vein is a feasible alternative access site of return cannula for VV-ECMO if internal jugular vein access were unavailable.

BACKGROUND: Ultrasound-guided central venous catheterization (CVC) has become the standard of care. However, providers use a variety of approaches, encompassing the internal jugular vein (IJV), supraclavicular subclavian vein (SupraSCV), infraclavicular subclavian vein (InfraSCV), proximal axillary vein (ProxiAV), distal axillary vein (DistalAV), and femoral vein. OBJECTIVE: This review aimed to compare the first-pass success rate and arterial puncture rate for different approaches to ultrasound-guided CVC above the diaphragm. METHODS: In May 2023, Embase, MEDLINE, CENTRAL, ClinicalTrials.gov, and World Health Organization International Clinical Trials Platform were searched for randomized controlled trials (RCTs) comparing the 5 CVC approaches. The Confidence in Network Meta-Analysis tool was used to assess confidence. Thirteen RCTs (4418 participants and 13 comparisons) were included in this review. RESULTS: The SupraSCV approach likely increased the proportion of first-attempt successes compared to the other 4 approaches. The SupraSCV first-attempt success demonstrated risk ratios (RRs) > 1.21 with a lower 95% confidence interval (CI) exceeding 1. Compared to the IJV, the SupraSCV approach likely increased the first-attempt success proportion (RR 1.22; 95% confidence interval [CI] 1.06-1.40, moderate confidence), whereas the DistalAV approach reduced it (RR 0.72; 95% CI 0.59-0.87, high confidence). Artery puncture had little to no difference across all approaches (low to high confidence). CONCLUSION: Considering first-attempt success and mechanical complications, the SupraSCV may emerge as the preferred approach, while DistalAV might be the least preferable approach. Nevertheless, head-to-head studies comparing the approaches with the greatest first attempt success should be undertaken.

CASE: Arteriovenous (AV) fistula in the ipsilateral extremity for hemodialysis presents unique challenges during shoulder arthroplasty. We describe 3 cases of shoulder arthroplasty performed through a deltopectoral approach on the ipsilateral side of an AV fistula. In all cases, the cephalic vein was found to be arterialized with increased diameter and thickness. All procedures were successfully performed without injury to the arterialized cephalic vein. CONCLUSION: This report highlighted strategies to mitigate catastrophic bleeding from an arterialized cephalic vein during shoulder arthroplasty, which includes preoperative cross-matching, expeditious vascular surgery availability, meticulous surgical dissection, and careful retractor placement.

BACKGROUND: Axillary vein puncture (AVP) and cephalic vein surgical cutdown are recommended in international guidelines because of their low risk of pneumothorax and chronic lead complications. Directly visualizing and puncturing the axillary vein under ultrasound guidance reduces radiation exposure, provides direct needle visualization, and lowers periprocedural complications. Our hypothesis is that ultrasound-guided axillary access is safer and more feasible than the standard fluoroscopic technique. OBJECTIVES: The purpose of this study was to assess the efficacy and safety of ultrasound-guided axillary venous access during cardiac lead implantation for pacemakers (PMs) and implantable cardioverter-defibrillator (ICD) implantations. METHODS: Patients were randomized in a 1:1 fashion to either axillary venous access under fluoroscopic guidance or ultrasound-guided axillary venous access. The composite outcome, including pneumothorax, hemothorax, inadvertent arterial puncture, pocket hematoma, pocket infection, lead dislodgement, and death, was evaluated 30 days after implantation. RESULTS: We randomized 270 patients into 2 groups: the standard group for fluoroguided AVP (n = 134) and the experimental group for ultrasound-guided AVP (n = 136). No disparities in baseline characteristics were observed between the groups. The median age of the patients was 81 years, with women comprising 41% of the population. The majority of patients received single- and dual-chamber PMs (87% vs 88%; P = 1.00), and slightly over 10% in both groups received ICDs (13% vs 12%; P = 0.85). In total, we placed 357 leads in PMs and 48 leads in ICDs. Among these, 295 leads were inserted via axillary vein access and 110 via cephalic vein access. Notably, the subclavian vein was never used as a vascular access. The composite outcome was lower in the ultrasound group according to intention-to-treat analysis (OR: 0.55; 95% CI: 0.31-0.99; P = 0.034). The main difference within the composite outcome was the lower incidence of inadvertent axillary arterial puncture in the experimental group (17% vs 6%; P = 0.004). The ultrasound group also exhibited lower total procedural x-ray exposure (10,344 µGy × cm2 vs 7,119 µGy × cm2; P = 0.002) while achieving the same rate of success at the first attempt (61% vs 69%; P = 0.375). CONCLUSIONS: Ultrasound-guided AVP is safer than the fluoroscopy-guided approach because it achieves the same rate of acute success while maintaining low total procedural radiation exposure. Ultrasound AVP should be considered the optimal venous access method for cardiac lead implantation.

BACKGROUND: Pneumothorax is a well-recognized complication of cardiac implantable electronic device (CIED) insertion. While AP fluoroscopy alone is the most commonly imaging technique for subclavian or axillary access, caudal fluoroscopy (angle 40°) is routinely used at our institution. The caudal view provides additional separation of the first rib and clavicle and may reduce the risk of pneumothorax. We assessed outcomes at our institution of AP and caudal fluoroscopic guided pacing lead insertion. METHODS: Retrospective cohort study of consecutive patients undergoing transvenous lead insertion for pacemakers, defibrillators, and cardiac resynchronization therapy devices between 2011 and 2023. Both de novo and lead replacement/upgrade procedures were included. Data were extracted from operative, radiology, and discharge reports. All patients underwent postprocedure chest radiography. RESULTS: Three thousand two hundred fifty-two patients underwent insertion of pacing leads between February 2011 and March 2023. Mean age was 71.1 years (range 16-102) and 66.7% were male. Most (n = 2536; 78.0%) procedures used caudal guidance to obtain venous access, while 716 (22.0%) procedures used AP guidance alone. Pneumothoraxes occurred in five (0.2%) patients in the caudal group and five (0.7%) patients in the AP group (p = .03). Subclavian contrast venography was performed less frequently in the caudal group (26.2% vs. 42.7%, p < .01). CONCLUSION: Caudal fluoroscopy for axillary/subclavian access is associated with a lower rate of pneumothorax and contrast venography compared with an AP approach.

OBJECTIVES: To examine whether an ultrasound-guided infraclavicular cannulation of the axillary artery is noninferior to an ultrasound-guided cannulation of the common femoral artery for arterial catheter placement in critically ill patients. DESIGN: Prospective, investigator-initiated, noninferiority randomized controlled trial. SETTING: University-affiliated ICU in Poland. PATIENTS: Mechanically ventilated patients with indications for arterial catheter placement. INTERVENTIONS: Patients were randomly assigned into two groups. In the axillary group (A group), an ultrasound-guided infraclavicular, in-plane cannulation of the axillary artery was performed. In the femoral group (F group), an ultrasound-guided, out-of-plane cannulation of the common femoral artery was performed. MEASUREMENTS AND MAIN RESULTS: A total of 1,079 mechanically ventilated patients were screened, of whom 110 were randomized. The main outcome was the cannulation success rate. The secondary outcomes included the artery puncture success rate, the first-pass success rate, number of attempts required to puncture, and the rate of early mechanical complications. The cannulation success rate in the A group and F group was 96.4% and 96.3%, respectively. The lower limit of 95% CI for the difference in cannulation success rate was above the prespecified noninferiority margin of-7% demonstrating noninferiority of infraclavicular approach. No significant differences were found between the groups in terms of puncture success rate and the rate of early mechanical complications. CONCLUSIONS: An ultrasound-guided infraclavicular cannulation of the axillary artery is noninferior to the cannulation of the common femoral artery in terms of procedure success rate. We found no significant differences in early mechanical complications between the groups.

El linfedema (LE) es una de las secuelas más graves e incapacitantes secundarias al tratamiento en el cáncer de mama debido a las limitaciones funcionales, implicaciones estéticas y riesgo de infección que conlleva. Se estima que entre el 29 y 39% de las pacientes que se sujetan a una linfadenectomía axilar desarrollan LE, frente a entre 5 y 7% de los que casos que se realiza una biopsia selectiva de ganglio centinela. Para intentar reducir su incidencia, se ha desarrollado el mapeo axilar inverso. El objetivo de esta técnica es diferenciar las distintas vías de drenaje linfático axilar y del brazo mediante la inyección de un colorante azul en el brazo ipsilateral, para poder respetar los linfáticos que drenan la extremidad superior durante la disección linfática axilar. Otra posibilidad es usar verde de indocianina y así combinar el procedimiento de mapeo axilar inverso con el trazador dual estándar en la biopsia selectiva de ganglio centinela. Gracias a la microcirugía se han desarrollado técnicas como la anastomosis linfático-venosa para la prevención secundaria de LE, de manera que los linfáticos aferentes del brazo se pueden redirigir a ramas colaterales de la vena axilar para restaurar el flujo linfático fisiológico. Este procedimiento es más eficaz en las etapas precoces de LE. En los últimos años se está llevando a cabo la técnica LYMPHA, que consiste en anastomosar los vasos linfáticos del brazo a una rama colateral de la vena axilar en el momento de la disección ganglionar. Esta se ha demostrado útil en la prevención primaria de LE y en la reducción de complicaciones tempranas. (AU)
Lymphoedema (LE) is one of the most serious and disabling sequelae secondary to breast cancer treatment due to the functional limitations, cosmetic implications and risk of infection it entails. Twenty-nine to thirty-nine per cent of patients who undergo axillary lymphadenectomy (AL) are estimated to develop LE, compared to 5-7% in those who undergo selective sentinel lymph node biopsy (SLNB). In an attempt to reduce its incidence, Reverse Axillary Mapping (ARM) has been developed. The aim of this technique is to differentiate the different axillary and arm lymphatic drainage pathways by injecting a blue dye into the ipsilateral arm, in order to respect the lymphatics draining the upper extremity during axillary lymphatic dissection. Another possibility is to use indocyanine green and thus combine the ARM procedure with the standard dual tracer in SLNB. Thanks to microsurgery, techniques such as lymphatic-venous anastomosis (LVA) have been developed for secondary prevention of lymphoedema, so that afferent lymphatics in the arm can be redirected to collateral branches of the axillary vein to restore physiological lymphatic flow. In recent years, the LYMPHA technique, which involves anastomosing the lymphatic vessels of the arm to a collateral branch of the axillary vein at the time of lymph node dissection, has been implemented. This has been shown to be useful in the primary prevention of LE and in the reduction of early complications. (AU)

Burkitt lymphoma is derived from germinal or post-germinal center B cells and is a highly aggressive B cell non-Hodgkin lymphoma that represents <1 percent of adult non-Hodgkin lymphomas. The authors describe the case of a 63 years old Caucasian male, with history of human immunodeficiency virus infection, latent syphilis and varicella zoster infection on the left limb (L3 dermatome) who came to the emergency department with a palpable left axillary mass with three weeks evolution accompanied with vesicles 48 hours after. He reported a history of anorexia and weight loss on the past 3 months. Complete blood count was within normal range but was observed a fivefold elevation of lactate dehydrogenase and a CD4 count <200cells/microL. The histology of the adenopathic axillar conglomerate made the diagnosis of Burkitt lymphoma but, besides all efforts, the patient ended to die before starting a regimen of chemotherapy. (AU)

Abstract Objective: To compare the efficacy of blind axillary vein puncture utilizing the new surface landmarks for the subclavian method. Methods: This prospective and randomized study was performed at two cardiology medical centers in East China. Five hundred thirty-eight patients indicated to undergo left-sided pacemaker or implantable cardioverter defibrillator implantation were enrolled, 272 patients under the axillary access and 266 patients under the subclavian approach. A new superficial landmark was used for the axillary venous approach, whereas conventional landmarks were used for the subclavian venous approach. We measured lead placement time and X-ray time from vein puncture until all leads were placed in superior vena cava. Meanwhile, the rate of success of lead placement and the type and incidence of complications were compared between the two groups. Results: There were no significant differences between the two groups in baseline characteristics or number of leads implanted. There were high success rates for both strategies (98.6% [494/501] vs. 98.4% [479/487], P=0.752) and similar complication rates (14% [38/272] vs. 15% [40/266], P=0.702). Six cases in the control group developed subclavian venous crush syndrome and five had pneumothorax, while neither pneumothorax nor subclavian venous crush syndrome was observed in the experimental group. Conclusion: We have developed a new blind approach to cannulate the axillary vein, which is as effective as the subclavian access, safer than that, and also allows to get this vein without the guidance of fluoroscopy, contrast, or echography.
