A Case Report of Delayed Presentation of a Carotid-Jugular Fistula Caused by Blunt Injury from an Arrow.

BACKGROUND: Acquired arteriovenous fistulas (AVFs) are most commonly caused by direct arterial trauma, with 90% of traumatic AVFs due to penetrating trauma. Post-traumatic common carotid artery-internal jugular vein fistulae are rare, with an incidence of 4% to 7% of all traumatic AVFs. CASE REPORT: We present a case of delayed presentation of a patient with shortness of breath, neck pain, and worsening right upper extremity paresthesias 10 days after a blunt injury to the neck by an arrow. He was subsequently found to have a common carotid artery-internal jugular vein fistula and a common carotid pseudoaneurysm on computed tomography angiography. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Post-traumatic common carotid-jugular AVFs are uncommon, especially in patients with delayed presentations and a blunt injury mechanism. If left untreated, AVFs may progress to high-output cardiac failure, atrial fibrillation, and embolization. Clinicians must be aware of this finding, given the potential for significant morbidity.

Resistance exercise affects catheter-related thrombosis in rats through miR-92a-3p, oxidative stress and the MAPK/NF-κB pathway.

BACKGROUND: MiR-92a-3p and oxidative stress are associated with catheter-related thrombosis (CRT). As a kind of physical intervention, resistance exercise can effectively promote blood circulation. In this study, we investigated the roles of miR-92a-3p, oxidative stress and the P38 mitogen-activated protein kinase/nuclear factor-κB (MAPK/NF-κB) pathway in CRT during resistance exercise. METHODS: The rat CRT model was used for resistance exercise intervention. Moreover, pathological changes from the right jugular vein to the right auricle were observed under an electron microscope. In addition, reactive oxygen species (ROS) production, malondialdehyde (MDA) activity and heme oxygenase (HO-1) level in rat serum were detected via ELISA. The expression levels of miR-92A-3p and HO-1 in the vascular tissues of the rats were determined via real-time quantitative PCR. Additionally, the expression levels of HO-1, NF-κB P65, p38MAPK and IκBa in the venous tissues of the rats were analysed by Western blot analysis. RESULTS: The pathological results showed that the thrombosis incidence rate in the CRT + RE group was lower than that in the CRT group. In the CRT group, the expression levels of ROS and MDA, which are markers related to oxidative stress in serum, significantly increased whilst the expression of HO-1 decreased. In the venous tissue, the expression of miR-92a-3p increased, the level of HO-1 decreased, the levels of p38MAPK and NF-κB p65 significantly increased but that of P-IκBa and IκBa significantly decreased. In the CRT + RE group, after administering the resistance exercise intervention, ROS production and MDA activity in serum significantly decreased, the expression level of HO-1 increased and the expression level of miR-92a-3p in the venous tissues significantly decreased and was negatively correlated with that of HO-1. The levels of p38MAPK and NF-κB p65 significantly decreased but that of P- IκBa and IκBa significantly increased. CONCLUSION: Resistance exercise intervention downregulated miR-92a-3p expression, repaired oxidative stress injury and prevented CRT formation.

Mechanism of injury and in-hospital mortality in penetrating jugular vein injuries: a National Trauma Data Bank (NTDB) study.

OBJECTIVE: Timely intervention is the key to the successful management of penetrating injuries to jugular veins; however, the optimal clinical management of these perforations and associated risk factors for mortality are not fully established. This study examined the trauma characteristics, vital signs, and in-hospital mortality in penetrating external and internal jugular vein injuries (PEJVI and PIJVI, respectively). PATIENTS AND METHODS: In this National Trauma Data Bank database study on patients with penetrating jugular vein injuries (PJVIs), details pertaining to demographics, comorbidities, type of injury, mechanism and intent of injury, Injury Severity Score (ISS), vital signs, treatment, and outcome, were abstracted. Multivariate logistic regression was used to identify the risk factors of in-hospital mortality. RESULTS: A total of 548 patients with PJVIs were included in the final analysis. Patients with PEJVI were more likely to have a self-inflicted injury (p<.001) than those with PIJVI. In both groups, hemorrhage control surgery was performed in almost 60% of the patients within 24 hrs. of the injury (p=.767). Systolic blood pressure (OR 0.99, 95% CI: 0.98-1.00, p=.043), Glasgow coma scale (OR 0.88, 95% CI: 0.81-0.95, p<.001), ISS (OR 1.10, 95% CI: 1.06-1.14, p<.001), and the firearm as a mechanism of injury (OR 2.85, 95% CI: 1.19-6.79, p=.018) were found to be independently associated with the risk of in-hospital mortality. CONCLUSIONS: The injury severity, hemodynamic stability, comma scale, intent, and mechanism of injury differed significantly in PEJVI and PIJVI; however, the type of PJVI did not have an independent association with in-hospital mortality.

Fístula carótida-yugular debido a trauma vascular con sierra de cadena. Enfoque diagnóstico y quirúrgico / Carotide-jugular fistula due to vascular trauma with chain saw. Diagnostic and surgical approach

INTRODUCCIÓN: el trauma carotídeo es una patología infrecuente pero generalmente devastadora, requiere un manejo diagnóstico y terapéutico oportuno. En los casos donde no hay inestabilidad hemodinámica o lesiones severas se puede incluir en el diagnóstico a la angiotomografía e incluso a la angiografía, que puede aportar datos fundamentales en el tratamiento. La cirugía convencional es de elección en muchos casos, determinada especialmente por las características de la lesión carotídea y por la disponibilidad de insumos endovasculares. CASO CLÍNICO: presentamos el caso de un paciente con lesión carotídea causada por un fragmento de sierra de cadena, que provocó una fístula carótido-subclavia. Se optó por la cirugía convencional que consistió en el cierre de la fístula y la angioplastia de la carótida interna con el uso de un parche en pantalón de safena mayor. DISCUSIÓN: el paciente se recuperó sin focalidades neurológicas

BACKGROUND: carotid trauma is an infrequent but generally devastating disease, requiring timely diagnostic and therapeutic management. In cases where there is no hemodynamic instability or severe injuries, angiotomography and even angiography can be included in the diagnosis, which can provide fundamental data in treatment. Conventional surgery is the choice in many cases, especially determined by the characteristics of the carotid lesion and by the availability of endovascular supplies. CASE REPORT: we present the case of a patient with a carotid lesion caused by a chainsaw fragment, which caused a carotid-subclavian fistula. Conventional surgery was chosen, which consisted of closing the fistula and angioplasty of the internal carotid with the use of a patch in the pants of the greater saphenous vein. DISCUSSION: the patient recovered without neurological focalities

Comparison of Nonoperative and Operative Management of Traumatic Penetrating Internal Jugular Vein Injury.

BACKGROUND: Small case series have suggested that selective nonoperative management (NOM) of penetrating internal jugular vein (IJV) injuries is safe and feasible in select patients lacking "hard signs" mandating exploration. Therefore, we sought to compare NOM to operative management (OM) of penetrating IJV injury, hypothesizing that both strategies have similar patient outcomes and mortality when patients are appropriately selected. METHODS: The Trauma Quality Improvement Program (2013-2016) was queried for patients with penetrating IJV injury with an abbreviated injury scale score of the neck ≥3. Demographics and patient outcomes were compared between patients undergoing NOM and patients undergoing OM, followed by a multivariable logistic regression model to analyze the risk of mortality. RESULTS: A penetrating IJV injury was identified in 188 (0.01%) patients meeting inclusion criteria, and OM was performed in 124 (66.0%) patients, whereas 64 (34.0%) patients underwent NOM. Although the OM group had a higher rate of pneumothorax (8.9% vs. 0.0%, P = 0.01), there was no difference in any other concomitant injuries or demographic data (all P > 0.05). The OM group had a higher rate of ventilator days (3 vs. 2 days, P = 0.01) but no other significant differences in morbidity or mortality (P > 0.05). After controlling for covariates, OM was associated with similar risk of mortality compared with NOM of patients with penetrating IJV injury (odds ratio 1.05, confidence interval 0.23-4.83, P = 0.95). CONCLUSIONS: The NOM of penetrating IJV injuries is associated with similar risk of morbidity and mortality compared with OM, suggesting that NOM may be used in appropriately selected patients. Future research is needed to determine the ideal patients suited for NOM and to identify risk factors and outcomes associated with failure of NOM.

Iatrogenic jugulo-subclavian fistula.

Iatrogenic arteriovenous fistula of major neck vessels is a rare complication but can occur after central venous catheterization. Symptoms can range from nothing to severe heart failure and management can be particularly complex. We report a case that we treated recently in our department.

Posterior wall penetration of the internal jugular vein during central venous catheter insertion using real-time ultrasound: Two case reports.

RATIONALE: Because central venous catheters (CVCs) are placed at the great vessels, mechanical complications can be fatal. Using the landmark method alone can make CVC difficult to access, depending on the skill of the operator and various patient conditions, such as anatomical variations of the vessels, young age, hypovolemic state, obesity, and short neck. Therefore, ultrasound (US)-guided techniques, including visualization of the vein and needle in the lumen of the vessel, are recommended. Nevertheless, our experience demonstrated that CVC malposition or vascular penetration cannot be prevented completely, even with real-time US guidance. PATIENT CONCERNS: The first patient was a 19-year-old woman (weight = 58 kg, height = 155 cm) who underwent CVC cannulation in the right internal jugular vein (IJV) under general anesthesia using real-time US. The second patient, a 50-year-old woman (weight = 51.6 kg, height = 155.7 cm), underwent CVC insertion in the right IJV using real-time US. DIAGNOSES: During guidewire insertion in the first case, the posterior wall of IJV was penetrated, and a break in the core body of the guidewire was detected. In the case of second patient, CVC was embedded in the posterior wall of IJV and misplaced in the interpleural space in the right thorax. In both cases, an out-of-plane US approach was used. INTERVENTIONS: In the first case, the broken guidewire was completely removed with real-time US guidance. In the second case, all fluid injected through CVC was aspirated, and then CVC was removed. OUTCOMES: In both cases, surgeries were completed successfully and all the patients were discharged without any complications. LESSONS: Even if the needle tip is located in the lumen of IJV and blood aspiration is confirmed on real-time US, vascular penetration or CVC malposition during the procedure cannot be completely prevented because of the limitation of the US imaging field. These results suggest that care must be exercised even during US-guided CVC placement and that alternative US-guided techniques or supplementary monitoring should be considered to confirm proper CVC position.

Shallow-angle needle guide for ultrasound-guided internal jugular venous catheterization: A randomized controlled crossover simulation study (CONSORT).

BACKGROUND: Needle guides for ultrasound-guided internal jugular venous catheterization facilitate successful cannulation. The ability of a needle guide to prevent a posterior vein wall injury which may secondarily induce lethal complications, is unknown. Previous studies showed that a shallow angle of approach may reduce the incidence of posterior wall injuries. We developed a novel needle guide with a shallow angle of approach for ultrasound-guided venous catheterization and examined whether this needle guide reduces the incidence of posterior wall injuries compared to a conventional needle guide and free-hand placement in a simulated vein. METHODS: This study was a randomized crossover-controlled trial. The primary outcome was the rate of posterior vein wall injuries. Participants had a didactic lecture about three ultrasound-guided techniques using the short-axis out-of-plane approach, including free-hand (P-free), a commercial needle guide (P-com), and a novel needle guide (P-sha). The view inside a simulated vein was recorded during venipuncture. RESULTS: Thirty-five residents participated in this study. Posterior vein wall injuries occurred in 66% using P-free, 60% using P-com, and 0% using P-sha (p< 0.01). There was no significant difference in the incidence of posterior vein wall injuries between P-free and P-com. CONCLUSIONS: Use of a shallow angle of approach needle guide resulted in a lower rate of posterior vein injuries during venipuncture of a simulated vein compared with other techniques using a steeper angle techniques.

Side-by-Side Stenting Repair of a Traumatic Pseudoaneurysm at a Venous Confluence.

OBJECTIVES: The incidence and prevalence of iatrogenic vascular trauma in the United States is staggering. This has led to the advent and implementation of more efficient and effective vascular repair methods. Although open surgical repair may still be considered gold standard, new endovascular solutions have emerged as other viable options. When using an endovascular approach, proper stent sizing is vital to a successful repair. METHODS: We present a case of a traumatic injury and pseudoaneurysm formation at the confluence of the right internal jugular and right subclavian veins during a central line placement. This iatrogenic pseudoaneurysm was treated with endovascular placement of side-by-side stents. A mathematical formula, which we have designated "Matteo's law," was utilized to select properly sized stent grafts to reconstruct the confluence and prevent infolding and endoleaks. RESULTS: After deployment of kissing stents at the confluence of the right internal jugular and right subclavian veins, a venogram was performed, which demonstrated successful exclusion of the pseudoaneurysm and no endoleaks. Clinical follow-up confirms continued wide open flow through the reconstructed venous confluence at 8 months post-procedure. CONCLUSION: In reconstruction of a venous confluence, selection of properly sized stent grafts is paramount to preventing infolding and endoleaks. Matteo's law states that the circumference of the native receiving vessel must equal the sum of the circumferences of both kissing stent grafts, subtracting the redundant material where the 2 stents interface.

Successful Double-Catheter Coil Embolization of an Iatrogenic Subclavian Artery to Internal Jugular Vein Fistula After Minimally Invasive Cardiac Surgery.

It is essential to establish cardiopulmonary bypass by percutaneous insertion of a large-bore catheter via both the femoral vein and internal jugular vein (IJV) for minimally invasive cardiac surgery (MICS). Complications associated with IJV catheterization during MICS have been reported in the literature; however, vascular injury of the subclavian artery (SCA) is rare. We herein present a rare case in which an iatrogenic arteriovenous fistula (AVF) between the right SCA and IJV after MICS was successfully treated by endovascular coil embolization. A 61-year-old man who had undergone mitral valve repair by MICS 10 months before presentation was referred because of pulsatile cervical bruit and tinnitus. Radiographic examination revealed a right SCA pseudoaneurysm associated with an AVF located between the right common carotid artery and vertebral artery. The AVF was completely occluded with detachable coils using a double-catheter technique to avoid coil migration into the IJV. This technique has been used to treat high-flow or complex AVFs, including pulmonary and renal AVFs. As shown in the present case, it is also useful to treat an iatrogenic AVF between the SCA and IJV.

[Iatrogenic carotid-jugular arterio-venous fistula: a rare complication associated with jugular venous catheterization (a case report)]. / Fistule artério-veineuse iatrogène carotido-jugulaire: une complication rare du cathétérisme de la veine jugulaire (à propos d'un cas).

Catheterization of the internal jugular vein is widely performed by both nephrologists and surgeons. It has become a routine procedure, but can be associated with serious complications. Carotid-jugular arterio-venous fistula (CJAVF) is a rare but potentially fatal complication. Very few cases have been reported in the literature. This study involved a patient with iatrogenic CJAVF following hemodialysis catheter placement performed three weeks earlier. The diagnosis was clinically suspected based on the discovery of laterocervical thrill and confirmed by echo-Doppler and angiography. The patient underwent successful open surgery. Operator experience and trainees support, in addition to the use of ultrasound guidance, can significantly reduce the occurrence of complications during jugular venous catheterization.

Anatomic Site-Specific Complication Rates for Central Venous Catheter Insertions.

BACKGROUND: Central venous catheter (CVC) complication rates reflecting the application of modern insertion techniques to a clinically heterogeneous patient populations are needed to better understand procedural risk attributable to the 3 common anatomic insertion sites: internal jugular, subclavian, and femoral veins. We sought to define site-specific mechanical and duration-associated CVC complication rates across all hospital inpatients. METHODS: A retrospective chart review was conducted over 9 months at Georgetown University Hospital and Washington Hospital Center. Peripherally inserted central catheters and tunneled or fluoroscopically placed CVC's were excluded. Mechanical complications (retained guidewire, arterial injury, and pneumothorax) and duration-associated complications (deep vein thrombosis or pulmonary embolism, and central line-associated bloodstream infections) were identified. RESULTS: In all, 1179 CVC insertions in 801 adult patients were analyzed. Approximately 32% of patients had multiple lines placed. Of 1179 CVCs, 73 total complications were recorded, giving a total rate of one or more complications occurring per CVC of 5.9%. There was no statistically significant difference between site-specific complications. A total of 19 mechanical complications were documented, with a 1.5% complication rate of one or more mechanical complications occurring. A total of 54 delayed complications were documented, with a 4.4% complication rate of 1 or more delayed complications occurring. There were no statistically significant differences between anatomic sites for either total mechanical or total delayed complications. CONCLUSIONS: These results suggest that site-specific CVC complication rates may be less common than previously reported. These data further inform on the safety of modern CVC insertion techniques across all patient populations and clinical settings.
