Central venous catheter tip misplacement: A multicentre cohort study of 8556 thoracocervical central venous catheterisations.

BACKGROUND: There is a paucity of data on the incidence of central venous catheter tip misplacements after the implementation of ultrasound guidance during insertion. The aims of the present study were to determine the incidence of tip misplacements and to identify independent variables associated with tip misplacement. METHODS: All jugular and subclavian central venous catheter insertions in patients ≥16 years with a post-procedural chest radiography at four hospitals were included. Each case was reviewed for relevant catheter data and radiologic evaluations of chest radiographies. Tip misplacements were classified as 'any tip misplacement', 'minor tip misplacement' or 'major tip misplacement'. Multivariable logistic regression analyses were used to investigate associations between predefined independent variables and tip misplacements. RESULTS: A total of 8556 central venous catheter insertions in 5587 patients were included. Real-time ultrasound guidance was used in 91% of all insertions. Any tip misplacement occurred (95% confidence interval) in 3.7 (3.3-4.1)% of the catheterisations, and 2.1 (1.8-2.4)% were classified as major tip misplacements. The multivariable logistic regression analyses showed that female patient gender, subclavian vein insertions, number of skin punctures and limited operator experience were associated with a higher risk of major tip misplacement, whereas increasing age and height were associated with a lower risk. CONCLUSIONS: In this large prospective multicentre cohort study, performed in the ultrasound-guided era, we demonstrated the incidence of tip misplacements to be 3.7 (3.3-4.1)%. Right internal jugular vein catheterisation had the lowest incidence of both minor and major tip misplacement.

Anatomical variations in the superficial venous system of the neck: an image-based study using contrast-enhanced computed tomography.

PURPOSE: The superficial venous system (SVS) of the neck receives blood from the face and oral cavity. The SVS comprises the anterior jugular vein (AJV), external jugular vein (EJV), and facial vein (FV). Comprehensive knowledge of the normal anatomy and potential variations in the venous system is valuable in surgical and radiological procedures. This study aimed to update the anatomic knowledge of the SVS using a radiographic approach, which is a beneficial data source in clinical practice. METHODS: Contrast-enhanced computed tomography images of the neck of patients with head and neck cancer treated between 2017 and 2020 were retrospectively evaluated. Each side of the neck was counted separately. A total of 302 necks of 151 patients were enrolled in this study. RESULTS: The medial AJV was absent in 49.7% (75/151) of the patients on the left side, which was significantly greater than the 19.2% (29/151) on the right (p < 0.001). The left AJV drained into the right venous system in 6.6% (10/151) of the necks. In 48.3% (146/302) of the necks, the FV did not flow into the internal jugular vein but rather into the EJV or AJV; these findings were significantly more frequent than those reported in previous studies. The diameters of the veins were significantly larger when they received blood from the FV than when they were not connected to the FV. CONCLUSION: These findings indicate that the AJV has a rightward preference during its course. The course of the FV is diverse and affects the diameter of connected veins.

Cannulation via the external jugular vein--An alternative to conventional peripherally inserted central catheterisation for paediatric patients.

PURPOSE: This study aimed to describe a peripherally inserted central catheterisation (PICC) for paediatric patients with inaccessible access and a high risk of general anaesthesia (GA). METHODS: This was a retrospective observational study involving all paediatric inpatients who performed the PICC via an EJV approach without GA between September 2014 and September 2021 in a provincial key clinical speciality. RESULTS: A total of 290 EJV line placement attempts were performed, and 29 were excluded due to missing placement results, resulting in a sample size of 261. The anatomical localisation, punctures, and catheterisation success rates for this practice were 100%, 100%, and 90.04%, respectively. The placement success rate in children younger than one year was 93.75% (45/48). The median line duration of use was 19 days, with a median length of catheter insertion of 13 cm. The most common complications were catheter malposition (n = 20) and dislodgement (n = 7). CONCLUSION: The PICC via an EJV approach without GA is a feasible and safe practice with acceptable success and complication rates, and low costs. It might be an attractive alternative for obtaining central vascular access for paediatric patients.

Supraclavicular cephalic vein draining into the internal jugular vein via the external jugular vein.

PURPOSE: The aim of this study is to report rare anatomical variations of the cephalic vein (CV) in a 77-year-old Korean male cadaver. CASE REPORT: On the right upper arm, the CV located lateral to the deltopectoral groove passed anterior to the clavicle at the lateral one-fourth of the clavicle without anastomosis to the axillary vein. It was connected to the transverse cervical and suprascapular veins by two communicating branches in the middle of its course at the neck, and opened into the external jugular vein at its junction with the internal jugular veins. The suprascapular and anterior jugular veins were flowed into the subclavian vein at the jugulo-subclavian venous confluence, and were connected by a short communicating branch. CONCLUSION: Detailed knowledge of the variations in the CV is expected to be helpful in decreasing unpredicted injuries and possible postoperative complications when invasive venous access is performed through the CV.

Surgical approach to internal and external jugular venous agenesis: case report.

PURPOSE: During reconstructive planning for mandibular resection and reconstruction, it was noted that the left internal and external jugular veins were absent, with a considerable compensatory internal jugular vein present on the contralateral side. METHODS: An accidental finding in the CT angiogram of the head and neck was assessed. RESULTS: Osteocutaneous fibular free flap is a well-established reconstructive surgery for mandibular defects that can involve anastomosis of the internal jugular vein and its tributaries. A 60-years-old man with intraoral squamous cell carcinoma, initially treated with chemoradiation, developed osteoradionecrosis of his left mandible. The patient then underwent resection of this portion of the mandible with reconstruction by osteocutaneous fibular free flap with virtual surgical planning. During reconstructive planning for the resection and reconstruction, it was noted that the left internal and external jugular veins were absent, and a noteworthy compensatory internal jugular vein was present on the contralateral side. We report a rare case of this combination of anatomical variations within the jugular venous system. CONCLUSION: Unilateral agenesis of the internal jugular vein has been reported, but a combined variation with ipsilateral agenesis of the external jugular vein and compensatory enlargement of the contralateral internal jugular vein has, to our knowledge, not been reported on previously. The anatomical variation reported in our study will be useful during dissection, central venous catheter placement, styloidectomy, angioplasty/stenting, surgical excision, and reconstructive surgery.

Management of external jugular vein aneurysm: a systematic review.

INTRODUCTION: Aneurysms of the jugular vein system are rare and high clinical suspicion is needed for diagnosis. External jugular vein aneurysms (EJVA) are considered innocent lesions that need treatment mainly for aesthetic reasons. The aim of this systematic review was to present current literature regarding diagnosis and management of EJVAs. METHODS: A literature review was conducted through the Pubmed/Medline and Scopus regarding articles referring on EJVA from 2000 to 2020. Using the PRISMA guidelines (Preferred Reporting Items for Systematic reviews and Meta-Analyses), 30 articles were identified, according to inclusion criteria. Demographics, clinical characteristics, etiology, diagnostic imaging, complications, treatment, and histopathological findings were recorded and analyzed. RESULTS: Twenty-seven case reports and one case series were identified, including 30 patients and 31 EJVAs. One-third of patients (30.3%) were < 18 years old (mean age 32 years, range 1-72 years) and 54% of them were females. In 51% of the cases, the lesion was characterized as a true aneurysm after histological evaluation. The presence of a soft cervical mass was the most common clinical symptom, while Valsalva maneuver pointed out the presence of an EJVA in 66.7% of patients. Diagnosis was achieved using ultrasonography, computed tomography, or magnetic resonance imaging. Forty-three percent of the patients underwent more than one radiological examination. Twenty patients underwent surgical management. The primary indication of surgical treatment was aesthetic reasons (11/20, 55%). Thrombosis was the most common EJVA complication (11/30, 36.3%). CONCLUSIONS: Differential diagnosis of neck mass should include EJVA. High clinical suspicion and adequate imaging are important for diagnosis. Open surgical approach is the more commonly applied therapeutic strategy.

External Jugular Vein Peripheral Intravenous Catheters: An Emergency Nurse's Guide.

Insertion of a peripheral intravenous catheter into the external jugular vein is regularly performed in emergency departments to treat patients with difficult intravenous access. Although emergency nurses are experienced in inserting peripheral intravenous catheters, there is an inconsistent practice and a lack of education and training regarding the insertion of catheters in the external jugular vein. This manuscript provides a practical guide for emergency nurses to care for patients who require an external jugular peripheral intravenous catheter. Key information found in this manuscript includes indications for external jugular intravenous access, the nurse's role in performing external jugular peripheral intravenous catheters, and clinical considerations when caring for patients with an external jugular peripheral intravenous catheter.

Supraclavicular nerve entrapment by the external jugular vein: An unreported finding.

OBJECTIVE: We aim to describe the supraclavicular nerve's vascular entrapment by the external jugular vein as an unreported anatomical finding. CASE DESCRIPTION: In a routine cadaveric dissection, the superficial emergence of the first division of the left supraclavicular nerve emerged along a duct formed through the external jugular vein. No other vascular or neural anatomical abnormalities were found in the surrounding structures. CONCLUSION: This unreported vascular entrapment of the supraclavicular nerve by the external jugular may harbour clinical implications for surgical and endovascular procedures on the external jugular vein and in refractory thoracic and scapular waist pain.

External Jugular Venous Cutdown versus Percutaneous Technique for Chemoport Insertion in Children: A Comparative Study.

Aims: We aimed to compare the external jugular vein (EJV) cutdown technique with the percutaneous technique for difficulties in insertion, maintenance, and other complications of chemoport placement in children. Materials and Methods: A retrospective study was carried out in children who underwent chemoport insertion between January 2007 and December 2019 either by EJV cutdown or percutaneous technique in the department of pediatric surgery at a tertiary center. All children aged <18 years undergoing chemoport insertion by EJV cutdown or percutaneous technique were included in the study. Data collected included the indication, procedure time, early and late complications, and the time to removal of chemoport. Results: There was no significant difference between the EJV group and the percutaneous group in terms of the time taken for chemoport placement (40.9 ± 7.6 min vs. 37.6 ± 18.9 min; P = 0.14), failure to cannulate (one vs. six; P = 0.05), and the mean chemoport indwelling days (816.8 ± 729.2 days vs. 854.5 ± 705.1 days; P = 0.73). The chemoport placement by EJV cutdown method was found to have significantly fewer overall complications (4 vs. 14; P = 0.01) and a lesser rate of premature chemoport removal (4 vs. 12; P = 0.04) compared to the percutaneous group. Conclusions: Chemoport placement by the EJV cutdown was found to have fewer port-related complications and a lesser rate of premature chemoport removal compared to the percutaneous technique. The time taken for port placement and the mean chemoport-indwelling days were similar in both techniques.

Spontaneous external jugular vein pseudoaneurysm treated by thrombin injection: Case report and literature review.

Although external jugular vein (EJV) aneurysms are infrequent, regardless of etiology, spontaneous pseudoaneurysms (PAs) are extremely rare and generally require surgery. We describe a case of spontaneous PA of the EJV, which was successfully treated by percutaneous thrombin injection.

Unusual and multiple variations of head and neck veins: a case report.

We report an unusual and multiple variation involving the right head and neck veins which were found during routine dissection in a 50-year-old male cadaver, facial vein draining into both external and internal jugular veins, fenestration in external jugular vein transmitting the supraclavicular nerve trunk, the anterior division of the retromandibular vein draining into anterior jugular vein and the absence of the common facial vein. The knowledge about these variations is important during various surgical and diagnostic procedures involving head and neck region.

Unusual course and termination of common facial vein: a case report.

Given the common and increasing exploitation of superficial head and neck veins in a widening spectrum of clinical and surgical procedures, it is important to equally broaden understanding of the heterogeneity of the vascular anatomy of the region. We report an unusual course of the right common facial vein parallel to the course of external jugular vein, emptying into the ipsilateral subclavian vein in the lateral neck triangle behind the posterior border of the sternocleidomastoid muscle in a 78-year-old male cadaver. Such course may be hazardous for surgical procedures in the region given the high risk of profuse haemorrhage from any injury of the vessel. The variant anatomy may also cause problems in invasive techniques involving the vein, especially in emergency and intensive care settings. This index report, therefore, provides a new insight into the superficial head and neck vein anatomical variations in order to guide relevant clinical procedures in the region.

External jugular vein hemangioma: case report.

Hemangioma is a common tumor, normally diagnosed in children, and accounting for almost 10% of benign neoplasms. A hemangioma arising from the wall of a vessel is rare, and must be differentiated from other vascular malformations of the same origin. We report a rare case of a hemangioma arising from the wall of an external jugular vein and discuss diagnostic work-up and management.

Embryological and comparative description of the cephalic vein joining the external jugular vein: A case report.

The cephalic vein arises from the radial end of the dorsal venous arch. It turns around the radial border of the forearm and passes proximally along the arm to the shoulder, where it enters the axillary vein by penetrating the clavipectoral triangle. The cephalic vein is prone to vary at the antecubital fossa, where it forms numerous anastomoses. A male cadaver fixated with a 10% formalin solution was dissected during regular anatomy lessons. It was found that the cephalic vein crossed the upper third of the arm between two fasciculi of the deltoid muscle and reached the shoulder, where it passed above the acromion and crossed the posterior border of the clavicle in order to join the external jugular vein. The cephalic vein is one of the most used veins for innumerous activities, such as venipunctures and arteriovenous fistula creation. Furthermore, it is an anatomical landmark known for its consistent anatomy, as it possesses low rates of variability. Despite that, its anatomical variations are clinically and surgically significant and healthcare professionals must be aware of the variations of this vessel. We aim to report a rarely described variation of the cephalic vein and discuss its embryological, phylogenetic and clinical features.

A novel "shrug technique" for totally implantable venous access devices via the external jugular vein: A consecutive series of 254 patients.

BACKGROUND: The external jugular vein (EJV) approach for totally implantable venous access devices (TIVADs) is safe. However, the success rate is unsatisfactory because of the difficulty in catheterization due to the acute angle between the EJV and the subclavian vein (SCV). A novel "shrug technique" to overcome this difficulty was developed, and its efficacy was assessed in a consecutive case series. METHODS: TIVAD placement was performed via the EJV cut-down approach. "Shrug technique," a simple way to straighten the EJV-SVC angle by shrugging the patient's shoulder, was applied to facilitate the passage of the guidewire and sheath-introducer when there was acute angulation between the EJV and SCV. RESULTS: A total of 254 patients underwent TIVAD implantation by the EJV cut-down approach. The "shrug technique" was applied in 51 cases (20%), and catheterization was successful in all cases. Thus, TIVAD implantation was successfully completed in all 254 cases (100%) in a single operative setting. The median operating time was 38 [IQR 30-45] min. Eleven complications (4%) were observed, but none of them were EJV-specific. CONCLUSION: The "shrug technique" is simple but very useful to achieve a higher success rate and safer insertion of TIVADs from the EJV. J. Surg.

A congenital external carotid artery-external jugular vein arteriovenous fistula was successfully treated by coil embolization (case report and literature review).

OBJECT: Congenital arteriovenous fistula involving the external carotid system is rare. METHODS: This paper reports a case of congenital external carotid artery-external jugular vein arteriovenous fistula admitted to Xuanwu Hospital, and reviews the literature. RESULTS: The patient was a boy, 9 years old, with a history of pulsatile mass and thrill in the right neck since his birth. External carotid artery-external jugular vein fistula was confirmed by the digital subtraction angio-graphy. And coil embolization was done later. Postoperative immediate angiography confirmed the complete occlusion of the fistula, and partial branch of the external carotid artery can be seen. The abnormal clinical manifestation disappeared after the procedure without any complications. CONCLUSION: This case and relevant literatures remind us that congenital external carotid artery-external jugular vein arteriovenous fistula has its unique features, and it can be treated by coil embolization safely and effectively.

Persistent jugulocephalic vein: case report including commentaries on distribution of valves, blood flow direction and embryology.

This paper is a detailed case study of the persistent anastomotic channel between the cephalic vein and the external jugular vein, running anterior to the clavicle, corresponding to the jugulocephalic vein present at early stages of the ontogenesis in humans. This connection is not only a relic of early foetal development seldom occurring in adults, but it may also be of clinical significance, increasing the risk of complications during the cephalic vein catheterisation, clavicular fractures or head and neck surgery. The novelty in this paper was to determine the presence and distribution of valves within the persistent jugulocephalic vein. Three bicuspid venous valves were found that allowed the blood to flow only in one direction - from the cephalic vein to the external jugular vein. The anastomosis between the persistent jugulocephalic vein and the thoracoacromial veins was additionally present. Due to lack of similar data in the literature, further research should be performed on the presence and distribution of the venous valves in various types of the persistent jugulocephalic vein in humans.

Three superficial veins coursing over the clavicles: a case report.

We report a unique bilateral combination of multiple variations in the superficial venous system of the neck of a 77-year-old male cadaver. On the right side of the neck, the external jugular vein (EJV) crossed superficial to the lateral third of the clavicle constituting a common trunk with the cephalic vein (CV) that drained into the subclavian vein (SCV). On the left side the EJV descended distally, passed over the anterior surface of the medial third of the clavicle and drained into the SCV. The posterior external jugular vein (PEJV) crossed superficial to the lateral third of the clavicle and terminated into the CV, providing an additional communicating branch to the EJV. Knowledge of both normal and abnormal anatomy of the veins of the neck plays an important role for anesthesiologists or cardiologists doing catheterization, orthopedic surgeons treating clavicle fractures and general surgeons performing head and neck surgery, to avoid inadvertent injury to these vascular structures.

Multiple variations of the superficial jugular veins: case report and clinical relevance.

The jugular venous system constitutes the primary venous drainage of the head and neck. It includes a profundus or subfascial venous system, formed by the two internal jugular veins, and a superficial or subcutaneous one, formed by the two anterior and two external jugular veins. We report one case of unilateral anatomical variations of the external and anterior jugular veins. Particularly, on the right side, three external jugular veins co-existed with two anterior jugular veins. Such a combination of venous anomalies is extremely rare. The awareness of the variability of these veins is essential to anesthesiologists and radiologists, since the external jugular vein constitutes a common route for catheterization. Their knowledge is also important to surgeons performing head and neck surgery.

External jugular venous aneurysm-a case report.

Aneurysms of the external jugular vein (EJV) are uncommon vascular malformations. Due to their rarity, it is currently unclear what the risk of complications are and whether surgical management should be offered. The risks associated with the surgery need to be balanced with the risk of complications from the malformation. We present the case of a young woman who presented with a painful erythematous neck swelling who was found to have an aneurysm of the EJV with thrombophlebitis. This was successfully treated with surgical excision. We discuss current evidence for treatment of neck vein aneurysms and pitfalls.
