BACKGROUND: Structural features of the patients vascular system can cause unintended complications when providing vascular access and can disorient the specialist in assessing the location of the installed catheter. This study aimed to demonstrate anatomical features of the vascular system of the superior vena cava and diagnostic steps when providing vascular access in a child. CASE REPORT: Patient K (3 years old) was on planned maintenance of long-term venous access. Preliminary ultrasound examination of the superior vena cava did not reveal any abnormalities. Function of the right internal jugular vein under ultrasound control was performed without technical difficulties; a J-formed guidewire was inserted into the vessel lumen. X-ray control revealed its projection in the left heart, which was regarded as a technical complication, so the conductor was removed. A further attempt to insert a catheter through the right subclavian vein led to the same result. For a more accurate diagnosis, the child underwent computed angiography of the superior vena cava system. Congenital anomalies of the vascular system included aplasia of the superior vena cava and persistent left superior vena cava. Considering the information obtained, the Broviac catheter was implanted under ultrasound control through the left internal jugular vein without technical difficulties with the installation of the distal end of the catheter into the left brachiocephalic vein under X-ray control. CONCLUSION: A thorough multifaceted study of the vascular anatomy helps solve the anatomical issues by ensuring vascular access and preventing the risks of complications.

Internal jugular veins (IJVs) are the largest veins in the neck and are considered the primary cerebral venous drain for the intracranial blood in supine position. Any reduction in their flow could potentially results an increase in cerebral blood volume and intracranial pressure (ICP). The right internal jugular vein communicates with the right atrium via the superior vena cava, in which a functional valve is located at the union of the internal jugular vein and the superior vena cava. The atrium aspiration is the main mechanism governing the rhythmic leaflets movement of internal jugular vein valve synchronizing with the cardiac cycle. Cardiac contractions and intrathoracic pressure changes are reflecting in Doppler spectrum of the internal jugular vein. The evaluation of the jugular venous pulse provides valuable information about cardiac hemodynamics and cardiac filling pressures. The normal jugular venous pulse wave consists of three positive waves, a, c, and v, and two negative waves, x and y. A normal jugular vein gradually reduces its longitudinal diameter, as described in anatomy books; it is possible to segment IJV into three different segments J3 to J1, as it proposed in ultrasound US studies and CT scan. In this review, the morphology and methodology of the cerebral venous drainage through IJV are presented.

Superior vena cava (SVC) syndrome is typically associated with malignant tumors obstructing the SVC, but as many as 40% of cases have other etiologies. SVC obstruction was previously described during veno-venous extracorporeal membrane oxygenation therapy (VV ECMO) in children. In this report, we describe a woman with adult respiratory distress syndrome resulting from infection with coronavirus-19 who developed SVC syndrome during VV ECMO. A dual-lumen ECMO cannula was inserted in the right internal jugular vein, but insufficient ECMO circuit flow, upper body edema, and signs of hypovolemic shock were observed. This clinical picture resolved when the right internal jugular vein was decannulated in favor of bilateral femoral venous cannulae. Our report demonstrates that timely recognition of clinical signs and symptoms led to the appropriate diagnosis of an uncommon ECMO complication.

Background: Thyroid cancer with massive invasion into the cervical and mediastinal great veins is extremely rare, and the surgical treatment is controversial, thus posing a great challenge for head and neck surgeons. Here, we report our successful experiences in reconstructing the superior vena cava (SVC) system to treat thyroid cancer with an extensive tumor thrombus growing intraluminally into the SVC.Case Presentation: From September 2019 to September 2020, three patients with superior vena cava syndrome(SVCS) caused by tumor thrombus invasion from thyroid cancer were continuously included in this series. After preoperative evaluation, radical resection and reconstruction of the SVC system with expanded polytetrafluoroethylene (EPTFE) grafts were performed. In addition, bypass support from the right internal jugular vein to the right femoral vein was routinely prepared intraoperatively to prevent a rise in central venous pressure (CVP). Postoperatively, SVC-related syndrome improved immediately after the operation. Imaging examination showed good function of the reconstructed venous system. The patients recovered well with no surgical complications and remain under continuous follow-up.Conclusions: Tumor growth into the SVC does not seem to be an absolute contraindication for surgery for thyroid carcinoma. Comprehensive treatment, including reconstruction of the SVC, is effective for relieving symptoms and preventing disease progression and is thus worth advocating. In addition, bypass support from the internal jugular vein to the femoral vein is easy to implement and can improve the safety of the operation.

For insertion of totally implantable access ports, with the catheter end in the superior vena cava, the percutaneous (Seldinger) technique is commonly used. Of cutdowns, the cephalic vein cutdown is the most popular one (success rate about 80%), followed by the external jugular vein cutdown. Our preliminary experience suggests that internal jugular vein and basilic vein cutdowns have the anatomic features to prove both of them superior to the cephalic vein cutdown.

The objective is to compare Multi-detector CT angiography (MDCTA) and digital subtraction angiography (DSA) in diagnosing hemodialysis catheter related-central venous stenosis (CVS). During a period of 6 years, hemodialysis patients with suspected catheter related-CVS who received both MDCTA and DSA were retrospectively enrolled. We analyzed the sensitivity, specificity, accuracy, Cohen’s kappa coefficient (κ) and other diagnostic parameters for MDCTA compared to DSA. A total of 1533 vascular segments in 219 patients were analyzed. Among the 280 lesions identified by DSA, 156 were correctly identified by MDCTA. There were 124 false negative and 41 false positive diagnoses. MDCTA had a high specificity (96.73%) but a low sensitivity (55.71%), with a moderate inter-test agreement (κ = 0.5930). In stratified analyses of vascular segments, the specificities of MDCTA were 89.93% (superior vena cava), 98.95% (left brachiocephalic vein), 95.33% (right brachiocephalic vein), 99.53% (left subclavian vein), 97.61% (right subclavian vein), 97.13% (left internal jugular vein), and 95.86% (right internal jugular vein), while the sensitivities were 90.00%, 65.52%, 66.67%, 87.50%, 40.00%, 20.00% and 8.11%, respectively. Good to excellent inter-test agreement was observed for the superior vena cava (κ = 0.7870), left brachiocephalic vein (κ = 0.7300), right brachiocephalic vein (κ = 0.6610), and left subclavian vein (κ = 0.8700) compared with poor to low agreement for the right subclavian vein (κ = 0.3950), left internal jugular vein (κ = 0.1890), and right internal jugular vein (κ = 0.0500). MDCTA had a high specificity in diagnosing hemodialysis catheter related-CVS. Its sensitivity varied by central venous segments, with better performance in superior vena cava and brachiocephalic veins.
