Interruption of the inferior vena cava with azygos continuation is a rare congenital anomaly. This anomaly becomes clinically important during cardiac interventions.

Background: Critical pulmonary stenosis (PS) is one of the life-threatening congenital heart diseases which present during the neonatal period with cyanosis. Surgical valvotomy was once the procedure of choice for critical PS; however, balloon pulmonary valvuloplasty (BPV) has now become the standard treatment. Although the procedure is usually simple, crossing the pulmonary valve from the femoral vein can be difficult, especially when severe tricuspid regurgitation and right atrium dilatation are present. In such patients, the maneuver can be simplified by using the right internal jugular vein approach. However, many operators are reluctant to use this approach because of unfamiliarity with the technique, potential complications, and paucity of reports. Until now, there is no literature describing BPV using the transjugular approach in neonates, also none directly comparing the transfemoral and transjugular approaches. Objective: We compared transjugular with the transfemoral approach in terms of procedure time and complications. Materials and Methods: This was a retrospective cohort study. Participants were neonates with critical PS undergoing BPV in the National Cardiovascular Center Harapan Kita from 2013 to 2018. Results: Of 15 neonates undergoing BPV, eight were done using the transjugular approach and seven using the femoral approach. Mean age and weight in both groups was similar. In all eight patients using transjugular approach, crossing the pulmonary valve was consistently quick and easy. The total procedural time, pulmonary crossing time, and fluoro time was significantly shorter using the transjugular approach (65 ± 8 vs. 108 ± 17.8 min, P < 0.05; 22 ± 3.1 vs. 45 ± 14.8 min, P < 0.01; 29 ± 13 vs. 67 ± 35 min, P < 0.05). There were no complications relating to vascular access. Moreover, the BPV procedure itself demonstrated comparable results in both groups. Conclusion: BPV using the transjugular approach is safe and effective to relieve critical PS in neonates compared to the transfemoral approach.

Awareness of persistent left superior vena cava (PLSVC), a rare congenital variant is helpful to a clinician to avoid the unnecessary complications. We report a case of PLSVC in a patient with chronic kidney disease which was identified following a difficult catheterization into the right internal jugular vein (IJV). The catheterization was attempted through the left IJV and the position of which could not be confirmed with check radiograph and two-dimensional echo. PLSVC was suspected in the computed tomography angiography and was confirmed following digital subtraction angiography.

INTRODUCTION We studied the effect of head rotation on the relative position of the right common carotid artery (CCA) and the right internal jugular vein (IJV) in patients with laryngeal mask airway (LMA) insertion to evaluate the accuracy of anatomical landmarks for right IJV cannulation. METHODS We simulated needle insertion to the right IJV on sonograms via the central landmark approach and an approach using the external jugular vein, in patients with LMA insertion (n = 50) or endotracheal intubation (E-tube, n = 50). Overlap index and successful simulation rates were measured according to the different degrees of head rotation. RESULTS The overlap index between the right CCA and the right IJV increased with greater degrees of head rotation. It was significantly greater in the LMA insertion group than in the E-tube group in the following head rotation positions: neutral, 15° and 45°. The success rate of the simulation was lower in the LMA insertion group than in the E-tube group. In the LMA insertion group, the success rate of the simulation was highest (62%) with the central landmark approach and in the 15° head rotation position. CONCLUSION In the LMA insertion group, the overlap index increased incrementally with greater head rotation degrees (from neutral to 45°). The central landmark approach and 15° head rotation position appear to be the optimal puncture site and degree of head rotation for right IJV cannulation in patients with LMA insertion.

Background: Right internal jugular vein (RIJV) is the most commonly used site for central venous cannulation. Ultrasound guidance has increased success rate and reduced complications of central venous cannulation. The main aim before cannulation is to increase the size of the vein by optimal positioning. We used ultrasound to assess changes in right internal jugular diameter with use of a head pillow and shoulder roll and their effect on the degree of overlap between RIJV and carotid. Methodology: 106 patients were recruited in the study. After intubation the patients were placed in the following 3 positions (i) P1 -without head pillow or shoulder roll, (ii) P2 - with head pillow and (iii) P3- with shoulder roll. All measurements were made in 15 degree Trendelenberg tilt and head turned to the left by 30 degree. The following measurements were recorded in all 3 positions. (a) Transverse and Antero-Posterior diameter of the RIJV. (b) Transverse diameter of the right carotid. (c) Overlap between RIJV and carotid. Results: In our study the mean transverse diameter of RIJV was 1.87cm in P1 and P2 and 1.72 cm in P3respectively. The mean antero-posterior diameter was 1.39cm, 1.37cm and 1.13 cm in P1, P2 and P3 respectively. The increase in diameter in P1 was statistically significant (P < 0.001). The mean overlap percentage between right carotid and RIJV was 49.41%, 50.97% and 35.7% in P1, P2 and P3 respectively. This difference between P3 and other two position was also statistically significant (P < 0.00). Conclusion: We conclude that placing the patient supine in 15 degree Trendelenberg tilt and a30 degree head rotation to the opposite side with or without use of a head pillow would lead to greater chance of first pass success during R IJV cannulation as the diameter was found to be maximum in this position. We do not recommend use of a shoulder roll as there was significant reduction in diameter though the overlap between RIJV and carotid was found to be minimal. Use of ultrasound and proper positioning of the patient will reduce the possible catastrophic complications associated with RIJV cannulation.

Between January 2003 till September 2004, twenty-five venous access devices have been implanted in 25 children with various types of cancer. Healthport Mini MAX (Baxter) was inserted in 19 patients and Vortex 7.2 F (HMP) in 6 patients. The catheter was inserted percutaneously in the right internal jugular vein or the right subclavin vein. Cumulative total venous access was 7321 patient-days; mean 293 days per patient, range 8-638 days. Infection and occlusion were the only complications encountered in 4 patients. With proper placement technique and adequate nursing care they represent a definite improvement in pediatrie cancer therapy.

Central vascular access in critically ill paediatric patients is, many times, a challenge for physicians due to the number of lines needed for multiple infusions. We present ultrasound-guided placement of a double catheter in the right internal jugular vein in two patients that required multiple central lines for management.Key words: Double catheter, jugular vein, ultrasound-guided

One of disastrous complications of central venous cannulation (CVC) is malposition of central venous catheter. In this case report, we present an adult patient with history of multiple trauma and intracranial hemorrhage in whom the right axillary vein was accidentally cannulated during CVC insertion.
