SUMMARY In order to obtain exclusive long-term access to both the arterial and venous sides of the ovarian circulation in the ewe, a technique was evolved for vascular autotransplantation of the ovary. The first stage consisted of the preparation of a carotid artery—jugular vein skin tube, with a pouch to receive the ovary and its pedicle. In the second stage, performed at least 2 months later, the left ovary and its pedicle were removed together with an aortic patch which included the orifice of the ovarian artery. The aortic patch was inlaid into the carotid artery to provide the arterial supply to the transplanted ovary; venous drainage was achieved by end-to-side anastomosis of the termination of the middle uterine vein to the jugular vein. The right ovary was removed. The transplanted ovary was shown to have an unimpaired circulation. Ovarian function was demonstrated by histological and behavioural evidence, and by demonstration of a cyclical secretion of progesterone. The rate of progesterone secretion was < 5 μg./hr. at oestrus and rose to approximately 200 μg./hr. in the luteal phase of the cycle which is within the range reported for the ovary in situ.

Extracorporeal membrane oxygenation is an important technology in the treatment of high-risk infants whose long-term outcome is being followed prospectively at our institution. The extracorporeal membrane oxygenation procedure allows temporary cardiopulmonary support for critically ill full-term neonates who are refractory to maximum ventilatory and medical management as a consequence of severe persistent pulmonary hypertension. The technique necessitates both the permanent ligation of the right common carotid artery and jugular vein and systemic heparinization. The survivors constitute a unique group of high-risk infants, from the standpoint of the hypoxic-ischemic insults preceding extracorporeal membrane oxygenation and the risks associated with the procedure. Our results indicate that most of our survivors are developing normally at 1 year. Major morbidity, in terms of either significant developmental delay (Bayley mental and motor indices less than 70) or significant neuromotor abnormality, occurred in only 10% of these infants. Poor outcome was associated with major intracranial hemorrhage and chronic lung disease. Ligation of the right carotid artery and jugular vein was not associated with a consistent lateralizing lesion. Long-term follow-up through school age is essential.

Introduction: The internal jugular vein locates anterior or anterolateral to the common carotid artery in two-thirds of the subjects studied by ultrasound when the head is in a rotated position. Aim: To identify variables associated with the anterior location of the internal jugular vein. Methods: Ultrasound examinations were performed with the patients in the supine position, with the head rotated to the opposite side. The proximal third of the neck was visualized transversely with a 7.5-mHz transducer. The relationship between the vessels was described in accordance with the proportion of the artery overlapped by the vein. Univariate comparisons and a multivariate analysis of potential variables that may affect the anatomic relationships were performed. Results: Seventy-eight patients were included, 44 of whom were men. The patients' ages ranged from 17 to 90 years (median 64.0, interquartile range 41-73). The right and left sides were studied 75 and 73 times, respectively. The vein was located lateral to the artery in 24.3% (95%CI= 17.4-32.2) of the studies, anterolateral in 33.8% (95%CI= 26.2-41.4) and anterior in 41.9% (95%CI= 33.9-49.8). The multivariate analysis identified age group (OR= 3.7, 95% CI 2.1-6.4) and, less significantly, the left side (OR= 1.7, 95%CI= 0.8-3.5) and male gender (OR= 1.2, 95%CI= 0.6-2.7) as variables associated with the anterior position of the vein. Conclusión: The anterior position of the internal jugular vein relative to the common carotid artery increases gradually with age. Additionally, left-sided localization and male sex further increased the probability of an anterior position.

This prospective clinical investigation assessed the effect of placement of a Univent® tube on the anatomy of the internal jugular veins and the success of cannulation of the left internal jugular vein. After obtaining informed consent, 48 adult patients were enrolled. Of these, 42 patients were eligible and were divided into two groups: Univent® tube (group U, n=21) and wire enforced endotracheal tube (group C, n=21). The Univent® tube group were having a left thoracotomy. Using horizontal ultrasound scans just above the thyroid gland, the internal jugular vein was visualized and measured before and after Univent® placement. The number of needle passes necessary to cannulate the left internal jugular vein in the two groups was also compared. Univent® tubes were associated with lateral displacement of the right carotid artery and internal jugular vein on the convex side of the Univent® tube, with compression of the right internal jugular vein by the artery, resulting in a kidney-shaped cross-section of the vein. On the left (concave side of the tube), the neck was indented, the sheath of the left carotid artery was displaced medially, and the left internal jugular vein distorted to an ellipse. There was a significant increase in the lateral diameter and a decrease in the cross-sectional area of the left internal jugular vein (t-test, P<0.05). The first attempt at cannulation of the left internal jugular vein failed significantly more often in the Univent® group (13/21 vs 5/21 in group C, Chi-square 6.22, P=0.025). Cannulation of the internal jugular vein before placement of the Univent® tube, or placement with ultrasound guidance is suggested.

Speed And Accuracy

Introduction: Tunneled cuffed catheters provide stable, instantaneous, long-term intravenous access for hemodialysis. Because catheterization is often performed in emergency situations, speed and accuracy are emphasized. Methods: We retrospectively compared the Micropuncture kit with the standard 18-gauge Angiocath IV catheter for tunneled cuffed catheter insertion in the right jugular vein. From June 2016 to May 2017, 31 tunneled cuffed catheters were successfully inserted via the Micropuncture kit and another 31 via the Angiocath IV catheter. All patients underwent the same ultrasound-guided procedure performed by a single experienced interventionalist. Procedure time was the time from draping of the patient to the completion of povidone dressing after the catheterization. In our center, the Angio Lab nurse maintains records, including procedure time and method for every procedure. All patient records were retrospectively tracked through electronic medical record review. The primary outcome was procedure time and the secondary outcomes were complications and cost-effectiveness. Results: There were no significant differences in the patients’ demographic data between the two groups. However, procedure time was significantly shorter in the Angiocath group than in the Micropuncture group (12.4 ± 3.5 vs 17.6 ± 6.9 min, p = 0.001); there were no serious complications, such as hemorrhage, pneumothorax, or hematoma, in both groups. Moreover, cost-effectiveness was better in the Angiocath group than in the Micropuncture group (0.34 vs 52 US$, p < 0.01). Conclusions: Using the Angiocath IV catheter can reduce procedure time and cost with no severe complications. Moreover, experienced practitioners can reduce the risk of complications when using Angiocath. There are several limitations to this study. First, it was retrospective; second, it was not randomized; and finally, it was conducted by only one experienced interventionalist.

A special lung support technique is required during carina! or tracheal surgery. Veno venous extracorporeal membrane oxygenation (ECMO) has become an accepted techinique for temporary lung support. Therefore, the purpose of our experiments was to evaluate the effect of veno venous ECMO (veno-right ventricle bypass) without ventilatory support. In five mongrel dogs, two venous drainage cannula were inserted into the superior vena cava through the right jugular vein and the inferior vena cava through the right femoral vein. In addition, a venous return cannula was inserted into the right ventricle (RV) through the right jugular vein. The veno-right ventricle (veno-RV) bypass system was composed of a centrifugal pump and membrane oxygenator; pump flow was maintained at 88 ± 14 ml/kg/min. Excellent hemodynamics and good oxygenation were obtained. On the basis of these results, we conclude that veno-RV bypass may be used as lung support during pulmonary surgery even though the native lung is not ventilated during the veno-RV bypass procedure.

Venous Pulse

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.

Background: The commonly preferred right internal jugular vein was investigated in terms of its dimensions, the relationship between its dimensions and anthropometric measures, and the outcomes of its cannulation in infants. Data regarding its position with respect to the carotid artery indicated anatomical variation. Aim: The aim of this study was to share our observations pertaining to the anatomy and position of the right internal jugular vein with respect to carotid artery using ultrasound and our experience with ultrasound-guided right internal jugular vein access in neonates and small infants. Materials and methods: A total of 25 neonates and small infants (<4000 g) undergoing ultrasound-guided central venous cannulation via right internal jugular vein within a 6-month period were included. Ultrasound-guided anatomical evaluation of the vein was used to obtain the transverse and anteroposterior diameters, the depth from skin and the position with respect to the carotid artery. Real-time ultrasound-guided central cannulation success rates and complication rates were also obtained. The patients were divided into two groups with respect to their weight in order to compare both the position and the dimensions of right internal jugular vein and cannulation performance in infants weighing <2500 g and ⩾2500 g. Results: The position was lateral to the carotid artery in 84% of all infants and similar in both groups. The first-attempt success rates of cannulation were similar (70% vs 73.3%) in both groups, with an overall success rate of 88%. Conclusion: Right internal jugular vein revealed a varying position with respect to carotid artery with a higher rate of lateral position. The presence of such anatomical variation requires ultrasonographic evaluation prior to interventions and real-time guidance during interventions involving right internal jugular vein.

Abstract 40 year-old male with history of congenital heart disease. Atrial septal defect (ASD) sinus venosus type associated with partial anomalous pulmonary venous drainage (PAPVD) was diagnosed during childhood and surgically repaired at the age of three. Since then the patient was asymptomatic and he was lost to follow up when reached adulthood. A transthorathic echocardiogram was performed during a hospitalization because of a complicated pneumonia. A severe dilatation of right chambers and main pulmonary artery was observed. The estimated Qp:Qs by this technique was 2.0 but the atrial septum seemed to be intact. Agitated saline was administered in this procedure and no passage of microbubbles was observed. A cardiac MRI was performed because of suspicion of anomalous pulmonary venous drainage. The findings observed in the echocardiogram were confirmed and an uncommon PAPVD was demonstrated by this technique: the superior left pulmonary vein drainaged into a dilated innominated vein. Also, a small pulmonary vein from the right upper lobe emptied into a "venous conduct" (yellow circle) located posterior to the superior cava vein (SCV) that later drainaged into the right atrium under the mouth of the SVC, posterior to the interatrial septum. Surgically correctioin of the PAPVD was performed. Discussion PAPVD is a congenital heart disease characterized by the drainage of one or several pulmonary veins –but not all of them- into the right atrium or systemic veins, which leads to left-to-right shunting. The estimated incidence of this disease ranges between 0.1 and 0.2% of the general population. The right superior pulmonary vein is the most frequently involved and is commonly associated to ASD sinus venosus type. Bilateral anomalous drainage, as occurred in this case, is exceptional. Furhermore, this case highlights the importance of long-term follow-up in patients with congenital heart disease due to the fact that, even when the disease is considered to be cured, long term complications could appear compromising the prognosis of the patient.
