Abstract Blood sample collection from the caudal vena cava at the site of uterine–ovarian drainage provides a more exact evaluation of the concentration and pattern of secretion of uterine or ovarian secreted products for studies of reproductive processes in cyclic and pregnant cattle compared with samples collected from general circulation. This paper describes a thorough and updated procedure for cannulating the coccygeal vein into the caudal vena cava for the collection of serial blood samples at or near the site of uterine–ovarian drainage. Concentrations of progesterone were quantified in cows of different reproductive tract sizes with an active corpus luteum to assess the distance for proper catheter placement compared with circulating concentrations collected from the jugular vein. This procedure has a low risk for side effects, can be used effectively in pregnant animals with no major consequence to the viability of the pregnancy, and provides means for frequent collections up to 12 d.

Abstract Background Bedside ultrasound helps to estimate volume status in critically ill patients and has traditionally relied on diameter, respiratory variation, and collapsibility of the inferior vena cava (IVC) to reflect fluid status. We evaluated collapsibility of the internal jugular vein (IJ) with ultrasound and correlated it with concomitant right heart catheterization (RHC) measurements in patients with presumed pulmonary hypertension. Methods and results We studied 71 patients undergoing RHC for evaluation of pulmonary hypertension. Using two-dimensional ultrasound (Sonosite, Washington, USA), we measured the diameter of the IJ at rest, during respiratory variation, and during manual compression. Collapsibility index during respiration (respiratory CI) and during manual compression (compression CI) was calculated. We correlated mean right atrial pressure (mRAP) and pulmonary artery occlusion pressure (PAOP) defined by RHC measurements with respiratory and compression CI. A secondary goal was examining correlations between CI calculations and B-type natriuretic peptide (BNP) levels. Baseline characteristics demonstrated female predominance (n = 51; 71.8%), mean age 59.5 years, and BMI 27.3. There were significant correlations between decrease in compression CI and increase in both mRAP (Spearman: − 0.43; p value = 0.0002) and PAOP (Spearman: − 0.35; p value = 0.0027). In contrast, there was no significant correlation between respiratory CI and either mRAP (Spearman: − 0.14; p value = 0.35) or PAOP (Spearman:− 0.12; p value = 0.31). We also observed significant negative correlation between compression CI and BNP (Spearman: − 0.31; p value = 0.01) but not between respiratory CI and BNP (Spearman: − 0.12; p value = 0.35). Conclusion Increasing use of ultrasound has led to innovative techniques for estimating volume status. While prior ultrasound studies have used clinical parameters to estimate fluid status, our study used RHC measurements and demonstrated that compression CI potentially reflects directly measured mRAP and PAOP.

In a former communication we incidentally mentioned that in a rabbit killed by the injection of cobra-poison into the jugular vein we had observed the pulmonary vein pulsating after all motion had ceased in the cavities of the heart. We have since observed the same phenomenon three or four times under conditions which show that this pulsation is not due to the action of the cobra-poison with which the animal in which we first observed it had been killed. The following example will show the changes in rhythm observed in these pulsations. A cat was chloroformed, and the vagi exposed and irritated by an interrupted current. Artificial respiration was kept up by air containing chloroform vapour, and the thorax was then opened, and a solution of atropia injected directly into the heart by means of a Wood’s syringe. The vagi were again irritated, but without any effect being produced on the heart, the inhibitory apparatus in it being evidently paralyzed by the atropia. A solution of glycerine extract of physostigma was now injected into the heart in a similar way. The vagi were now irritated again, and the heart stood still, the effect of the atropia having been counteracted by the physostigma. After the irritation ceased the heart again commenced to pulsate.

Abstract Introduction Device related complications are rising the need of Transvenous Lead Removal (TLR). Transvenous extraction of Pacing (PL) and Defibrillating Leads (DL) is a highly effective technique. Aim of this report is to analyse the longstanding experience performed in a single Italian Referral Center. Methods Since January 1997 to December 2019, we managed 2769 consecutive patients (2100 men, mean age 65.5 years) with 5086 leads (mean pacing period 73.6 months, range 1–576). PL were 3998 (1828 ventricular, 1704 atrial, 466 coronary sinus leads), DL were 1088 (1067 ventricular, 6 atrial, 15 superior vena cava leads). Indications to TLR were infection in 79% (systemic 27%, local 52%) of leads. We performed mechanical dilatation using a single polypropylene sheath technique and if necessary, other intravascular tools; an Approach through the Internal Jugular Vein (JA) was performed in case of free-floating leads or failure of the standard approach. Results Removal was attempted in 5076 leads because the technique was not applicable in 10 PL. Among these, 4952 leads were completely removed (97.6%), 49 (1.0%) partially removed, 75 (1.4%) not removed. Among 4989 exposed leads, 818 were removed by manual traction (16.4%), 3664 by mechanical dilatation using the venous entry site (73.4%), 48 by femoral approach (FA) (1.0%) and 335 by JA (6.7%). All the free-floating leads were completely removed, 25.3% by FA and 74.7% by JA. Major complications occurred in 20 cases (0.72%): cardiac tamponade (19 cases, 4 deaths), hemotorax (1 death). Conclusions Our experience shows that in centers with wide experience, TLR using single sheath mechanical dilatation has a high success rate and a very low incidence of serious complications. TLR through the Internal Jugular Vein increases the effectiveness and safety of the procedure also in case of free-floating or challenging leads. Funding Acknowledgement Type of funding source: None

A persistent left superior vena cava (PLSVC) is a congenital anomaly of the systemic venous system. This anomaly is often discovered as an incidental result during central venous catheterization passing through the left subclavian or the left internal jugular vein. We report two cases of PLSVC in pediatric patients.
