Inferior Vena Cava Obstruction

Complete superior vena cava (SVC) and inferior vena cava (IVC) obstruction is not uncommon and most commonly associated with malignancy. The risk increases in patients with central lines and hypercoagulable states such as with malignancy, thrombophilia, or use of oral contraceptive pills. According to our knowledge, complete SVC and IVC obstruction associated with systemic-to-pulmonary venous shunts in patients with prothrombin G20210A gene mutation has not been reported in the literature. Here we report the case of a 34-year-old female with complete SVC and IVC obstruction presenting with oxygen desaturation and shortness of breath due to systemic-to-pulmonary venous shunts. The unusual collateral pathway was secondary to SVC obstruction. The patient was managed conservatively, and she remained stable.

Abstract Background Transseptal puncture and pulmonary vein isolation (PVI) in patients with atrial fibrillation (AF) are generally performed via the inferior vena cava (IVC). However, in cases where the IVC is inaccessible, a specific strategy may be needed. Case summary An 86-year-old woman with paroxysmal AF and an IVC filter in situ was referred to our hospital for ablation therapy. An IVC filter for pulmonary embolism and deep venous thrombosis had been implanted 15 years prior, therefore we selected a transoesophageal echocardiography (TOE)-guided transseptal puncture using a superior vena cava (SVC) approach. After the single transseptal puncture, we performed fast anatomical mapping, voltage mapping by multipolar mapping catheter, and then PVI by contact force-guided radiofrequency catheter using a steerable sheath. Following the ablation, bidirectional conduction block between the four pulmonary veins and the left atrium was confirmed by both radiofrequency and mapping catheter. No complications occurred and no recurrence of AF was documented in the 12 months after the procedure. Discussion When performing a transseptal puncture during AF ablation, an SVC approach, via access through the right internal jugular vein, enables the sheath to directly approach the left atrium without angulation and improves operability of the ablation catheter. Combining the use of general anaesthesia, TOE, a steerable sheath, and contact force-guided ablation may contribute to achieving minimally invasive PVI with a single transseptal puncture via an SVC approach.

Venous Cannula

A method for the detection of vena caval contamination in blood taken from hepatic venous cannulas in conscious rats was described. The procedures included 1) bolus injection of tritiated water (50 microCi) through a cannula into the abdominal inferior vena cava and 2) continuous blood sampling (less than 0.2 ml) from the hepatic venous cannula for 2 min into a 180-cm piece of Tygon tubing, starting concurrently with tracer injection. The washout of tritium was determined from samples in 15-cm sections of Tygon tubing. Because circulation from the inferior vena cava to the hepatic vein is interceded by the systemic circulation, the washout of tritium from a valid hepatic venous cannula should resemble the pattern determined elsewhere in the systemic circulation. In the current study, the reference systemic washout was determined in the superior vena cava of a group of rats similarly injected with tritiated water in the inferior vena cava. The maximum of tritium washout derived from a valid hepatic venous cannula should fall in the range encompassed by one standard deviation of the mean of the maximum of the reference (1,400 to 1,930 cpm/sample). The maximum of the washout pattern derived from the invalid cannula, which lay adjacent to the site of injection, was expected to exceed this range. On the basis of these criteria, hepatic blood flow (HBF) was determined by sulfbromophthalein (BSP) extraction in groups of rats with valid and invalid cannulas. HBF in rats with valid hepatic venous cannulas was 2.58 +/- 0.15 in the conscious state and 2.76 +/- 0.26 ml.min-1.g wet wt-1 in the ketamine-anesthetized state.(ABSTRACT TRUNCATED AT 250 WORDS)

Vena Cava Syndrome

Background. In the superior vena cava syndrome, vein catheterisation provides an alternative for vascular access. Few reports describe the usage of femoral ports.Aim. Description of pros and contras for femoral port installation in patients with haematological malignancies and the superior vena cava syndrome.Materials and methods. This prospective non-randomised, single-centre study included 163 haematological patients implanted 72 ports in superior vena cava, 35 — in inferior vena cava and inserted with 156 non-tunnelled femoral catheters. Catheterisation properties, complications, duration of use and reasons for port and catheter removal were registered.Results. No significant differences were observed between ports in superior and inferior vena cava as per the frequency of urokinase use in catheter dysfunction, catheter dislocation, catheter-associated bloodstream and pocket infections. Differences were revealed in the catheter-associated thrombosis rate, which was higher with femoral access (17.0 % or 0.9/1000 catheter days vs. 8.3 % or 0.2/1000 catheter days, p = 0.017). Ports in inferior vena cava had a lesser duration of use than in superior vena cava (p = 0.0001). Unlike femoral ports, non-tunnelled femoral catheters had higher rates of catheter-associated thrombosis (9/1000 vs. 0.9/1000 catheter days, p = 0.002) and infection (4.9/1000 vs. 0.3/1000 catheter days, p = 0.002). One lymphoma therapy course required one femoral port or 1 to 14 (median 3) non-tunnelled femoral catheters.Conclusion. Femoral port implantation is a necessary measure in patients with the superior vena cava syndrome. It has advantages in terms of catheterisation frequency, lower infectious and thrombotic complication rates compared to non-tunnelled femoral catheters.
