Superior vena cava (SVC) and inferior vena cava (IVC) pressures were measured serially during laparoscopic cholecystectomy in which the intra-abdominal pressure was maintained at 12mmHg. The influences of alteration of position from 15 degrees head-down to 15 degrees head-up and of the operative procedure of holding the gallbladder up to the right subphrenic space on SVC and IVC pressures were mild. IVC pressure was maintained almost equal to the intra-abdominal pressure during prolonged continuous pneumoperitoneum lasting longer than 60min, while SVC pressure did not change significantly during operation. The discrepancy between SVC and IVC pressures underwent no change during continuous pneumoperitoneum.

Anomalous vena cavae can have significant implications for procedures on the right side of the heart. We report a rare anatomical configuration in a 44-year-old female, which to the best of our knowledge, is the first report of such an association. She had a bicuspid aortic valve in conjunction with a persistent left superior vena cava (PLSVC) draining into the coronary sinus, and a left-sided inferior vena cava (IVC) draining into a left superior vena cava via the hemiazygos vein. Comprehensive assessment of these anomalies is crucial given the widespread use of invasive cardiac procedures.

Cavopulmonary Shunt

The left superior vena cava became occluded in an infant with hypoplastic left heart syndrome. After a bidirectional Glenn procedure, he presented with severe oxygen desaturation and right ventricular dysfunction; the left superior vena cava drained into the inferior vena cava through collateral veins. As salvage therapy, we created a modified total cavopulmonary shunt using only autologous tissue in which the right hepatic vein and inferior vena cava drained into the pulmonary artery via a lateral tunnel in the right atrium. Immediately after surgery, his oxygen saturation increased and right ventricular function improved.

Background & Objectives: To evaluate the advantages of the one and a half ventricle repair on maintaining a low pressure in the inferior vena cava district. Also evaluate the competition of flows at the superior vena cava – right pulmonary artery anastomosis site, in order to understand the hemodynamic interaction of a pulsatile flow in combination to a laminar one. Materials & Methods: Adult rabbits (n=30) in terminal anaesthesia with a follow up of 8 h were used, randomly distributed in three experimental groups: Group 1: animals with an anastomosis between superior vena cava and right pulmonary artery, as a model of one and one half ventricle repair; Group 2: animals with the cavopulmonary anastomosis followed by clamping of the right pulmonary artery proximal to the anastomosis; and Group 3: sham animals. Pressures of superior vena cava and pulmonary arteries were afterwards measured, in a resting condition as well as after induced pharmacological stress test.Results: In Group 1, superior vena cava pressure was significantly higher, while venous pressure in the inferior vena cava – right atrium district was constant or lower in comparison with the other groups. After stress test, the pressure in the superior vena cava and the heart rate both increased further, but the right ventricular, right atrial and pulmonary artery pressures remained similar to the values in a resting condition. This proved that the inferior vena cava return was well-preserved, and no venous hypertension was present in the inferior vena cava district even after stress test (good exercise tolerance).Conclusion: One and one half ventricle repair can be considered a good surgical strategy for maintaining a low pressure in the inferior vena cava district with potential for right ventricle growth, restoring the more physiological circulation in borderline or failing right ventricle conditions. The experiment presented a positive finding in favour of one and one half ventricle repair, as compared to Fontan type procedure.

Venous stent placement of symptomatic occlusion of the superior and inferior vena cava is considered the treatment of choice in malignant disease because this technique can restore patency and achieve a relief of symptoms. However, tumor thrombus extension into the right atrium harbors the potential risk of stent migration and perforation. One strategy to avoid this potential life-threatening complication could be the placement of a bridging stent from the superior vena cava-to-inferior vena cava. This case reports describes the superior vena cava-to-inferior vena cava bridging stent technique in 2 patients with malignant occlusion of the superior and inferior vena cava. Special considerations such as technical details of the devices and potential complications are discussed.

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.
