The role of postabsorptive mechanisms in long-term control of drinking behavior, Na+ balance, and arterial pressure was examined in Dahl salt-sensitive (DS) and salt-resistant (DR) rats. NaCl (0.15 M) was infused (0.5 ml/h) into either the inferior vena cava (IVC) or the portal vein (PV) for 7 days, and then 1.5 M NaCl was infused for 10 days. During 1.5 M infusion, the IVC group retained more Na+ than the PV group. Furthermore, in DS rats, mean arterial pressure was higher in the IVC group than in the PV group. Regardless of the strain and infusion route, 1.5 M infusion had no effect on volume of daily saline consumption. However, when the data for light and dark periods were analyzed separately, dark period saline consumption in the PV group was decreased by 1.5 M infusion but was not changed in the IVC group. These results indicate that, in Dahl rats, the postabsorptive mechanism plays a significant role in controlling long-term saline drinking behavior and Na+ balance and has a significant role in controlling arterial pressure in DS, but not DR, rats.

Abstract Purpose of review Describe the role of inferior vena cava filter (IVCF) retrieval in patients on chronic anticoagulation given the overlap of these treatment options in the management of patients with venous thromboembolic disease. Recent findings Despite the increase in IVCF retrievals since the Food and Drug Administration safety communications in 2010 and 2014, retrieval rates remain low. Previous studies have shown that longer filter dwell times are associated with greater risk for filter complications and more difficulty with filter retrievals. Recent findings suggest that complications are more frequent in the first 30 days after placement. Summary The decision to retrieve an optional IVCF is individualized and requires diligent follow-up with consistent re-evaluation of the need for the indwelling IVCF, particularly in those on long-term anticoagulation therapy.

Background: Spinal anesthesia has become an alternative to general anesthesia. However, spinal anesthesia has the most common side effects including, bradycardia and hypotension. The aim of this study was to determine the relationship between changes in the inferior vena cava index (delta inferior vena cava index) to changes in mean arterial pressure in spinal anesthesia. Methods: This study was an observational pre-post test study in thirty-two patients who received spinal anesthesia. The inferior vena cava index (inferior vena cava collectibility index and caval-aorta index) was measured before and after spinal anesthesia (5 and 10 minutes after onset). Data were analyzed using the Kolmogorov Smirnov test, Shapiro-Wilk test, T-test, and correlation test with α=5% Result: There was a significant difference in mean arterial pressure (MAP), delta inferior vena cava collectibility index (D-IVC-CI), and delta caval-aorta index (D-CAo-I) before and after spinal anesthesia. D-IVC-CI and D-CAo-I are significantly correlated with MAP. The correlation between D-IVC-CI and MAP had R = -0.371 (P <0.05) at 5 minutes post-anesthesia, while D-CAo-I and MAP had R = 0.472 (P <0.05) at 10 minutes post-anesthesia. Conclusion: The delta inferior vena cava index is correlated with the mean arterial pressure (MAP) value in spinal anesthesia.

Objective The Simon Nitinol filter is a bi-level filtration device designed for permanent implantation that is no longer commercially available, but may result in similar complications to current commercially available long term indwelling temporary or permanent filters. Complications related to indwelling inferior vena cava filters include inferior vena cava thrombosis, inferior vena cava penetration, filter migration, and filter fracture. There is a paucity of reports describing the technical aspects related to retrieval of Simon Nitinol filters. Materials and methods This study consisted of five patients with Simon Nitinol filters and describes the indication for retrieval, the retrieval techniques used to remove the filters, technical success, complications, and clinical course. Results The indications for retrieval included: abdominal pain ( n = 2; 40%), iliocaval thrombosis ( n = 1; 20%), identification of an intracardiac filter fragment ( n = 1; 20%), and recurrent venous thromboembolic events ( n = 1; 20%). Retrieval techniques included: biopsy forceps ( n = 3; 60%), excimer laser extraction sheaths ( n = 3; 60%), hangman modified loop snares ( n = 3; 60%), rigid endobronchial forceps ( n = 2; 40%), and balloon deflection ( n = 2; 40%). All filters were successfully retrieved. One patient developed a post-procedural intramuscular hematoma near the site of right internal jugular sheath placement. Conclusions Simon Nitinol filters may be retrieved safely and effectively using advanced inferior vena cava filter retrieval techniques.
