Improvement of Capillary Permeability in Patients with Venous Hypertension After Treatment with TTFCA

Angiology, 1990
The VSC (vacuum suction chamber) device, a new system to evaluate local capillary permeability, was used with laser Doppler flowmetry to study varia tions of permeability and of the microcirculation in 10 normal subjects; in 22 patients with moderate, superficial venous hypertension; and in 12 patients with postphlebitic limbs and severe venous ...

Venous occlusion pressure and vascular permeability in the dog lung after air embolization

Journal of Applied Physiology, 1988
Pulmonary edema has frequently been associated with air embolization of the lung. In the present study the hemodynamic effects of air emboli (AE) were studied in the isolated mechanically ventilated canine right lower lung lobe (RLL), pump perfused at a constant blood flow. Air was infused via the pulmonary artery (n = 7) at 0.6 ml/min until pulmonary

Diapedesis and the permeability of venous microvessels to protein macromolecules: The impact of leukotriene B4 (LTB4)

Microvascular Research, 1988
The cellular basis of the reported neutrophil-dependent increase in microvascular permeability evoked by leukotriene B4 (LTB4) was probed using protein intravascular fluorescent and electron dense tracers in conjunction with intravital, light and electron microscopy. LTB4 (1 microM) applied topically to the hamster cheek pouch promoted neutrophil (PMN)

Continuous arterio-venous haemodiafiltration: hydraulic and diffusive permeability index of an AN-69 capillary haemofilter

Medical and Biological Engineering and Computing, 1998
The dependence of uraemic solute clearance on the hydraulic and diffusive permeability index of an AN-69 capillary haemofilter is investigated during the treatment of patients with continuous arterio-venous haemodiafiltration (CAVHD). A mathematical model is presented to calculate solute clearance and the hydraulic and diffusive permeability index ...

Increased microvascular water permeability in patients with septic shock, assessed with venous congestion plethysmography (VCP)

Intensive Care Medicine, 1998
To investigate microvascular water permeability (filtration capacity, Kf) in patients with septic and non-septic shock using a new non-invasive method for studying microvascular parameters in man.Intensive Care Unit of a university hospital.We investigated 28 patients, presenting with cardio-vascular instability due to either septic shock, or non ...

Permeability pulmonary edema caused by venous air embolism.

The American review of respiratory disease, 1984
A 22-yr-old man developed severe pulmonary edema after blowing air into tubing connected to a catheter inserted in a vein in his forearm. Pulmonary edema was rapid in onset, peaking in intensity about 12 h after the air had been insufflated. The patient's edema fluid to plasma protein concentration ratio of 0.79 showed that the edema fluid was rich in ...

[Permeability of venous aortocoronary bypass 5 years later].

Archives des maladies du coeur et des vaisseaux, 1979
47 consecutive patients who had undergone aorto-coronary venous bypass surgery (mean: 1.6 graft per patient) have been investigated after a mean follow-up period of 5 years and 9 months (range: 44-108 months). 52 grafts out of 73 were found to be patent (71 p. 100), the best patency rate being shown by grafts on the LAD artery (27/32 = 85 p. 100). Long-

Microvascular permeability, venous stasis and oedema.

International angiology : a journal of the International Union of Angiology, 1990
Microvascular permeability to fluid and hydrophilic solutes is restricted to channels between the endothelial cells and through the fenestrations when these are present. The channels have a molecular filter which appears to be a lattice of fibrous molecules reinforced by plasma proteins.

[Permeability of venous aortocoronary bypasses one year after their implantation].

Archives des maladies du coeur et des vaisseaux, 1987
For a short-term evaluation of the patency of aortocoronary bypass vein grafts, 54 consecutive patients who underwent this operation alone were examined, irrespective of their functional state, 12.4 +/- 2.1 months after surgery. Examinations included coronary arteriography, selective opacification of the graft and ventriculography. The patients were 47

Permeability of human venous endothelial cell monolayers perfused in microcarrier cultures: Effects of flow rate, thrombin, and cytochalasin D

Journal of Cellular Physiology, 1991
AbstractWe have applied a multiple isotope dilution technique to examine junctional permeability of human umbilical vein endothelial cells (HUVEC) in vitro. Primary cultures were grown to confluence on porous Cytodex‐3 microcarrier beads, packed into 0.3 ml columns (3 × 106 cells) and perfused at varying flow rates (0.3–1.2 ml/min) with HEPES‐buffered ...
