Proliferation And Migration

Objective To investigate the biological effects of a novel endovenous scaffold in a porcine model. Methods Petalo is a compliant venous scaffold implanted into the internal jugular veins of 12 healthy pigs. The pigs were sacrificed at one, two, three, and six months, respectively. Microscopic investigations were performed at two blinded laboratories. Results Neo-intima formation progressively covering up the stent metallic bars was observed. The inflammatory response of the venous wall showed a peak after three months by the implant, followed by marked reduction after six months. The device induced a significant ( p < 0.01) increase of the thickness respect to the control regions, but was comparable in sections obtained after three and six months. Conclusions The implant of Petalo compliant venous scaffold in the venous wall of this porcine model is characterized by neointima formation and by an inflammatory reaction which tends to decrease after six months. Our data point against the induction of smooth muscle cells proliferation and migration as confirmed by electronic transmission microscopy analyses.

A simple pressure-based technique for the detection of venous obstruction is described. The severity of obstruction can be graded utilizing the technique outlined. The method has a high degree of sensitivity and specificity and is easily employed as a routine procedure in the vascular laboratory. The technique provides invaluable haemodynamic information in venous obstruction in a variety of clinical settings as illustrated.

Diagnostic Modalities

Iliac venous outflow obstruction has an important role in the expression of symptomatic chronic venous insufficiency. This anatomic obstruction is frequently overlooked, owing in part to diagnostic difficulty. The combination of venous obstruction and reflux leads to more severe clinical disease. Current diagnostic modalities do not allow an definitive assessment of hemodynamically critical venous obstruction. No single invasive or noninvasive study can accurately detect borderline obstruction of potential hemodynamic significance. A high index of suspicion is critical in the initial recognition of chronic venous obstruction. The diagnosis relies on clinical signs and symptoms and radiologic assessment of morphologic venous outflow obstruction. Treatment strategy should be based on the results of morphologic investigations such as transfemoral phlebography or, preferably, intravascular ultrasonography. Percutaneous iliac venous stenting offers a safe and efficient method to correct pelvic venous obstruction. Percutaneous iliac stenting does not preclude subsequent venous bypass or corrective superficial and deep reflux surgery. This article reviews the etiologic factors and diagnostic modalities of iliac venous obstruction. The therapeutic role of percutaneous iliac stenting in the management of venous obstruction is also discussed.

Valve Function

The advent of duplex ultrasound (DU) has changed vascular practice over the years. Venous anatomy, valve function and obstruction can be evaluated in real time using DU. It is a low cost, portable, non-invasive, safe and operator-friendly device that can be used for diagnosis, treatment guidance and follow-up. This paper defines the patterns, location and characteristics of venous reflux and also provides insightful information on acute and chronic venous obstruction.

Chronic Venous Obstruction

This consensus statement of Russian experts is based on a review of the relevant literature on the prevalence, diagnosis, and treatment of non-thrombotic and post-thrombotic venous obstruction, as well as management of patients after venous stenting. In the Part 1 we discussed the clinical manifestations of venous obstruction, the role of duplex ultrasound scan, CT venography, MR venography, direct venography, and intravascular ultrasound scan, as well as typical findings obtained by using these methods. The authors mentioned the functional assessment of venous outflow in healthy subjects and in those with obstruction and changes in them after the intervention. In conclusion, the authors formulated the suggestions for clinical recommendations on the diagnosis of chronic venous obstruction.
