Grading abdominal aortic aneurysm rupture risk.

Background: The aim of this paper was to develop a scoring system to grade the risk of rupture of an abdominal aortic aneurysm (AAA) in individual patients.

Methods: Computed tomography angiography of an AAA were coupled with computational fluid dynamics (CFD) evaluation performed using open source software (ElmerSolver, Institute of Technology, Espoo, Finland). CFD criteria studied were: Oscillatory Shear Index (OSI), time averaged wall shear stress (TAWSS) and residence relative time (RRT) on both two-dimensional (2D) and three-dimensional (3D) models.

The immediate effects of endovenous diode 808-nm laser in the greater saphenous vein: morphologic study and clinical implications.

Background: We conducted this study to evaluate the immediate venous morphologic alterations produced in the great saphenous veins by the endovenous diode 808-nm laser used for the treatment of superficial venous insufficiency and varicose veins of the lower limbs and to clarify the clinical implications of the histologic findings.

Methods: Chosen for the study were 24 limbs of 16 patients with CEAP classification 3 to 6, ultrasound-documented greater saphenous insufficiency, and venous diameters between 3.9 mm and 17 mm (mean, 8.

A new autologous venous valve by intimal flap. One case report.

Various surgical techniques have been proposed for the treatment of chronic venous insufficiency of post-thrombotic recanalized deep veins of the lower limbs. The preferable method seems to be represented by intravenous valvuloplasty except for the cases affected by extensive valvular damage. For this reason some experimental autologous, heterologous and prosthetic venous valves have been proposed.

Reparative surgery of valves in the treatment of superficial venous insufficiency. External banding valvuloplasty versus high ligation or disconnection. A prospective multicentric trial.

Objective: A prospective study was performed in order to compare results obtained in the treatment of early and/or limited primary varicose veins of the lower limbs using two different procedures: external valvuloplasty and high ligation or disconnection of the sapheno-femoral junction.

Materials And Methods: 116 limbs (113 patients) were selected. 57 with normal cusps in dilated valves were subjected to external valvuloplasty with Silicone prosthesis under Doppler control (intraoperative angioscopy in 16 cases); 59 limbs were subjected to high ligation or disconnection of the junction; 57 limbs out of 116 were subjected to complementary procedures.

Sapheno-femoral valves. Histopathological observations and diagnostic approach before surgery.

Background: Since the literature indicated that in the early stages of primary venous disease valves are simply dilated, some authors performed external valvuloplasty of deep and superficial venous valves with encouraging results, although some failures were observed without being sufficiently explained.

Objective: To obtain further interpretations of the natural history of venous valve pathology, clarify methods for a correct diagnostic approach, and provide indications for the external valvuloplasty procedure.

Methods: Forty-two proximal valves of the long saphenous vein removed for varicose veins of the lower limbs were studied with optical microscopy.
