Off-Pump Plicating Ascending Aortoplasty With External Wrapping: Magnum in Parvo.

Background: Isolated, fusiform aneurysms, exclusively affecting the tubular portion of the ascending aorta, are rare. Surgical treatment aims to change their natural course, reducing individual and cumulative risks of rupture, dissection and death. Open tubular graft replacement still remains the procedure of choice, despite significant risks.

[Effect of hypertonic-hyperoncotic solution infusion on tissue perfusion during surgical treatment of the abdominal aorta].

Background/aim: Decreasing of arterial flow below the critical level leads to capillary endothelium edema and to further worsening of tissue perfusion. Hypertonic solution infusion provides mild and short plasma osmolality increasing, while colloidal solutions intensify that effect. The aim of this study was to investigate the effect of hypertonic-hyperoncotic solution (HH) on the organs perfusion during reconstructive surgical procedure on the abdominal aorta (AA).

[Effect of infusion of hypertonic-hyperoncotic solution on cardiovascular function in surgery of the abdominal aorta during the perioperative period].

Introduction: When blood flow is decreased, as in prolonged hypovolaemia and hypotension, or in the course of transversal clamping of the aorta during aortic reconstruction, nutritive tissue perfusion can also fall below the critical level.

Aim: The objective of this study was to analyse the effects of hypertonic-hyperoncotic solution on cardiovascular function during reconstruction of the abdominal aorta.

Method: This prospective randomised study included 40 patients.

Adenosine cardioprotection study in clinical setting of paroxysmal supraventricular tachycardia.

PSVT attack of >20min and frequency >160 is well-recognized model of myocardial dysfunction. We measured 6-keto-PGF1alpha and TXB(2) before and after adenosine administration to assess its cardioprotective potential. A total of 64 patients were randomly assigned as having acute episode of PSVT to adenosine or verapamil group.
