    Notes: Summary Surgical patients develop a fluid deficit during pre-operative starvation. This study examines the effects of pre-operative fluid administration on haemodynamic variables, oxygenation and splanchnic perfusion in patients undergoing elective coronary artery bypass grafting. Forty-eight patients were randomised to receive either a pre-operative crystalloid infusion (crystalloid group, n = 24) or no infusion (control group, n = 24). Patients in the crystalloid group received a continuous infusion of Ringer's solution at 1.5 ml.kg−1.h−1 from 22:00 h until induction of anaesthesia the next morning. Immediately before induction of anaesthesia, all patients were given a colloid infusion to increase pulmonary capillary wedge pressure and central venous pressure to similar levels inboth groups. Haemodynamic and oxygenation parameters were measured using invasive cardiovascular monitoring, and splanchnic perfusion was assessed by indocyanine green clearance. Patients in the crystalloid group received a mean (SD) of 1008 (140) ml of Ringer's solution overnight. Patients in the crystalloid group had a higher splanchnic blood flow than the control group before induction of anaesthesia [mean (SD) = 1782 (573) ml.min−1 vs. 1391 (333) ml.min−1, p 〈 0.05]. There were no significant differences in systemic haemodynamic data and global oxygenation parameters between the two groups. Pre-operative infusion of crystalloid appears to result in an improvement in pre-operative splanchnic perfusion.

    Notes: Abstract. Mycotic pseudoaneurysm of the aorta is a rare disease in childhood. We report on two cases which were diagnosed in an unselected general pediatric population within an 8-month period. The first case was a 16-month-old toddler with a normal cardiac history who presented with purulent pericarditis due to group A steptococcus and subsequent pseudoaneurysm formation of the ascending aorta while convalescing from varicella infection. The second case was a 14-year-old girl with a previously undiagnosed coarctation of the aorta who developed a Staphylococcus aureus aortitis in the dilatated poststenotic segment with pseudoaneurysm formation and infiltration into the adjacent lung tissue. In both cases parenteral antibiotic therapy was administered over 10 and 4 days, respectively, followed by emergency surgery consisting of aneurysmectomy, coarctectomy (case 2), and in situ homograft implantation. Recovery was uneventful. In both cases early institution of a femorofemoral cardiopulmonary bypass prevented a fatal outcome despite intraoperative rupture of the pseudoaneurysm.

    Description / Table of Contents: Zusammenfassung Im Rahmen von Palliativoperationen kongenitaler Herzfehler mit Etablierung einer Fontanzirkulation ist die präoperative Diagnostik der systemvenösen Anatomie von besonderer Bedeutung. Präexistierende Varianten, wie die linkspersistierende obere Hohlvene, kommen bei kongenitalen Herzfehlern gehäuft vor und können postoperativ für Zyanose und Herzinsuffizienz verantwortlich werden. Wir beschreiben einen 6 Monate alten Patienten mit einem imbalancierten atrioventrikulären Septumdefekt, bei dem sich nach Anlage einer bidirektionalen cavopulmonalen Konnektion in der frühpostoperativen Phase eine ausgeprägte Zyanose entwickelte. Als ursächlich für eine ineffektive Lungenperfusion konnte die Wiedereröffnung einer linkspersistierenden oberen Hohlvene mit Drainage in den Sinus coronarius diagnostiziert werden. Durch Coilembolisation mittels replazierbarer Metallspiralen konnte das Lumen der linken oberen Hohlvene effektiv verschlossen werden. Die Zyanose besserte sich unmittelbar. Eine Coilembolisation stellt eine effektive Alternative zu einem chirurgischen Reeingriff dar, insbesondere bei postoperativ hämodynamisch instabilen Patienten.
    Notes: Summary Diagnosis of systemic venous drainage is mandatory for patients with congenital heart disease planned for cavopulmonary anastomosis or any Fontan-type palliation. Preexisting venous channels as the persistent left superior vena cava are common in cardiac anomalies and may lead to postoperative deterioration and cyanosis. We describe a 6 month old boy with a complex imbalanced atrioventricular septal defect who developed cyanosis in the very early postoperative period, following bidirectional cavopulmonary anastomosis. It was caused by ineffective lung perfusion due to a reopened persistent left superior vena cava with drainage to the coronay sinus. He underwent coil embolization of the persistent left superior vena cava with retrievable coils and cyanosis improved. Coil embolization is an effective alternative to secondary surgery, especially for hemodynamically compromised patients in the postoperative period.
