Absence of the Right Pulmonary Artery Associated With a Partial Anomalous Pulmonary Venous Connection

Unilateral absence of a pulmonary artery is a rare anomaly. Patients may present with hemoptysis, recurrent respiratory infections, pulmonary hypertension, or congestive heart failure. This report describes the case of a missing right pulmonary artery associated with anomalous left pulmonary venous connection not previously described in the medical literature.

Early initiation of peritoneal dialysis after arterial switch operations in newborn patients.

Background and aim: We investigated the clinical outcome of early initiated peritoneal dialysis (PD) use in our newborn patients who underwent arterial switch operation (ASO) for transposition of the great arteries (TGA) and had routine intraoperative PD catheter implantation. We determined the risk factors for PD, factors associated with prolonged PD, morbidity, and mortality. The aim of the present study was to describe our experience of using PD in this patient cohort. Materials and Methods: Eighty two patients who were diagnosed with TGA and TGA-ventricular septal defect (VSD) and who had undergone TGA correction operation in Başkent University, Istanbul Medical Research and Training Hospital between 2007 and 2012 were retrospectively investigated. All the patients were under 30 days old. PD catheters were routinely implanted intraoperatively at the end of the operation. PD was initiated in transient renal insufficiency. In the absence of oliguria and increased creatinine level, PD was established in the presence of one of the following: clinical signs of fluid overload, hyperkalemia (>5 mEq/L), persistent metabolic acidosis, lactate level above 8 mmol/L or low cardiac output syndrome. The patients were divided into two groups according to the need for postoperative PD (PD group and non-PD group). PD was initiated in 32 (39%) patients after the operation, whereas 50 (61%) patients did not need dialysis. The clinical outcomes and perioperative data of the two groups were compared. Results: The demographics in the two groups were similar. Cardiopulmonary bypass time was longer in the PD group [non-PD group, 175.24 ± 32.39 min; PD group, 196.22 ± 44.04 min (p < 0.05)]. Coronary anomaly was found to be higher in the PD group [non-PD group, n = 2 patients (4.0%); PD group, n = 7 patients (21.9%); p < 0.05]. There was more need for PD in TGA + VSD patients [simple TGA patients, n = 14; TGA + VSD patients, n = 18 (p < 0.05)]. PD rate was higher in patients whose sterna were left open at the end of the operation (p < 0.05). The ventilator time [non-PD group, 4.04 ± 1.51 days; PD group, 8.12 ± 5.21 days (p < 0.01)], intensive care unit stay time [non-PD group, 7.98 ± 5.80 days; PD group, 15.93 ± 18.31 days (p < 0.01)], and hospital stay time were significantly longer in the PD group [non-PD group, 14.98 ± 10.14 days; PD group, 22.84 ± 20.87 days (p < 0.01)]. Conclusion: We advocate routine implantation of PD catheters to patients with TGA-VSD, coronary artery anomaly, and open sternum in which we have determined high rate of postoperative PD need.

Le-Compte maneuver in surgical correction of absent pulmonary valve. Does it improve severe bronchial compression?

Here,we present a case of absent pulmonary valve syndrome operated with Le-Compte maneuver. Although Le-Compte maneuver was performed, endobronshial stent placement was carried out in order to relieve the airway obstruction.

Crisscross heart with tricuspid atresia diagnosed in utero.

Crisscross heart is a rare congenital cardiac anomaly in which systemic and pulmonary venous streams cross without mixing at atrioventricular level. We report a case of crisscross heart with tricuspid atresia, double outlet right ventricle, and pulmonary stenosis, which was diagnosed prenatally.

[Follow-up of our patients with transposition of the great arteries and arterial switch operation; comparison of simple and complex transposition cases].

OBJECTIVE 1. Follow-up data of patients with simple transposition of great arteries (TGA) and TGA with ventricular septal defect (VSD), who had arterial switch operation (ASO) are compared. 2. Factors affecting mortality and morbidity after ASO are described. METHODS Seventy-six patients, who had an ASO between April 2007 and August 2010 were studied retrospectively. The patients with intact ventricular septum (IVS) (n=36) were in Group 1, and those with VSD (n=40) in Group 2. The pre and postoperative clinical and echocardiographic variables and intensive care unit (ICU) outcomes were compared among groups using Mann-Whitney U, Pearson correlation and logistic regression tests. RESULTS The mean age at operation was 44.1 days, weight was 3.6±0.98 kg. Patients were followed for 15.5±11.21 months. The aortic cross-clamp (AoCC) and cardiopulmonary bypass (CPB) times were higher in patients with VSD (p=0.001, p=0.004). Patients in Group 1 had longer inotropic agent infusion (p=0.001). Length of stay in ICU was similar in two groups (p>0.05). There was no correlation between the length of stay in ICU and age, weight, CPB time, AoCC time. Aortic regurgitation was more frequent in Group 2 (p=0.02). During follow-up, 12 patients died (15.7%), and 8 patients had a revision operation (10.5%) (diaphragmatic plication in 4, pulmonary artery reconstruction in 1, recoarctation operation in 3 patients). Mortality was similar in groups (p>0.05). CONCLUSION Arterial switch operation provides anatomical correction in TGA. Appropriate timing and good perioperative planning facilitates low morbidity and mortality in patients with VSD as in patients with simple TGA.
