Anomalous origin of one pulmonary artery branch from ascending aorta ("so-called hemitruncus"): report of an additional case treated surgically.

The aortic origin of one pulmonary artery branch, so-called hemitruncus, is a rare congenital anomaly with poor prognosis. In this report, an additional patient is presented. The patient, a 60-day-old male infant with the right pulmonary artery originating from the ascending aorta was operated successfully. Postoperative catheterization demonstrated normal flow to the right lung and pulmonary artery pressure decreased to normal level.

Correction of truncus arteriosus using a fresh autologous pericardial trileaflet valve conduit.

A fresh autologous pericardial trileaflet valve conduit was used in a 5-month-old infant for correction of truncus arteriosus. The patient recovered from the operation with satisfactory hemodynamics and post-operative echocardiogram at 3 months showed only mild to moderate pulmonary regurgitation. This technique is a useful alternative for correction in an infant with congenital heart disease who needs a tissue valve conduit. It may be more suitable than an aortic homograft by reason of unavailability of small homograft and limitation of organ donation.

[Roentgenosurgery for aortic coarctation and open arterial duct with intravascular ultrasonic examination].

Forty-five patients (32 with open arterial duct and 13 with aortic coarctation) were examined. Forty-nine intravascular ultrasonic examinations were performed, qualitative and quantitative analysis of 139 vascular segments was carried out. Despite the fact that mean morphometric indices of open arterial duct and aorta in angiography and intravascular ultrasonic examination had no significant difference, real confidence of the o data was seen only in 13.3% cases for open arterial duct an in 16.7% cases--for aortic coarctation. In 37.5 and 50% patients, respectively, difference in the dimensions was so significant that dictated choice of instruments with difference size. Roentgenoendovascular surgeries were performed in 23 patients with open arterial duct and in 12--with aortic coarctation. Choice of instruments parameters based on data of intravascular ultrasonic examination provided safer and more efficient procedures.
