Abstract

The occurrence of ischaemic changes, arterial occlusion, and other complications which may follow percutaneous arterial cannulation was assessed in a survey of 155 patients. No patient complained of or had signs of ischaemic damage though signs of arterial occlusion were found in 33 patients (22%). These signs were significantly more common after periods of cannulation greater than six hours (43%) than after less than six hours cannulation (17%). During recovery from occlusion all patients had palpable pulsation over the artery even though blood flow seemed to be absent. By the end of follow-up blood flow had returned in 19 of the 33 occluded arteries.

Pulmonary arterial reconstruction for pulmonary coarctation in early infancy.

BACKGROUND: Pulmonary atresia with pulmonary coarctation may complicate diminished and unbalanced pulmonary development. The aim of this study is to assess the outcome of pulmonary arterial reconstruction with cardiopulmonary bypass in early infancy for sufficient and balanced pulmonary development. METHODS: We performed a retrospective review of 15 patients with pulmonary coarctation younger than 4 months of age who underwent pulmonary arterial reconstruction between 2001 and 2005. The mean age and weight were 42.2 days and 3.62 kg, respectively. The patient population included 5 biventricular repair candidates and 10 Fontan candidates. To evaluate the pulmonary arterial development, the preoperative and postoperative pulmonary arterial index and minimum diameter of the pulmonary artery were compared. RESULTS: No early or in-hospital deaths occurred, and there was no nonconfluent pulmonary artery development or segmental mal-development after a mean follow-up period of 14.9 months. Immediate pulmonary flow regulation was required in 2 patients because of excessive pulmonary flow. The mean pulmonary arterial index increased significantly from 103 mm2/m2 to 343 mm2/m2, and the mean minimum diameter of the pulmonary artery increased significantly from 2.02 mm to 4.45 mm. Four biventricular repair candidates completed definitive repair, and 2 required surgical reintervention in the pulmonary artery. Six Fontan candidates completed the Glenn procedure, and 1 completed the Fontan procedure. Three required surgical reintervention in the pulmonary artery. Two late deaths occurred after the Glenn procedure because of ventricular dysfunction and respiratory infection. CONCLUSIONS: Pulmonary arterial reconstruction in early infancy provides sufficient and balanced pulmonary arterial development for pulmonary atresia with pulmonary coarctation.
