A case of traumatic ulnar artery aneurysm is presented in this study, and the relationship between the various forms of ulnar artery aneurysm and the different methods of treatment, as well as the arterial implications are discussed. The individual palmar arch anatomy may indicate and influence the choice of management technique, in each case.

During a 6-year period, 24 patients, aged 7 days to 18 years, underwent palliative surgery for single-ventricle heart malformations; 22 has single-left ventricle with outlet chamber (14 with L-transposition); only two had type C malformation (van Praagh). They were subdivided according to physiology into two groups: the first included 15 patients with decreased pulmonary blood flow, whose main clinical feature was arterial desaturation; the second consisted of nine patients with increased pulmonary blood flow, who presented early with unmanageable heart failure. The first group was treated with a Blalock-Taussig shunt (typical or modified) in 12 cases (one death due to preoperative acute renal failure), with a Waterston or Potts shunt in two cases (both died early postoperatively), and by enlargement of the bulbo-ventricular foramen in one (who died at operation). ⋯ Patients of the second group received a pulmonary artery banding plus a number of associated procedures: coarctation repair (2), ligation of a patent ductus arteriosus (2), Blalock-Hanlon atrial septectomy (1), tricuspid valve replacement (1). There was only one early death due to critical subaortic stenosis produced by a restrictive outlet foramen; however, there were five late deaths and two cases of surgical failure with persistent pulmonary hypertension. An analysis of the best palliative approach in patients with single-ventricle heart malformations is made, based upon the results of this series and taking into consideration the possibility of future intracardiac repair.
