Reducción hidrostática como método terapéutico de la invaginación intestinal en el niño: experiencia en 43 pacientes / Hydrostatic reduction as a therapeutic method of intestinal intussusception in children: experience in 43 patients

Hydrostatic reduction was attempted in 43 children with intestinal intussusception: 20 male, aged 2 to 48 months, that consulted at the Clinical Hospital of the Catholic University in Santiago. Hydrostatic reduction was successful in 33 children (77 percent) that were discharged from the hospital 24 to 96 hours after the procedure. A partial reduction was achieved in 10 patients (23 percent) who required surgery and were discharged from the hospital 5 to 8 days after the procedure. Our results are similar to those reported abroad and allow the recommendation of hydrostatic reduction as the treatment of choice for intestinal intussusception

Anglioplastía transluminal percutánea (ATP) y endoprótesis en el tratamiento de estenosis venosas centrales y periféricas, de fístulas arteriovenosas para hemodiálisis crónica / Percutaneous transluminal angioplasty and endoprosthesis in the treatment of the central and peripheral venous stenoses of arteriovenous fistula for chronic hemodialysis

We studied retrospectively 48 patients with arteriovenous fistulae stenoses, that were followed during 24 months. When the fistulography disclosed an stenosis, a percutaneous thrombolysis was done. These procedures were repeated as needed. Twenty four patients had a peripheral vein stenoses, 20 had subclavian vein stenosis and 4 had both veins compromissed. All were dilated with percutaneous transluminal angioplasty. Five stents were installed in the subclavian vein and five in peripheral veins. Two patients required thrombolysis. The procedure was succeful in 96 percent of peripheral lesions and 92 percent of central lesions. There was regression of superior limb edema in 16 of 20 patients. Five patients had an subclavian treated veins remained patent. The use of percutaneous transluminal angioplasty and intravascular stents, maintains long term arteriovenous fistulae permeability and has similar results to surgical procedures

Rol diagnóstico de la combinación tomografía computada - angiografía en lesiones traumáticas de la aorta torácica / Diagnostic role of the combination of computed tomography and angiography in traumatic injury of thoracic aorta

Aim: To assess tha diagnostic value of the combination of computed tomography and angiography in aptients with blunt thoracic trauma and suspicion of aortic injury. Patients and methods: restrospective analysis of six patients, aged 22 to 72 years old, with traumatic thoracic aorta injury secondary to severe trauma, specially car accidents, seen between 1985 and 1994. Results: an early diagnosis was done in 3 patients. One patient, in whom diagnosis was delayed, died before surgery. In 3 cases, CAT scan showed indirect evidence of aortic rupture, consisting in alterations of aortic outline. In other 3 patients, it showed hemomediastinum, associated to a left hemothorax in one case. Angiography confirmed the diagnosis, localized and characterized yhe injury in all patients. Conclusions: the delay in the diagnosis of aortic injury may be fatal. The combination of CAT scan and angiography has a high sensitivity and specificity to localize and characterize lesions of the aorta or its branches or associated organs, essential step for surgical planning. CAT scan restrict the use of angiography, avoiding false negative studies, but cannot be used as the sole diagnostic procedure
