Long-segment thoracoabdominal aortic coarctation in a child with Down syndrome.

Midaortic syndrome is a rare vascular anomaly characterized by coarctation of the descending thoracic and abdominal aorta. Down syndrome is associated with multiple congenital cardiac malformations but is rarely associated with developmental vascular anomalies. Midaortic syndrome may result in severe renovascular hypertension that requires early intervention to prevent life-threatening complications.

Vascular anastomosis for paediatric renal transplantation and new strategy in low-weight children.

The technical aspects of RT in low-weight children should be specific, particularly with regard to VA. This retrospective study assesses the main VA options in paediatric RTs and proposes a new strategy for renal artery trajectory when using the Ao and the right iVC. The sample included 81 patients and was categorized into a group of children weighing <16 kg and the other group of children weighing 16 kg or more.

Urethral duplication--a wide spectrum of anomalies.

Objective: Urethral duplications are rare lower urinary tract anomalies, with multiple anatomical variants described. This paper aims to separate this complex anomaly into different diseases, each with distinct clinical forms according to the disturbance during embryogenesis, yet noting a few similarities that may be helpful in their management. The classification system of urethral duplication is also discussed.

Pelvic fracture urethral distraction defects in children managed by anterior sagittal trans anorectal approach: a facilitating and safe access.

Purpose: Trauma injuries of the posterior urethra resulting from pelvic fracture in children tend to be complete ruptures, with upper dislocation of the prostate. This paper aims to show our experience in using an anterior sagittal transanorectal approach (ASTRA) in the treatment of such injuries.

Materials And Methods: The medical records of 11 patients with pelvic fracture urethral distraction defects who had undergone anastomotic urethroplasty through ASTRA between 1997 and 2009 were reviewed.
