Influence of respiratory cycle on proximal renal artery motion: an angiographic study in patients undergoing endovascular aneurysm repair.

Background: The purpose of our study was to evaluate the influence of respiratory cycle on proximal renal artery (RA) motion in twenty consecutive patients with abdominal aneurysm and the potential impact on endograft deployment during endovascular aneurysm repair (EVAR).

Methods: Prior to the device introduction, a preoperative angiography to define the location of the RAs was performed by a calibrated pigtail catheter. A measuring tape on the table served as the reference point for all measurements.

Laparoscopic management of benign liver diseases: where are we?

The role of laparoscopic surgery in the management of benign cystic and solid liver tumours appears to differ according to each tumour type. As regards congenital liver cysts, laparoscopic treatment is now the gold standard for treating selected, huge, accessible, highly symptomatic or complicated cysts. In contrast, the laparoscopic approach is not useful for patients suffering from adult polycystic liver disease (PLD), except for type I PLD with large multiple hepatic cysts.
