A pseudoaneurysm or a false aneurysm is the consequence of a persistent blood leak caused generally by iatrogenic rupture of a vessel wall. In hemodialysis fistula, pseudoaneurysm results from repeated puncturing of the vein at the same site. Surgery and endovascular treatment stay widely used as the treatment of pseudoaneurysm compared to the ultrasound-guided manual compression (UGMC). UGMC is a non-invasive and effective procedure which could be attempted before invasive procedures. We reported two cases of successful treatment of pseudoaneurysm by ultrasound-guided compression. A total thrombosed cavity has been obtained and fistulas could be cannulated in the next session.

Insertion of a peritoneal dialysis (PD) catheter is frequently done by interventional nephrologists, but these procedures are typically only performed for adults. Almost all invasive procedures in children are performed by pediatric surgeons. If a pediatric surgeon is unavailable, the initiation of PD in acute situations may be delayed, thus increasing the risk of complications and chronic kidney disease. For these patients, the main obstacle to initiating renal replacement therapy is access, even when involving central vein catheter (CVC) or peritoneal access. Here we report the case of a 10-kg baby affected by hemolytic and uremic syndrome diarrhea in whom all of the procedures to manage the complications of acute kidney injury (PD catheter insertion, PD catheter revision, CVC placement, and CVC revision) were undertaken by interventional nephrologists. This experience allowed us to rapidly treat the acute kidney injury, recover normal kidney function thereby avoiding chronic complications, and allowing us to discharge the baby from the intensive care unit.

Patients with genetic disorders are potentially more susceptible to present vascular abnormalities compared to the general population. For these patients, unusual difficulties could appear during a CVC placement procedure that could lead to major complications if venous abnormalities are undiagnosed. Ultrasound and fluoroscopy guidance should be used routinely for all patients in order to avoid complications and catheter misplacement.
