[Acute renal failure after videolaparoscopic surgery: an avoidable complication?].

Videolaparoscopic surgery exposes the abdominal organs to the mechanical effect of pneumoperitoneum at pressure values between 12 and 15 mm Hg, which are considered safe. Nevertheless, experimental data have shown that this pressure range can represent a hemodynamic risk factor as it may induce a decrease in the venous return to the right ventricle, a decrease in cardiac output, and activation of the sympathetic nervous system and renin angiotensin system. We report two cases of acute renal failure that occurred soon after videolaparoscopy in young female patients without any evidence of ongoing renal disease.

Aneurysm of arteriovenous fistula in uremic patients: is endograft a viable therapeutic approach?

One of the complications of arteriovenous fistulas in chronic hemodialyzed patients is the onset of an aneurysm which can be at risk of rupture. Traditional surgical repair is not always feasible and may not be successful in these cases, leading therefore to the loss of a functioning vascular access and requiring in any case the temporary use of a central venous catheter to allow regular hemodialysis sessions. We applied to this kind of aneurysm the same experience developed in the management of major arterial aneurysms and we considered endografting repair a good alternative in this case.

Relapsing seroma in a uremic patient bearing a PTFE graft as vascular access.

Unlabelled: Seroma is one of the most frequent complications of PTFE vascular grafts and its etiology is still unclear.

Case Report: A 51 year-old male on regular dialytic treatment for seven years underwent the surgical implantation of a vascular prosthesis of homologous safena due to the thrombosis of his native artero-venous fistula. Several years earlier the patient had suffered the amputation of the left forearm because of electric shock.

Continuous ambulatory peritoneal dialysis and sclerosing encapsulating peritonitis: tamoxifen as a new therapeutic agent?

Sclerosing encapsulating peritonitis (SEP) is a serious complication of long-term continuous ambulatory peritoneal dialysis (CAPD), very likely related to a persisting expression of the transforming growth factor beta1 (TGFbeta1) gene on peritoneal mesothelial cells. We report the case of a 67-year-old uremic woman who developed SEP eight years after being placed on CAPD, complicated by eight episodes of bacterial peritonitis. CAPD was therefore stopped and the patient transferred to hemodialysis.

Minimal change nephrotic syndrome with cecum adenocarcinoma.

Membranous glomerulonephritis is the most common glomerular disease associated with malignancy, the association of minimal change glomerulopathy with solid tumor is still uncommon. We report a 72-year-old man with nephrotic syndrome due to minimal change glomerular disease; an accurate seek of underlying malignancy revealed a cecum adenocarcinoma. We had a complete remission of nephrotic syndrome after surgery of carcinoma.
