Introduction & Objective :

Arterial pseudoaneurysms (AP) are relatively rare complications of nephron sparing surgery, with an incidence of 1.7% to 2.6% for laparoscopic partial nephrectomies (LPN). Arterial embolization can play an important role in the management of these cases and avoid radical nephrectomy.

The objective is to evaluate the rate of appearance of AP and other vascular complications after NPL, as well as its treatment.

Methods :

Retrospective analysis of 146 patients treated with PN for renal tumor, of which 114 were performed by laparoscopic approach between January 2012 and October 2017, with a mean post-surgical follow-up time of 43 months (3-70).

Different demographic, morphometric variables (PADUA classification), intra and postoperative complications (Clavien classification), treatment of complications are collected. A descriptive analysis of the series was carried out, as well as the characteristics of the patients who developed AP.

Results :


The majority of patients were men (70%) with a median age of 62 years, with a Charlson index ≥3 and anticoagulation or antiaggregation in 15.4% of the patients respectively. The mean size of the renal tumor was 31.8 mm (15-70), being 39.8, 31.2 and 29% of low, medium and high complexity according to the PADUA classification, respectively.

A postoperative complication rate of 43% was observed, being higher (Clavien III-IV) in 15.8% of the series. Of the 18 patients with major complications, half were of vascular cause, with three cases of AP, with an appearance rate of 2.6%. The mean time of diagnosis of AP was 16.3 days after surgery, after debuting with macroscopic hematuria in two cases, the other case being asymptomatic. The treatment of vascular complications was performed in 55.6% (including AP) by selective arterial embolization.

Conclusions : The rates of complications and the appearance of AP after LPN in our series are similar to those described in the literature. Selective arterial embolization is a safe and minimally invasive treatment option for vascular complications such as AP.
