Influence of Suprarenal Stentgraft Fixation on Renal Function in Patients After Abdominal Aortic Aneurysm Endovascular Exclusion

Currently, there are two methods of stentgraft implantation considering patients with abdominal aortic aneurysms (AAA) undergoing endovascular repair: the suprarenal and infrarenal fixation. It has been suggested that suprarenal fixation may lead towards impaired kidney function.

The aim of the study was to assess the influence of suprarenal stentgraft fixation on kidney function in patients after endovascular repair of abdominal aortic aneurysms.

Material and methods. The inclusion criteria were fulfilled by 118 patients who were subjected to endovascular treatment, due to abdominal aortic aneurysms. They were consequently divided into two groups - suprarenal (NN) or infrarenal (PN) - based on the stentgraft system used. Both groups were compared on the basis of co-morbidities, operative risk (ASA score), and volume of contrast medium used intraoperatively. The creatinine concentration (cr) and creatinine clearance (Cr.cl) were assessed during the preoperative period, between the 3-rd and 7-th postoperative day, and after 3 months.

Results. Increased creatinine level during the first postoperative week was observed in 12 of 118 patients (10.1%): in the suprarenal group - 7 of 66 (10.6%), and in the infrarenal group 5 of 52 (9.96%). During the 3-rd postoperative month the increase (cr > 1.5 mg/dL) was present in 3 of 118 patients (2.5%): in the suprarenal group - 2 of 66 (3.03%) and in the infrarenal group-1 of 52 (1.9%). The difference between both groups was statistically insignificant. Furthermore, there was no statistically significant difference between creatinine clearance levels considering both groups.

Conclusions. In case of patients undergoing endovascular repair for AAA, implantation of a suprarenal device is a safe method, which does not significantly impair postoperative renal functioning. This increases the number of patients eligible for AAA treatment by means of stentgraft implantations.

1000 Liver Transplantations at the Department of General, Transplant and Liver Surgery, Medical University of Warsaw - Analysis of Indications and Results

The aim of the study was to analyze indications and results of the first one thousand liver transplantations at Chair and Clinic of General, Transplantation and Liver Surgery, Medical University of Warsaw.

Material and methods. Data from 1000 transplantations (944 patients) performed at Chair and Clinic of General, Transplantation and Liver Surgery between 1994 and 2011 were analyzed retrospectively. These included 943 first transplantations and 55 retransplantations and 2 re-retransplantations. Frequency of particular indications for first transplantation and retransplantations was established. Perioperative mortality was defined as death within 30 days after the transplantation. Kaplan-Meier survival analysis was used to estimate 5-year patient and graft survival.

Results. The most common indications for first transplantation included: liver failure caused by hepatitis C infection (27.8%) and hepatitis B infection (18%) and alcoholic liver disease (17.7%). Early (< 6 months) and late (> 6 months) retransplantations were dominated by hepatic artery thrombosis (54.3%) and recurrence of the underlying disease (45%). Perioperative mortality rate was 8.9% for first transplantations and 34.5% for retransplantations. Five-year patient and graft survival rate was 74.3% and 71%, respectively, after first transplantations and 54.7% and 52.9%, respectively, after retransplantations.

Conclusions. Development of liver transplantation program provided more than 1000 transplantations and excellent long-term results. Liver failure caused by hepatitis C and B infections remains the most common cause of liver transplantation and structure of other indications is consistent with European data.
