Objective: This study aimed to review the experience at a large regional tertiary centre of open radical nephrectomy (RN) with vena caval thrombectomy with cardiopulmonary bypass (CPB) and hypothermic circulatory arrest (HCA) for the management of renal masses. Method: Data on patients with renal masses who had undergone RN and vena caval thrombectomy with CPB and HCA had been prospectively collected at two centres over a 19-year period (2000–2019). Twenty-three consecutive patients were identified and retrospectively analysed for operative and tumour characteristics and for postoperative outcome. Kaplan–Meier survival analysis was performed to compare patient outcomes based on tumour characteristics. Results: Median operating time was 358 minutes (interquartile range (IQR)=94 minutes), median bypass time was 117 minutes (IQR=28.5 minutes) and median circulation arrest time was 25 minutes (IQR=18.5 minutes). The median hospital length of stay was 11 days (IQR=5.3 days). Total complication rate was 52% ( n=12), consisting of four minor and eight major complications (Clavien–Dindo score >IIIa), including one intraoperative death. The overall five-year survival rate was 73% (11/15), with a median follow-up time of 53.1 months. Eleven (48%) patients were surgically cured, with a median follow-up time of 60.1 months (IQR=71.8 months). Disease recurrence was seen in eight (35%) patients, of whom four died. Patients who died survived for a median of 46.5 months. Median survival after the diagnosis of metastatic disease was seven months. Conclusions: We report the largest Australian cohort of RN with vena caval thrombectomy with CPB and HCA. We demonstrate outcomes comparable to major overseas centres, with an overall five-year survival rate of 73%. This suggests that even patients with extensive venal caval thrombus from renal masses can experience long-term survival benefit from RN and venal caval thrombectomy. Level of evidence: Level 3.

Renal angiomyolipomas are uncommon benign tumors containing fatty tissue. Only a few cases of infiltrating angiomyolipomas have been reported. We aimed to describe a case of a 65-year-old woman presenting a peripheral angiomyolipoma of the left kidney with CT evidence of involvement of the renal vein. The lesion has been found incidentally during abdominal CT for an unrelated reason. The patient underwent surgical treatment considering the vascular extension of the lesion and the risk of thromboembolic complications. The pathological analysis confirmed the diagnosis of renal AML in the upper pole of the left kidney invading the renal vein without malignancy.No post-operative complications and the evolution was favorable.

Angiomyolipomas are benign tumors that can occur in the kidneys. Though venous invasion is a common complication of renal cell carcinoma, it rarely occurs with angiomyolipoma given its benign nature. We aim by this article to conduct an extensive literature review documenting rare cases of angiomyolipomas with venous extension, particularly with inferior vena cava invasion. The literature review was conducted following PRISMA checklist, using PubMed searching for English and non-English articles up to January 2020, and Mesh terms: angiomyolipoma, inferior vena cava, vein. Only cases reporting patients with angiomyolipomas with venous extension were included. Data extraction of different patients' parameters was conducted by two independent researchers in a uniform manner to a detailed datasheet. The search ended up with 90 cases, after excluding 116 cases for multiple reasons. Venous invasion of angiomyolipoma is a rare phenomenon. Clinical presentation is similar to any other renal tumor. Imaging is primordial for diagnosis and classification. Surgery is indicated as soon as venous involvement is demonstrated. In most cases, the prognosis is favorable with low morbidity and mortality.
