... to have persistent retroperitoneal lymphadenopathy, with normal tumour markers. The patient was planned for a retroperitoneal lymph node dissection with right pelvic node dissection ( Fig. 1). It was noticed on computed tomography scan that patient had a precaval right renal artery and due precaution was given to this anomaly during the surgery (Fig. 2). The peri-operative course was uneventful. On final histopathology, 26 of 39 lymph nodes showed post-chemotherapy fibrosis, while one node showed cartilage formation suggestive of mature ...

OBJECTIVES
The 18 mm and 16 mm conduits in extracardiac total cavopulmonary connection (eTCPC) were reported to be optimal based on energy loss and flow stagnation at the relatively early phase. However, because the artificial conduit lacks growth potential, we have recently encountered some cases in which the conduit needs to be changed several ye...
Vascular navigation is a prerequisite to transcatheter cardiac interventions. The current standard approach to catheter navigation relies on real-time fluoroscopy, while this technique utilizes ionizing radiation and it places the interventionalist at risk for eye cataracts and cancer. The shielding equipment needed to mitigate these risks is assoc...
Purpose
To validate the safety and effectiveness of transarterial chemoembolization (TACE) combination with lenvatinib and sintilimab in treating hepatocellular carcinoma (HCC) patients with inferior vena cava (IVC) and/or right atrium (RA) tumor thrombosis (TT).
Methods
This study retrospectively analyzed HCC patients with IVC and/or RA TT treate...

... The final position of the kidney during migration from the pelvis to lumbar region defines the position and number of renal arteries. [1][2][3][4] There is good correlation between variants in renal vasculature and ectopic kidney. The incidence rate of renal anomalies in this group is about 20%-30%. ...
... 4,6 A solitary dominant precaval right renal artery(RRA) is a rare occurrence, with about 10 cases described in the literature. 2,7 The origin of a precaval RRA may be from a persistent caudal vessel originating anteriorly from the aorta after formation of the inferior vena cava, but before the descent of the gonad [8] In addition to a precaval RRA being more easily iatrogenically injured (i.e., during endopyelotomy) or more easily mistaken with other vessels such as the mesenteric or gonadal artery, it can be one of the causes for UPJ obstruction. Therefore, awareness of their existence, ideally preoperatively, is critical to prevent significant morbidity (e.g., nephrectomy) 1 Accurate preoperative knowledge of renal vascular anatomy is obligatory for surgical planning. ...
Knowledge of aberrant renal vasculature is critical for preoperative planning of either open or minimally invasive renal surgery. A precaval right renal artery is a rare anatomical variant in which the artery passes anterior to the inferior vena cava(IVC), as opposed to coursing posteriorly. When encountered, this artery is mostly accessory and thus accompanied by renal vessels in orthotopic position. Here, we describe an unusual instance of a solitary, main precaval right renal artery. It can be diagnosed preoperatively by a cross‐sectional imaging study. Awareness of this anomaly is very important to prevent iatrogenic injury during surgical intervention.
