Variations of course and number of renal vessels are not so uncommon and their knowledge is important for planning of minimally invasive renal surgeries. The earlier literature reports a prevalence of precaval right renal artery between 0.8% and 5%. Normally, the right renal artery passes posterior to the inferior vena cava, but it can also be precaval where it passes anterior to inferior vena cava. The multidetector row contrast enhanced computed tomography angiography allows precise evaluation of renal vasculature. The aim of this retrospective study is to determine the prevalence of precaval right renal artery. Amongst 73 MDCT scans studied, we identified 4 cases of precaval right renal artery with the prevalence being 5.48%, more than what is reported in the earlier literature. We also report a single and dominant precaval right renal artery in one of the cases, which is a rare finding. On the basis of these results, we conclude that precaval right renal artery appears to be more common and so the knowledge of this variant holds a major clinical implication in preventing misinterpretation of radiological images and proper planning of interventional procedures and minimally invasive surgeries.

Objective To assess the potential of multidetector-row computed tomography imaging and its reformations in the evaluation of the superior and inferior vena cava normal anatomy and their anatomical variants, and to make a brief review of caval embryogenesis and developmental errors. Methods We retrospectively reviewed a total of 1000 whole-body computed tomography scans performed between January 2010 and December 2016 to assess the normal superior and inferior vena cava anatomy and their variants. Results The normal superior and inferior vena cava anatomy was found in 88.9% of patients, whereas multiple variants were found, ranging from the superior or inferior vena cava duplication, to the azygos continuation of the inferior vena cava. Conclusions Computed tomography is a powerful tool to analyse superior and inferior vena cava anatomical variants. The knowledge and assessment of normal caval anatomy and of its anatomical variants is mandatory in the correct pre-operative planning in surgical and radiological interventions. Knowledge of caval variants is helpful in the differential diagnosis of abdominal or mediastinal masses, to avoid misdiagnosis, as well as in the screening of associated congenital pathologic conditions.

Supernumerary kidney is a rare clinical entity with fused supernumerary kidney being even rarer. Caudally located fused right supernumerary kidney with multiple nephrolithiasis was diagnosed in a 69-years-old lady by Computed Tomography Urography. A separate renal artery arising from the abdominal aorta as well as separate renal vein draining into the inferior vena cava was present along with right sided bifid collecting system. Embryological basis of origin of supernumerary kidney, its diagnosis, clinical significance and management are discussed.

The Right

Retrieval of tip-embedded inferior vena cava filters using endobronchial forceps is a well-described technique. The tip of dorsally tilted filters may be in proximity to the right renal artery, increasing the risk of arterial injury during retrieval. We present one case that illustrates renal artery injury requiring emergent stent graft repair. The three subsequent cases illustrate techniques that avoid renal artery injury using a femoral and jugular approach with the assistance of an arterial fiducial wire. Renal artery injury is a potential complication during retrieval of filters using endobronchial forceps that can be prevented with careful planning.

Routine Chest

A 36-year-old asymptomatic female had a routine chest radiograph to exclude pulmonary tuberculosis, as part of an employee wellness programme. There was opacification of the right lower thorax. Computed tomography and venography demonstrated an incidental right Bochdalek hernia with interruption of the inferior vena cava (IVC) and hepatic venous collateral continuation. The association of a Bochdalek hernia with an anomaly of the IVC is rare, with only one case described in the literature.

<p>Nowadays, there is a tendency in surgery to use more minimally invasive surgical procedures to decrease the risk of intra- and postoperative complications and to reach a faster rehabilitation period. We report a case of successful simultaneous minimally invasive treatment of a patient with kidney tumor. According to ultrasound examination data, the patient had a tumor in the right kidney. A computed tomography scan of the abdomen verified the tumor and detected a thrombus in the inferior vena cava lumen. Embolization of the right renal artery was performed as the first stage in the hybrid operating room. Right-side nephrectomy and thrombectomy from inferior vena cava, as the second stage, were done by using a robotic surgical system. The feature of this case is that embolization and nephrectomy were simultaneously performed during one surgical procedure. On the 10th day, the patient was discharged from the hospital without any signs of deterioration and complications. Thus, the unique work of two surgical teams proficient in mini-invasive technologies allowed to eliminate tumors and tumor thrombi in a single procedure and to reduce the bleeding, in-hospital stay, and rehabilitation period. This method will help more patients with kidney tumors in the future.</p><p>Received 28 June 2018. Revised 3 August 2018.

Primary sarcomas of the great vessels (aorta, pulmonary artery, and inferior vena cava (IVC)) are exceedingly rare. We report a rare case of an undifferentiated intimal sarcoma of the IVC with extension to the right atrium, adrenal, and renal veins. The patient underwent extensive resection, reconstruction of the IVC, and subsequent adjuvant chemotherapy. Patient has tolerated chemotherapy and, at 17 months after resection, the patient remains free of tumor recurrence. Undifferentiated intimal sarcomas remain a rare entity with only five cases of venous undifferentiated intimal sarcomas reported in the literature, two of which occurred in the IVC. Intimal sarcomas tend to carry a poor prognosis with the limited literature available on treatment approaches. Our objective is to highlight this rare entity and possible treatment approach which we utilized. Primary sarcomas of IVC need to be included as part of a complete differential diagnosis in patients with atrial masses or recurrent pulmonary emboli.

Unenhanced Computed Tomography

A 54-year-old male presented to the outpatient surgery clinic with chronic intermittent right inguinal pain. An unenhanced computed tomography (CT) scan during Valsalve maneuver was performed, which demonstrated aortoiliac narrowing. Kinking of the duodenum and renal vasculature, and flattening of the inferior vena cava and iliac vasculature were also noted. A CT angiogram was subsequently performed without Valsalva maneuver which demonstrated complete resolution of the vascular and enteric findings. The case demonstrates that transient aortoiliac narrowing can also occur during voluntary Valsalva maneuver. Awareness of this entity is important so that patients can be reassured about the transient physiologic nature of these findings.
