Three-dimensional CT demonstration of intrahepatic portosystemic venous shunt draining into the inferior vena cava.

In the literature, insufficient attention is paid to the preoperative planning of the approach to adrenal glands using the modern capabilities of computed tomography (CT) navigation. The aim of the work was to demonstrate the possibilities of designing safe access for adrenalectomy using three-dimensional printed models based on preoperative CT data. The possibilities of preoperative access design for edrenalectomy were studied in 362 adrenal tumor patients who underwent CT imaging on Aquillion 64 (Toshiba, Japan), followed by post-processor image processing, construction of multi-plane and 3D reconstructions. All patients were divided into retrospective (n=157) and prospective (n=205) groups. In 3 clinical cases, preoperative access design was supplemented by the creation of a three-dimensional printed model of the adrenal gland with a tumor using the Slicer 4.10.1 software. Reliable anthropometric (body mass index, body shape) and CT-criteria for designing surgical access to the left and right adrenals were determined: diameter of formation; tumor syntopy in relation to the walls of the inferior vena cava; the length of the central adrenal vein and the place where it flows into the inferior vena cava; the location of the tumor relative to the inferior vein of the right lobe of the liver, as well as relative to the gate of the right kidney; location near the aortic-renal vascular triangle, gate of the left kidney and spleen vessels. Three patients with a borderline number of risk criteria for the development of vascular complications associated with the technical difficulties of adrenalectomy (for right adrenals≥4, for left adrenals≥3) underwent CT-segmentation of images with the subsequent creation of three-dimensional plates - a model of an NP tumor with neighboring organs and vessels. Preoperative CT design of the approach, taking into account the risk criteria for complications and the use of 3-D printed models, can reasonably apply endoscopic and open options for adrenalectomy, significantly improving the immediate results of treatment of patients.

SummaryPatients with anomalies of the inferior vena cava (IVC) are rare, are usually asymptomatic and this developmental anomaly is detected during radiologic evaluation of deep vein thrombosis or incidentally during abdominal radiologic evaluation. We report on time resolved three-dimensional magnetic resonance angiography (4D MRA) in a patient with congenital anomaly of the IVC and nonspecific abdominal complaints. 4D MRA is shown for evaluation and detailed diagnosis in vascular venous anatomy. However, due to continuing bloating and irregular bowel movements we investigated carbohydrate malabsorption and a lactose malabsorption was diagnosed. The nonspecific abdominal complaints in this patient with IVC anomaly were due to lactose malabsorption and were treated successfully with a lactose-free diet.@Supplementary material online: www.phlebologieonline.de: http://dx.doi.org/10.12687/phleb2285-1-2016

Abstract This study aimed to evaluate the efficacy of stereotactic body radiotherapy (SBRT) compared with three-dimensional conformal radiotherapy (3DCRT). Forty-three patients with portal vein tumor thrombosis (PVTT)/inferior vena cava tumor thrombosis (IVCTT) treated with SBRT (27 with CyberKnife (CK) and 16 with TrueBeam (TB)) from April 2013 to December 2014, and 54 treated with 3DCRT from June 2008 to March 2013 were evaluated. Dosimetric parameters, response to radiotherapy (RT) and survival outcomes were compared in total SBRT vs. 3DCRT, CK vs. 3DCRT and TB vs. 3DCRT, respectively. The median biologically effective dose 10 (BED10) values in total SBRT, CK, TB and 3DCRT were 73.4 Gy10, 75.0 Gy10, 60.5 Gy10 and 58.5 Gy10, respectively (P < 0.001 in total SBRT vs. 3DCRT, P < 0.001 in CK vs. 3DCRT, P = 0.004 in TB vs. 3DCRT). The tumor response rates were 67%, 70%, 62% and 46%, respectively (P = 0.04, P = 0.04, P = 0.25). The 1-year overall survival rates were 49.3%, 56.7%, 38.1% and 29.3%, respectively (P = 0.02, P = 0.02, P = 0.30), and the 1-year local progression rates were 20.4%, 21.9%, 18.8% and 43.6%, respectively (P = 0.01, P = 0.04, P = 0.10). The use of SBRT made it possible to achieve a higher BED10 compared with the use of 3DCRT. Improvements in local control and survival were achieved in the CK group and the total SBRT group. Our results suggest that SBRT may have the potential to be the standard RT technique for the treatment of PVTT/IVCTT.
