Abstract
PURPOSE The aim of this paper is to evaluate the safety and efficacy of endovascular revascularization of malignant superior vena cava syndrome (SVCS) and simultaneous implantation of a totally implantable venous access port (TIVAP) using a dual venous approach. MATERIALS AND METHODS Retrospectively, 31 patients (mean age 67 ± 8 years) with malignant CVO who had undergone revascularization by implantation of a self-expanding stent into the superior vena cava (SVC) (Sinus XL®, OptiMed, Germany; n = 11 [Group1] and Protégé ™ EverFlex, Covidien, Ireland; n = 20 [Group 2]) via a transfemoral access were identified. Simultaneously, percutaneous access via a subclavian vein was used to (a) probe the lesion from above, (b) facilitate a through-and-through maneuver, and (c) implant a TIVAP. Primary endpoints with regard to the SVC syndrome were technical (residual stenosis < 30%) and clinical (relief of symptoms) success; with regard to TIVAP implantation technical success was defined as positioning of the functional catheter within the SVC. Secondary endpoints were complications as well as stent and TIVAP patency. RESULTS Technical and clinical success rate were 100% for revascularization of the SVS and 100% for implantation of the TIVAP. One access site hematoma (minor complication, day 2) and one port-catheter-associated sepsis (major complication, day 18) were identified. Mean catheter days were 313 ± 370 days. Mean imaging follow-up was 184 ± 172 days. Estimated patency rates at 3, 6, and 12 months were 100% in Group 1 and 84, 84, and 56% in Group 2 (p = 0.338). CONCLUSION Stent-based revascularization of malignant SVCS with concomitant implantation of a port device using a dual venous approach appears to be safe and effective.

Abstract
OBJECTIVE/BACKGROUND The aim was to evaluate the feasibility and efficacy of a new method for pre-operative calculation of an appropriate C-arm position for iliac bifurcation visualisation during endovascular aortic repair (EVAR) procedures by using three dimensional computed tomography angiography (CTA) post-processing software. METHODS Post-processing software was used to simulate C-arm angulations in two dimensions (oblique, cranial/caudal) for appropriate visualisation of distal landing zones at the iliac bifurcation during EVAR. Retrospectively, 27 consecutive EVAR patients (25 men, mean ± SD age 73 ± 7 years) were identified; one group of patients (NEW; n = 12 [23 iliac bifurcations]) was compared after implementation of the new method with a group of patients who received a historic method (OLD; n = 15 [23 iliac bifurcations]), treated with EVAR before the method was applied. RESULTS In the OLD group, a median of 2.0 (interquartile range [IQR] 1-3) digital subtraction angiography runs were needed per iliac bifurcation versus 1.0 (IQR 1-1) runs in the NEW group (p = .007). The median dose area products per iliac bifurcation were 11951 mGy*cm2 (IQR 7308-16663 mGy*cm2) for the NEW, and 39394 mGy*cm2 (IQR 19066-53702 mGy*cm2) for the OLD group, respectively (p = .001). The median volume of contrast per iliac bifurcation was 13.0 mL (IQR: 13-13 mL) in the NEW and 26 mL (IQR 13-39 mL) in the OLD group (p = .007). CONCLUSION Pre-operative simulation of the appropriate C-arm angulation in two dimensions using dedicated computed tomography angiography post-processing software is feasible and significantly reduces radiation and contrast medium exposure.

Abstract
INTRODUCTION Over the last decade endovascular stenting of aortic aneurysm (EVAR) has been developed from single centre experiences to a standard procedure. With increasing clinical expertise and medical technology advances treatment of even complex aneurysms are feasible by endovascular methods. One integral part for the success of this minimally invasive procedure is innovative and improved vascular imaging to generate exact measurements and correct placement of stent prosthesis. One of the greatest difficulty in learning and performing this endovascular therapy is the fact that the three-dimensional vascular tree has to be overlaid with the two-dimensional angiographic scene by the vascular surgeon. MATERIAL AND METHODS We report the development of real-time navigation software, which allows a three-dimensional endoluminal view of the vascular system during an EVAR procedure in patients with infrarenal aortic aneurysm. We used the preoperative planning CT angiography for three-dimensional reconstruction of aortic anatomy by volume-rendered segmentation. At the beginning of the intervention the relevant landmarks are matched in real-time with the two-dimensional angiographic scene. During the intervention the software continously registers the position of the guide-wire or the stent. An additional 3D-screen shows the generated endoluminal view during the whole intervention in real-time. RESULTS We examined the combination of hardware and software components including complex image registration and fibre optic sensor technology (fibre-bragg navigation) with integration in stent graft introducer sheaths using patient-specific vascular phantoms in an experimental setting. From a technical point of view the feasibility of fibre-Bragg navigation has been proven in our experimental setting with patient-based vascular models. Three-dimensional preoperative planning including registration and simulation of virtual angioscopy in real time are realised. CONCLUSION The aim of the Nav-CARS-EVAR concept is reduction of contrast medium and radiation dose by a three-dimensional navigation during the EVAR procedure. To implement fibre-Bragg navigation further experimental studies are necessary to verify accuracy before clinical application.

Abstract
PURPOSE The role of myocardial triglyceride (mTG) content in the aging human heart is not entirely understood. The aim of this study was to measure concentrations of mTG content from healthy volunteers and to determine the association between age, mTG content and systolic heart function. Furthermore, the technical stability of the (1)H-magnetic resonance spectroscopy ((1)H-MRS) and the reliability of peak evaluation at 3 T were evaluated. MATERIALS AND METHODS The total study population of 47 healthy volunteers was divided into 4 age classes, according to the age of the subjects (1(st) cohort 20 - 29 years (yrs.), n = 20; 2(nd) cohort 30 - 39 yrs., n = 10; 3(rd) cohort 40 - 49 yrs., n = 9; 4(th) cohort 50 - 60 yrs., n = 8). Cardiac MRI and double triggered (1)H-MRS of the myocardium were consecutively performed using a 3 T scanner. Each participant underwent spectroscopic measurements twice in the same investigation. RESULTS mTG content increases with age. The correlation of age and mTG is minimal (r = 0.48; p < 0.001). The following age-averaged mTG content values expressed as % of mTG signal compared to the water signal were determined for each cohort: 1(st) cohort 0.25 % (± 0.17); 2(nd) cohort 0.48 % (± 0.30); 3(rd) cohort 0.48 % (± 0.18); 4(th) cohort 0.77 % (± 0.70). There was no significant correlation (r = 0.04; p = n.s.) between LV mass and mTG content in healthy volunteers. Within our cohorts, no effects of age or mTG content on systolic heart function were seen (r = - 0.01; p = n.s.). The intraclass correlation coefficient of spectroscopic measurements was high (r = 0.965; p < 0.001). CONCLUSION Myocardial TG content increases with age. The normal age-dependent concentration ranges of myocardial lipid metabolites reported in this study may be helpful for the correction of acquired (1)H-MRS data in patients when evaluating metabolic and cardiovascular diseases in future magnetic resonance spectroscopy studies.

Abstract
Complex lesions within the femoro-popliteal vascular territory, amongst others, include more than 15 cm long or heavily calcified occlusions of the superficial femoral artery (SFA) or total occlusions of the popliteal artery (PA). For those type-C/-D lesions TASC-II recommendations originating from 2007 advocate bypass surgery as the therapy of choice if the patient is a suitable candidate for this. Against the background of evolving endovascular techniques which often allow recanalization of even long and calcified lesions as well as improved patency rates after endovascular treatment of such complex lesions, many vascular specialists go for an endovascular-first approach for the treatment of challenging lesions, last but not least in those patients unfit for surgery or in those lacking an adequate conduit or distal target vessel segment. This review focuses on two important aspects of treating complex femoro-popliteal lesions by an endovascular approach. The first part covers techniques to pass a complex lesion with a guidewire, while the second discusses strategies to improve the outcome of the endovascular reconstruction in terms of patency and clinical success.

Abstract
PURPOSE To evaluate the feasibility, frequency of use, types of intervention and labor costs of a formal round-the-clock interventional radiology on-call service. MATERIALS AND METHODS In 11/2011 a formal and permanent out-of-hour interventional radiology rota in addition to the general radiology out-of-hour rota (OOHR) was established. We retrospectively screened the interventional radiology database for procedures completed outside regular working hours, reviewed all interventions and manually selected cases in which the on-call interventionist was called in from home. We determined the type, frequency of use and costs (€/year and procedure) of this service between 1/2012 and 12/2012. The referring physicians' (sub-) specialties were evaluated. RESULTS During the 12-month period, the on-call interventionists (n = 3) performed 92 procedures OOH. The procedures included angiography and hemorrhage control (n = 36, 39.1 %), angiography and intervention for acute limb ischemia (n = 25, 27.2 %), percutaneous biliary drainage (PTCD) (n = 10, 10.9 %), angiography for non-occlusive ischemia (n = 7, 7.6 %), and other (n = 14, 15.3 %). The total labor costs for the OOHR were € 42,312.21 (€ 32,982.60 lump sum for stand-by, € 9,329.61 for hours spent on procedures). The labor costs per procedure totaled € 459.92. The referring physicians' specialties were general/visceral (n = 25), vascular surgery (n = 24), internal medicine (n = 21), cardiac/thoracic vascular (n = 9), trauma surgery (n = 5), urology (n = 5), and anesthesiology (n = 3). CONCLUSION A formal interventional OOHR is practicable in a university hospital setting. Most procedures were requested by general, vascular, and thoracic surgery as well as internal medicine with a focus on hemorrhage control, treatment of acute limb ischemia, and PTCD. The overall labor costs for the OOHR appear moderate. KEY POINTS • In a university setting an OOHR for IR is feasible.• Labor costs per procedure appear moderate.• Hemorrhage control and treatment of limb ischemia were the most frequent procedures.

Abstract
OBJECTIVES To evaluate the technical success, clinical outcome and safety of percutaneously placed totally implantable venous power ports (TIVPPs) approved for high-pressure injections, and to analyse their value for arterial phase CT scans. METHODS Retrospectively, we identified 204 patients who underwent TIVPP implantation in the forearm (n=152) or chest (n=52) between November 2009 and May 2011. Implantation via an upper arm (forearm port, FP) or subclavian vein (chest port, CP) was performed under sonographic and fluoroscopic guidance. Complications were evaluated following the standards of the Society of Interventional Radiology. Power injections via TIVPPs were analysed, focusing on adequate functioning and catheter's tip location after injection. Feasibility of automatic bolus triggering, peak injection pressure and arterial phase aortic enhancement were evaluated and compared with 50 patients who had had power injections via classic peripheral cannulas. RESULTS Technical success was 100%. Procedure-related complications were not observed. Catheter-related thrombosis was diagnosed in 15 of 152 FPs (9.9%, 0.02/100 catheter days) and in 1 of 52 CPs (1.9%, 0.002/100 catheter days) (p<0.05). Infectious complications were diagnosed in 9 of 152 FPs (5.9%, 0.014/100 catheter days) and in 2 of 52 CPs (3.8%, 0.003/100 catheter days) (p>0.05). Arterial bolus triggering succeeded in all attempts; the mean injection pressure was 213.8 psi. Aortic enhancement did not significantly differ between injections via cannulas and TIVPPs (p>0.05). CONCLUSIONS TIVPPs can be implanted with high technical success rates, and are associated with low rates of complications if implanted with sonographic and fluoroscopic guidance. Power injections via TIVPPs are safe and result in satisfying arterial contrast. Conventional ports should be replaced by TIVPPs.

Abstract
This article focuses on radiological imaging of complications after interventional percutaneous insertion of totally implantable venous access ports (TIVAPs) which were placed in the forearm. Thus far most reviews have dealt with pectorally-placed TIVAPs. Compared with the pectoral approach, implantation in the forearm has been associated with certain complications owing to a longer route of the port catheter within a smaller vein, and owing to the route across the elbow joint, resulting in higher rates of catheter-associated thrombosis and possible mechanical complications. The purpose of this review is to describe the complications after implantation of TIVAPs in the forearm, and to make radiologists familiar with the key findings of the complications during radiological imaging, including colour-coded and compression Duplex ultrasound, computed tomography, and digital subtraction venography.

Abstract
OBJECTIVES Cigarette smoking-induced airway disease commonly results in an overall increase of non-specific lung markings on chest radiography. This has been described as "dirty chest". As the morphological substrate of this condition is similar to the anthracosilicosis of coal workers, we hypothesised that it is possible to quantify the radiological changes using the International Labour Organization (ILO) classification of pneumoconiosis. The aims of this study were to evaluate whether there is a correlation between the extent of cigarette smoking and increased lung markings on chest radiography and to correlate the chest radiographic scores with findings on CT studies. METHODS In a prospective analysis a cohort of 85 smokers was examined. The cigarette consumption was evaluated in pack years (defined as 20 cigarettes per day over 1 year). Film reading was performed by two board-certified radiologists. Chest radiographs were evaluated for the presence of thickening of bronchial walls, the presence of linear or nodular opacities, and emphysema. To correlate the smoking habits with the increase of overall lung markings in chest radiography, the ILO profusion score was converted to numbers ranging from zero to nine. Chest radiographs were rated according to the complete set of standard films of the revised ILO classification. RESULTS 63/85 (74%) of the smokers showed an increase in overall lung markings on chest radiography; 32 (37%) had an ILO profusion score of <1/1, 29 (34%) had an ILO profusion score of <2/2 and 2 (2%) had an ILO score of ≥ 2/2. There was a significant positive linear correlation between the increase of overall lung markings on chest radiography and the cigarette consumption quantified as pack years (r=0.68). The majority of the heavy smokers (>40 pack years) showed emphysema; there was no significant difference between the prevalence of emphysema as diagnosed by CT (62%) or chest radiography (71%) (p<0.05).The most common findings in CT were thickening of bronchial walls (64%) and the presence of emphysema (62%) and of intralobular opacities (61%). Ground-glass opacities were seen in only 7% of our patients. CONCLUSION Bronchial wall thickening and intralobular opacities as seen in CT showed a positive linear correlation with the increase of overall lung markings on chest radiography.

Abstract
INTRODUCTION To evaluate the frequency of enlarged hilar or mediastinal lymph nodes in patients suffering from chronic obstructive pulmonary disease (COPD). METHODS In a retrospective study, 89 patients with proven COPD were analysed. Exclusion criteria were history of malignant disease or clinical evidence of pneumonia. Prevalence, size, and localisation of enlarged lymph nodes were assessed by multi-slice computed tomography (MSCT) and correlated with the clinical stages following the GOLD classification as well as the MSCT findings of bronchitis and emphysema. RESULTS 44/89 (49%) of our patients showed enlarged lymph nodes. Lymph node enlargement was more often seen in the mediastinum (48%) than the hilar region (20%). The most common localisation of enlarged mediastinal lymph nodes was the regional station 7 following the ATS mapping (infracarinal). Patients with a stage I following the GOLD classification showed enlarged lymph nodes in 49% (18/37), stage II in 46% (12/26), stage III in 58% (7/12) and stage IV in 50% (7/14). These findings did not differ significantly (P > 0.05). Severe airway wall thickening (42/89) was significantly more often associated with an increase of nodal enlargement (64%) (P < 0.05). CONCLUSION The present study demonstrates that enlarged hilar and mediastinal lymph nodes may occur in a rather high percentage of patients suffering from COPD, especially in those with the MSCT finding of severe bronchitis.

Abstract
Mycoplasma ovipneumoniae and Mycoplasma arginini were the species of Mollicutes most commonly isolated from 175 goats with respiratory disease in Ontario. The pathogenicity of M. ovipneumoniae, strain B321B and M. arginini, strain D53e, was assessed in goats following endobronchial inoculation. One out of three two year old goats developed fever after inoculation with a pure culture of strain B321B, and it had extensive subacute fibrinous pleuritis when necropsied three weeks later. Neither of the remaining goats had lesions in the respiratory tract. Mycoplasma ovipneumoniae was recovered from one of the animals four days after inoculation, but not at necropsy from any of the goats, at which time a marked humoral immune response with growth inhibiting antibodies was detected. In a second experiment three four to five week old goats were inoculated with the same strain and three other goats were given placebo treatment. One experimental goat developed fever and coughing, and it had extensive subacute fibrinous pleuritis in the right side and pneumonia. Another goat had focal pneumonia in the left diaphragmatic lobe. Microscopically there was subacute hyperplastic suppurative bronchiolitis, atelectasis and nonsuppurative alveolitis. The infected animals did not clear the mycoplasma and not all of them produced antibodies. Mycoplasma arginini, strain D53e, did not induce lesions in any of four goat kids within 14 days after inoculation but did cause transient elevations in rectal temperature, circulating monocytes, circulating neutrophils and blood fibrinogen. Mycoplasma arginini was infective and immunogenic for all inoculated animals and showed a particular affinity for the tonsil. Thus, this study provides the first evidence that M. ovipneumoniae is pathogenic for goats causing pneumonia and pleuritis.(ABSTRACT TRUNCATED AT 250 WORDS)
