Abstract
Interventional radiology (IR) is a rapidly expanding medical subspecialty and refers to a range of image‐guided procedural techniques. The image guidance allows real‐time visualization and precision placement of a needle, catheter, wire and device to deep body structures through small incisions. Advantages include reduced risks, faster recovery and shorter hospital stays, lower costs and less patient discomfort. The range of chest interventional procedures keeps on expanding due to improved imaging facilities, better percutaneous assess devices and advancing ablation and embolization techniques. These advances permit procedures to be undertaken safely, simultaneously and effectively, hence escalating the role of IR in the treatment of chest disorders. This review article aims to cover the latest developments in some image‐guided techniques of the chest, including thermal ablation therapy of lung malignancy, targeted therapy of pulmonary embolism, angioplasty and stenting of mediastinal venous/superior vena cava occlusion, pulmonary arteriovenous malformation treatment and bronchial artery embolization for haemoptysis.

Abstract
Background Anti-glomerular basement membrane disease (GBM) disease is a rare autoimmune disease causing rapidly progressive glomerulonephritis and pulmonary haemorrhage. Recently, an association between COVID-19 and anti-glomerular basement membrane (anti-GBM) disease has been proposed. We report on a patient with recurrence of anti-GBM disease after SARS-CoV-2 infection. Case presentation The 31-year-old woman had a past medical history of anti-GBM disease, first diagnosed 11 years ago, and a first relapse 5 years ago. She was admitted with severe dyspnoea, haemoptysis, pulmonary infiltrates and acute on chronic kidney injury. A SARS-CoV-2 PCR was positive with a high cycle threshold. Anti-GBM autoantibodies were undetectable. A kidney biopsy revealed necrotising crescentic glomerulonephritis with linear deposits of IgG, IgM and C3 along the glomerular basement membrane, confirming a recurrence of anti-GBM disease. She was treated with steroids, plasma exchange and two doses of rituximab. Pulmonary disease resolved, but the patient remained dialysis-dependent. We propose that pulmonary involvement of COVID-19 caused exposure of alveolar basement membranes leading to the production of high avidity autoantibodies by long-lived plasma cells, resulting in severe pulmonary renal syndrome. Conclusion Our case supports the assumption of a possible association between COVID-19 and anti-GBM disease.

Abstract
Background Pregnancy is rare in women on hemodialysis. Recommendations for the treatment of secondary hyperparathyroidism (sHPT) and preservation of bone health in pregnant dialysis patients are lacking. Case presentation We present the case of a young woman with end-stage kidney disease (ESKD) due to lupus nephritis, who developed multiple brown tumors while on hemodialysis during her second pregnancy. During her first pregnancy sHPT was well controlled and no skeletal complications occurred. Before the second pregnancy she developed severe sHPT. During pregnancy, dialysis time was increased to 24 h per week, the patient was given oral calcitriol, and the dialysate calcium concentration was set at 1.5 mmol/l. In week 20 the patient complained about bone pain in her left hip. Magnetic resonance imaging revealed a cystic lesion compatible with a brown tumor. The baby was delivered in the 36th week by cesarean section. Further assessment identified multiple brown tumors of her skeleton, including the acetabulum, tibia, ribs, skull, thoracic spine and thumb. She required multiple orthopedic surgeries. Three months after pregnancy, etelcalcetide was started, which brought about a gradual improvement in her sHPT. Conclusions This case demonstrates that the combination of pregnancy and severe sHPT in dialysis patients can have deleterious consequences for bone health.

Abstract
BACKGROUND AND AIMS Transjugular intrahepatic portosystemic shunts (TIPS) are used in patients with cirrhosis for the prevention of variceal rebleeding. METHODS We retrospectively evaluated re-bleeding rate, patency, mortality, and transplant-free survival (TFS) in cirrhotic patients receiving TIPS implantation for variceal bleeding between 1994-2014. RESULTS 286 patients received TIPS (n = 119 bare metal stents, n = 167 polytetrafluorethylene (PTFE)-covered stents) for prevention of variceal re-bleeding. Mean age was 55.1 years, median MELD was 11.8, and the main etiology of cirrhosis was alcoholic liver disease (70%). Median follow-up was 821 days. 67 patients (23%) experienced at least one re-bleeding event. Patients with PTFE-TIPS were at significantly lower risk for variceal re-bleeding than patients with bare metal stents (14% vs. 37%, OR:0.259; p<0.001) and had less need for stent revision (21% vs. 37%; p = 0.024). Patients with PTFE stent grafts showed lower mortality than patients with bare stents after 1 year (19% vs. 31%, p = 0.020) and 2 years (29% vs. 40%; p = 0.041) after TIPS implantation. Occurrence of hepatic encephalopathy after TIPS was similar between groups (20% vs. 24%, p = 0.449). CONCLUSIONS PTFE-TIPS were more effective at preventing variceal re-bleeding than bare metal stents due to better patency. Since this tended to translate in improved survival, only covered stents should be implemented for bleeding prophylaxis when TIPS is indicated.

Abstract
BACKGROUND Early implantation (<72h) of a transjugular intrahepatic portosystemic shunt (TIPS) after acute variceal bleeding (AVB) improves survival in highly selected patients. METHODS We retrospectively assessed bleeding control and survival of unselected cirrhotic patients undergoing early TIPS implantation within 72h. We compared the outcomes to patients meeting early TIPS criteria but receiving late TIPS within 3-28days after AVB and endoscopic/medical treatment. RESULTS Forty-nine patients were included. Mean MELD was 14.4 (±4.4). Thirteen patients (26.5%) presented characteristics that were exclusion criteria in previous early TIPS trials (age>75, CPS>13, HCC>Milan, previous beta-blocker/band-ligation, renal insufficiency). Bare metal and PTFE-covered stents were used in n=32 (65.3%) and n=17 (34.7%) patients, respectively, and showed similar early re-bleeding rates (9.9% vs. 7.1%; p=0.6905) and bleeding-related mortality (25.0% vs. 23.5%; p=0.9906). However, overall re-bleeding rate was lower with PTFE-TIPS (7.7% vs. 64.2%; p=0.0044) over a median follow-up of 18.5 months with a tendency towards improved survival (median 70.5 vs. 13.8 months; p=0.204). Additional 68 patients meeting stringent criteria but receiving late TIPS also showed a favorable bleeding-related mortality (8.8%), which was not achieved in similar n=34 patients by a medical/endoscopic strategy with bleeding-related mortality of 35.7%. CONCLUSIONS An early TIPS strategy using covered stents and implementation of 'stringent criteria' results in a favorable outcome in patients with acute variceal bleeding.

Abstract
Purpose: To determine midterm durability and need for reinterventions after stent-graft placement in atherosclerotic descending thoracic aortic aneurysms. Methods: Fifty-four patients (38 men; mean age 68 years, range 33–87) underwent stent-graft repair of chronic atherosclerotic aneurysms of the descending thoracic aorta between November 1996 and December 2002. Acute aortic syndromes (type B aortic dissections, perforating ulcers, and traumatic dissections) were excluded from analysis. Two types of commercially available stent-grafts were used (Talent and Excluder). Results: The primary technical success rate was 94.4%. In-hospital mortality was 3.7% (2/54). No adverse neurological events were encountered. Of 3 (5.6%) early type I endoleaks, 2 (3.7%) required reintervention; the other type I endoleak closed spontaneously. Mean follow-up was 38 months (range 1–72) in the 52 surviving patients. Four (7.7%) type I, 7 (13.5%) type II, and 4 (7.7%) type III endoleaks were seen. Three 3 patients had additional treatment for endoleaks (proximal stenting [type Ia], open thoracoabdominal repair [type Ib], and embolization [type II]). Two of the 3 reinterventions were performed in the first year of follow-up. One additional patient with a type Ia endoleak not suitable for reintervention is under close observation. There were no differences in the number of endoleaks between the 2 types of stent-grafts. Three-year event-free survival was 63%. Conclusions: Midterm durability of endovascular stent-graft placement in atherosclerotic descending aortic aneurysms seems promising, as the rate of endoleaks requiring reintervention is acceptably low. In our series, endoleak formation occurred during the first year after stent-graft placement, so close follow-up of patients after aortic aneurysm repair is crucial. Further studies are warranted to evaluate long-term durability of this new treatment modality.

Abstract
Objectives To demonstrate the various presentations of acute aortic pathology and to present diagnostic and therapeutic approaches. Methods Diagnostic imaging is the key to the reliable diagnosis of acute aortic pathology with multi-slice computed tomography angiography (CTA) as the fastest and most robust modality. Endovascular aortic repair (EVAR) with stent grafts and open surgical repair are therapeutic approaches for aortic pathology. Results CTA is reliable in diagnosing and grading aortic trauma, measuring aortic diameter in aortic aneurysms and detecting vascular wall pathology in acute aortic syndrome and aortic inflammation. CTA enables planning the optimal therapeutic approach. Stent graft implantation and/or an open surgical approach can address vascular wall pathology and exclude aortic aneurysms. Conclusion Aortic emergencies have to be detected quickly. CTA is the imaging method of choice and helps to decide whether elective, urgent or emergent treatment is necessary with EVAR and open surgical repair as the main treatment approaches. Teaching Points • To present aortic pathology caused by trauma • To present acute aortic syndrome (aortic dissection, intramural haematoma and penetrating ulcers) • To present symptomatic and ruptured aortic aneurysm • To present infection (mycotic aneurysms/aorto-duodenal fistulae) or iatrogenic injury of the aorta • To understand different presentations for treatment planning (EVAR and open surgery)

Abstract
OBJECTIVE The sensitivity of 5-aminolevolinic acid (5-ALA) in detecting intraoperative glioblastoma (GBM) tissue compared to postoperative (18)F-fluoroethyl-L-tyrosine and T1 contrast uptake of tumor cells in positron emission tomography (PET) and magnetic resonance imaging (MRI) scans was investigated in a retrospective image correlative study. METHODS Ten patients with histological verified GBM in eloquent brain regions underwent 11 surgeries with neuronavigation and 5-ALA assisted tumor resection. Residual 5-ALA fluorescence was labeled intraoperatively on the navigation MRI scans and images were fused with postoperative (18)F-FET PET and T1 contrast MRI. RESULTS Intraoperatively, at the end of save resection, in all patients 2-5 faint 5-ALA positive resection planes were detected (mean 3·6), compared to 0-4 (18)F-FET positive resection planes (mean 1·4) and 0-2 positive T1 contrast MRI resection planes in postoperative scans. The difference between the number of 5-ALA and (18)F-FET positive resection planes was statistically significant (P = 0·0002). The histological investigation of 5-ALA positive resection margins demonstrated infiltrative tumor in every case. Residual 5-ALA fluorescence on resection margins and postoperative (18)F-FET uptake areas or residual contrast T1 areas were colocalized in all cases, documented by pre-/postoperative image fusion. CONCLUSION Residual faint 5ALA uptake is documented in large areas at the end of GBM resection and corresponds to tumor infiltration. These 5-ALA positive resection plans exceeded the (18)F-FET uptake areas in postoperative PET scans. Thus, intraoperative 5-ALA residual fluorescence seems to be a more sensitive marker than (18)F-FET PET for residual tumor in malignant gliomas.

Abstract
Transjugular intrahepatic portosystemic shunt (TIPS) creation using bare stents is a second-line treatment for complications of portal hypertension due in part to the relatively high number of reinterventions and the occurrence of new or worsened encephalopathy. Initially, custom-made stent-grafts were used for TIPS revision in cases of biliary fistulae. Subsequently, custom stent-grafts were used for de novo TIPS creation. With the introduction of the VIATORR(®) TIPS endoprosthesis a dedicated stent-graft became available for TIPS creation and revision. The VIATORR(®) demonstrated its efficacy and superiority to uncovered stents in retrospective analyses, case-matched analyses, and randomized studies. The improved patency of stent-grafts has led many to requestion the role of TIPS as a second-line therapy. Currently, randomized trials are warranted to redefine the role of TIPS in the treatment of complications of portal hypertension.

Abstract
BACKGROUND Multidetector CT angiography (CTA) is a non-invasive imaging technique for evaluation of peripheral vascular disease. CTA might be particularly useful for assessment of intermediate- and long-term morphological outcome after endovascular treatment. Validation of CTA vs. the current imaging standard, colour Doppler ultrasonography (CDUS), for quantification of native and in-stent re-stenosis in the superficial femoral artery (SFA) is required. METHODS Seventy randomized patients who underwent stent implantation (n=47) or balloon angioplasty (n=23) underwent 6-month follow-up with CDUS and CTA. CTA was compared with CDUS in both sub-groups of patients in terms of binary re-stenosis (>50% lumen narrowing) and re-occlusion. Agreement between CTA and CDUS was assessed using Kappa (κ) statistics with 95% confidence intervals, and correlation coefficients. RESULTS Binary re-stenosis was detected in 16/70 (22.9%) patients by CTA and 17/70 (24.3%) patients by CDUS (κ=0.88, 95% CI: 0.80-0.96). Re-stenosis rates after balloon angioplasty were 39.1% (9/23) on CTA and CDUS (κ=0.82, 95% CI: 0.66-0.98), and after stent implantation 14.9% (7/47) on CTA and 17.0% (8/47) on CDUS (κ=0.92, 95% CI: 0.84-1.00). Re-occlusions were detected in 3/70 (4.3%) patients by both CTA and CDUS (κ=0.65; 95% CI 0.54-0.76). Significant correlations (r=0.85, p<0.001) were noted between degree of re-stenosis on CTA and peak velocity ratio on CDUS. The correlation coefficient was higher in patients after balloon angioplasty (r=0.94, p<0.001) than in patients after stent implantation (r=0.71, p<0.001). CONCLUSION CTA and CDUS show excellent agreement for evaluation of native and in-stent re-stenosis after endovascular treatment of SFA obstructions. CTA is an appropriate non-invasive imaging modality for follow-up after endovascular therapy.

Abstract
INTRODUCTION The purpose of this retrospective population based study was to investigate the effect of the extent of surgery on overall survival in young versus adult glioblastoma patients in Vorarlberg/Austria during the last 4 years. METHODS Forty-eight patients (median age 62.5 years, ranging from 25-82 years, 19 female and 29 male) with histologically proven glioblastoma received surgery (16 biopsies, 18 partial and 14 complete resections) and postoperative chemo-irradiation with concomitant and adjuvant temozolomide. The median follow up of the patient population was 11.7 months (ranging from 3 to 36 months). Postoperative temporary morbidity was found in 5 out of 48 (10.4%) patients, and no mortality or permanent morbidity occurred. One infection led to revision surgery. FINDINGS Altogether, the 12/24 months overall survival was 54/20.2% with a median survival of 13.7 months. In younger patients (<65 yrs, median 57.5 yrs, 28 patients), the 12/24 months overall survival was 68.4/34.3% with 16.9 months median survival, in the elderly patients (>65 yrs, median 73 yrs, 20 patients) the 12/24 months overall survival was 28.8/5.8%, with 7.7 months median survival (Log-rank, p = 0.0005). Extent of surgery influenced overall survival of the adult group nearly significantly (biopsy versus complete resection: p = 0.06), but did not affect overall survival of the elderly (p = 0.5). CONCLUSIONS Overall survival of elderly glioblastoma patients treated with surgery and chemo-irradiation with concomitant and adjuvant temozolomide is significantly reduced compared to the younger patients. In addition, in the elderly the extent of surgery did not influence the prognosis in our population.

Abstract
BACKGROUND Liver abscess is a rare complication after pancreatectomy. Clostridium perfingens is a rare cause of intrahepatic infections. CASE REPORT A 65-year-old woman with pancreatic cancer underwent explorative laparotomy, during which encasement of the hepatic artery by the tumor was found. Neoadjuvant radiochemotherapy with capecitabine was started, which caused tumor regression, and duodenopancreatectomy was performed. The portal vein was occluded and infiltrated by cancer and therefore was resected and not reconstructed. After a slow recovery, the patient developed hemorrhage at the gastrojejunal anastomosis, which was controlled by fibrin injection. Within a few days, she presented with signs of sepsis, and blood cultures yielded Clostridium perfringens, Streptococcus oralis, Staphylococcus aureus, and Candida albicans. The source of the sepsis proved to be a 9-cm liver abscess, which was drained; cultures grew C. perfringens, Hafnia alvei, and Enterobacter cloacae. Despite antibiotic treatment, the patient died from sepsis and multiorgan failure 27 days after pancreatic surgery. CONCLUSION Such rare infections can follow pancreatic resection with neoadjuvant radiochemotherapy. Clostridium perfringens-associated liver abscess maintains a high mortality rate.

Abstract
PURPOSE To report about the endovascular treatment of isolated iliac artery aneurysms (IIAA) with stentgraft placement and transluminal or CT-guided embolization of the internal iliac artery or the combination of these methods. METHODS AND MATERIALS Over a period of 5.6 years, 36 interventions were performed in 20 patients with 23 IIAAs. In a retrospective analysis patient records were reviewed. The CT-angiography follow-up was evaluated for the presence of re-perfusion of the IIAA and for change of aneurysm diameter. RESULTS Primary success was achieved in 15/23 aneurysms (65%), and secondary success in 21/23 aneurysms (91%). In 5/23 cases two interventions and in 1/23 cases three interventions were necessary to achieve secondary success. Embolization alone, as a therapy for aneurysms involving only the internal iliac artery, had a success rate of 27%. No procedure-related minor or major complications occurred. Mean decrease of aneurysm size during a mean observation period of 14.1 months was 6.9% which was not significant (p=0.3; 95% confidence interval +7-21%). CONCLUSION Endovascular therapy of isolated iliac artery aneurysms performed percutaneously has become a treatment alternative to open surgical repair. This method is feasible and safe with low procedure-related morbidity and mortality. However, on average more than one intervention has to be performed to achieve successful permanent exclusion of the aneurysm and embolization alone in isolated internal iliac artery aneurysms is not sufficient.

Abstract
PURPOSE To investigate whether primary nitinol stenting in the superficial femoral artery (SFA) is beneficial to patients' quality of life (QoL). METHODS One hundred four patients (55 men; mean age 66+/-19 years) with chronic limb ischemia and SFA disease were randomly assigned to primary stent implantation (n=51) or balloon angioplasty (n=53) with optional stenting for a suboptimal angioplasty result (17 of 53). QoL was measured by the SF-36 questionnaire at baseline and at 3, 6, and 12 months post intervention. RESULTS QoL was significantly improved post intervention and up to 12 months in both treatment groups. Significant inverse associations were observed between QoL parameters and restenosis. Comparing primary stenting (n=51) versus balloon angioplasty with optional stenting (n=53) by the intention to treat, no significant differences in QoL were observed. Analyses of stented patients (n=68) versus balloon angioplasty (n=36) patients, however, demonstrated significantly improved measures of QoL after stenting. CONCLUSION Endovascular revascularization of SFA disease improves QoL, and restenosis negatively affects QoL outcomes. After stent implantation, whether primary or secondary, QoL was significantly ameliorated compared to balloon angioplasty alone. However, it remains to be proven in larger cohorts whether primary stenting yields a QoL benefit compared to balloon angioplasty with optional secondary stenting.

Abstract
Background—
Primary stenting with self-expanding nitinol stents of the superficial femoral artery yielded improved morphological and clinical results compared with balloon angioplasty with optional stenting until 12 months in a randomized controlled trial. We now report 2-year data on restenosis and clinical outcomes of these patients.
Methods and Results—
Of 104 patients with chronic limb ischemia and superficial femoral artery obstructions, 98 (94%) could be followed up until 2 years after intervention for occurrence of restenosis (>50%) by duplex ultrasound and for clinical and hemodynamic outcome by treadmill walking distance and ankle brachial index. Restenosis rates at 2 years were 45.7% (21 of 46) versus 69.2% (36 of 52) in favor of primary stenting compared with balloon angioplasty with optional secondary stenting by an intention-to-treat analysis (

=0.031). Consistently, stenting (whether primary or secondary; n=63) was superior to plain balloon angioplasty (n=35) with respect to the occurrence of restenosis (49.2% versus 74.3%;
P
=0.028) by a treatment-received analysis. Clinically, patients in the primary stent group showed a trend toward better treadmill walking capacity (average, 302 versus 196 m;
P
=0.12) and better ankle brachial index values (average, 0.88 versus 0.78;
P
=0.09) at 2 years, respectively. Reintervention rates tended to be lower after primary stenting (17 of 46 [37.0%] versus 28 of 52 [53.8%];
P
=0.14).
Conclusions—
At 2 years, primary stenting with self-expanding nitinol stents for the treatment of superficial femoral artery obstructions yields a sustained morphological benefit and a trend toward clinical benefit compared with balloon angioplasty with optional stenting.

Abstract
BACKGROUND The aim of this study was to determine the technical success after endovascular treatment of acute type B aortic dissections and to evaluate true and false lumen diameter changes at long-term follow-up. METHODS Twenty-eight patients with acute type B-dissection who were treated by stent graft repair presented with rupture (n = 1), contained rupture (n = 2), compromised branch vessels (n = 14), pleural effusion (n = 11), rapid aortic diameter progression (n = 5), persistent pain (n = 3), refractory hypertension (n = 10), and an aortic diameter of more than 4 cm (n = 4). Taking into account the perfusion status of the false lumen, diameter changes were monitored in the thoracic aorta at the level of the stented segment (L1), distal to the stent graft (L2), and at the level of the celiac trunk (L3). RESULTS Severe complications in 9 patients (32%) resulted in 3 deaths for a 30-day mortality rate of 10.7%. Primary sealing of the entry tear was achieved in 86%. At all levels, the true lumen diameter increased significantly after stent graft placement. At the 1-year follow-up, the false lumen in L1 was thrombosed in 90% and the mean difference of diameter reduction was highly significant. In L2, complete false lumen thrombosis occurred in 60% with a significant diameter decrease. In L3, the false lumen thrombosed in only 22%, and the mean difference of false lumen diameter increase reached significance at the 2-year follow-up. CONCLUSIONS Ninety percent of patients were treated successfully with thrombosis of the false lumen in the stented segment. False lumen perfusion distal to the stent graft resulted in diameter increase in several patients leaving these segments an area of concern.

Abstract
We report the case of a 57-year-old man who underwent emergency stent-graft placement in August 2003 due to a contained rupture of a distal descending aortic aneurysm. After 1 month the patient was readmitted with chest pain as well as swallowing disorders. A computed tomographic scan revealed a fistula between the distal esophagus and the excluded aneurysm sac. The patient was treated by an esophagectomy, a cervical esophagostomy, as well as a feeding gastrostomy. The infectious parietal thrombus was partially debrided and the aneurysm sac was filled with vancomycin. After 3 months continuity was reinstalled with a pedicled isoperistaltic transverse colonic conduit. The patient recovered uneventfully. At a 3 month follow-up, he showed no signs of infection. However, he is still being treated with antibiotic therapy of ciprofloxacin for a minimum of 1 year.

Abstract
BACKGROUND Because stent implantation for disease of the superficial femoral artery has been associated with high rates of late clinical failure, percutaneous transluminal angioplasty is preferred for endovascular treatment, and stenting is recommended only in the event of suboptimal technical results. We evaluated whether primary implantation of a self-expanding nitinol (nickel-titanium) stent yielded anatomical and clinical benefits superior to those afforded by percutaneous transluminal angioplasty with optional secondary stenting. METHODS We randomly assigned 104 patients who had severe claudication or chronic limb ischemia due to stenosis or occlusion of the superficial femoral artery to undergo primary stent implantation (51 patients) or angioplasty (53 patients). Restenosis and clinical outcomes were assessed at 6 and 12 months. RESULTS The mean (+/-SD) length of the treated segment was 132+/-71 mm in the stent group and 127+/-55 mm in the angioplasty group. Secondary stenting was performed in 17 of 53 patients (32 percent) in the angioplasty group, in most cases because of a suboptimal result after angioplasty. At 6 months, the rate of restenosis on angiography was 24 percent in the stent group and 43 percent in the angioplasty group (P=0.05); at 12 months the rates on duplex ultrasonography were 37 percent and 63 percent, respectively (P=0.01). Patients in the stent group were able to walk significantly farther on a treadmill at 6 and 12 months than those in the angioplasty group. CONCLUSIONS In the intermediate term, treatment of superficial-femoral-artery disease by primary implantation of a self-expanding nitinol stent yielded results that were superior to those with the currently recommended approach of balloon angioplasty with optional secondary stenting.

Abstract
OBJECTIVE The purpose of the study was to determine technical and clinical results in endovascular repair of thoracic aortic diseases necessitating stent-graft anchoring across the arch vessels. METHODS The causes for endovascular treatment in 58 patients (aged 20 to 84 years) were aneurysms (n = 32), acute type A (n = 2) and type B dissections (n = 17), posttraumatic transections (n = 4), iatrogenic dissection (n = 1), and penetrating ulcers with an intramural hematoma (n = 2). Surgical revascularization of arch vessels was performed in 26 patients before stent-graft implantation. Intentional overstenting of the left subclavian artery resulted in complete occlusion in 8 and was partial in 24 patients. RESULTS The 30-day mortality rate was 3.4%. Overall, 19 major postprocedural complications occurred in 14 (24%) patients. Among patients with left subclavian artery occlusion, 2 patients had major (1 paraplegia, 1 critical arm ischemia), and 3 minor (2 temporary vertebrobasilary symptoms, 1 transient arm claudication) complications. Fourteen (25%) patients had an early endoleak, of whom 5 were treated successfully with a secondary endovascular procedure, 2 necessitated open surgical conversion, and 7 were treated conservatively, with spontaneous sealing of the endoleak in 3. In 53 (91%) in whom computed tomographic follow-up was longer than 3 months (mean, 30.1 months, range, 3 to 85), the aortic diameter along the stented segment decreased in 24, was stable in 19, and increased in 10 patients. CONCLUSION Fixation of the stent graft in the aortic arch can expand the applicability of endovascular repair. Intentional overstenting should be performed with caution to avoid ischemic problems after complete occlusion of left subclavian artery.

Abstract
BACKGROUND Diabetic cardiomyopathy (DCM) is characterized by microvascular pathology and interstitial fibrosis, which leads to progressive heart failure; however, the pathogenesis of DCM remains uncertain. METHODS AND RESULTS Using the streptozotocin-induced diabetic rat model, we evaluated the natural course of DCM over a period of 1 year by serial echocardiography, Western blot analysis for vascular endothelial growth factor (VEGF), endothelial progenitor cell assays, myocardial blood flow measurements, and histopathologic analysis that included terminal dUTP nick end-labeling (TUNEL), capillary and cardiomyocyte density, and fibrosis area. Downregulation of myocardial VEGF expression preceded all other features of DCM and was followed by increased apoptosis of endothelial cells, decreased numbers of circulating endothelial progenitor cells, decreased capillary density, and impaired myocardial perfusion. Apoptosis and necrosis of cardiomyocytes ensued, along with fibrosis and progressive diastolic and then systolic dysfunction. To provide further evidence of the central role of VEGF in the pathophysiology of DCM, we replenished myocardial VEGF expression using naked DNA gene therapy via direct intramyocardial injection of plasmid DNA encoding VEGF (phVEGF165). VEGF-replenished rats showed increased capillary density, decreased endothelial cell and cardiomyocyte apoptosis, and in situ differentiation of bone marrow-derived endothelial progenitor cells into endothelial cells. These anatomic findings were accompanied by significant improvements in cardiac function. CONCLUSIONS These findings suggest that downregulation of VEGF may compromise microvascular homeostasis in the myocardium and thereby play a central role in the pathogenesis of DCM.

Abstract
PURPOSE To determine the primary success and short-term patency of stent application as a primary treatment modality for high-grade lesions of the infrapopliteal arteries compared with treatment with percutaneous transluminal angioplasty (PTA) in critical limb ischemia in a randomized prospective study. METHODS Endovascular therapy was performed on 95 lesions in 51 patients (mean age 72.0 years, range 47-80 years) who presented clinically with Fontaine stages III and IV. One patient underwent treatment in both limbs. After angiographic lesion identification, patients were randomized for treatment by PTA (53 lesions in 27 patients) or stent application (42 lesions in 24 patients). Follow-up by clinical investigation and conventional angiography or spiral CT angiography was performed in 37 patients (57 lesions) 6 to 12 months after the procedure, or when clinically indicated. Evaluation was performed by two observers, double-blinded, with thresholds for lesion restenosis of 50% and 70%. Statistical evaluation was performed on a lesion basis by Kaplan-Meier estimated probability rates, and log-rank and Wilcoxon tests. The primary endpoint was the angiographic patency rate of treated lesions. RESULTS The inter-reader agreement was high (kappa = 0.82). For the stent group the cumulative primary patency at 6 months was 83.7% at the 70% restenosis threshold, and 79.7% at the 50% restenosis threshold. For PTA, the primary patency at 6 months was 61.1% at the 70% restenosis threshold and 45.6% at the 50% restenosis threshold. Both results were statistically significant (p < 0.05). CONCLUSION Infrapopliteal stent application is an effective treatment modality for high-grade lesions in chronic critical limb ischemia. Compared with PTA, higher patency rates can be expected after 6 months.

Abstract
Endovascular stent-graft placement has become a safe and effective treatment modality for various diseases of the distal aortic arch as well as of the descending aorta. However, its effectiveness may be limited by various kinds of endoleaks resulting in persistent or recurrent perfusion of the aneurysm sac. Subsequently, systemic pressurization leads to expansion of the aneurysm sac, exposing the patient to a recurrent risk of aneurysm rupture. We report on the case of a 57-year-old male who underwent emergency stent-graft placement in March 2001 due to a contained rupture of a distal aortic arch aneurysm involving the origin of the left subclavian artery. Due to the emergency condition, a subclavian-to-carotid artery transposition had not been performed prior to stent-graft placement. During follow-up the patient developed a type II endoleak originating from the left subclavian artery with consecutive enlargement of the aneurysm sac. The endoleak was successfully treated by subclavian-to-carotid artery transposition.

Abstract
OBJECTIVE Our aim was to measure the arterial, portal venous, and total perfusion of the liver parenchyma with dynamic, single-section CT in patients with liver cirrhosis before and after transjugular intrahepatic portosystemic shunt (TIPS) placement and to compare the results with normal values. SUBJECTS AND METHODS Perfusion of the liver parenchyma was measured in 24 healthy volunteers and 41 patients with liver cirrhosis using dynamic single-section CT. Seventeen patients underwent TIPS placement, and CT measurements were repeated within 7 days. CT scans were obtained at a single level comprising the liver, spleen, aorta, and portal vein. Scans were obtained over a period of 88 sec (one baseline scan followed by 16 scans every 2 sec and eight scans every 7 sec) beginning with the injection of a contrast agent bolus (40 mL at 10 mL/sec). Parenchymal and vascular contrast enhancement was measured with regions of interest, and time-density curves were obtained. These data were processed with a pharmaco-dynamic fitting program (TopFit), and the arterial and portal venous component and the total perfusion of the hepatic parenchyma were calculated (milliliters of perfusion per minute per 100 mL of tissue). RESULTS Mean normal values for hepatic arterial, portal venous, and total perfusion were 20, 102, and 122 mL/min per 100 mL, respectively. In patients with cirrhosis before TIPS, mean hepatic arterial, portal venous, and total perfusion was 28, 63, and 91 mL/min per 100 mL, respectively, which was statistically significant for all values (p <0.05). After TIPS, hepatic perfusion increased to a mean value of 48, 65, 113 mL/min per 100 mL for arterial (p <0.01), portal venous, and total (p=0.011) perfusion, respectively. CONCLUSION In patients with cirrhosis, the hepatic arterial perfusion increased, whereas portal venous and total perfusion decreased compared with that of healthy volunteers. TIPS placement caused a statistically significant increase of the hepatic arterial and total hepatic perfusion. The portal venous parenchymal perfusion remained unchanged.

Abstract
BACKGROUND To evaluate safety and efficacy of a combined repair of aortic arch aneurysms by sequential transposition of the supra-aortic branches and endovascular stent-graft placement. METHODS Between October 2002 and September 2003, 5 patients (mean age, 79.5 years) presented with aortic arch aneurysms involving the origin of the left carotid artery. Treatment was made by sequential transposition of the left carotid artery into the brachiocephalic trunk and transposition of the left subclavian artery into the already transposed left common carotid artery with consecutive endovascular stent-graft placement into the aortic arch. RESULTS All patients survived both procedures. At completion angiography, a small type 1a endoleak was observed in 1 patient. After 1 week, the patient was readmitted for completion three-dimensional computed tomographic scan. The leak had already occluded spontaneously. Mean follow-up was 10 months (range, 4 to 16 months). At follow-up, all patients had normal computed tomographic scans with regular perfusion of the supra-aortic branches without any signs of endoleaks. CONCLUSIONS Combined repair of aortic arch aneurysms by sequential transposition of the supra-aortic branches with consecutive endovascular stent-graft placement is feasible. Extended application of this technique will enable safe and effective treatment of a highly selected subgroup of patients with aortic aneurysms by avoiding conventional arch aneurysm repair in deep hypothermia and circulatory arrest.

Abstract
Implantation of a transjugular intrahepatic portosystemic shunt (TIPS) for therapy of portal hypertension has been available in Vienna, Austria, since 1991. Ten years of experience with this technique led the Vienna TIPS Study Group to retrospectively analyse characteristics and outcome of all patients undergoing TIPS in Vienna between 1991 and 2001. Survival and subgroup analyses were performed using Mann Whitney U-tests, log-rank tests, Spearman's correlation and Kaplan-Meier analyses. A total of 523 patients underwent TIPS; 23 for acute variceal bleeding, 350 for prevention of variceal bleeding, and 109 for therapy of refractory ascites. Portal hypertension was caused by cirrhosis in 503 patients; 20 presented with other diseases. 253 patients died within the study period, median follow-up was 5.07 years, median survival 4.51 years. The 3-month, 1-year, 3-year, and 5-year survival rates were 83%, 71%, 57%, and 49%, respectively. Etiology of cirrhosis had no effect on survival; patients with TIPS for refractory ascites had poorer survival rates than those undergoing TIPS for prevention of rebleeding. TIPS is a safe and effective therapy for patients with portal hypertension. The first decade of TIPS in Vienna has shown, in line with other publications, that good criteria for patient selection, effective post-interventional management, and close cooperation between internists, interventional radiologists and liver-transplant centers are the key for a good outcome.

Abstract
PURPOSE To evaluate whether stent placement is superior to percutaneous transluminal angioplasty (PTA) in the treatment of chronic symptoms in short femoropopliteal arterial stenoses. MATERIALS AND METHODS One hundred twenty-four limbs in 116 patients, who ranged in age from 39 to 87 years (mean age, 67 years), were randomized to PTA (n = 53) versus PTA followed by implantation of long-medium Palmaz-Stents (n = 71). Inclusion criteria were intermittent claudication or chronic critical limb ischemia, short stenosis or occlusion (lesion length < or = 5 cm), and at least one patent run-off vessel at angiography. The follow-up included clinical assessment, measurement of ankle/brachial index (ABI), color duplex ultrasound, and/or angiography at 6, 12 and 24 months. Angiographic follow-up between 12 and 36 months was available in 54 limbs (45 %). RESULTS Initial technical success was achieved in 50 of 53 limbs (94.4 %) in the PTA group versus 70 of 71 limbs (98.6 %) in the stent group. Overall, major complications occurred in 9.5 % (n = 11), with n = 4 in the PTA group compared to n = 7 in the stent group. No difference was found between the groups of treatment: clinical success at 1 and 2 years was 80.5 and 77.1 % in the PTA group versus 78.1 and 71.0 % in the stent group. The cumulative 1-year and 2-year angiographic primary patency rates were 66.1 and 49.1 % in the stent group versus 76.1 and 66.1 % in the PTA group. The secondary 1-year and 2-year angiographic patency rates were 88.5 and 53.3 % in the stent group versus 82.7 % and 76.2 % in the PTA group. CONCLUSION The primary success rate was slightly higher after stent placement than after PTA. However, the angiographic, clinical and hemodynamic success after 1 and 2 years tends to be slightly better for PTA.

Abstract
PURPOSE To compare the diagnostic accuracy of contrast-enhanced magnetic resonance angiography (MRA) to that of digital subtraction angiography (DSA) in the detection, grading, and measurement of atherosclerotic stenoses involving the aortic arch arteries. METHODS The MRA and DSA studies from 28 patients (16 women; mean age 61.6 years, range 24-83) being evaluated for possible aortic arch vessel disease were examined. The aortic arch vasculature was divided into 9 segments; within each segment, the presence and severity of stenotic or occlusive disease was determined based on a 5-point scale. In addition, stenosis length and distance to the branch were measured in 5-mm increments. Image quality was assessed using a 5-point scale. The accuracy, sensitivity, and specificity values, as well as the positive and negative predictive values in MRA's identification of lesions, were evaluated in comparison to DSA. RESULTS In 28 patients, 189 segments were assessed by both methods. Of these, 173 were correctly rated by MRA, resulting in an accuracy of 91.5%. The accuracy dropped slightly to 86.5% when 11 "not assessable" lesions were included. Sensitivity and specificity for severity measurement were 88.5% and 95.6%, respectively. In 39 of 45 lesions, stenosis length measurements were identical by both methods, but there was a difference of 0.5 cm each in 6 lesions. CONCLUSIONS MRA as compared to DSA shows high accuracy in the detection and grading of lesions involving the aortic arch vessels. The noninvasive nature of this method recommends its use for screening, treatment planning, and follow-up in known or suspected arterial disease in aortic arch arteries.

Abstract
Background—
Drug-eluting stents represent a useful strategy for the prevention of restenosis using various antiproliferative drugs. These strategies share the liability of impairing endothelial recovery, thereby altering the natural biology of the vessel wall and increasing the associated risk of stent thrombosis. Accordingly, we tested the hypothesis that local delivery via gene-eluting stent of naked plasmid DNA encoding for human vascular endothelial growth factor (VEGF)-2 could achieve similar reductions in neointima formation while accelerating, rather than inhibiting, reendothelialization.
Methods and Results—
phVEGF 2-plasmid (100 or 200 μg per stent)–coated BiodivYsio phosphorylcholine polymer stents versus uncoated stents were deployed in a randomized, blinded fashion in iliac arteries of 40 normocholesterolemic and 16 hypercholesterolemic rabbits. Reendothelialization was nearly complete in the VEGF stent group after 10 days and was significantly greater than in control stents (98.7±1% versus 79.0±6%,
P
<0.01). At 3 months, intravascular ultrasound analysis revealed that lumen cross-sectional area (4.2±0.4 versus 2.27±0.3 mm
2
,
P
<0.001) was significantly greater and percent cross-sectional narrowing was significantly lower (23.4±6 versus 51.2±10,
P
<0.001) in VEGF stents compared with control stents implanted in hypercholesterolemic rabbits. Transgene expression was detectable in the vessel wall along with improved functional recovery of stented segments, resulting in a 2.4-fold increase in NO production.
Conclusions—
Acceleration of reendothelialization via VEGF-2 gene–eluting stents provides an alternative treatment strategy for the prevention of restenosis. VEGF-2 gene–eluting stents may be considered as a stand-alone or combination therapy.

Abstract
PURPOSE To report endovascular treatment of a patient with complicated acute aortic type B dissection caused by cannulation of the femoral artery for endoscopic coronary artery bypass (CAB) surgery. CASE REPORT A 63-year-old man underwent single-vessel CAB surgery facilitated by the Da Vinci surgical system. After the procedure, acute lower limb ischemia led to the discovery of a type B dissection from the left subclavian artery to the iliac arteries. The subclavian artery was also dissected, with only minimal flow in the left mammary artery. The visceral and renal vessels originated from the false lumen and were not perfused. Emergent stent-graft placement was undertaken to close the entry tear and re-establish perfusion of the lower extremity as well as visceral and renal organs. Additional stent-grafts were placed in the dissected left subclavian artery to perfuse the left internal mammary bypass and in the inferior mesenteric artery, which arose from the false lumen. Six months after operation, the patient is well. CONCLUSIONS Acute iatrogenic aortic dissection secondary to endoscopic CAB surgery can be treated emergently to restore distal perfusion to vital organs.

Abstract
AbstractActivation of inflammatory and procoagulant mechanisms is thought to contribute significantly to the initiation of restenosis, a common complication after balloon angioplasty of obstructed arteries. During this process, expression of tissue factor (TF) represents one of the major physiologic triggers of coagulation that results in thrombus formation and the generation of additional signals leading to vascular smooth muscle cell (VSMC) proliferation and migration. In this study, we have investigated the mechanisms by which inhibition of coagulation at an early stage through overexpression of tissue factor pathway inhibitor (TFPI), an endogenous inhibitor of TF, might reduce restenosis. In a rabbit femoral artery model, percutaneous delivery of TFPI using a recombinant adenoviral vector resulted in a significant reduction of the intimamedia ratio 21 days after injury. Investigating several markers of inflammation and coagulation, we found reduced neointimal expression of monocyte chemoattractant protein-1 (MCP-1), lesional monocyte infiltration, and expression of vascular TF, matrix metalloproteinase-2 (MMP-2), and MMP-9. Moreover, overexpression of TFPI suppressed the autocrine release of platelet-derived growth factor BB (PDGF-BB), MCP-1, and MMP-2 in response to factors VIIa and Xa from VSMCs in vitro and inhibited monocyte TF activity. These results suggest that TFPI exerts its action in vivo through not only thrombotic, but also nonthrombotic mechanisms.
