Abstract
PURPOSE The aim of this study was to assess the effectiveness of endovascular treatment of isolated iliac artery aneurysms (IAAs). MATERIALS AND METHODS Between March 1999 and March 2004, 15 isolated IAAs in 13 patients (mean age: 71.8 years) were selected for endovascular repair by means of a covered stent or stent-graft: 12 were in the common iliac artery (2 with the proximal end 12 mm from the aortic bifurcation and 2 involving the distal hypogastric artery), and three were in the external iliac artery. The preoperative study and the follow-up (at 3, 6 and 12 months and yearly thereafter) were performed by computed tomography (CT) angiography. RESULTS Primary technical success was obtained in all cases, without periprocedural complications. Two patients died within 3 months and were not considered for follow-up. Follow-up (mean duration: 25 months, range: 6-60 months) in the remaining 11 patients, affected by 13 aneurysms, showed aneurysm exclusion in nine cases and progressive shrinkage of the aneurysmal sac in four cases, whereas in the other five, the size of the aneurysm remained unchanged. In a patient with bilateral IAA, bilateral proximal endoleaks were observed after 2 years, and the patient was treated with a bifurcated aortic stent-graft. In another patient with a large aneurysm, a left aortofemoral bypass became necessary after 2 months because of stent-graft dislodgement. In another patient, an endoleak from the hypogastric artery occurred after 2 years but was not treated. CONCLUSIONS Endovascular treatment of isolated IAA is a feasible procedure that is less invasive than surgery and yields excellent short-and midterm results. However, a longer follow-up and larger patient series are needed to verify the long-term efficacy of this form of treatment.

Abstract
OBJECTIVES The continued advances in imaging and stent/stent-graft technology have considerably expanded the indications for endovascular approach also in vascular trauma. We report our institutional experience with endovascular treatment of peripheral arterial injuries after blunt trauma. METHODS Between January 2000 and June 2006 out of a series of 81 patients, 10 male patients (mean age of 50+/-14 years) with peripheral arterial injuries were managed endovascularly. At admission, haemorrhagic shock was present in three patients. Artery location involved common femoral (n=2), subclavian (n=2), axillary (n=2), external iliac (n=2), superficial femoral (n=1), and popliteal (n=1). Type of lesion was as follows: pseudoaneurysm (n=4), dissection (n=4), expanding haematoma (n=1), and arterio-venous fistula (n=1). Follow-up program included visit and duplex-ultrasonography, X-rays and/or spiral-computed tomography at 6-month interval during the first year, and yearly thereafter. RESULTS The lesion was excluded in all cases. All patients survived. Major complications did not occur. Mean hospitalisation was 13 days. Limb-salvage was 100%. Follow-up ranged from 3 to 60 months (mean 16); a late occlusion of a popliteal stent-graft was managed with another endovascular procedure. CONCLUSION In our experience, endovascular treatment of vascular injuries after blunt trauma was feasible and effective.

Abstract
Background Echinococcosis rates vary in different parts of the world. Italy is regarded as a middle to high risk country with over 1,000 cases requiring surgery each year. Liver (45–75%) and lung (10–50%) are the most frequent locations of this parasitosis. Case presentation The authors report a clinical case of a 62 year old woman, admitted to hospital with left flank pain. Plain radiographs of the abdomen, ultrasound, CT and MRI scans were performed and the presence of a 3-cm lesion of the left adrenal gland was demonstrated. A diagnosis of hydatid cyst was made. The patient underwent transabdominal laparoscopic left adrenalectomy. Histopathological examination confirmed the presence of a hydatid cyst in the left adrenal gland. Conclusion A hydatid cyst was correctly diagnosed on the basis of radiologic findings. The uncomplicated cyst was successfully resected using a laparoscopic approach. The pathological features of this case are presented in this paper.

Abstract
BACKGROUND AND AIM Enteric fistulas are defined by their sites of origin, communication and flow. We evaluate the treatment of complex patients with entero-cutaneous fistulae with large abdominal wall defects. MATERIALS AND METHODS Retrospective case note review of 19 patients (15 males, median age 46 years) treated at the Department of Surgical Sciences, University of Insubria, Varese, Italy. These were distinguished by multiple/wide gastrointestinal fistula orifices, with total discontinuity of bowel. Fistulas were not covered by abdominal wall thus presenting with a giant abdominal wall defects. Surgery was planned once adequate nutritional status was present. RESULTS All fistulas resulted from previous surgery for IBD in 7 cases (37%), abdominal trauma 4 (21%), acute necrotic infected pancreatitis 3 (16%), intra-abdominal malignancy 3 (16%), and diverticular disease 2 (10%). The most common site of presentation was ileum (80%). Median fistula output was 800ml/day (range 400-1600ml/day). Seltzer's prognostic index identified malnutrition in 70% of patients at the time of presentation. The elapsed mean time from onset of fistula and elective time of surgical management were 184 days (range 20-2190 days). The VAC system was used in the last 7 patients preoperatively and in 6 patients with postoperative abdominal wound dehiscences that could not be closed immediately and who were at high risk for healing complications. There were no complications from the VAC therapy. Surgery was successful in 69% of cases. Mortality rate was 21%. Factors related to mortality were persistent malignancy, malnutrition and sepsis. CONCLUSIONS After optimization of nutritional status surgery with en bloc resection of fistula offers best results. In this series, cancer and sepsis were unfavourable factors for outcome. These fistulas may be successfully managed with a multidisciplinary approach.

Abstract
Rectal cancer is one of the most common tumors worldwide; it accounts for approximately 25-30% of cancers arising in the large bowel. Owing to greater distribution of screening programs and better attention from both patients and General Practitioners to this disease, in recent years we have observed an increasing number of cases diagnosed in the early stages, with a consequent better prognosis. The improved 5-year survival is also partially due to better, and more accurate, diagnostic techniques and to more curative treatments. In this review, the authors analyze and discuss the more recent diagnostic techniques for an accurate preoperative staging of rectal cancer, highlighting each method's advantages and limits for their routine use in clinical practice.

Abstract
The purpose of this paper is to present a case of emergency endovascular treatment of a symptomatic gastric artery aneurysm (GAA) with stent graft. A symptomatic aneurysm of a "gastro-hepatic" trunk in a 63-year-old patient was excluded with stent graft. Treatment was successful and without complications. Follow-up computed tomography-angiography confirmed the exclusion of the aneurysm after 6 months. Endovascular therapy with stent graft can be considered a feasible and effective approach for the treatment of GAAs in patients with suitable anatomy.

Abstract
The objective of this study was to analyze three ureteral stenting techniques in patients with malignant ureteral obstructions, considering the indications, techniques, procedural costs, and complications. In the period between June 2003 and June 2006, 45 patients with bilateral malignant ureteral obstructions were evaluated (24 males, 21 females; average age, 68.3; range, 42-87). All of the patients were treated with ureteral stenting: 30 (mild strictures) with direct stenting (insertion of the stent without predilation), 30 (moderate/severe strictures) with primary stenting (insertion of the stent after predilation in a one-stage procedure), and 30 (mild/moderate/severe strictures with infection) with secondary stenting (insertion of the stent after predilation and 2-3 days after nephrostomy). The incidence of complications and procedural costs were compared by a statistical analysis. The primary technical success rate was 98.89%. We did not observe any major complications. The minor complication rate was 11.1%. The incidence of complications for the various techniques was not statistically significantly. The statistical analysis of costs demonstrated that the average cost of secondary stenting (637 euros; SD, 115 euros) was significantly higher than that of procedures which involved direct or primary stenting (560 euros; SD, 108 euros). We conclude that one-step stenting (direct or primary) is a valid option to secondary stenting in correctly selected patients, owing to the fact that when the procedure is performed by expert interventional radiologists there are high technical success rates, low complication rates, and a reduction in costs.

Abstract
The objective of this paper is to assess the feasibility and effectiveness of emergency percutaneous treatment of ruptures of the iliac axis. In 5 years, we observed 13 patients (mean age, 62.1 years), 11 with rupture of the external iliac artery and two with rupture of the common iliac artery (six traumatic and seven iatrogenic). All patients were treated with stent grafts. A follow-up was performed with a color Doppler ultrasound at 1, 3, 6, and 12 months during the first year and then yearly. Immediate technical success was obtained in all cases. During a mean follow-up of 22.3 months, one stent-graft occlusion and one infection of a retroperitoneal hematoma occurred. The primary patency rate is 92.3%. Percutaneous treatment is a feasible and safe tool for iliac axis ruptures because it can provide a fast and definitive exclusion of bleeding with a patency rate comparable to surgery and less major morbidity and mortality.

Abstract
Vascular injuries with acute arterial haemorrhage are rare but the infrequency of these complications may make their diagnosis and treatment challenging for surgeons unfamiliar with their management. In the past, surgery or coil embolisation has been used to treat these lesions; we describe the case of a pseudo-aneurysm of the common femoral artery developed during a total hip arthroplasty, promptly managed with an endovascular stent graft.

Abstract
PURPOSE The purpose of this study was to assess the feasibility and clinical impact of the percutaneous removal and replacement of dysfunctioning plastic biliary endoprostheses (PBE). MATERIALS AND METHODS Over a period of 24 months, we observed eight patients (age 54-82 years; mean 65) with dysfunctioning PBE. After transhepatic cholangiography and bile duct catheterisation, the endoprostheses were grasped with a gooseneck snare and pushed into the duodenum using a long introducer sheath. Subsequently, we implanted six metallic stents in middle and distal occlusions and four plastic endoprostheses in two patients with proximal occlusion. Clinical and ultrasound followup was performed 1, 3 and 6 months after the procedure and then yearly. RESULTS The procedure was technically successful in all patients. No major complication occurred. All patients were discharged without biliary drainage catheters. During the follow-up period (mean: 7.1 months), four patients died and two occlusions of metallic stents were treated by implanting a further metallic stent. CONCLUSIONS Percutaneous removal of a dysfunctioning PBE is feasible and allows better quality of life owing to the absence of biliary drainage. Patency of metallic stents is higher than that of PBE. Larger studies are clearly required to validate this approach.

Abstract
AIM Aorto-iliac obstructive disease has been traditionally treated with endarterectomy and/or a surgical bypass graft. Kissing-stents technique has been proposed to reconstruct the aorto-iliac bifurcation for complex aorto-iliac lesions. METHODS We report 43 patients with complex aorto-iliac occlusions managed with endovascular repair. Between March 1999 and October 2005, a total of 43 patients with a mean age of 66+/-10 years underwent endovascular treatment for aorto-iliac obstructive disease. Lesions were classified C (n=34) and D (n=9), accordingly to the Trans-Atlantic Inter-Society Consensus (TASC) classification. All endovascular interventions were performed in the theatre under regional anesthesia. Predilation with kissing-balloons angioplasty was usually performed; the bifurcation was then eventually reconstructed using bilateral stents placed with the kissing technique. Clinical examination and duplex scans or computed tomography-angiography (CT-A) were performed at discharge and 1, 6, and 12 months after the procedure, with yearly studies thereafter. RESULTS Kissing-stents technique was selectively used in 30 cases (69.7%); the remainder cases were treated with kissing-balloons. Major complications occurred in 2 patients (4.6%). Overall, mean hospitalization was 4.1+/-2.8 days (median 3 days). Mean follow-up was 32.4 months (range 1-84 months; median 36 months). During the follow-up, 2 patients (4.6%) died. Duplex and/or CT-A examination detected 4 re-occlusions. Primary patency rates at 12, 24, and 60 months were 92%, 85.7%, and 80.7%, respectively; overall secondary patency rate was 40/43 patients. CONCLUSIONS We consider this approach most appropriate for patients deemed at high operative risk for conventional repair or for those who refuse surgery.

The haemorrhages could not be treated by local measures, and a transjugular intrahepatic portocaval shunt was performed, displacing an endoprosthesis and a self-expandable stent. We highlight the role of TIPS to treat recurrent bleedings from the stoma in cirrhotic patients with ileal conduit and portal hypertension.

Abstract
AIM Vena cava filters are used for the prevention of pulmonary embolism in cases of contraindication, failure or complications of the anticoagulant therapy. There are no certain data in the literature concerning the effectiveness of vena cava filters and, above all, the possible long-term complications are not known. For this reason increasing attention is paid to permanent/removable filters that permit exploitation of the short-term advantages of vena cava interruption, eliminating the possible long-term complications. We have reported the results of a multicentre experience concerning ALN permanent/removable vena cava filters in a total of 276 patients. METHODS Vena cava filters were placed in 276 patients via the jugular, femoral and brachial vein. The filter was removed in 43 patients after 3 months and in 28 patients after 6 months. RESULTS In 1 case, due to incomplete opening of the filter, immediate percutaneous removal was performed and another filter was positioned. In 5 cases it was not possible to remove the filter, in 1 case due to inexperience and in the remaining cases due to adhesion of the head or claws of the filter to the wall of the vein. No problems occurred in the other cases. CONCLUSIONS The ALN vena cava filter is safe, easy to position and remove even a long time after placement. Currently permanent filters should be used only for patients with poor survival expectancy whereas in all other cases the use of removable filters is preferable.

Abstract
PURPOSE This knowledge will provide an ability to earlier detect bleeding complications after radiofrequency ablation (RFA), to manage these complications appropriately with endovascular procedures and minimize the sequelae. MATERIALS AND METHODS From 2002 to 2005, 96 patients with 150 hepatic tumours underwent 126 RFA sessions. Fifty-eight patients had HCC, 34 had liver colorectal metastases and 4 had cholangiocellular carcinoma. Sixty-one patients were men and 35 were women (mean age 69.82 years, age range 39-89). The lesions number ranged from 1 to 7 per patients (mean 1.6 nodules) with a mean diameter of 28.5 mm (range 80-10 mm). Seventy-seven patients underwent a single ablative session, 13 patients underwent 2 sessions, 4 patients underwent 3 sessions and 2 patients underwent 4 sessions. The number of tumours treated in each ablative session was 1 in 106, 2 in 18 and 4 in 2 patients. RESULTS Two cases of serious haemorrhages occurred after the procedures in two patients treated for liver metastases. An endovascular embolization was proposed for both patients using polyvinyl-alcohol and micro-coils. The absence of bleeding was first confirmed during angiography and then by CT performed the day after the angiographic procedure. CONCLUSION Transarterial embolization (TAE) represents the treatment of choice in the management of iatrogenic bleeding after RFA since it is minimally invasive, have a high success rate and a low incidence of complications compared to the more complex and dangerous surgical or laparoscopic options in patients who are often haemodynamically unstable and therefore at high anaesthetic and surgical risk.

Abstract
OBJECTIVE To report the mid-term results of 63 patients who received a new commercially-available retrievable vena cava filter, ALN. METHODS Between January 2001 and October 2005, 63 patients (mean age 65 +/- 15 years) underwent placement of ALN filters. Filter removal was performed when anti-thrombotic prophylaxis was considered unnecessary or when the patient could safely resume full anticoagulant therapy. RESULTS Thirty-five patients (55%) had ilio-femoral venous thrombosis and 28 patients (45%) had ilio-caval thrombosis. Overall, 49% had pulmonary embolism. Technical success for filter insertion was 100%, without any complications. None of the procedures aborted or was converted due to technical difficulties. After a median follow-up of 21-months (range 1-48, median 18), there were no cases of pulmonary embolism or vena cava thrombosis. Two patients died of a cause unrelated to deep venous thrombosis during the follow-up period, without clinical evidence of pulmonary embolism or filter-associated complications. No device migration was observed. There were 20 (31.7%) retrieval attempts: in 16 cases filters were retrieved successfully, but 4 cases were aborted. The mean implantation period of the retrieved filter was 179 days (range 53-370). CONCLUSION Our results confirm the clinical efficacy of the ALN filter for preventing potentially fatal pulmonary embolism whilst implanted and in absence of post-insertion complications, even when left in place indefinitely.

Abstract
PURPOSE Our aim is to report our experience in the endovascular treatment of steno-occlusions of the infrarenal abdominal aorta. MATERIALS AND METHODS We selected 19 patients (mean age 66.3 years, range 45-80): five with complete occlusion of the infrarenal aorta and both common iliac arteries (CIAs), four of which were associated with occlusion of the external iliac arteries (EIAs); three with complete occlusion and three with severe stenosis of the distal aorta with occlusion or stenosis of the CIAs and EIAs; and eight with focal severe stenosis of the infrarenal aorta. All patients were treated with direct stenting. RESULTS Immediate technical success was 94.7% (18/19 cases). We observed two cases of distal embolism treated with thrombolysis, one case of mild renal failure and one case of transient angina abdominis. During the follow-up (mean 19.6 months; range 6-48), 2/18 (11.1%) occlusions of an iliac stent occurred 1 and 3 months after the procedure (treated with local intra-arterial thrombolysis). The primary patency rate was 88.8% and the secondary patency rate was 100%. CONCLUSIONS Direct stenting is a feasible and safe option for the treatment of infrarenal abdominal aortic steno-occlusions, especially in patients at high surgical risk, with good early and late clinical results.

Abstract
Arteriovenous fistulas (AVFs) are infrequently seen in the civilian health-care system; traditionally, these lesions have been treated with ligation, or direct surgical repair with concomitant revascularization. We describe a rare case of a peroneal AVF treated with a stent-graft.

Abstract
PURPOSE To assess the effectiveness of endovascular treatment of femoropopliteal aneurysms (FPAs). METHODS In the last 5 years, we have treated 17 FPAs (diameter 21-75 cm, mean 38.4 cm; length 27-100 cm, mean 72.5 cm) in 15 patients (age 57-80 years, mean 70.9 years). The diagnosis was obtained by color Doppler ultrasound (CDU) and the procedure was planned by CT angiography (CTA) and preprocedural angiography. Eight FPAs were excluded with only one stent-graft; in 8 patients, two stent-grafts were positioned; and in 1 patient, three stent-grafts were used. In 14 cases we used a Wallgraft endoprosthesis, in 2 cases a Hemobahn, and in 1 case an Excluder contralateral leg. The patients were followed up with CDU and occasionally with CTA. RESULTS Immediate technical success was obtained in 17 of 17 cases (100%). One patient died during the first year. During a mean follow-up of 26.9 months (range 3-60 months) we observed 6 of 16 (38%) stent-graft occlusions (3 of which were recanalized with locoregional thrombolysis and 3 with mechanical thrombectomy). Two stent-grafts were patent at 12 and 24 months. Four patients experienced subsequent occlusions and recanalizations until corrected by surgical bypass (1 at 14 months, 2 at 18 months, and 1 at 36 months). Therefore the primary patency was 63% and assisted patency was 73%. CONCLUSION The endovascular approach is a minimally invasive treatment option for FPAs. Moreover endovascular stent-grafting does not necessarily preclude conventional surgical repair, but it can delay it. Longer follow-up will be needed to determine the long-term patency rate.

Abstract
PURPOSE Our aim is to verify the feasibility and effectiveness of endovascular treatment for symptomatic abdominal aortic aneurysms (AAAs) in urgencies and emergencies. MATERIALS AND METHODS Over the past 51 months, we treated 38 symptomatic AAAs with endovascular exclusion. In 23 haemodynamically stable patients, computed tomography (CT) angiography was performed before treatment, and AAA exclusion was carried out as an urgent procedure; 15 patients with haemorrhagic shock were examined by ultrasound (US) only in the emergency room whereas the procedure was carried out in emergency and planned using angiography. Time from presentation to treatment was 100 min on average (range: 50-150 min). We used 27 Excluder (Gore) and 11 Zenith (Cook) stentgrafts. The follow-up was performed with CT angiography after 1, 3, 6 and 12 months and yearly thereafter. RESULTS The immediate technical success rate was 100%, and the perioperative mortality rate was 10.5%. At follow-up completed in 34 patients (range: 1-48 months, mean: 19.2), we observed five endoleaks (14%) (four type 2: two thrombosed spontaneously and two were under observation at the time of writing; one type 3, treated with stent-graft extension) and one occlusion of a stentgraft leg (treated by femorofemoral bypass). CONCLUSIONS Endovascular treatment of AAAs is a good therapeutic alternative even in urgency and emergency conditions where correct planning ensures technical results comparable with those obtained under elective conditions.

Abstract
The purpose of the study was to assess the effectiveness of contrast-enhanced ultrasonography (CEUS) in endoleak classification after endovascular treatment of an abdominal aortic aneurysm compared to computed tomography angiography (CTA). From May 2001 to April 2003, 10 patients with endoleaks already detected by CTA underwent CEUS with Sonovue to confirm the CTA classification or to reclassify the endoleak. In three conflicting cases, the patients were also studied with conventional angiography. CEUS confirmed the CTA classification in seven cases (type II endoleaks). Two CTA type III endoleaks were classified as type II using CEUS and one CTA type II endoleak was classified as type I by CEUS. Regarding the cases with discordant classification, conventional angiography confirmed the ultrasound classification. Additionally, CEUS documented the origin of type II endoleaks in all cases. After CEUS reclassification of endoleaks, a significant change in patient management occurred in three cases. CEUS allows a better attribution of the origin of the endoleak, as it shows the flow in real time. CEUS is more specific than CTA in endoleak classification and gives more accurate information in therapeutic planning.

Abstract
In the past few years, major improvements and new technologies have been proposed and applied in esophageal surgery. Its evolution depended not only on a thorough knowledge of surgical anatomy and technique, but also on important developments in pre- and postoperative care. Esophageal resection for cancer is still associated with high morbidity and mortality. Postoperative complications may be either patient or surgeon related. Patient-related factors include age, malnutrition, immunodepression and associated diseases. The surgeon-related factors are surgical experience, hospital volume and multidisciplinary approach. Preoperative evaluation is defined as the process of clinical assessment that precedes the delivery of anesthesia. The principle is to gain information concerning patients that leads to modification of their management, and improves the outcome from surgery.

Abstract
BACKGROUND This study aimed to assess the feasibility and short-term results for percutaneous radiofrequency ablation in the treatment of primary and secondary lung tumors. METHODS Between May 2003 and July 2004, 15 patients (mean age, 64.9 years; range, 51-80 years) with 18 pulmonary lesions (9 primitive non-small cell lung cancers and 9 metastases) underwent the ablation procedure. All the patients had absolute contraindications to the surgery. The procedure was performed under computed tomography (CT) guidance with anesthesiologic assistance using a coaxial Le Veen needle electrode. The results were evaluated by postprocedural CT scan, and then by clinical and laboratory examination and CT scan 1, 3, 6, 9, and 12 months after the treatment. RESULTS A complete ablation was obtained for 16 of 18 lesions (88.9%), and a partial ablation was achieved for the remaining 2 lesions (central tumors). In terms of complications, there were five cases of pneumothorax (2 resolved spontaneously and 3 were drained through a coaxial needle), four middle pleural reactions, and one hemothorax that required draining surgically. Follow-up evaluation was performed for 16 of 18 lesions. Stability was observed in one of two central tumors that received partial ablation. The remaining 15 tumors that received a complete ablation were followed up for a mean of 5 months (range, 1-12 months). All 15 lesions appeared to be hypodense at the CT examination. Dimension reduction with progressive fibrotic scar formation was observed in seven of seven lesions during a follow-up period of 6 months or more. A recurrence at the site of the treatment for two of three lesions was observed during a 12-month follow-up period. One of these received a second radiofrequency ablation. Five patients experienced systemic disease progression. In four of these five patients, this progression was not associated with recurrence at the site of the treatment. CONCLUSION Radiofrequency ablation seems to be possible for "nonsurgical" patients with primary and secondary lung tumors. Good results in terms of local tumor control were observed during short-term follow-up evaluation.
