Materials and methods: Between May 2000 and June 2003 we treated 11 true SAAs in 9 patients (7 females and 2 males; mean age 58 years), 8 saccular and 3 fusiform, 4 located at the middle tract of the splenic artery, 5 at the distal tract and 2 intra-parenchymal. The diagnosis was performed with colour-Doppler ultrasound and/or CT-angiography; 7 patients were symptomless, 1 had left hypochondriac pain, and 1 had acute abdomen caused by a ruptured SAA. Four SAAs were treated by microcoil embolization of the aneurysmal sac with preservation of splenic artery patency; in 2 cases this was associated with transcatheter injection of N-butyl-2-cyanoacrylate. Four cases were treated by endovascular ligature, with sectoral spleen ischaemia. One ruptured SAA received emergency treatment with splenic artery cyanoacrylate embolization. Two intra-parenchymal SAAs were excluded, one by cyanoacrylate embolization of the afferent artery and the other by transcatheter thrombin injection in the aneurysmal sac. Results: Technical success was observed in all cases (in 10/11 at the end of the procedure; in 1/11 at CT performed 3 days after the procedure). The follow-up (mean 18 months; range 6-36) was performed by colour-Doppler ultrasound and/or CT-angiography 3, 6 and 12 months after the procedure and subsequently once a year; the complete exclusion of the aneurysms was confirmed in 11/11 cases. The complications were: 4 cases of mild left pleuritis; fever and left hypochondriac pain 1 day after the procedure (in the same 4 patients and in one other case); 5 cases of sectoral spleen ischaemia and 1 case of diffuse spleen infarction with partial revascularization by collateral vessels. No alteration of the levels of pancreatic enzymes was found; a transitory increase in platelet count occurred only in the patient with diffuse spleen infarction. Conclusions: Using different techniques, endovascular treatment is feasible in nearly all SAAs. It ensures good immediate and long term results, and no doubt presents some advantages in comparison to surgical treatment, as it is less invasive and allows the preservation of splenic function.

Among the various therapies, local radiotherapy is the gold standard for pain palliation from single metastasis, even though the maximum benefit is obtained between 12 and 20 weeks from initiation. In carefully selected patients, several ablation therapies achieve this objective in 4 weeks. The purpose of this study was to assess the technical success, effectiveness and possible complications of percutaneous ablation therapies in patients with symptomatic bone metastases. From November 2003 to May 2008, ten ablation treatments were performed in ten patients with acute pain from metastatic bone lesions. Patient selection and choice of the most appropriate ablation treatment was made based on lesion characteristics. Three patients were treated with radiofrequency, one with plasma-mediated radiofrequency, two with plasma-mediated radiofrequency and cementoplasty, three with radiofrequency and cementoplasty and one with microwave. Assessments were based not only on imaging but also on the visual analogue scale (VAS) score for determining pain and on changes in morphine-equivalent doses. In both cases, 3-month follow-up showed a statistically significant reduction of pain. In no case did local complications occur either during or after treatment. Only one patient treated with radiofrequency (1/9, 11%) developed low-grade fever and general malaise during the 6 days following the procedure, compatible with a post-radiofrequency syndrome, which was treated with acetaminophen (paracetamol) only and resolved on day 7. Percutaneous ablation therapies represent a safe and valuable alternative for treating localised pain from single bone metastasis, providing rapid (4-week) relief of symptoms and a significant reduction in morphine doses. This contributes to improving the quality of life of patients with metastatic disease.

In the last year, two male patients with AAAs, treated 8 and 23 months ago with bifurcated stent-graft, were observed because of lumbar pain and hemorragic shock. Multidetector computed tomography (MDCT) showed a retroperitoneal hematoma; in both cases a type III endoleak was detected, in one case associated with a type II endoleak from the iliolumbar artery. The procedures were performed in the theater, in emergency. Type II endoleak was treated with transcatheter superselective glue injection; type III endoleaks were excluded by a stent-graft extension. The procedures were successful in both patients, with immediate hemodynamic stabilization. MDCT after the procedure showed complete exclusion of the aneurysms. In conclusion, endovascular treatment is a safe and feasible option for the treatment of ruptured AAAs previously treated by EVAR; this approach allows avoidance of surgical conversion, which is technical very challenging, with a high morbidity and mortality rate.
