ObjectTo report the morbidity and long term results in the treatment of paragangliomas by transarterial embolization with ethylene vinyl alcohol (Onyx), either as preoperative or palliative treatment.MethodsBetween September 2005 and 2012, 18 jugulotympanic, 7 vagal, and 4 carotid body paragangliomas (CBPs) underwent Onyx embolization, accordingly to our head and neck multidisciplinary team's decision. CBPs were embolized preoperatively. Jugulotympanic and vagal paragangliomas underwent surgery when feasible, otherwise palliative embolization was carried out alone, or in combination with radiotherapy or tympanic surgery in the case of skull base or tympanic extension. Treatment results, and clinical and MRI follow-up data were recorded.ResultsIn all cases, devascularization of at least 60% of the initial tumor blush was obtained; 6 patients underwent two embolizations. Post-embolization, 8 patients presented with cranial nerve palsy, with partial or complete regression at follow-up (mean 31 months, range 3–86 months), except for 2 vagal and 1 hypoglossal palsy. 10 patients were embolized preoperatively; 70% were cured after surgery and 30% showed residual tumor. 19 patients received palliative embolization, of whom 5 underwent radiotherapy and 3 received tympanic surgery post-embolization. Long term follow-up of palliative embolization resulted in tumor volume stability (75%) or extension in intracranial or tympanic compartments. Onyx embolization of CBPs resulted in more difficult surgical dissection in 2 of 4 cases.ConclusionsOnyx embolization is a valuable alternative to surgery in the treatment of jugulotympanic and vagal paragangliomas; tympanic surgery or radiosurgery of the skull base should be considered in selected cases. Preoperative Onyx embolization of CBPs is not recommended.

PURPOSE: Large skull-base meningiomas are difficult to treat due to their proximity or adherence to critical structures. We analyzed the long-term results of patients with skull-base meningiomas treated by a new approach with high-precision fractionated stereotactic radiotherapy. PATIENTS AND METHODS: One hundred eighty-nine patients with benign meningiomas were treated with conformal fractionated stereotactic radiotherapy between 1985 and 1998. Patients were undergoing a course of radiotherapy either as primary treatment, following subtotal resection, or for recurrent disease. The median target volume was 52.5 mL (range, 5.2 to 370 mL). The mean radiation dose was 56.8 Gy (± 4.4 Gy). Follow-up examinations, including magnetic resonance imaging, were performed at 6-month intervals thereafter. RESULTS: The median follow-up period was 35 months (range, 3 months to 12 years). Overall actuarial survival for patients with World Health Organization (WHO) grade I meningiomas was 97% after 5 years and 96% after 10 years. Local tumor failure was observed in three of 180 patients with WHO grade I tumors and was significantly higher in two of nine patients with WHO grade II tumors. A volume reduction of more than 50% was observed in 26 patients (14%). Preexisting cranial nerve symptoms resolved completely in 28% of the patients. Clinically significant treatment-induced toxicity was seen in 1.6% of the patients. No treatment-related deaths occurred. CONCLUSION: The results of this study demonstrate that fractionated stereotactic radiotherapy is safe and effective in the therapy of subtotally resected or unresectable meningiomas. The overall morbidity and incidence subacute and late side effects of this conformal radiotherapy approach were low.

Objective To evaluate the long-term efficacy and safety of selective arterial embolization (SAE) in the treatment of renal angiomyolipomas (AMLs). Methods This was a retrospective review of medical records and imaging findings from patients with renal AMLs who attended our clinic and received SAE between January 2007 and January 2014. Only patents with complete medical records, preoperative computed tomography scans using typical imaging and follow-up data were included. Results A total of 79 patients were enrolled in the study. Technical and clinical success rates were 100% and 91% ( n = 72), respectively. Only two patients experienced major complications. Post-embolization syndrome (i.e. fever, abdominal pain, nausea or vomiting) was reported in 68 (86%) patients, but all symptoms were mild and resolved with conservative measures. Mean radiological and clinical follow-up periods were 16.8 and 35.9 months, respectively. In 75 (95%) patients, tumours decreased in size; mean ± SD tumour size significantly decreased from 8.4 ± 3.5 cm pre-embolization to 6.7 ± 3.0 cm post-embolization . Conclusions This study provides long-term evidence that SAE is a safe and effective method in the treatment of patients with renal AMLs.

Gamma knife radiosurgery (GKRS) is well-established in the management of inaccessible, recurrent, or residual benign skull base meningiomas. Most series report clinical outcome parameters and complications in the short -intermediate period after radiosurgery. Reports of long-term tumor control and neurological status are still lacking. Objective: We report the presentation, treatment, and long-term outcome of skull base meningiomas after GKRS. Methods: From a prospectively collected IRB approved database, we selected patients with a WHO grade I skull base meningioma treated with a single-session GKRS and a minimum of 60 months follow up. 135 patients, 54.1% males (n=73) form the cohort. Median age was 54 years (19-80). Median tumor volume was 4.7 cm3 (0.5-23). Median margin dose was 15 Gy (7.5-36). Median follow up was 102.5 months (60.1-235.4). Patient and tumor characteristics were assessed to determine predictors of neurological function and tumor progression. Results: At last follow up, tumor volume control was achieved in 88.1% (n=119). Post-GKRS clinical improvement or stability was reported in 61.5%. The 5, 10, and 15 years actuarial progression free survival rates are 100%, 95.4%, and 68.8%, respectively. Favorable outcome (both tumor control and clinical preservation/improvement) was attained in 60.8% (n=79). Pre-GKRS performance status (KPS) was shown to influence tumor progression (p=0.0001) and post-GKRS clinical improvement / preservation (p=0.003). Conclusion: GKRS offers a highly durable rate of tumor control for WHO-I skull base meningiomas, with an acceptably low incidence of neurological deficits. KPS at the time of radiosurgery serves as a reliable long-term predictor of overall outcome.

Abstract Purpose To evaluate the feasibility, safety and long-term efficacy of super-selective trans-catheter arterial embolization for the management of intractable bladder bleeding. Materials and methods The records of 20 patients with intractable haematuria referred urgently for selective arterial embolization after failed conventional therapy, between 2013 and 2018, were retrospectively analyzed. Primary outcomes were technical (cessation of extravasation and/or stasis of flow within the target vessel) and clinical (bleeding control) success. Secondary outcomes included complication and re-intervention rates. Results Technical success was 90% (18/20 cases), as in 2 cases, embolization was not feasible. Super-selective embolization of the vesical arteries was feasible in 15/18 cases (83.3%). Selective proximal occlusion of the anterior division of the internal iliac artery was performed in two cases (11%) and embolization of the anterior division after coil blockage of the posterior division was performed in one case (5%). Bilateral and unilateral embolization was performed in 10 and 8 cases, respectively. Peri-procedural mortality rate was 5% (1/18 patients). One possible procedure-related death occurred due to myocardial infarction ten days following non-target embolization of the buttocks and the anterior abdominal wall. Mean time follow up was 35 ± 15 months. Bleeding reoccurred in three patients (16.6%), all successfully managed (one conservatively and two with further embolization). Clinical success was 85% (17/20 cases). During follow up 11 more patients died, due to underlying conditions not related to bleeding or the procedure. Conclusions Super-selective angiographic embolization is feasible, safe and effective to control refractory, life threatening bladder bleeding and should be considered as a first line treatment, as to obviate the need for emergency surgery.

✓ Transarterial embolization of direct carotid—cavernous fistulas (CCFs) using detachable balloons is the best initial option for occlusion of the fistula and preservation of the internal carotid artery. However, the long-term safety and efficacy of this treatment is unknown. The authors reviewed the long-term outcome of 87 patients with 88 direct CCFs occluded by detachable balloons. Clinical follow up was obtained in 48 (83%) of 58 patients treated with latex balloons (mean follow-up period 10 years, range 5.9–15.5 years) and 28 (97%) of 29 patients treated with silicone balloons (mean follow-up period 4 years, range 1–6.6 years). Two patients were treated with both balloon types. There were no late recurrent symptoms of cranial bruit, proptosis, chemosis, or arterialized conjunctiva in patients treated with either latex or silicone balloons. Diplopia improved in all patients; however, five patients required shortening of the lateral rectus muscle. Delayed ischemia occurred in three patients: one patient had a transient ischemic episode 5 years after treatment with latex balloons and two patients (85 and 90 years old) who had ruptured spontaneous intracavernous aneurysms suffered cerebral infarctions 6 weeks and 4 months, respectively, after treatment with silicone balloons. There were five deaths in the series unrelated to balloon treatment. These results show that after transarterial embolization of direct CCFs using either silicone or latex detachable balloons, the long-term risks are low for fistula recurrence, symptomatic foreign body reaction, symptomatic pseudoaneurysm formation, and cerebral ischemia.

<b><i>Introduction:</i></b> The purpose of this study was to evaluate the effectiveness and long-term results of selective transarterial iliac embolization (STIE) in patients with intractable bladder haemorrhage (IBH). <b><i>Methods:</i></b> Twenty-five patients with a median age of 84 (range 65–94) years underwent STIE because of IBH between 2002 and 2020. The median follow-up time was 3 (mean 13.9) months. Patients were treated because of bleeding bladder or prostate cancer, radiation-induced haemorrhagic cystitis, and other conditions. Success was defined as technical success (feasibility to embolize bilateral hypogastric arteries or neoplastic arteries) and as clinical success (absence of further or additional therapy). <b><i>Results:</i></b> Twenty-five patients with a median age of 84 years with a median hospital stay of 7 days were embolized at our institution. In total, 60% required additional therapy. Only 20% had minor complications, but no complication major was seen; 60% needed an additional therapy because of continuous bleeding. Our 30-day, 90-day, 6-month, and 12-month mortality rates were 28, 44, 64, and 76%, respectively. <b><i>Conclusions:</i></b> STIE in IBH is a safe, well-tolerated, and feasible procedure for palliating haematuria patients in poor general condition. Major complications are very rarely seen. However, patients often need additional therapy after STIE.

Abstract. Background: The technical and clinical outcomes of catheter-directed embolization for peripheral arteriovenous malformations (AVM) using Onyx® (ethylene-vinyl alcohol copolymer) are not well documented. The purpose of this study was to retrospectively assess the safety, technical outcomes and clinical outcomes of catheter-directed Onyx® embolisation for the treatment of symptomatic peripheral AVMs. Patients and methods: Demographics, (pre-)interventional clinical and radiological data were assessed. Follow-up was based on hospital medical records and telephone calls to the patients’ general practitioners. Radiological success was defined as complete angiographic eradication of the peripheral AVM nidus. Clinical success was defined as major clinical improvement or complete disappearance of the initial symptoms. Results: 25 procedures were performed in 22 patients. The principal indications for treatment were pain (n = 10), limb swelling (n = 6), recurrent bleeding (n = 2), tinnitus (n = 3), and exertional dyspnoea (n = 1). Complete radiological success was obtained in eight patients (36 %); near-complete eradication of the nidus was achieved in the remaining 14 patients. Adjunctive embolic agents were used in nine patients (41 %). Clinical success was observed in 18 patients (82%). Major complications were reported in two patients (9 %). During follow-up, seven patients (32 %) presented with symptom recurrence, which required additional therapy in three patients. Conclusions: Catheter-directed embolisation of peripheral AVMs with Onyx® resulted in major clinical improvement or complete disappearance of symptoms in the vast majority of patients, although complete angiographic exclusion of the AVMs occurred in only a minority of patients.

Background: To evaluate safety, short and long-term graft patency, clinical success rates, and factors associated with patency, limb salvage and mortality after surgical reconstruction in patients younger than 50 years of age who had undergone unilateral iliac artery bypass surgery. Patients and methods: From January 2000 to January 2010, 65 consecutive reconstructive vascular operations were performed in 22 women and 43 men of age < 50 years with unilateral iliac atherosclerotic lesions and claudication or chronic limb ischemia. All patients were followed at 1, 3, 6, and 12 months after surgery and every 6 months thereafter. Results: There was in-hospital vascular graft thrombosis in four (6.1 %) patients. No in-hospital deaths occurred. Median follow-up was 49.6 ± 33 months. Primary patency rates at 1-, 3-, 5-, and 10-year were 92.2 %, 85.6 %, 73.6 %, and 56.5 %, respectively. Seven patients passed away during follow-up of which four patients due to coronary artery disease, two patients due to cerebrovascular disease and one patient due to malignancy. Limb salvage rate after 1-, 3-, 5-, and 10-year follow-up was 100 %, 100 %, 96.3 %, and 91.2 %, respectively. Cox regression analysis including age, sex, risk factors for vascular disease, indication for treatment, preoperative ABI, lesion length, graft diameter and type of pre-procedural lesion (stenosis/occlusion), showed that only age (beta - 0.281, expected beta 0.755, p = 0.007) and presence of diabetes mellitus during index surgery (beta - 1.292, expected beta 0.275, p = 0.026) were found to be significant predictors of diminishing graft patency during the follow-up. Presence of diabetes mellitus during index surgery (beta - 1.246, expected beta 0.291, p = 0.034) was the only variable predicting mortality. Conclusions: Surgical treatment for unilateral iliac lesions in patients with premature atherosclerosis is a safe procedure with a low operative risk and acceptable long-term results. Diabetes mellitus and age at index surgery are predictive for low graft patency. Presence of diabetes is associated with decreased long-term survival.

Objective: Approximately one out of five patients with Graves' disease (GD) undergoes a thyroidectomy after a mean period of 18 months of medical treatment. This retrospective and non-randomized study from a teaching hospital compares short- and long-term results of total (TT) and subtotal thyroidectomies (ST) for this disease. Methods: From 1987 to 1997, 94 patients were operated for GD. Thirty-three patients underwent a TT (mostly since 1993) and 61 a ST (keeping 4 to 8 grams of thyroid tissue - mean 6 g). All patients had received propylthiouracil and/or neo-mercazole and were in a euthyroid state at the time of surgery; they also took potassium iodide (lugol) for ten days before surgery. Results: There were no deaths. Transient hypocalcemia (< 3 months) occurred in 32 patients (15 TT and 17 ST) and persistent hypocalcemia in 8 having had TT. Two patients developed transient recurrent laryngeal nerve palsy after ST (< 3 months). After a median follow-up period of seven years (1-15) with five patients lost to follow-up, 41 patients having had a ST are in a hypothyroid state (73%), thirteen are euthyroid (23%), and two suffered recurrent hyperthyroidism, requiring completion of thyroidectomy. All 33 patients having had TT - with follow-ups averaging two years (0.5-8) - are receiving thyroxin substitution. Conclusions: There were no instances of persistent recurrent laryngeal nerve palsy in either group, but persistent hypoparathyroidism occurred more frequently after TT. Long after ST, hypothyroidism developed in nearly three of four cases, whereas euthyroidy was maintained in only one-fourth; recurrent hyperthyroidy was rare.
