Endovascular treatment of cerebral aneurysms with detachable coils has now been proved to be a superior alternative to open microsurgery in terms of survival free of disability at one year according to the recently published large randomized International Subaracnoid Aneurysm Trial (ISAT). However, aneurysm recanalization secondary to coil compaction is still the main problem of this technique observed in the follow-up period but treatment strategies for these regrowths are not yet well established. We present two interesting cases in which we observed a significant aneurysm recanalization at six month control angiography that was found to be spontaneously thrombosed in the late follow-up angiograms at the second and fifth years consecutively.

The Stability

The long-term outcome of detachable coil embolization of cerebral aneurysms is still unknown. The purpose of this study was to evaluate the stability of the anatomic occlusion of aneurysms treated with the Cook detachable coil system and assess the rate of recanalization and recurrence. A study involving 250 patients with 271 ruptured aneurysms treated with the Cook detachable system between January 1997 and September 2003 who subsequently underwent six month, one year and two year follow-up angiography were enrolled in the study. Angiographic findings were reviewed to determine the percentage of aneurysm occlusion. Long-term follow-up angiograms (at two years) demonstrated complete occlusion in 75% of cases, and subtotal occlusion in 25% of cases. Overall morbidity was 7.3%, aneurysm recurrence 3.2%, and aneurysm re-treatment 3.2%. Recurrent subarachnoid hemorrhage occurred in only one patient. Angiographic follow-up demonstrated the stability and durability of treatment with the Cook detachable coil system.

Summary. Background: To assess the impact of short- vs. long-term anticoagulation in addition to standard dual antiplatelet therapy (DAPT) upon endovascular treatment of (sub)acute thrombembolic occlusions of the lower extremity. Patient and methods: Retrospective analysis was conducted on 202 patients with a thrombembolic occlusion of lower extremities, followed by crirical limb ischemia that received endovascular treatment including thrombolysis, mechanical thrombectomy, or a combination of both between 2006 and 2015 at a single center. Following antithrombotic regimes were compared: 1) dual antiplatelet therapy, DAPT for 4 weeks (aspirin 100 mg/d and clopidogrel 75 mg/d) upon intervention, followed by a lifelong single antiplatelet therapy; 2) DAPT plus short term anticoagulation for 4 weeks, followed by a lifelong single antiplatelet therapy; 3) DAPT plus long term anticoagulation for > 4 weeks, followed by a lifelong anticoagulation. Results: Endovascular treatment was associated with high immediate revascularization (> 98 %), as well as overall and amputation-free survival rates (> 85 %), independent from the chosen anticoagulation regime in a two-year follow up, p > 0.05. Anticoagulation in addition to standard antiplatelet therapy had no significant effect on patency or freedom from target lesion revascularization (TLR) 24 months upon index procedure for both thrombotic and embolic occlusions. Severe bleeding complications occurred more often in the long-term anticoagulation group (9.3 % vs. 5.6 % (short-term group) and 6.5 % (DAPT group), p > 0.05). Conclusions: Our observational study demonstrates that the choice of an antithrombotic regime had no impact on the long-term follow-up after endovascular treatment of acute thrombembolic limb ischemia whereas prolonged anticoagulation was associated with a nominal increase in severe bleeding complications.

We evaluated long-term angiographical follow-up of cerebral aneurysms treated with detachable platinum coils with special reference to the long-term morphological outcomes of incompletely obliterated aneurysms. Serial long-term follow-up cerebral angiograms (>1 year) were obtained in 47 cases out of 134 cases treated with GDCs or IDCs from 1994 to 1999. In 47 patients, intial angiographical results demonstrated ten complete aneurysmal occlusion, seven aneurysms with a small neck remnant, twenty aneurysms with body filling and ten aneurysms with both of neck remnant and body filling. In the ten completely obliterated aneurysms, follow-up angiograms revealed no aneurysmal recanalization. In seven aneurysms with neck remnant, three remained unchanged, four showed enlargement of contrast filling in the part of the neck of the aneurysm. In twenty aneurysms with body filling, five had developed into complete obliteration, three remained unchanged, 11 had recanalization, and one aneurysm displayed regrowth. In ten aneurysms with both of neck remnant and body filling, two remained unchanged, five had recanalization, and three aneurysms displayed regrowth. Long-term angiographical follow-up results are less satisfactory in cases involving incompletely obliterated lesions. A higher incidence of recanalizations were promoted in cases with neck remnant and/or body filling. Strict follow-up angiography is mandatory when a complete obliteration is not achieved.

This study reviewed the short-term outcome of transcatheter closure of the defects within the oval fossa using an Amplatzer® Septal Occluder. From January 1997 to December 2000, 210 patients with defects within the oval fossa underwent successful transcatheter closure. We reviewed a total of 190 patients with left-to-right shunts, assessing the patients for possible complications and the presence of residual shunts using transthoracic echocardiogram at 24 h, 1 month, 3 months and one year. Their median age was 10 years, with a range from 2 to 64 years, and their median weight was 23.9 kg, with a range from 8.9 to 79 kg. In 5 patients, a patent arterial duct was closed, and in 2 pulmonary balloon valvoplasty performed, at the same sitting. The median size of the Amplatzer® device used was 20 mm, with a range from 9 to 36 mm. The median times for the procedure and fluoroscopy were 95 min, with a range from 30 to 210 min, and 18.4 min, with a range from 5 to 144 min, respectively. Mean follow-up was 20.8 ± 12.4 months. Complete occlusion was obtained in 168 of 190 (88%) patients at 24 h, 128 of 133 (96.2%) at 3 months, and 103 of 104 (99%) at one year. Complications occurred in 4 (2.1%) patients. In one, the device became detached, in the second the device embolized into the right ventricular outflow tract, the lower end of the device straddled in the third, and the final patient had significant bleeding from the site of venupuncture. There were no major complications noted on follow-up. We conclude that transcatheter closure of defects within the oval fossa using the Amplatzer® Septal Occluder is safe and effective. Long-term follow-up is required, nonetheless, before it is recommended as a standard procedure.

Long-term follow-up studies after endovascular treatment for intracranial aneurysm are still rare and inconclusive. The aim of this study was to assess the long-term clinical and angiographic outcome of patients with endovascularly treated aneurysms. The clinical outcome of all 185 patients with endovascularly treated aneurysms were analyzed and 77 out of 122 surviving patients were examined with MRI and MRA nine to 16 years (mean 11 years) after the initial endovascular treatment. Sixty-three patients were deceased at the time of follow-up. The cause of death was aneurysm-related in 34 (54%) patients. The annual rebleeding rate from the treated aneurysms was 1.3% in the ruptured group and 0.1% in the unruptured group. In long-term follow-up MRA 18 aneurysms (53%) were graded as complete, 11 aneurysms (32%) had neck remnants and five aneurysms (15%) were incompletely occluded in the ruptured group. The occlusion grade was lower in the unruptured group with 20 aneurysms (41%) graded as complete, 11 (22%) had neck remnants and 18 (37%) were incomplete. However, only three aneurysms were unstable during the follow-up period and needed retreatment. Endovascular treatment of unruptured aneurysms showed incomplete angiographic outcome in 37% of cases. However, the annual bleeding rate was as low as 0.1%. Endovascular treatment of ruptured aneurysms showed incomplete angiographic outcome in 15% of cases and the annual rebleeding rate was 1,3%.

Objectives: The aim of this study was to determine the mechanisms and effectiveness of pulmonary antrum radial-linear (PAR) ablation in comparison with pulmonary vein isolation (PVI) in patients with paroxysmal atrial fibrillation (AF) after a long-term follow-up. Background: The one-year follow up data suggested that PAR ablation appeared to have a better outcome over the conventional PVI for paroxysmal AF. Methods: The enrollment occurred between March, 2011, and August, 2011, with the last follow-up in May, 2014. A total of 133 patients with documented paroxysmal AF were enrolled from 5 centers and randomized to PAR group or PVI group. Event ECG recorder and Holter monitoring were conductedduring the follow-up for all patients. Results: The average procedure time was 151±23 min in PAR group and 178±43 min in PVI group ( P <0.001). The average fluoroscopy time was 21±7 min in PAR group and 27±11 min in PVI group ( P= 0.002). AF triggering foci were eliminated in 59 patients (89.4%) in PAR group, whereas, only 4 patients (6.0%) in PVI group (P<0.001).At median 36 (37-35) months of follow-up after single ablation procedure, 43 of 66 patients in PAR group (65%) and 28 of 67 patients in PVI group (42%) had no recurrence of AF off antiarrhythmic drug (AAD) (P=0.007); and 47 of 66 patients in PAR group (71%) and 32 of 67 patients in PVI group (48%) had no recurrence of AF with AAD (P=0.006). At the last follow-up, the burden of AF was significantly lower in PAR group than in PVI group (0.9% ± 2.3% vs 4.9% ± 9.9%;90th percentile, 5.5% vs 19.6%; P=0.008). No major adverse event (death, stroke, PV stenosis) was observed in all the patients except one case of pericardial tamponade. Conclusions: PAR ablation is a simple, safe, and effective strategy for the treatment of paroxysmal AF with better long-term outcome than PVI. PAR ablation might exhibit the beneficial effect on AF management through multiple mechanisms. Registration: ChiCTR-TRC-11001191

Meningiomas are uncommon tumors in children and either more rarely encountered in the pineal region. We report two cases of meningioma of the pineal region in children. One of these cases was a five years-old girl and the other a one year-old boy. No specific clinical presentation or tomographic examinations findings was identified before treatment, suggestive of a diagnosis of menigioma. The clinical and laboratory features were very similar to the most common tumors of the pineal region. Prior to the surgery, the histology of these tumors was not suspected. Both patients underwent direct surgery and complete removal was achieved by a suboccipital transtentorial approach. The tumors originated from velum interpositum in both cases. At the follow up, one case presented with recurrence six years later, and she underwent a reoperation with total resection without morbidity. Long-term follow up presented no other recurrences.
