Flow Diverting Stent

Background and Purpose: Flow diverting stents are designed to divert blood flow from the aneurysm sac, allowing for eventual occlusion following endovascular therapy. This case series reports clinical experience using the Silk Vista Baby (SVB, Balt Extrusion, Montmorency, France), a flow diverter (FD) designed to treat intracranial aneurysms in small, distal vessels.Methods: All patients who underwent treatment with SVB at the University Hospital “Santa Maria della Misericordia” of Udine between July 2018 and September 2020 were retrospectively identified. Baseline patient and aneurysm characteristics, intraprocedural technical outcomes, periprocedural complications, modified Rankin Scale (mRS) at discharge, magnetic resonance imaging (MRI) results at 3-month follow-up, and angiographic results at 6-month follow-up were collected.Results: A total of 18 patients (55.6% [10/18] male; mean age 62.6 years, range: 42–77 years) were retrospectively identified, receiving treatment for 22 aneurysms. Most patients were symptomatic (14/18, 77.8%) and approximately half had subarachnoid hemorrhage (10/18, 55.6%). Sufficient aneurysm coverage was achieved in 88.9% (16/18) of patients with a single device. Mortality did not occur (0/18, 0%); adverse device-related events included side branch occlusion (1/18, 5.6%) and in-stent thrombosis (1/18, 5.6%). At discharge, 77.8% (14/18) had an mRS of 0. In most cases, patients showed complete occlusion (10/15, 66.7%) or a small aneurysmal remnant (3/15, 20.0%) upon MRI; upon angiography, most showed complete occlusion (10/13, 76.9%) or only a small aneurysmal remnant (2/13, 15.4%).Conclusion: This case series showed that the SVB FD is safe and feasible to use in patients with aneurysms in small, distal vessels. Additional randomized, prospective studies with larger cohorts are needed for the SVB.

OBJECTIVE The aim of this study was to describe the first case series in which an exclusive endoscopic transcanal transpromontorial approach (EETTA) was used to treat small vestibular schwannomas (VSs) and meningiomas of the internal auditory canal (IAC). METHODS The authors performed a retrospective review of patients who had undergone surgery using an EETTA to the IAC at 2 university tertiary care referral centers during the period from November 2011 to January 2015. RESULTS Ten patients underwent surgery via an EETTA for the treatment of VS in the IAC at the University Hospital of Modena or the University Hospital of Verona. The patients had Koos Grade I or II tumors and American Academy of Otolaryngology–Head and Neck Surgery (AAO-HNS) Class D hearing status preoperatively. Gross-total resection was achieved in all patients. No major complications such as cerebrospinal fluid leakage or hemorrhage were reported. In 7 of 10 (70%) patients, facial nerve function was normal immediately after surgery (Rough Grading System [RGS] Grade I). Two patients presented with a transitory facial palsy immediately after surgery (RGS Grade II–III) but experienced complete recovery during the follow-up period. The mean follow-up was 10 months. CONCLUSIONS The EETTA proved to be successful for the removal of VS or meningioma involving the cochlea, fundus, and IAC, with possible lower complication rates and less invasive procedures than those for traditional microscopic approaches. The potential for the extensive and routine use of this approach in lateral and posterior skull base surgery will depend on the development of technology and surgical refinements and on the diffusion of skull base endoscopic skills among the otolaryngological and neurosurgical communities.

We assessed the outcomes of the use of anterior chamber foldable lens for unilateral aphakia correction at the University Teaching Hospital of Yaounde. In this retrospective, non-comparative, consecutive case series study, we reviewed the records of patients who underwent an operation for aphakia correction by the means of injection of an angular supported foldable lens between January 2009 and December 2011 in the University Teaching Hospital Yaounde. Student's paired t-test was carried out to compare preoperative and postoperative visual acuity (VA) and intraocular pressure (TOP). P-values less than 0.05 were considered statistically significant. Twenty-one patients were included in the study; twelve were male (57.1%) and nine were female (42.9%). The mean age was 55.38 ± 17.67 years (range 9–75 years). The mean follow-up duration was 5.95 ± 3.14 months (range 2–12 months). The mean logMAR visual acuity was 1.26 ± 0.46 pre-operatively and 0.78 ± 0.57 post-operatively ( P = 0.003). The change in intraocular pressure was not statistically significant. Complications included intraocular hypertension (over 21 mmHg) in 3 patients (14.3%) and macular edema, pupillar ovalization, and retinal detachment in one patient each. The results indicate that injection of an angular support foldable lens in the anterior chamber is a useful technique for the correction of aphakia in eyes without capsular support. More extended follow-up, however, and a larger series of patients are needed to ascertain the effectiveness and safety of this procedure.

Purpose The purpose of this study was to evaluate the effect of correction of abnormal radiographic parameters on postoperative pain in a group of patients treated arthroscopically for femoracetabular impingement (FAI). Methods A retrospective study was performed on 23 patients affected by mixed-type FAI and treated arthroscopically. There were 11 males and 12 females with a mean age of 46.5 (range: 28–67) years. Center-edge (CE) and α angles were measured on preoperative and postoperative radiographic and magnetic resonance imaging (MRI) studies and were correlated with persistent pain at follow-up. Results The mean preoperative CE and α angles were 38.6 ± 5.2 and 67.3 ± 7.2 degrees, respectively. At follow-up, in the 17 pain-free patients, the mean pre- and postoperative CE angle were 38.1 ± 5.6 and 32.6 ± 4.8 degrees, respectively, whereas the mean pre- and postoperative α angles at MRI were 66.3 ± 7.9 and 47.9 ± 8.9 degrees, respectively. In six patients with persistent hip pain, the mean pre- and postoperative CE angles were 39.8 ± 3.6 and 35.8 ± 3.1 degrees, respectively, whereas the mean pre- and postoperative α angles were 70.0 ± 3.9 and 58.8 ± 2.6 degrees, respectively. Mean values of all the analyzed radiological parameters, except CE angle in patients with pain, improved significantly after surgery. On comparing patient groups, significantly lower postoperative α angles and lower CE angle were observed in patients without pain. Conclusion In case of persistent pain after arthroscopic treatment of FAI, a new set of imaging studies must be performed because pain may be related to an insufficient correction of preoperative radiographic abnormalities. Level of Evidence Level IV, retrospective case series.

Abstract Background Surgical epicardial AF ablation can be performed as a stand-alone (thoracoscopic) procedure or concomitant to other cardiac surgery. In hybrid AF ablation thoracoscopic surgical epicardial ablation is combined with a percutaneous endocardial ablation. The Medtronic Gemini-S clamp is a surgical tool that uses irrigated bipolar biparietal RF energy applied with two clamp lesions that overlap to create one epicardial box lesion including the posterior LA wall and the pulmonary veins. Case summary We describe three patients with therapy-refractory persistent AF and different stages of atrial remodelling in whom the Medtronic Cardioblate Gemini-S Irrigated RF Surgical Ablation System was used for hybrid AF ablation. Acute endocardial validation at the end of the hybrid ablation revealed a complete box lesion in all three cases. At 2-year follow-up, two out of three patients had recurrence of atrial arrhythmias. Invasive electro-anatomical mapping confirmed persistence of the box lesion, and the mechanism of arrhythmia recurrence in both patients was unrelated to posterior left atrium or the pulmonary veins. The third patient has been without arrhythmia symptoms since the ablation procedure. A 3D late gadolinium enhancement (LGE) magnetic resonance imaging (MRI) illustrates the ablation scar non-invasively in two cases. Discussion Thoracoscopic biparietal RF AF ablation with the Medtronic Cardioblate Gemini-S Irrigated RF Surgical Ablation System results in permanent transmural scar formation, irrespective of the stage of atrial remodelling, as shown in this small population by means of multimodality scar evaluation.

Femoral fractures increase the length of hospital stay for our patients for several reasons such as lack of blood, economic resources, and lack of infrastructure. The use of a C-arm has been shown to reduce patient morbidity due to early functional recovery and reduced hospital stay. Objective: To develop an intramedullary nailing technique without c-arm with a closed focus to reduce the duration of hospitalization of its patients as well as the cost related to the equipment used for follow-up. Methodology: prospective study on 35 patients for 1 year August 2020 to August 2021 Results: We followed 35 patients in which the mean age was 37.83 years with extremes of 18 and 78 years. The male sex predominates 21 against 14 women or 60% against 40% respectively. The sex ratio is 1.5. A total of 19 diaphyseal fractures (54.3%) were nailed, 9 supracondylar (25.7%) and 7 subtrochanteric (20%). Twenty-seven were closed fractures (71.1%), and 8 were open fractures (22.9%). The length of hospitalization was less than 3 days for 30 patients (85.7%), and more than 3 days for 5 patients (14.3%). Conclusion: We recommend that we promote this closed-hearth technique because it improves the postoperative follow-up of patients. Additionally, it would reduce exposure to radiation from c-arm in hospitals that have this equipment.

Introduction: To report the spectrum and frequency of conjunctiva tumours in an ocular oncology unit analysing the clinical profile of benign, precancerous and malignant conjunctival lesions. Methods: A retrospective case series of 462 consecutive patients diagnosed at the Ocular Oncology Unit of the University Hospital of Valladolid from 1992 to 2017. Results: Among 462 consecutive patients, the tumour was classified as melanocytic in 252 (54.5%) and non-melanocytic in 210 (45.5). Two hundred forty-eight males (mean age 51.63 (SD = 23.20)) and 214 females (mean age 48.27 (SD = 21.77)) were included. Mean patient age at diagnosis was 50.07 years (range = 1-92 years). The majority of tumours were benign (n = 307 (66.5%)) followed by precancerous (n = 103 (22.3%)) and finally by malignant ones (n = 52 (11.3%)). Benign lesions were predominantly found in younger individuals rather than premalignant (p < 0.05) and malignant ones (p < 0.05). Most of the melanocytic lesions were benign (88.5%), most epithelial ones were precancerous (61.4%) and most lymphoid lesions were malignant (56.3%). Tumours involving one or four quadrants of the ocular surface usually were benign, unlike tumours involving three quadrants that were malignant (16 (48.5%) p < 0.05). The majority of benign lesions were detected on females (n = 163 (53.1%)) by routine examination (n = 178 (86.4%)). However, main complaint in malignant tumours was the growth of the lesion (n = 39 (76.5%)). Conclusion: Most of the conjunctival tumours were melanocytic, mostly benign, closely followed by those of epithelial origin, with a predominance of precancerous lesions. Melanocytic, epithelial and lymphoid tumours accounted for over 90% of cases. A trend was identified with benign lesions being found in younger female patients on routine examination.

Abstract Purpose It is assumed that primary hyperparathyroidism (pHPT) in Multiple Endocrine Neoplasia (MEN) and lithium-associated pHPT (LIHPT) are associated with multiple gland disease (MGD), persistence and recurrence. The studies purpose was to determine frequencies, clinical presentation and outcome of sporadic pHPT (spHPT), LIHPT and pHPT in MEN. Additional main outcome measures were the rates of MGD and persistence/recurrence. Methods Retrospective analysis of medical records of 682 patients with pHPT who had attended the University Hospital of Marburg between 01–01–2004 and 30–06–2013. All patients were sent a questionnaire asking about their history of lithium medication. Results Out of 682 patients, 557 underwent primary surgery (532 spHPT, 5 LIHPT, 20 MEN), 38 redo-surgery (31 spHPT, 7 MEN), 55 were in follow-up due to previous surgery (16 spHPT, 1 LIHPT, 38 MEN) and 37 were not operated (33 spHPT, 1 LIHPT, 3 MEN). Primary surgeries were successful in 97.4%, revealed singular adenomas in 92.4%, double adenomas in 2.9% and MGD in 3.4% of the cases. Rates of MGD in MEN1 (82.35%) were significantly higher than in spHPT (3.8%), while there was no significant difference between LIHPT (20%) and spHPT. Rates of persistence/recurrence did not significantly differ due to type of surgery (bilateral/unilateral) or type of HPT (spHPT/LIHPT/MEN). Conclusions History of lithium medication is rare among pHPT patients. While MGD is common in MEN1, rates of MGD, persistence or recurrence in LIHPT were not significantly higher than in spHPT.
