RESUMO
Lumbar synovial cysts (LSC) that protrude into the spinal canal can cause lower back pain, neurogenic claudication, and radiculopathy. Often diagnosed in the elderly population (typically â¼60 years of age) with a slight preponderance for females, their underlying etiology is thought to be due to degeneration of the adjacent facet joint, with the most common location at the level of L4-L5. Treatment of LSC can be conservative (with NSAIDs and physical therapy), percutaneous (with rupture), or surgically (with decompression with or without fusion). Percutaneous treatment of LSC involves rupturing the cyst by injecting it with steroids and local anesthetics. Although this option is less invasive than surgery, multiple studies have documented recurrence with this method and patients eventually undergoing surgical intervention. In this report, we document a case where a patient who presented with a symptomatic LSC underwent successful percutaneous treatment with bleomycin.
RESUMO
OBJECTIVE: Unruptured, wide-necked middle cerebral artery (WN-MCA) aneurysms have traditionally been considered ideal candidates for microsurgery (MS), although endovascular treatment (EVT) has dramatically increased in popularity with the advent of novel devices such as intrasaccular flow disruptors. The purpose of this study was to evaluate the safety and efficacy of MS versus EVT for unruptured WN-MCA aneurysms. METHODS: The NeuroVascular Quality Initiative Quality Outcomes Database (NVQI-QOD) Cerebral Aneurysm Registry, a multiinstitutional, prospectively collected procedural database, was queried for cases of unruptured WN-MCA aneurysms treated with MS or EVT between 2015 and 2022. A wide neck was defined as an aneurysm neck ≥ 4 mm or a dome/neck ratio ≤ 2. Demographics and aneurysm characteristics were queried. Propensity score matching (PSM) was utilized to match aneurysm size, number of aneurysms treated, patient age, and aneurysm status. Safety outcomes were evaluated including intraoperative and postoperative complication rates. Aneurysm occlusion status and clinical outcomes using the modified Rankin Scale (mRS) score at discharge and the last follow-up were also assessed. RESULTS: Of 671 unruptured MCA aneurysms, 319 were wide necked. Thirty cases were excluded, as the aneurysm had been previously treated. Two hundred eighty-nine operations (203 EVT, 86 MS) in 282 patients satisfied inclusion criteria. After PSM, there were 86 operations in each group for analysis. The mean aneurysm width was 5.0 (EVT) versus 4.9 mm (MS; p = 0.285). Safety data showed similar intraoperative (7.0% EVT vs 3.5% MS, p = 0.496) and postoperative (4.7% vs 7%, p = 0.746) complication rates. The MS patients were more likely to have complete aneurysm occlusion at discharge (90.4% vs 58.8%, p < 0.001). In a limited subset of patients (52.9%) for whom outcome data were available, the EVT patients were more likely to have an mRS score 0 at discharge (50/59 [84.7%] vs 29/54 [53.7%], p < 0.0003] and at the last follow-up (36/55 [65.5%] vs 13/36 [36.1%], p = 0.006). CONCLUSIONS: This study describes a large, modern cohort of propensity score-matched patients who underwent treatment of unruptured WN-MCA aneurysms. Safety data on intraoperative and postoperative complication rates were similar in both treatment groups. MS was more likely to result in complete aneurysm occlusion at discharge. In a subset of patients with available outcome data, EVT was associated with better functional outcomes at discharge and the last follow-up. Given the lack of complete follow-up data and rates of retreatment, these results should be interpreted cautiously.

Selective ophthalmic artery infusion of chemotherapy (SOAIC) has emerged as the standard of care for retinoblastoma (RB). Intranasal oxymetazoline (INO), Afrin, is often intraoperatively administered adjunctively to optimize flow to the orbit. There has been one report to date that suggests the adjunctive use of INO has led to systemic side effects. To our knowledge, this is the first documented case of INO causing urinary retention in a patient undergoing SOAIC, and the recommended treatment.

BACKGROUND: Endovascular treatment of large complex morphology aneurysms is challenging. High recanalization rates have been reported with techniques such as stent-assisted coiling and balloon-assisted coiling. Flow diverter devices have been introduced to improve efficacy outcomes and recanalization rates. Thromboembolic complications and in-device stenosis are certainly more worrisome when treatment of bilateral internal carotid arteries has been performed. This study aimed to report our experience with mid-term imaging follow-up of staged bilateral Pipeline embolization device placement for the treatment of bilateral internal carotid artery aneurysms. METHODS: We reviewed the clinical, angiographic, and follow-up imaging data in all consecutive patients treated with bilateral internal carotid artery aneurysms who underwent elective Pipeline embolization. RESULTS: Six female patients were treated, harboring a total of 13 aneurysms. Of these, 60% were asymptomatic. Diplopia and headache were the most common symptoms. The most common location was the paraclinoid segment (6/13), including by cavernous segment (4/13) and ophthalmic segment (2/13). Successful delivery of the device was achieved in 12 cases. Difficult distal access precluded the deployment of the device in one case. The treatment was always staged with at least eight weeks' difference between the two procedures. All aneurysm necks were covered completely. There were no periprocedural complications. Angiographic follow-up ranged between 3 and 12 months, and computed tomography angiogram follow-up ranged between 2 and 24 months. Complete aneurysm occlusion was achieved in all cases. CONCLUSION: In our series, Pipeline deployment for the treatment of bilateral internal carotid artery aneurysms in a staged fashion is safe and feasible. Mid-term imaging follow-up showed permanent occlusion of all the treated aneurysms.

This retrospective study evaluated the safety and feasibility of a new arterial femoral access closure device in neurointerventional procedures. The study includes all consecutive adult patients who underwent femoral arteriotomy closure with the MynxGrip™ closure device after Neurointerventional procedures performed between June and December 2012. All patients had a follow-up color Doppler ultrasound (US) within 48 hours after the procedure, which was independently interpreted by two experienced radiologists to evaluate for access site complications. Device success/failure, sheath size, ambulation time, and periprocedural complications were recorded. Fifty-five closure devices were deployed in 53 patients. There were 23 (43%) males and 30 (57%) females; age ranged from 22 to 84 years (mean: 52.1 years). Thirty of the 55 procedures (55%) were therapeutic and 25 were diagnostic interventions (45%). Sheath sizes used were 5F in 35 procedures (64 %) and 6F in 20 procedures (36%). The right femoral artery was accessed in 51 procedures (93 %) and the left in four procedures (7%). There was only one (1.8 %) minor periprocedural complication (small hematoma). Hemostasis was successful in 51 of the 55 procedures (93 %) with subsequent early ambulation. No device-induced complications associated with serious clinical sequelae were reported. In our small series, the MynxGrip™ femoral access closure device provided a safe and feasible way of closing the femoral artery puncture site after neurointerventional procedures with low minor complication rates and no major complications. Further large prospective randomized trials are necessary to evaluate the efficacy of the device.

It is difficult to identify normal peritoneal folds and ligaments at imaging. However, infectious, inflammatory, neoplastic, and traumatic processes frequently involve the peritoneal cavity and its reflections; thus, it is important to identify the affected peritoneal ligaments and spaces. Knowledge of these structures is important for accurate reporting and helps elucidate the sites of involvement to the surgeon. The potential peritoneal spaces; the peritoneal reflections that form the peritoneal ligaments, mesenteries, and omenta; and the natural flow of peritoneal fluid determine the route of spread of intraperitoneal fluid and disease processes within the abdominal cavity. The peritoneal ligaments, mesenteries, and omenta also serve as boundaries for disease processes and as conduits for the spread of disease.
