Abstract BACKGROUND: Aneurysms of the internal carotid artery (ICA) bifurcation are rare, and no studies have compared patient outcomes after endovascular vs surgical treatment. OBJECTIVE: To report the safety, efficacy, and follow-up outcome of these 2 treatment options for patients with ICA bifurcation aneurysms. METHODS: Patient and aneurysm characteristics, treatment results, and follow-up outcomes (at 30 months) were analyzed from patient records and review of imaging findings. RESULTS: A total of 58 patients with ICA bifurcation aneurysms were treated. By interdisciplinary consensus, 30 aneurysms were assigned for coiling and 28 for clipping. Patients who underwent surgical clipping were younger and had larger aneurysms. More patients were assigned to coiling if their aneurysms originated only from the ICA bifurcation or projected superiorly. For the combined angiographic endpoint, complete and nearly complete occlusion (Raymond-Roy I + II), similar rates of 96% (coiling) or 100% (clipping) could be achieved. Raymond-Roy I occlusion occurred more often after clipping (79% vs 41% coiling). Follow-up of the endovascular group showed minor recanalization of the aneurysm neck (Raymond-Roy II) in 42%. One patient (4%) showed a major recanalization (Raymond-Roy III) and needed re-treatment. For incidental findings, no bleeding complications or new persistent neurological deficits occurred during follow-up. CONCLUSION: Treatment of ICA bifurcation aneurysms after interdisciplinary assignment to clipping or coiling is effective and safe. Despite significantly more minor recanalizations after coiling, the re-treatment rate was very low, and no bleeding was observed during follow-up. Multivariate analysis revealed that origin only from the ICA bifurcation was an independent predictor of aneurysm recanalization after endovascular treatment.

Midcarpal instability is a collective term for a number of conditions where the instability of the wrist is predominantly between the proximal and distal carpal rows. It has been regarded as relatively rare and infrequently requires surgical treatment. Palmar midcarpal instability is the most commonly found type of midcarpal instability and can be responsible for causing a clunking and painful wrist. The diagnosis is made on clinical grounds using the midcarpal instability provocative tests. Standard imaging and arthroscopic inspection do not usually confirm a definite diagnosis, but are important in excluding other pathologies. The classification and staging has been described using the extent of palmar translocation of the distal carpal row, which is elicited on passive stress tests. As this is a functional instability, it may be that a functional staging description might be better, and a proposed scheme is described. Treatment options including partial wrist fusions, tenodesis stabilizations and arthroscopic capsular shrinkage have been described in small case series with limited follow-up. There are no comparative series or randomized studies because of the relative rarity of this condition.

Abstract Microsurgical clipping of large paraclinoid aneurysms is challenging because of the complex anatomy of the dural rings, lack of easy proximal control, and wide aneurysm necks. Proximal retrograde suction decompression, or the Dallas technique, can reduce aneurysm turgor and, with aspiration of the trapped cervical and supraclinoid internal carotid arteries (ICAs), can collapse the aneurysm to aid microsurgical clipping.1-5  A woman in her late 30s presented with decreased right-eye visual acuity. Informed written consent was obtained for microsurgical management and publication. Upon cervical exposure of the carotid bifurcation, we performed a standard pterional craniotomy, trans-sylvian exposure, and intradural anterior clinoidectomy. After burst suppression and cross-clamping of the carotid, we inserted an angiocatheter at the common carotid artery (CCA). Distal temporary clips were placed on the posterior communicating artery and C7 ICA. With the cervical ICA unclamped, retrograde suction was continuously applied to deflate the aneurysm. We applied 2 pairs of fenestrated-booster clips to the aneurysm dome and a fifth clip to the aneurysm neck. After restoration of flow, indocyanine green angiography and Doppler assessments were performed. The proximal clip was converted into a curved clip to optimize ICA flow.  Postoperative angiography confirmed complete occlusion of the aneurysm. The patient was discharged on postoperative day 3, with stable visual acuity.6 This video demonstrates that retrograde suction decompression via the cervical CCA can be safely performed to facilitate clipping of complex paraclinoid ICA aneurysms. Comprehensive planning of temporary aneurysm trapping for suction decompression and permanent clip construct for aneurysm occlusion are needed for effective aneurysm repair.

Alveolar echinococcosis (AE) is an infectious zoonotic disease that is caused by Echinococcus multilocularis. The disease is generally identified accidentally because of the long asymptomatic period, has a malignant behaviour, and mainly occurs in the liver. Usually it is diagnosed in adults and is very rare in pediatric patients. We report two cases of AE and 1 differential case between AE and cystic echinococcosis (CE) in children: two of them had lesions in the liver and one had rare extrahepatic presentation of a cyst in the spleen. All our patients received chemotherapy with albendazole because surgical treatment was not recommended. The children were followed-up from 10 to 30 months and no significant improvement was seen. In this report we discuss the difficulties we faced in the treatment and follow-up of these patients. We also review the main clinical manifestations, general diagnostic methods, and treatment options of AE according to the current literature.

Background: Symptomatic genu recurvatum is a challenging condition to treat. Both osseous and soft tissue treatment options have been reported to address symptomatic genu recurvatum. Purpose/Hypothesis: The purpose of this article was to review the current literature on surgical treatment options for symptomatic genu recurvatum and to describe the associated clinical outcomes. We hypothesized that anterior opening-wedge proximal tibial osteotomy (PTO) would be the most common surgical technique described in the literature and that this intervention would allow for successful long-term management of symptomatic genu recurvatum. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review was performed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, with the inclusion criterion of surgical treatment options for symptomatic genu recurvatum. Recurvatum secondary to polio, cerebrovascular accident, or cerebral palsy was excluded from this review. Results: A total of 311 studies were identified, of which 6 studies with a total of 80 patients met the inclusion criteria. Causes of genu recurvatum included physeal arrest; soft tissue laxity; and complications related to fractures, such as prolonged immobilization and malalignment. Mean follow-up times ranged from 1 to 14.5 years postoperatively. There were 5 studies that described anterior opening-wedge PTO, 2 of which used the Ilizarov distraction technique. All 3 studies that used PTO without the Ilizarov technique reported correction of recurvatum and increased posterior tibial slope; 2 of these studies also included subjective outcomes scores, reporting good or excellent outcomes in 70% (21/30) of patients. Of the studies that used the Ilizarov technique, both reported correction of recurvatum and increased posterior slope from preoperative to postoperative assessments. Both of these studies reported good or excellent subjective outcomes postoperatively in 89.5% (17/19) of patients. Additionally, 1 study successfully corrected recurvatum by performing a retensioning of the posterior capsule to address knee hyperextension, although follow-up was limited to 1 year postoperatively. Conclusion: Anterior opening-wedge PTO, with or without postoperative external fixation with progressive distraction, was found to be a reliable surgical treatment for symptomatic genu recurvatum. After surgical management with PTO, patients can expect to achieve correction of knee hyperextension, restoration of a more posterior tibial slope, and increased subjective outcome scores.

Background: Endovascular treatment options for internal carotid artery (ICA) dissection with tandem intracranial occlusion are evolving. We report 2 cases of stent reconstruction of carotid loop dissections. Methods: Two patients with symptomatic ICA dissections of true 360° tonsillar loops and tandem intracranial occlusions were treated with manual aspiration thrombectomy (MAT) and telescoping Zilver self-expanding peripheral stents. Patient demographics, clinical presentations, endovascular techniques, and clinical outcomes were reviewed. Results: In both cases, MAT achieved modified Treatment in Cerebral Ischemia scale 2B reperfusion, and complete endovascular reconstruction of the dissected extracranial loop was performed. Both patients had improved pre- to postintervention National Institutes of Health Stroke Scale scores (16 to 0 and 14 to 0), and both had modified Rankin scale scores of 1 at 3-month follow-up. Conclusions: Stent reconstruction of complex cerebrovascular anatomy is increasingly feasible with advancements in stent technology and catheter support system design. This technique may be of use to neuroendovascular surgeons who encounter variant ICA anatomy.

ABSTRACT A pseudoaneurysm of the inferior gluteal artery presenting as sciatic nerve compression is reported in a 40-year-old woman. Following a transvaginal needle biopsy for endometriosis, the patient developed left sciatic pain and a nonpulsatile mass palpable in the left buttock thought to represent a pyriformis hematoma. Sequential computed tomographic scans were consistent with this diagnosis. Persistent pain and progression of neurological deficits led to surgical exploration. Posterior exposure of the pyriformis muscle and proximal sciatic nerve revealed a large pseudoaneurysm of the inferior gluteal artery compressing the nerve. A laparotomy was performed and the internal iliac artery was ligated, followed by evacuation of the aneurysm contents and repair of the aneurysm neck via a posterior approach. The patient has remained pain-free with progressive improvement in neurological function after 1 year follow-up. Aneurysms of the gluteal artery are unusual, predominantly occur after significant pelvic trauma, and rarely present as sciatica. Pertinent aspects of the patient history and clinical findings are atypical for discogenic sciatica. Because of the rarity of this entity, preoperative diagnosis is usually not achieved. Angiography or magnetic resonance imaging should be performed in patients with atypical sciatica and a mass in the region of the proximal sciatic nerve, particularly after trauma.

Cervical Fractures

The clinicopathological features of cervical fractures in 56 dogs were reviewed. "Hit by car" (HBC) was the most common inciting cause, and the axis and atlas were the vertebrae most frequently affected. Surgical treatment was associated with high (36%) perioperative mortality. However, all dogs that survived the perioperative period achieved functional recovery. Functional recovery was achieved in 25 (89%) of 28 nonsurgically treated dogs with adequate follow-up. Overall, severity of neurological deficits (nonambulatory status) and prolonged interval (five days or longer) from trauma to referral were associated with poorer outcome. Nonsurgical treatment is a viable therapeutic approach for many dogs with cervical fractures. Early neck immobilization and prompt referral are recommended, because delay in referral decreases the likelihood of functional recovery.

Abstract BACKGROUND: Unruptured aneurysms of the cavernous and paraclinoid internal carotid artery can be approached via microsurgical and endovascular approaches. Trends in treatment reflect a steady shift toward endovascular techniques. OBJECTIVE: To analyze our results with multimodal treatment. METHODS: We reviewed patients with unruptured cavernous and paraclinoid internal carotid artery aneurysms proximal to the posterior communicating artery treated at a single center from 2007 to 2012. Treatment included 4 groups: (1) stent-assisted coiling, (2) pipeline endovascular device (PED) flow diverter, (3) clipping, and (4) trapping/bypass. Follow-up was 2 to 60 months. RESULTS: The 109 aneurysms in 102 patients were studied with the following treatment groupings: 41 were done with stent-assisted coiling, 24 with Pipeline endovascular device, 24 by microsurgical clipping, and 20 by trap/bypass. Group: (1) two percent had delayed significant intraparenchymal hemorrhage; (2) thirteen percent had central nerve palsies, 8% had small asymptomatic infarcts, and 4% had small, asymptomatic remote-site hemorrhages; (3) twenty-nine percent of patients suffered from transient central nerve palsies, 4% experienced major stroke, and 8% had small intracerebral hemorrhages; (4) thirty-five percent had transient central nerve palsies, 10% had strokes, and 10% had intracerebral hemorrhages. In terms of follow-up obliteration, 83% had complete/nearly complete obliteration at last follow-up, 17% had residual aneurysms, and 10% required retreatment. Ninety-six percent of group 1 (35/38), 100% of group 2 (23/23), 100% of group 3 (21/21), and 95% of group 4 had modified Rankin Scale scores of 0 to 1. CONCLUSION: Treatment of these aneurysms can be carried out with acceptable rates of morbidity. Careful patient selection is crucial for optimal outcome. Endovascular treatment volumes likely will continue to predominate over microsurgical techniques as changing skill sets evolve in neurosurgery, but individualized application of all available treatment options will continue.

Artery Pseudoaneurysm

Abstract Pseudoaneurysms of the cervical internal carotid artery may generate grave risk from catastrophic rupture, thromboembolic stroke, or mass effect. They have many causes, including malignancy, infection, and iatrogenic and most commonly blunt or penetrating trauma.1 These aneurysms require treatment to eliminate their risk. Treatment options include trapping, with or without revascularization, or endovascular stenting. Trapping without revascularization requires evaluation of the cerebral collateral under a physiological challenge, which is usually done with a balloon occlusion test, which is not applicable in this lesion.2 Occluding the carotid without revascularization carries the risk of delayed ischemia and aneurysm formation.3,4 Carotid stenting has been applied in the treatment of these lesions5,6; however, the extent of the lesion in our patient from the carotid bifurcation to the petrous carotid makes endovascular treatment challenging. We present a patient with a delayed post-traumatic pseudoaneurysm of the carotid artery that extended from the bifurcation to the petrous carotid who was treated with trapping and high-flow saphenous vein bypass from the proximal cervical internal carotid to the petrous carotid. Adequate exposure of the petrous carotid to perform anastomosis requires a thorough knowledge of the anatomy and surgical nuances, which we demonstrate here through a zygomatic approach.7 The patient consented to the procedure and publication of imaging.
