Pseudoaneurysms of the neck are seldom, and those caused by neck infections especially parapharyngeal abscess are even rarer. However, it is life-threatening and may bring sudden death due to the obstruction of airway and the pseudoaneurysms rupture. We analyzed the clinical features, diagnosis and treatment of the disease through a case summary and literature review in order to guide clinical diagnosis and treatment of pseudoaneurysms. The patient, whom we presented was an 87-year-old male and admitted in emergency of our hospital with the chief complaint of neck swelling for 7 days and shortness of breath for 2 days. Cervical ultrasound examination showed that there was an liquid dark area next to the left common carotid artery which was approximately 8.0 cm × 5.0 cm, consideration of formation of left carotid artery pseudoaneurysm, and the liquid dark area which was visible on the right considered of pseudoaneurysm or infection. Angiography of neck showed a clustered high-density shadow around the bifurcation of the left carotid artery, with an overall range of approximately 65 mm × 52 mm × 72 mm, the pseudoaneurysms for sure, while on the right side of the lesion, mixed low density shadows with air could be seen, the parapharyngeal abscess for sure.Then he was diagnosed as the pseudoaneurysm of left internal carotid artery which was caused by parapharyngeal abscess. After tracheal intubation and anti-infection treatment, the patient died due to hemorrhagic shock of the ruptured of the pseudoaneurysm. Morever we performed literature search on PubMed, Wanfang database and CNKI with keywords of "neck pseudoaneurysm, neck infection, parapharyngeal abscess" and enrolled 10 cases. Then we summarized the clinical characteristics and treatment. We analyzed and summarized the 10 case reports, in which the number of male was 7. Among them, there were 4 pediatric, and 6 adults were enrolled overall. Most of the symptoms were neck swelling, and the diseased blood vessel was mainly the right internal carotid artery which accounted for half overall. All the patients underwent surgical intervention, and recovered well. So we draw the conclusion that the clinical incidence of cervical pseudoaneurysms is low and can be caused by a variety of factors, especially caused by infectious factors. When a patient has a progressive pulsating mass in the neck, the preliminary diagnosis should be made by ultrasound as soon as possible, and the aortic enhancement CT should be used to further confirm.For a patient with cervical pseudo-aneurysms caused by parapharyngeal infections, he should take operation timely combined with antibiotic treatment in time.

Objective: To evaluate the efficiency of internal carotid artery (ICA) embolization technology in endoscopic salvage surgery for recurrent nasopharyngeal carcinoma (rNPC) invading the ICA. Methods: From January 2016 to March 2021, 83 patients with rNPC who invaded the ICA and underwent endoscopic extended nasopharyngectomy were retrospectively collected from the Eye & ENT Hospital in Fudan University, including 60 males and 23 females. The age of the patients ranged from 27 to 77 years. The standard of ICA invasion was that the distance from the lesion to the ICA on enhanced MRI was ≤ 1.8 mm. The clinical characteristics, ICA management strategy and survival prognosis of patients were analyzed, and the effectiveness of ICA embolization was evaluated. Kaplan-Meier method was used to calculate the survival rate and Log-rank test was used to compare the difference. Results: In 83 patients with rNPC, there were 13 patients with rT2, 38 patients with rT3, 32 patients with rT4, and 16 patients had lymph node metastasis. A total of 37 patients (44.6%) underwent ICA coil embolization before surgery, of which 2 cases underwent external carotid-middle cerebral artery artery bypass grafting and ICA embolization due to positive balloon occlusion test (BOT). Patients with positive surgical margin accounted for 24.1% (20/83). Among them, patients with rT4 and patients without ICA embolization had a higher positive rate of surgical margin (P value was 0.001, 0.043, respectively). The 3-year overall survival (OS) and progression free survival (PFS) rate of all patients was 46.5% and 26.7%, respectively. In addition, the 3-year OS and PFS of patients with ICA embolization was significantly higher than those without ICA embolization, respectively (69.1% vs 27.8%, P=0.003; 33.9% vs 18.9%, P=0.018). Only 2 patients (2/37, 5.4%) had cerebral infarction complications after coil embolization of the affected ICA due to negative BOT. Conclusion: Preoperative ICA embolization can be used to treat patients with rNPC invading the ICA, improve the total removal rate and survival rate of patients, which is an effective salvage treatment.

Objective: By summarizing the technical points and therapeutic outcomes of combing infratemporal fossa approach (IFA) and internal carotid artery (ICA) reconstruction for the colossal skull base tumor invading ICA in petrous bone, the clinical application value was discussed. Methods: Five patients (2 males, 3 females,aging from 27 to 55 years old) who received surgeries between July 2015 and May 2017 for lateral skull base pathology involved petrous ICA using technique combined IFA and pre-reconstruction, were reviewed. Results: Among the five patients, three were paraganglioma of head and neck, one was carotid aneurysms, and one was recurrent adenoid cystic carcinoma (ACC). The median tumor size in the largest cross-section was 60 mm × 51 mm (range, 28 mm × 22 mm-72 mm × 58 mm). Complete excision was achieved with IFA and ICA reconstruction. The median blood loss volume was 1 000 ml (range, 600-2 500 ml). Four cases showed no new long-term neurologic sequelae, while one showed hemiplegia due to graft vessel occlusion. Except for the one with ACC having facial nerve cut, others achieved good facial nerve function of HB grade Ⅰ to Ⅱ during 3 to 12 months, follow-up. No tumor recurrence was observed over the median duration of follow-up for above 36 months (range, 36-58 months). Conclusion: For lesions involved superior part of ICA, which is unable to separate from ICA, IFA and ICA reconstruction can achieve complete excision.

Restoration of cerebral blood flow is particularly important for the treatment of ischemic cerebrovascular disease. It is notable that surgical approaches play a unique role in treating this devastating disease. Among them, mechanical thrombectomy facilitates rapid and effective recanalization of occluded intracranial large vessels causing ischemic stroke, which contributes to improvement of cerebral perfusion in the ischemic penumbra; decompressive craniectomy is an important therapeutic option for acute massive cerebral infarction, and the timing of surgery determines the final clinical outcomes; for carotid endarterectomy in carotid-artery stenosis, individualized surgical plan is important for the safety and effectiveness of the operation; in the surgical revascularization of Moyamoya disease, precise evaluation of clinical and radiological characteristics, optimal surgical strategies and accuracy of intraoperative judgment will yield maximal therapeutic effects; and hybrid surgery is feasible for the therapy of complex ischemic cerebrovascular diseases, such as extracranial/intracranial arteries tandem stenosis and symptomatic chronic total occlusion of carotid artery. This paper reviews recent technical and clinical advances in the surgical treatment of ischemic cerebrovascular disease.

OBJECTIVETo investigate the causes and strategy of difficult intraarterial mechanical thrombectomy (≥3 times) in patients with acute ischemic stroke (AIS).

METHODSThe clinical data of 8 cases of AIS with thrombectomy ≥3 times admitted in Department of Neurology, the 306(th) Hospital of People's Liberation Army from June to October in 2015 was analyzed retrospectively. There were 7 male and 1 female patients, aged from 38 to 86 years with an average age of (70±15) years, in which 5 cases were cardiogenic cerebral embolism and 3 cases were large artery atherosclerotic infarction. The National Institute of Health stroke scale (NIHSS) score (M (QR)) was 16 (12) before procedure and modified thrombolysis in cerebral infarction (mTICI)score were 0 in all the patients. Solitaire AB was used in thrombectomy in the occlusion of the arteries.

RESULTSThe causes of difficult intraarterial thrombectomy included multiple thrombus, tortuosity in vascular paths, guiding catheter being placed below the internal carotid artery siphon leading to weak strength of suction and support of stent, embolus dropping in the thrombectomy and inadequate anesthesia. After successful thrombectomy 3 cases had mTICI score of 2a, 4 cases of 2b, 1 case of 3. The NIHSS score was 5 (24) at 7(th) day after treatment. At the 90-day follow-up 5 patients had good prognosis (modified Rankin score 0 to 2) and 3 had disability (modified Rankin score 3 to 4).

CONCLUSIONCases of AIS with difficult intraarterial thrombectomy can be treated by improving thrombectomy materials and technique, reasonable anesthesia and perioperative medication in decision-making strategy.

To seek a reasonable microsurgical technique for dorsal wall aneurysms in the internal carotid artery (ICA), and to evaluate its efficacy.
 Methods: A total of 21 patients with dorsal wall aneurysms in the ICA who received microsurgical techniques were retrospectively analyzed. The directive surgical clapping was applied for saccular aneurysm, while the techniques of stitching and wrapping, simple wrapping, and trapping with extracranial-intracranial bypass were used for cystic and blood blister false aneurysms.
 Results: One patient died after operation, 1 patient suffered rebleeding and gave up treatment, the remaining 19 patients achieved saticfactory outcomes.
 Conclusion: According to types of aneurysm wall, the different microsurgical treatments should be applied, and good outcomes can be achieved for patients with dorsal wall aneurysms in the ICA.

OBJECTIVETo evaluate the short-term outcome of single stenting technique for unruptured, wide-necked, tiny aneurysms of the anterior circulation.

METHODSEleven unruptured, wide-necked, tiny aneurysms of the anterior circulation were treated by a single stent deployed in the parent artery between January 2008 and July 2013 in Department of Neurosurgery in Beijing Hospital. The maximum diameter of the aneurysms ranged from 2.0 to 3.0 mm, mean (2.4 ± 0.4) mm, and the dome-to-neck ratios were all ≤ 1.2. The locations were clinoid segment of internal carotid artery (n=2), posterior communicating artery origin (n=4), anterior choroidal artery origin (n=2) and middle cerebral artery bifurcation (n=3). All internal carotid aneurysms were located in the medial and/or ventral wall of the internal carotid artery. The rate of aneurysm obliteration and rupture during follow-up was obtained by repeat angiography and clinic or telephone interview respectively.

RESULTSSole stent placement in the parent artery was intentionally performed for nine aneurysms, while attempt of coiling after stent deployment for the other two aneurysms failed due to unsuccessful microcatherization. Ten stents were successfully deployed, of which one was used to treat two tandem lesions simultaneously. Only one aneurysm became smaller immediately postprocedure. No perioperative complications occurred. Angiographic follow-up after a mean period of (13 ± 6) months (range 8-24 months) revealed that 8 aneurysms did no change in size, 2 became smaller and only one was totally occluded. Asymptomatic in-stent stenosis of the parent artery was found in all 3 shrinking or occluded aneurysms. No aneurysm rupture was observed in the clinical follow-up.

CONCLUSIONFor those unruptured, wide-necked, tiny aneurysms arising at branching sites in the anterior circulation, single stenting technique seems to be a safe alternative treatment, while the short-term rate of aneurysm occlusion is low.

OBJECTIVETo investigate the techniques and effect of surgical resection of large intra- and extra-ventricular craniopharyngiomas via anterior interhemispheric trans-lamina terminalis approach.

METHODSFifty-two patients who were surgically treated for large intra- and extra-ventricular craniopharyngiomas were retrospectively analyzed. All patients underwent surgery via anterior interhemispheric trans-lamina terminalis approach. Of the 52 patients, 28 were male and 24 were female, with age ranging from 3 to 67 years (mean age 33.5 years). The maximum tumor diameter varied from 4.0 to 7.8 cm, with mean diameter of 5.1 cm. Contrast-enhanced MRI was underwent to determine the extent of tumor resection on the 1 to 3 months after surgery.

RESULTSTotal removal of the lesion was achieved in 47 cases (90.4%), 5 patients underwent subtotal resection (9.6%). Division of the anterior communicating artery was performed in 6 patients with no early or late complications related to division of the artery. Visual acuity was preserved or improved in 44 patients (84.6%). Preservation of the pituitary stalk were achieved in 33 patients (63.5%). No surgery-related deaths occurred. The postsurgical follow-up period varied from 3 months to 68 months (mean 25.4 months). Twenty-three cases had endocrinological deficit and received some form of hormonal replacement after surgery. Permanent diabetes insipidus occurred in 18 cases. Three patients died and 6 patients suffered recurrence during the followed-up period.

CONCLUSIONSThe anterior interhemispheric approach, with opening of the lamina terminalis, is a valid choice for large intra- and extra-ventricular craniopharyngiomas. These tumors can be removed without significant sequelae related to the surgical approach because optic nerves, optic chiasm, internal carotid artery, hypothalamic structures and pituitary stalk can be seen and effectively protected.
