    骨发育不良(OD)是一种良性纤维骨性病变,分类为根尖周,局灶性或花语,一些罕见病例被诊断为扩张性OD。
    一名43岁的女性表现为下颌骨严重扩张和牙齿移位。
    成像扫描显示前下颌骨有一个扩张性病变,随着中部区域不透明度的变化,以及#37和#47牙齿区域的其他较小病变,与扩张性OD一致。
    手术切除,然后使用微血管化腓骨移植立即重建下颌骨缺损。
    患者进行了4年的随访,具有足够的下颌骨连续性,咀嚼,吞咽,重新建立了说话能力。
    大手术切除后需要立即重建,因为组织会随着时间的推移而收缩,妨碍后期重建。微血管化腓骨移植旨在通过骨整合植入物实现充分的功能康复,并且需要长期随访,因为花语OD可能演变成扩张性OD。
    UNASSIGNED: Osseous dysplasia (OD) is a benign fibro-osseous lesion classified as periapical, focal or florid with some rare cases being diagnosed as expansive OD.
    UNASSIGNED: A 43-year-old female presented with gross mandible expansion and tooth displacement.
    UNASSIGNED: Imaging scans revealed an expansive lesion in the anterior mandible, with varying opacity in the central region, and other smaller lesions in the region of teeth #37 and #47, consistent with expansive OD.
    UNASSIGNED: Surgical resection followed by immediate reconstruction of the mandibular defect using a microvascularized fibular graft.
    UNASSIGNED: The patient had a 4-year follow-up, with adequate mandibular bone continuity, mastication, swallowing, and speaking ability reestablished.
    UNASSIGNED: Immediate reconstruction after large surgical resection is required as tissues retract over time, hampering late reconstructions. Microvascularized fibular graft aims at adequate and functional rehabilitation with osseointegrated implants and long-term follow-up is needed as florid OD may evolve into expansive OD.

    背景:复杂的脑血管搭桥手术可能会增加术中并发症的风险,如移植物血栓形成。需要新的技术来优化这些具有挑战性的案例的管理。
    方法:一名20多岁的妇女偶然被诊断患有1.5厘米的基底动脉尖动脉瘤,在2年的主动监测中增长到3.5厘米。然后建议进行明确的治疗,将血流逆转和基底干Hunterian结扎计划作为桡动脉移植物(RAG)旁路:M2(S-Ec)RAG(E-Sc*)P2。术中移植物血栓形成促使多次尝试抢救操作;但是,最终需要完整切除和重复吻合.该程序是使用一种新颖的双插入技术完成的,在远端吻合近端约1cm处结扎索引RAG(最终旁路:M2[S-Ec*]RAG[E-Ec*]RAG\'[E-Sc]P2)。这些技术修改为重复旁路和端对端吻合术而不是端对端吻合术提供了较少深度的受体部位。共同促进更有效和更容易的救助。病人手术后恢复良好,并且在动脉瘤内成功实现了血流逆转。
    结论:尽管复杂的脑血管搭桥手术术中血栓形成的风险增加,具有救助技术的设施可以带来技术和临床上优异的结果。我们报告了一种新型的第四代双插入旁路的成功使用,该旁路缩短了工作距离并使用了更有利的吻合技术。这种旁路可以促进需要完全修复颅内-颅内结构的患者的安全有效的显微外科手术。
    Complex cerebrovascular bypass operations may confer an increased risk of intraoperative complications, such as graft thrombosis. Novel techniques are needed to optimize the management of these challenging cases.
    A woman in her late 20s was incidentally diagnosed with a 1.5-cm basilar apex aneurysm, which grew to 3.5 cm over 2 years of active surveillance. Definitive treatment was then recommended with flow reversal and Hunterian ligation of the basilar trunk planned as a radial artery graft (RAG) bypass: M2 (S-Ec) RAG (E-Sc*) P2. Intraoperative graft thrombosis prompted multiple attempted salvage maneuvers; however, complete excision and repeat anastomosis were ultimately required. The procedure was completed using a novel double-interposition technique, with ligation of the index RAG approximately 1 cm proximal to the distal anastomosis (final bypass: M2 [S-Ec*] RAG [E-Ec*] RAG\' [E-Sc] P2). These technical modifications yielded a less deep recipient site for the repeat bypass and an end-to-end anastomosis rather than an end-to-side anastomosis, collectively facilitating a more efficient and facile salvage. The patient recovered well from surgery, and flow reversal was successfully achieved within the aneurysm.
    Despite the increased risk of intraoperative thrombosis with complex cerebrovascular bypass operations, facility with salvage techniques can lead to technically and clinically excellent outcomes. We report the successful use of a novel fourth-generation double-interposition bypass that shortens the working distance and uses a more favorable anastomosis technique. This bypass may facilitate safe and efficient microsurgery in patients who require complete revision of an intracranial-intracranial construct.

    背景:在儿科人群中从未描述过感染的pop动脉假性动脉瘤。医生需要意识到它的呈现和管理,为了充分诊断和治疗这种疾病。
    方法:我们描述了一个14岁男孩的案例,他在打篮球后出现了以po窝为中心的肌炎和蜂窝织炎。开始静脉内治疗头孢唑啉。5天后,他经历了膝盖疼痛发作,结果是一种伴pop动脉假性动脉瘤的pop化脓性肌炎。对pop动脉进行了隐静脉移植旁路,并切除了pop假性动脉瘤。连续静脉注射头孢唑林6周,预防性使用乙酰水杨酸6个月。
    结论:该病例强调,如果软组织感染患者在使用适当的抗生素几天后出现持续性疼痛,则重复进行放射学检查的重要性。pop假性动脉瘤可以通过超声成像诊断,并通过pop-pop旁路治疗。我们的病人需要在手术后6个月的静脉移植物处进行导管引导的吻合术扩张,然后发展良好,并在扩张后6个月回到打篮球。
    BACKGROUND: An infected popliteal pseudoaneurysm has never been described in the pediatric population. Physicians need to be aware of its presentation and management, in order to diagnose and treat this medical condition adequately.
    METHODS: We describe the case of a 14-year-old boy who developed myositis and cellulitis centered at the popliteal fossa after playing basketball. A treatment of intravenous cefazolin was started. 5 days later, he experienced a knee pain flare-up, which turned out to be a popliteal pyomyositis with a pseudoaneurysm of the popliteal artery. A saphenous vein graft bypass of the popliteal artery and an excision of the popliteal pseudoaneurysm were performed. Intravenous cefazolin was continued for 6 weeks and prophylactic acetylsalicylic acid for 6 months.
    CONCLUSIONS: This case highlighted the importance of repeating radiologic investigations if a patient suffering from soft tissue infection has persistent pain after several days of appropriate antibiotics. A popliteal pseudoaneurysm can be diagnosed with ultrasound imaging and treated with a popliteal-popliteal bypass. Our patient needed a catheter-guided dilation of the anastomosis at the vein graft 6 months post-surgery, and then evolved favorably and went back to playing basketball 6 months post-dilation.

    pop动脉卡压综合征(PAES)是一种罕见的血管疾病,在每个受影响的腿中,与不同症状相关的双侧PAES病例非常罕见。为了提高当前对这种情况的表现和治疗的理解,本文描述了一例双侧PAES,并对相关文献进行了相应的综述.回顾性评估了诊断和治疗一名双侧PAES患者的总体过程,以提供有关该疾病的全面见解。该患者是通过对比增强计算机断层扫描(CT)诊断的,右侧有症状的PAES通过自体大隐静脉移植动脉旁路手术成功治疗。相比之下,该患者的无症状左侧PAES接受密切随访监测.术后随访2年,该患者未出现任何症状或并发症.因此,自体大隐静脉移植动脉旁路手术是治疗PAES的一种安全有效的方法,而对于无症状的PAES病例,即使是双侧表现的患者,也可能不需要手术。
    Popliteal artery entrapment syndrome (PAES) is a rare vascular disease, and cases of bilateral PAES associated with distinct symptoms in each of the affected legs are very rare. In an effort to improve current understanding regarding the presentation and treatment of this condition, a case of bilateral PAES is herein described with a corresponding review of the associated literature. The overall process of diagnosing and treating one patient affected by bilateral PAES was retrospectively assessed to provide comprehensive insight regarding this disease. This patient was diagnosed via contrast-enhanced computed tomography (CT), and right-sided symptomatic PAES was successfully treated via autogenous saphenous venous graft arterial bypass surgery. In contrast, the asymptomatic left-sided PAES in this patient was subject to close follow-up monitoring. Over a 2-year postoperative follow-up period, this patient did not experience any symptoms or complications. As such, autogenous saphenous venous graft arterial bypass surgery represents a safe and efficacious means of treating PAES, whereas surgery may not be required for cases of asymptomatic PAES even in patients with a bilateral presentation.

    一名62岁的男性在经皮冠状动脉介入治疗后1天出现短暂性脑缺血发作。磁共振成像显示左半球有新鲜的脑梗死。数字减影血管造影显示左Riles1A型颈总动脉闭塞(CCAO)。颈内动脉(ICA)的血流来自颈外动脉,通过左枕动脉和左椎动脉肌肉分支之间的吻合。我们用隐静脉进行了从CCA到ICA的短跳移植,然后结扎CCA。在1年的随访中,移植物仍保持专利。
    A 62-year-old man was presented with transient ischemic attack 1 day after percutaneous coronary intervention. Magnetic resonance imaging demonstrated fresh cerebral infarction in the left hemisphere. Digital subtraction angiography showed left Riles type 1A common carotid artery occlusion (CCAO). Blood flow in the internal carotid artery (ICA) was derived from the external carotid artery, which came through the anastomosis between the left occipital artery and a muscular branch of left vertebral artery. We performed short jump graft from CCA to ICA using saphenous vein, followed by ligation of CCA. The graft remained patent at the 1-year follow-up.

    手术切除仍然是肝肿瘤治疗的最佳选择。肝切除术结合人工血管重建已被证明是治疗涉及肝主要静脉的肿瘤的替代方法。作为尖端的外科技术,机器人肝脏手术是一种新的程序,扩大了微创方法的领域,特别是在复杂的重建中。这项研究报告,第一次,使用膨胀聚四氟乙烯(ePTFE)移植物对患有肝腺瘤的患者进行机器人肝切除术,并进行肝中静脉(MHV)重建。肿瘤,位于第8段,与MHV相邻。机器人辅助切除第4段和部分第8段,并使用ePTFE移植物进行MHV重建。在术后检查和随访期间,ePTFE移植物的血流是专利的,肝功能恢复良好。因此,机器人肝切除术与MHV重建是一种安全的,微创,和精确的手术,可以为侵袭或邻近主肝静脉的肝肿瘤患者提供一种新的方法。
    Surgical resection remains the best choice for the treatment of liver tumors. Hepatectomy combined with artificial vascular reconstruction has been proven as an alternative to treating tumors involving the main hepatic veins. As the cutting-edge surgical technique, robotic liver surgery is a novel procedure expanding the field of minimally invasive approaches, especially in complex reconstruction. This study reports, for the first time, on a robotic hepatectomy with middle hepatic vein (MHV) reconstruction using an expanded polytetrafluoroethylene (ePTFE) graft for a patient with hepatic adenoma. The tumor, which was located in segment 8, was adjacent to the MHV. Robot-assisted resection of segment 4 and partial segment 8, and MHV reconstruction using a ePTFE graft were performed. During the post-operative examination and follow-up, the blood flow of the ePTFE graft was patent, and liver function recovered well. Thus, robotic hepatectomy with MHV reconstruction is a safe, minimally invasive, and precise surgery that may provide a novel approach for patients with liver tumors that are invading or adjacent to the main hepatic veins.

    一名患有Leriche综合征的47岁男性,由于TASCII型D型闭塞远端主动脉和总动脉而出现数字坏疽。使用Dacron主动脉-biliac旁路移植物进行开放式血运重建;然而,术后病程显示,他在戒断性精神病期间有未披露的静脉阿片类药物滥用史.我们的报告重点介绍了在可疑或确诊的静脉吸毒者中减轻与人工主动脉移植物相关的感染风险的方法。文献综述提出了替代策略,如主动脉动脉内膜切除术,使用非覆盖支架的全血管内途径,或混合方法。自体静脉移植物的主要使用应被视为最后的手段,以便在移植物感染的情况下保留静脉以供将来使用。患者因素,如合并症,适合接受手术,咬合的解剖学范围,由于缺乏基于证据的准则,设施/专门知识的可用性可以进一步指导管理计划。
    A 47-year-old male with Leriche syndrome presented with digital gangrene due to TASC II type-D occlusion of the distal aorta and common iliac arteries. Open revascularization was performed using a Dacron aorto-biiliac bypass graft; however, the postoperative course revealed a nondisclosed history of intravenous opioid abuse as he went into withdrawal psychosis. Our report highlights ways to mitigate infection risk associated with prosthetic aortic grafts in suspected or confirmed intravenous drug abusers. The literature review suggests alternative strategies like aortoiliac endarterectomy, total endovascular approach using non-covered stents, or a hybrid approach. The primary use of autologous venous grafts should be considered as a last resort so that the veins are retained for future use in case of graft infection. Patient factors like comorbidities, fitness to undergo surgery, anatomical extent of occlusion, and availability of facilities/expertise can further guide the management plan owing to a lack of evidence-based guidelines.

    Intraoperative iliac artery dissection during kidney transplantation is a rare but serious complication that requires prompt intervention. We present a case of right external iliac artery dissection during deceased donor kidney transplantation. A 57-year-old male patient underwent standard pretransplant evaluation and had no signs of either significant aortoiliac occlusive disease or peripheral arterial occlusive disease. Diabetic nephropathy, arterial hypertension and smoking were the underlying causes of the patient\'s end-stage renal disease. Transplantation was performed in the standard fashion. The kidney was positioned in the right iliac fossa and the venous end to-side anastomosis was performed first. A significant dissection of the right external iliac artery was found on arteriotomy. Immediate ilio-femoral bypass with a vascular prosthesis was performed. During two years of follow-up the kidney function is stable and there are no signs of lower limb vascular insufficiency.

    Presented in the article is a clinical case report regarding successful treatment of a patient with infection of a vascular graft after bifurcation aortofemoral bypass grafting by means of partial removal of the graft\'s branch with extra-anatomical graft-to-femur prosthetic repair through the iliac wing. The patient was admitted 6 months after bifurcation aortofemoral bypass grafting with a purulent and ligature fistula, discharge in the inguinal area. The findings of computed tomography showed no infection of the central anastomosis in the retroperitoneal space, with however periprosthetic infection in the area of the distal branch and severe comorbid background, thus not allowing complete removal of the prosthesis. A decision was made to perform operation in the scope of resection of the graft\'s branch, with extra-anatomical bypass grafting through a hole created in the iliac wing and debridement of the wound in the groin. In the postoperative period, no lower limb ischemia was observed, with blood circulation compensated completely. The patient was discharged in a satisfactory condition on POD 64 with no signs of either local or systemic infection.
    В статье представлен клинический случай успешного лечения пациента с инфекцией сосудистого протеза после бифуркационного аорто-бедренного шунтирования путем частичного удаления бранши протеза с экстраанатомическим протезо-бедренным протезированием через крыло подвздошной кости. Пациент поступил спустя 6 мес. после бифуркационного аорто-бедренного шунтирования с лигатурным и гнойным свищом, отделяемым в паховой области. По данным компьютерной томографии инфицирования центрального анастомоза в забрюшинном пространстве не было, однако имелась парапротезная инфекция в области дистальной бранши и наблюдался тяжелый коморбидный фон, что не позволяло выполнить полное удаление протеза. Было принято решение об операции в объеме резекции бранши протеза с проведением экстраанатомического шунтирования через созданное отверстие в крыле подвздошной кости с дебридментом и санацией раны в паху. В послеоперационном периоде ишемии нижних конечностей не отмечено, кровообращение полностью компенсировано. Пациент выписан в удовлетворительном состоянии на 64-е сутки после вмешательства без признаков местной и системной инфекции.

    探讨脉络膜前动脉(AChA)区圈闭部位与脑梗死的关系及颈内动脉血泡样动脉瘤(BLA)高流量分流术和病灶圈闭治疗的相关风险。
    我们纳入了26例诊断为BLAs并接受高流量旁路和诱捕的患者。我们检查了临床特征,包括年龄,动脉瘤陷阱位置,最终预后,脑梗塞术后磁共振成像,出院时改良Rankin量表评分。我们还搜索了类似研究的文献。
    20例患者出院时改良Rankin量表评分为0-2分,2名患者中有3-5名,2例患者中有6例。在19/26患者(73.1%)中,被困段位于后交通(PcomA)和眼动脉之间。在2例患者(7.7%)中,被困节段包括PcomA和AChA;4例患者(15.4%),被困段在PcomA内。在这些患者中,PcomA被阻塞,高流量旁路的血液单独流向AChA。无患者出现脑梗死。我们的系统评价确定了70例患者。在所有96名患者中,12人患有AChA脑梗塞;然而,梗死仅影响2例患者的预后。
    当用高流量旁路和病灶捕获治疗BLAs时,即使PcomA闭塞,AChA脑梗死的频率也很低,在高流量旁路期间,将AChA作为唯一的流出血管。然而,治疗C1-2附近晚期动脉硬化患者时,PcomA闭塞可能与风险相关。
    To examine the relationship between trap location and cerebral infarction in the anterior choroidal artery (AChA) region and associated risks in ruptured internal carotid artery blood blister-like aneurysm (BLA) treatment with high-flow bypass and lesion trapping.
    We included 26 patients diagnosed with BLAs and treated with high-flow bypass and trapping. We examined clinical characteristics including age, aneurysm trap location, final prognosis, cerebral infarction on postoperative magnetic resonance imaging, and modified Rankin Scale score at discharge. We also searched the literature for similar studies.
    The modified Rankin Scale score at discharge was 0-2 in 20 patients, 3-5 in 2 patients, and 6 in 2 patients. In 19/26 patients (73.1%), the trapped segment was between the posterior communicating (PcomA) and the ophthalmic arteries. In 2 patients (7.7%), the trapped segment included the PcomA and the AChA; in 4 patients (15.4%), the trapped segment was within the PcomA. In these patients, the PcomA was occluded, and blood from the high-flow bypass flowed out to the AChA alone. No patient showed cerebral infarction. Our systematic review identified 70 patients. Of all 96 patients, 12 had AChA cerebral infarction; however, the infarction affected the prognosis of only 2 patients.
    When treating BLAs with high-flow bypass and lesion trapping, the frequency of AChA cerebral infarction is low even when the PcomA is occluded, leaving the AChA as the only outflow vessel during high-flow bypass. However, PcomA occlusion may be associated with risks when treating patients with advanced arteriosclerosis near C1-2.
