350例脊髓血管畸形介入治疗的护理分析

目的探讨护理工作在脊髓血管畸形介入治疗中的价值。方法通过对我院介入中心350例脊髓血管畸形患者介入治疗,针对脊髓血管畸形患者的临床特点和介入治疗方法的适应证、操作过程和预后等特点,从护理学的角度对术前、术中、术后等阶段进行讨论分析。结果术前进行有效的心理护理和健康教育;术中与介入医生及技术操作人员进行有机的配合、熟练使用输液微量泵、准确使用相关药物及认真观察病情变化;术后对患者进行严密的护理观察,可减少并发症的发生,将有助于该手术的成功。结论介入护理工作对脊髓血管畸形介入治疗手术的成败起着至关重要的作用。     

Intra-articular arteriovenous malformation of the knee

Two young men with longstanding suprapatellar masses are presented. The initial clinical diagnosis was of a synovial or soft tissue tumour. Magnetic resonance imaging showed the features of an arteriovenous malformation (AVM). Surgical exploration and biopsy confirmed the diagnosis. AVMs, although rare, should be considered as a possible diagnosis of a peri-articular swelling of the knee.     

Hematospermia associated with congenital arteriovenous malformation of internal iliac vessels

The presence of blood in the ejaculate is called hematospermia or hemospermia. While often perceived as a symptom of little significance, hematospermia can cause great concern to men who experience it. We report an unusual case of hematospermia associated with pelvic arteriovenous malformation (AVM). A 60-year-old man who visited our hospital complaining of hematospermia and pollakisuria was found to have AVM and aneurysmal changes in the left side of the pelvis using computed tomography (CT). The patient was treated with steel coil embolization of the left inferior gluteal artery, and after the procedure the hematospermia and pollakisuria remained absent without flare-ups.     

眶内眼动脉瘤合并脑海绵状血管畸形一例并文献复习

目的探讨眶内眼动脉瘤合并连续出血的脑海绵状血管畸形的临床表现特点和诊治要领。方法报告1例眶内眼动脉瘤并发反复出血的脑海绵状血管畸形患者临床资料,并复习相关文献。结果该患者先行脑海绵状血管畸形切除,分期手术作眶内眼动脉瘤夹闭,治疗结果良好。结论眶内眼动脉瘤极其罕见,应个体化制定治疗方案;手术夹闭动脉瘤颈是眶内眼动脉瘤的首选治疗方法。     

大鼠气管上皮细胞体内—体外转化模型的研究

本研究建立了大鼠气管上皮细胞体内－体外转化模型，大鼠气管内滴注苯并芘，三天后处死大鼠，消化气管上皮细胞，接种于无血清完全培养基。细胞形成集落后，换为选择培养基继续培养五周，统计转化率。结果显示，２５ｍｇ／ｋｇ和５０ｍｇ／ｋｇ的苯并芘可诱导大鼠气管上皮细胞转化及微核增加，用同样方法研究了煤焦沥青提取物，结果表明，剂量为８ｍｇ／ｋｇ和２５ｍｇ／ｋｇ的煤焦沥青提取物能明显诱导大鼠气管上皮细胞转化。     

Bilateral Ulnar Agenesis: Case Report and Review of the Literature

Bilateral ulnar agenesis is a rare abnormality. A total of 36 cases are analyzed: 35 of these are documented in the literature and 1 stillborn male is presented in this study. Most patients had one of the three conditions: Al-Awadi/Raas-Rothschild syndrome, syndrome of ulnar aplasia with split hand/split foot deformity, or the Brachmann—de Lange syndrome. Fifty percent of all cases with bilateral ulnar agenesis were associated with lower limb defects and these cases, for the most part, also belonged to the aforementioned syndromes. Nonskeletal, internal organ malformations were identified in 34% of all patients. Nine patients presented with isolated bilateral ulnar agenesis. The Al-Awadi/Raas-Rothschild syndrome and the split hand/split foot deformity are heritable disorders. There was no evidence for genetic etiology in most of the other cases. Bilateral ulnar agenesis in our fetus was part of the Brachmann—de Lange syndrome with associated cardiac defect, diaphragmatic hernia, and umbilical artery agenesis.     

气管与主支气管肿瘤的影像诊断（附32例报告）

作者对３２例经病理证实的气管与主支气管良、恶性肿瘤的影像学表现进行分析，归纳为３型：腔内型、壁增厚型和腔内外型。后２种类型提示恶性，而无蒂的腔内型表现者不能鉴别良，恶性。作者还评价了常规体层、ＣＴ及ＭＲＩ诊断气管与主支气管肿瘤的优、缺点，讨论了影像诊断的作用。     

Posterior cranial fossa dimensions in the Chiari I malformation: Relation to pathogenesis and clinical presentation

Summary Skull dimensions were measured on lateral skull radiographs in 33 adult patients with MRI-verified Chiari I malformations and in 40 controls. The posterior cranial fossa was significantly smaller and shallower in patients than in controls. In the patients, there was a positive correlation between posterior fossa size and the degree of the cerebellar ectopia, which might indicate that a posterior cranial fossa which was originally too small had been expanded by the herniation of hindbrain structures at an early stage. Pyramidal signs and cerebellar symptoms and signs, which may be due to compression of neural structures, were associated with a large degree of ectopia and a relatively large posterior cranial fossa. Syringomyelia and headache, which may be due to the valve action of the herniated cerebellar tissue, were not associated with a particularly large posterior fossa or herniation. No special clinical presentation was associated with a very small posterior cranial fossa, which may indicate that a small posterior cranial fossa per se has little or no clinical significance, although it may be the primary developmental anomaly.     

Basilar arterio-venous pseudoparallelism due to persistence of embryonal venous pattern

Summary A vascular malformation, consisting of a venous vessel bridgeing the right inferior petrosal sinus and the anterior spinal veins, was found in the posterior fossa. The vessel presented a ring-like course around the right trigeminal root, and it was parallel and dorsal to the basilar artery. The malformation was associated with cutaneous and hepatic angiomas and peri-osteal lipomas. It had been clinically silent for 52 years, when it thrombosed causing death. The authors think that, within a general mesenchymopatic state, this is a result of the persistence of an embryonal cerebral venous pattern.     

新生儿先天性畸形与孕妇乙型肝炎病毒感染关系的研究
