目的 :研究中国人恒牙根管系统中侧副管的解剖形态 ,为牙髓治疗提供依据。方法 :用透明标本法将3 80 3个恒牙依次作髓腔染色 ,5 %盐酸脱矿 ,酒精系列脱水 ,置入冬青油中制成透明牙。结果 :观察到的侧副管有 5型 :根管侧支、根尖分歧、根尖分叉、管间吻合和旁管。统计各型侧副管在不同牙位、同一牙位不同根管中的发生率。结论 :侧副管解剖形态在不同牙位、同一牙位的不同根管中具有一定规律性 ,掌握其分布规律具有重要临床意义。

Background and Study Aims: Portal hypertension often coexists with pancreatic pseudocysts and is potentially dangerous if a collateral vessel is in the vicini ty of the needle puncture pathway. Hitherto, there have been no reports of pseud ocyst drainage in this setting. Patients and Methods: Patients who underwent end oscopic ultrasound (EUS)-guided pancreatic pseudocyst drainage complicated by i ntervening vessels were assessed for success and outcomes. An Olympus mechanical linear-array video echo endoscope GF-UM 140D was used for the drainage proced ure in all patients. Either a “hot"diathermy technique was employed or a “cold " technique using direct aspiration with a 19-G needle, followed by deployment of a nasocystic catheter. Results: Eight patients with a symptomatic pseudocyst and intervening vessels underwent drainage that was guided (n = 6) or assisted ( n = 2) by EUS. All were found to have successful resolution of the cyst at follo w-up 6 weeks later, while segmental portal hypertension had disappeared in one patient. There were no major *** patient had transient hemorrhagic drainage that resolved by itself. Conclusions: Pseudocysts complicated by porta l hypertension or by intervening vessels can be safely drained under EUS guidanc e, even in the absence of color Doppler imaging.

息肉状脉络膜血管病变的息肉状损害的可塑性

Purpose: The aim of this study was to describe the clinical course in a patient with polypoidal choroidal vasculopathy (PCV). Methods: A 68- year- old man with PCV in the left eye was followed up by means of routine examinations including fluorescein angiography and indocyanine green angiography for over 60 months. Results: Throughout the follow- up period, the patient experienced repeated lesions in the macula, such as serosanguineous detachment of the retinal pigment epithelium and neurosensory retina, but retained good visual acuity. Indocyanine green angiography disclosed spontaneous regression of polypoidal vessels followed by significant changes in the choroidal circulation: a group of polypoidal structures disappeared, and after several months a small choroidal vessel became apparent that was distant from the previously observed polypoidal structure rather than representing an extension of the original lesion. Conclusion: The clinical observation suggests that in some cases of PCV the choroidal vasculature may be altered with time, in that some vessels in the inner choroid and even the choriocapillaris may close and collateral vessels and/or new vessels may develop to form complex such as that described here.
