Atypical Developmental Venous Anomaly Associated with Single Arteriovenous Fistula and Intracerebral Hemorrhage: a Case Demonstrated by Superselective Angiography

We present a case of developmental venous anomaly associated with arteriovenous fistula supplied by a single arterial feeder adjacent to a large acute intracerebral hemorrhage. The arteriovenous fistula was successfully obliterated by superselective embolization while completely preserving the developmental venous anomaly. Two similar cases, including superselective angiographic findings, have been reported in the literature; however, we describe herein superselective angiographic findings in more detail and demonstrate the arteriovenous shunt more clearly than the previous reports. In addition, a literature review was performed to discuss the association of a developmental venous anomaly with vascular lesions.     

High frequency region of the snore spectra carry important information on the disease of sleep apnoea

Snoring is the most common symptom of obstructive sleep apnoea (OSA). Several researchers have reported differences between the power spectra of non-OSA and OSA snorers. The traditional approach over the years has been to record snore sounds at a bandwidth of < 5 kHz. Narrowing of the upper airways during OSA events and the resulting upward shift of snore frequencies also lend support to the idea of examining snore sounds beyond 5 kHz. In this paper, we compute the power spectra of snores in three different bands defined as: low-frequency band (LFB: < 5 kHz); middle-frequency band (MFB: 5–10?kHz) and high-frequency band (HFB: 10–20 kHz). We illustrate that there is a significant difference between non-OSA snorers (Apnoea Hypopnoea Index (AHI) < 10) and OSA snorers (AHI > 10) in the region > 5?kHz. We then develop a feature to diagnose OSA based on the spectral differences in the high frequency region and evaluate its performance on a database of 20 subjects. Our results strongly suggest that the high-frequency region of the snore sounds carry information, hitherto disregarded, on the disease of sleep apnoea.

胃大部切除术后合并胆汁瘘7例教训分析

目的通过回顾性分析胃大部切除术后并发胆汁瘘的患者资料，总结临床经验。方法本院7例行毕罗I式胃大部分切除术的患者术后第1—5天并发胆汁瘘，根据患者临床体征及腹部超声检查诊断为胆汁瘘，行胆囊切除胆肠Roux—en—Y吻合术。结果所有患者平均住院（19．2±3．7）d后痊愈出院，无一例患者死亡。结论胃大部切除术操作较为复杂，因此掌握手术适应证、优化手术技术、术后定期胃镜检查，早期发现并治疗并发症可避免发生严重不良后果。
