The evaluation of intracranial bypass patency in neurosurgical practice

BackgroundThe patency of cranial bypasses must be carefully evaluated during and after the microsurgical procedure. Although, several imaging techniques are used to evaluate the patency of bypasses, their findings are sometimes difficult to interpret.PurposeThe goal of this study was to assess the consistency of different diagnostic modalities for evaluating intracranial bypass patency.Patients and methodThis prospective study included 19 consecutive patients treated with EC-IC or IC-IC bypass for MoyaMoya disease (MMD) or complex/giant aneurysms between June 2016 and June 2018. In the early postoperative period (< 7 days), all patients had transcranial Doppler (TCD), CT angiography (CTA) and MRA to demonstrate patency of anastomoses and to confirm exclusion of the aneurysm. When findings of anastomosis patency differed between these techniques, conventional angiography was performed.ResultsAll anastomoses were patent on indocyanine green videoangiography at the end of microsurgical procedure. The results of noninvasive postoperative exams were consistent to demonstrate the patency of anastomoses in 13 patients. In 4 patients, a discrepancy in patency of anastomoses arose between TCD, CTA and MRI in the early postoperative period. In 2 other patients, the interpretation of bypass patency remained inconclusive before the decision to occlude the aneurysm. In these 6 patients, a significant edema was noted in 2 cases, a postoperative subdural hematoma in 1 case, a low flow in the anastomosis in 1 case and vasospasm in 2 cases. The anastomosis was patent on the conventional angiography in five patients.ConclusionNoninvasive imaging techniques provide useful data about the patency but their findings should be carefully interpreted due to local anatomical, physiological, and pathological factors. In case of discrepant findings, conventional angiography including supraselective catheterization of the donor vessel is suggested.     

腹腔镜右半结肠癌切除术后消化道重建的研究现状及前景

腹腔镜右半结肠癌切除术后腹腔内吻合正逐渐成为结直肠手术领域中的热点。研究者发现:腹腔内吻合与腹腔外吻合比较,前者在促进病人术后恢复,降低术后并发症发生率等方面有潜在优势。且腹腔内吻合较腹腔外吻合病人术后胃肠功能恢复更快、术后疼痛评分更低。但对于腹腔内吻合的并发症发生率,尤其是重要指标吻合口漏的比较,尚缺乏足够证据。而手术技术不统一、吻合口漏定义不明确是目前研究的主要困难。多项高质量的前瞻性随机对照试验目前正在进行中,对于腹腔镜右半结肠癌切除术的客观评价仍需要更高级别的循证医学证据验证。笔者综合分析国内外研究进展,系统阐述腹腔镜右半结肠癌切除术后消化道重建的研究现状及前景,旨在为我国结直肠外科临床研究探索新方向。     

搭桥、分流手术中分流管端侧交接缝合处的受力分析

本文对搭桥分流术中分流管端侧交接缝合处受力进行了分析，发现分流管向的张力随分流管面积与动脉管面积的比值增大而增大，并且在流量比为０．３时该张力有最小值。夹角的影响不大，但不可忽略。考虑到缝合材料等其它因素，还需建立对缝合线密度等因素的要求。
