概括
像特洛拉德静脉和拉贝静脉这样的表面脑静脉显示出显著的解剖变异性. 这种使用MRV的详细形态测量分析对于安全的神经外科手术规划和尽量减少静脉损伤至关重要.
科学领域:
- 神经外科 神经外科
- 放射学 放射学是一门学科.
- 人类解剖学 人类解剖学
背景情况:
- 大脑的表面静脉,包括Trolard静脉 (VT),Labbé静脉 (VL) 和表面Sylvian静脉 (SSV),对于静脉排水至关重要.
- 了解它们的形态特征和解剖学变异对于神经外科干预至关重要.
- 之前的研究已经提供了基础数据,但需要更新分析,以反映当前的成像能力和手术技术.
研究的目的:
- 使用磁共振静脉学 (MRV) 对特罗拉德静脉 (VT),拉贝静脉 (VL) 和表面西尔维亚静脉 (SSV) 进行详细的形态分析.
- 将这些形态测量结果与现有文献进行比较.
- 评估这些表面脑静脉中观察到的解剖学变异的临床和外科影响.
主要方法:
- 从2020年至2024年期间获得的154名个人 (105名女性,49名男性;平均年龄42.12±16.39岁) 的MRV扫描的回顾性分析.
- 对VT,VL和SSV的存在,长度,中点直径,航线,排水模式,主导地位和相互连接的双边评估.
- 使用了统计分析,包括千平方,独立t测试,曼-惠特尼U,皮尔森相关性和霍尔姆-邦费罗尼校正.
主要成果:
- 特罗拉德静脉 (VT) 是最常见的 (88.3%右,76.6%左),主要在后中心区域. 拉贝静脉 (VL) 在74.0% (右) 和66.9% (左) 的患者中存在,通常流入横侧鼻. 表面西尔维亚静脉 (SSV) 在74.3% (右) 和63.6% (左) 的病例中被确定.
- 在右VL和SSV之间 (p=0.0003) 和在左VT和右SSV之间 (p=0.0385,在校正后不显著) 发现了显著的关联.
- 静脉瘤在右半球占主导地位,而静脉瘤在左半球更为普遍. 没有发现与形态参数的年龄相关的相关性.
结论:
- 表面脑静脉在形态和排水模式上表现出显著的解剖变异性.
- 对这些变异的彻底理解对于有效的神经外科规划至关重要,特别是在横向和跨西尔维亚方法中.
- 这项研究提供了最新的形态测量数据,以帮助尽量减少手术过程中的静脉损伤,并指导未来的解剖和手术研究.

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
270
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Veins of Head and Neck
5.0K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
