概括
严重的左常见阴静脉 (LCIV) 压缩在青少年中很常见,超过50%的13-20岁无症状患者表现出显著的狭窄. 这一发现可能是正常的解剖学变异,不一定是深静脉血栓形成的危险因素.
科学领域:
- 血管医学 血管医学
- 放射学 放射学是指放射学
- 儿科健康 儿科健康
背景情况:
- 阴茎结合处的静脉压缩是深静脉血栓形成的已知危险因素.
- 标准的管理包括静脉支架.
- 之前的研究集中在成年人群中,在了解儿科静脉解剖学方面留下了一个差距.
研究的目的:
- 为了确定21岁以下无症状患者左侧常见阴静脉 (LCIV) 狭窄的患病率.
- 为了比较年轻人与老年人的LCIV压缩率.
- 为了在儿科患者中为下静脉压缩提供治疗决策的信息.
主要方法:
- 对13-20岁患者CT成像的回顾性审查,以非血管指示.
- 对照组包括35-65岁的患者,具有相似的CT指示.
- 两个独立的检查员评估了LCIV在交汇处的直径,并将其与非压缩的脉直径进行了比较.
主要成果:
- 超过50%的13-20岁无症状患者 (55.7%) 呈现≥70%的LCIV狭窄.
- 在儿科组中,LCIV直径狭窄的平均值为69.4%.
- 相比之下,只有1.7%的老年人 (35-65岁) 出现了类似的严重狭窄 (P < .001).
结论:
- 严重的LCIV压缩是无症状青少年 (13-20岁) 的常见解剖发现.
- 这种高发病率表明LCIV缩小可能是这个年龄组的正常变异,而不是DVT的直接风险因素.
- 在年轻患者中,对静脉压缩进行常规干预可能不需要.

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...

The human body is a complex system of interconnected parts, and the circulatory system plays a crucial role in maintaining overall health. One key component of this system is the inferior vena cava, a large vein responsible for returning blood from the abdominopelvic viscera and abdominal walls to the heart.
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the...

The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...
