まとめ

医原性外頸静脈仮性動脈瘤は、頸部処置後のまれな合併症である。この症例は、頸部嚢胞の超音波ガイド下吸引の数年後の異常な発現を強調するものである。

科学分野:

血管外科
放射線科
医学的症例報告

背景:

外頸静脈仮性動脈瘤はまれな血管病変である。
以前に報告された原因には、自発性または先天性要因が含まれる。
医原性原因、特に医療介入後のものは、文書化されることが少ない。

研究の目的:

医原性外頸静脈仮性動脈瘤のまれな症例を報告する。
この病状の穿刺吸引後の異常な発現を記述する。
このような症例の診断および管理上の考慮事項について論じる。

主な方法:

72歳女性患者が頸部腫瘤を呈した。
初期治療には、嚢胞性腫瘤の超音波ガイド下針吸引が含まれた。
仮性動脈瘤の診断は、ドップラー超音波検査およびCTアンギオグラフィーによって確認された。

主要な成果:

医原性外頸静脈仮性動脈瘤が特定された。
仮性動脈瘤は約4年後に吸引処置が行われた後に出現した。
病変は無症候性で、左鎖骨上窩領域に位置していた。

結論:

穿刺吸引は、遅発性の医原性仮性動脈瘤形成につながる可能性がある。
無症候性の静脈性仮性動脈瘤は、臨床的および画像的フォローアップを伴う保存的治療を必要とすることが多い。
この症例は、頸部腫瘤の鑑別診断において医原性原因を考慮することの重要性を強調するものである。

Adult Mouse Venous Hypertension Model: Common Carotid Artery to External Jugular Vein Anastomosis.

We describe a method for creating a reliable model of cerebral venous hypertension in the adult mouse. This model has been widely described and tested in the rat. This new counterpart in the mice opens the possibility of using genetic modified animals and thereby broadens the applications of the...

Jugular Vein Graft Harvest From a Rabbit Model: A Surgical Procedure to Excise a Segment of Rabbit Jugular Vein for Ex Vivo Studies

In this video, we demonstrate a procedure for surgically harvesting a segment of the jugular vein from a rabbit model. The resected segment can be used as an autologous vein graft to study intimal hyperplasia that develops due to arterial blood...

Veins of Head and Neck

Veins of Head and Neck

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...

Catheter Based Intravenous Injection of Experimental Agents: A Technique for Delivering Experimental Agents Intravenously Through Jugular Vein in Mouse Model

In this video, we describe a method for implanting a catheter into the jugular vein of a mouse model through which experimental agents such as drugs and tracer dyes can be delivered intravenously in vivo. Such an arrangement when connected to other systems can also be used for monitoring hemodynamics and blood...

Microsurgical Skills of Establishing Permanent Jugular Vein Cannulation in Rats for Serial Blood Sampling of Orally Administered Drug

Detailed microsurgical techniques are demonstrated to establish a longer-term jugular vein cannulation rat model for sequential blood collection in the same animal. Physiological and hematological parameters have been monitored during the rat's recovery phase. This model has been applied to study pharmacokinetics of orally administered polyphenol without inducing animal...

Catheterization of the Carotid Artery and Jugular Vein to Perform Hemodynamic Measures, Infusions and Blood Sampling in a Conscious Rat Model

Vascular accesses to measure hemodynamics, provide fluids and perform blood sampling are important to any small animal model study. We present a technique for implanting catheters into the carotid artery and the common jugular vein in an anesthetized rat for connecting to a system to perform monitoring, infusions and...
