Introduction
Mechanical venous injury may be associated with internal contusions, fractures, phlebitis, and other conditions. This situation commonly occurs during the placement of indwelling catheters or due to improper techniques when administering local injections. When an indwelling catheter is inserted locally, rolling of the catheter may damage the vein, leading to such injury. Similarly, injecting medication may also injure the vein if the needle punctures the venous wall, potentially causing this condition.
Mechanical venous injury may be associated with internal contusions, fractures, phlebitis, and other conditions.
1. Internal Contusion
This commonly occurs during the placement of indwelling needles or due to improper procedures when administering local injections. When an indwelling needle is inserted locally, movement or rolling of the needle may damage the vein. Similarly, during drug injection, if the needle punctures the vein and causes trauma, it may also lead to such injury.
2. Fracture
When a patient experiences significant local impact causing bone displacement, the displaced bone may directly penetrate into a vein, resulting in mechanical venous injury. In severe cases, this may even lead to massive hemorrhage.
3. Phlebitis
This is often caused by prolonged bed rest or varicose veins, which produce noticeable irritation to local veins, or by bacterial infections triggering inflammatory responses. Under stimulation by inflammatory factors, veins become susceptible to damage.
In addition to the above-mentioned causes, certain blood disorders may also contribute to this condition. Patients are advised to seek timely medical evaluation at a qualified hospital to determine the underlying cause.
