Application value of high-pressure-resistant peripherally inserted central catheters in enhanced computer tomography of diabetic patients with malignant tumors

Table 1 Symptoms and grades of iodine contrast extravasation

Symptom	Grade
No obvious symptoms	0
Edema diameter < 2.54 cm	1
2.54 cm < edema diameter < 15.24 cm	2
Translucent edema (diameter > 15.24 cm)	3
Edema diameter > 15.24 cm, combined with blood oozing, circulatory disturbance, and moderate to severe pain	4

Table 2 Contrast-enhanced computed tomography imaging quality grading

Image	Grade
Clear vascular display and no artifacts or only a few artifacts, which does not affect the diagnosis	Good
Blurred development of important blood vessels or interrupted display of blood vessels, with a large number or all artifacts in arteries, which cannot be used for diagnosis	Poor
