What should I do if I have an extravasation during a scan?
If contrast extravasation happens, we will have you raise your arm above the level of your heart and apply a cold compress to the IV site. An ice pack also helps to limit any pain you may have—both while you are at the medical center and over the next few days. After you leave the Radiology Department, follow these steps:
What is contrast extravasation in a CT scan?
Extravasation of non-ionic CT contrast media appears to be innocuous and can be treated with conservative therapy. Plastic surgery consultation should be obtained when there are obvious signs of skin and soft tissue compromise or symptoms of compartment syndrome.
What is extravasation and how is it treated?
Jan 30, 2015 · Contrast media (CM) are widely used in in computed tomography (CT) examination. CM may lead to various adverse reactions that may occur immediately (in the hour following the injection) or later (up to a week after the injection). The possible adverse reactions are an extravasation of CM, allergic, cardiovascular or renal reactions [ 1 ].

What is extravasation in medicine?
Extravasation refers to the leakage of injected drugs from blood vessels causing damage to the surrounding tissues. Common symptoms and signs of extravasation include pain, stinging or burning sensations, and edema around the intravenous (IV) injection site.
How to stop IV fluids from extravasation?
At the first sign of extravasation, the following steps are recommended: (1) stop administration of IV fluids immediately, (2) disconnect the IV tube from the cannula, (3) aspirate any residual drug from the cannula, (4) administer a drug-specific antidote, and (5) notify the physician (Fig. 1). Open in a separate window.
What happens if you have a tendon injury?
While the injury is usually minor and resolves spontaneously, some cases result in serious complications, including full-thickness skin loss and muscle and tendon necrosis requiring reconstructive surgery or even amputation, leading to longer hospital stays, increased morbidity, and increased costs. Pain .
Can a patient be unable to work?
Patients may be unable to work for some time; quality of life must be compensated for if a patient’s occupation requires full physical mobility, and exposure of the disfigurement in public can cause a psychological impact. Medical expense .
Why is IV fluid a high risk?
Because errors associated with IV administration can result in fatal or life-threatening outcomes , administration of IV fluids and medications can be a high-risk, with adverse outcomes potentially leading to malpractice claims. An incident of extravasation must be correctly documented and reported.
What are physical defects?
Physical defects . Patients may be unable to work for some time; quality of life must be compensated for if a patient’s occupation requires full physical mobility, and exposure of the disfigurement in public can cause a psychological impact.
When to use extravasation?
Strictly-speaking, 'extravasation' should be used for leakage of contrast from blood vessels only. However it is widely used in a more general sense when contrast escapes from any normal anatomical structure into the surrounding soft tissues, e.g. leak of contrast medium from the renal tract after iatrogenic ureteric injury.
What is CMEV in CT scan?
Contrast media extravasation ( CMEV ) refers to the leakage of intravenously-administered contrast media from the normal intravascular compartment into surrounding soft tissues; it is a well-known complication of contrast-enhanced CT scanning. It can also occur in MRI studies, but the complications are rare given the low volumes that are used. Occasionally extravasation also happens in fluoroscopy, but due to the combination of a slow manual injection, small boluses and the visualization in real time of the contrast passing into the blood vessel, it is rarely an issue.
Does contrast media reduce soft tissue injury?
Non-ionic low-osmolar contrast media are known to reduce the risk of severe soft tissue injury, but the potential for soft tissue injury is often related to the volume of contrast media that extravasates 1.
What is extravasation in cancer?
Extravasation is a process through which a liquid, maybe a drug or a fluid leak into a surrounding tissue accidentally. In case of inflammation, it indicates white blood cells (WBC) movements from capillaries to tissues, also called diapedesis. In malignant cancer metastasis, the term is used to mean involuntary permeation ...
How long does extravasation last?
Shoulder pain. The late effects of extravasation are: Marked induration that may last between days to months.
How to tell if a drug is extravasated?
The early symptoms of extravasation include the following: 1 Swelling, pain, erythema, and blistering. These signs may be absent initially if the drug leaks into the tissue slowly after completion of the drug administration. 2 Shoulder pain.
What are the two types of local reactions caused by extravasation?
The extravasation agents cause two kinds of the local reactions: irritant and the vesicant reactions. An irritant reaction happens as temporary phlebitis. However, the extravasation of the vesicant drugs like the anthracyclines can cause reactions that can include damage to the progressive tissue, which may progress during the days and the weeks.
What is prompt intervention?
Immediate treatment measures include a prompt intervention when the extravasation is suspected. Leakage of bodily fluids and drugs may also take place due to other reasons as well like infiltration. As such, extravasation and infiltration are two different occurrences.
After the CT Scan
If the patient received a contrast injection, the IV is removed from the arm before going home. There should be no ill effects from the scan or the contrast injection. In the rare circumstance that the patient received sedation, they will be sent home once they are awake and alert. However, someone will have to drive the patient home.
When to seek medical care
The reaction to the contrast is almost always immediate, so it is very rare to have a reaction after the patient leaves the facility. However, if a patient thinks they are having a delayed reaction to the contrast, they should call the facility where they had the exam.
What are the risks of IV extravasation?
Risks for extravasation are multifactorial and are largely modifiable. Many of these risks stem from errors in device use and placement. IV device factors that affect extravasation risk include needle material (i.e., metal), cannula size (large plastic vs. small plastic), and catheter type (i.e., central venous catheter [CVC]). Metal needles may cause more damage on insertion and are inflexible within the vessel, while large-gauge needles may impede blood flow, slowing the dilution of infusate. 18,19 Extravasation from CVCs can occur with needle displacement from an implanted venous access port (IVAP), mechanical occlusion and subsequent CVC damage, catheter migration, or fibrin sleeve formation and thrombosis. Incorrect placement of IVAP is more likely to occur in patients with new devices, those with significant postoperative swelling, and obese patients or large-breasted women. 20 Mechanical occlusions may be due to thrombus formation, drug precipitate, retrograde catheter displacement, or pinch-off (i.e., an intermittent and positional catheter occlusion; it should be suspected if infusion occlusion can be relieved by having the patient move their arm positioning). 2,21,22 Avoidance of extravasation highly depends on proper maintenance of the IV site and ensuring that the correct rate of infusion is being implemented. These risk factors are related to the antineoplastics used, the patients, and the clinician administering the drug.
What are the complications of IV infusion?
Infiltration and extravasation are two well-known, distinct complications of IV infusion therapy. According to the Infusion Nurses Society and the Oncology Nursing Society, both complications involve the inadvertent leakage of an IV solution into surrounding tissue; however, the type of solution differs.
What is the role of a pharmacist?
The pharmacist’s role would be to help develop policies that will ensure the proper verification, labeling, and dispensing of chemotherapeutic agents. One way this could be executed is to use discriminative labeling when dispensing vesicant antineoplastics so that nurses use the appropriate precautionary measures.
Answer: Extracapsular rupture of silicone implant
Thank you for providing the exact quote from the radiologist's report. I'm not sure who "MD" is, though I would assume it is your primary care provider. You said this was an incidental finding, so presumably you had another reason to get a chest CT scan, which may impact your care. The bottom line is, you need to see a plastic surgeon.
Answer: BBA
You need to see a BC PS. If you were my patient, I would recommend removing the implants and silicone. It is up to you whether you replace the implants or not.Best,
Answer: Ruptured implant
If you were my wife or mother and assuming they were in good health, I would recommend removing the old implants and capsules and extravasation of silicone. It would then be their choice if they wanted to replace with new implants. Dr. Corbin
