Extravasation is the leakage of intravenously (IV) infused, and potentially damaging, medications into the extravascular tissue around the site of infusion. The leakage can occur through brittle veins in the elderly, through previous venipuncture access, or through direct leakage from wrongly positioned venous access devices.
Risks of complications of the procedure includes: pyelosinus extravasation (contrast going into renal sinus) and pyelotubular (contrast going into collecting duct) reflux of contrast due to overfilling of the urinary system. It can cause pain, fever and chills.
The diagnosis of esophageal perforation could also be confirmed by water-soluble contrast esophagram (Gastrografin), which reveals the location and extent of extravasation of contrast material. Although barium is superior in demonstrating small perforations, the spillage of barium sulfate into the mediastinal and pleural cavities can cause an ...
Extravasation of irrigation fluid is the unintended migration of irrigation fluid (e.g., saline) introduced into a human body.This may occur in several types of endoscopic surgery, such as minimally invasive orthopedic surgery, i.e., arthroscopy, TURP (trans-urethral resection of the prostate), and TCRE (trans-cervical resection of the endometrium).
In a review by Tyler et al., an analysis across the included studies found the overall complication rate associated with IO infusions to be less than 1% (0.9%). [12] Complications include: Bone fractures from the puncture devices; Catheter misplacement which can lead to extravasation
Possible complications include: Pain on injection, Post procedural infection, Ductal rupture, Extravasation of contrast media, Allergic reaction to iodinated contrast media (which may present with urticaria, dyspnoea, and hypotension).
European guidelines classify a pre-existing decreased kidney function to be a risk factor of contrast-induced nephropathy in the following cases: [5]. Estimated glomerular filtration rate (eGFR) < 45 ml/min/1.73 m 2 of body surface area before intra-arterial administration with first-pass renal exposure (not passing lungs or peripheral circulation before kidneys), or in the intensive care unit
Contrast agent is injected through the catheter, and when abnormal findings are observed, such as systemic–pulmonary shunts, proliferations of the capillary vessels, or extravasation of the contrast medium to the lung tissues, they were super selectively embolized using the 3 Fr microcatheter system.
