What five conditions must be satisfied before a percutaneous procedure can be performed? • The patient or patient representative must provide written, informed consent for the procedure, intravenous conscious sedation (if applicable), and potential administration of blood or blood products. • Code status during the procedure and postprocedural recovery period must be determined if the patient has …
When is an image guided percutaneous core biopsy required as opposed to a percutaneous fine-needle aspiration (FNA)? When architectural detail is needed for histopathologic diagnosis (e.g., well-differentiated neoplasms) and staging (e.g., staging fibrosis of diffuse liver diseases), a core biopsy is required. FNA specimens are usually obtained using 22- to 25-gauge needles and yield clusters …
Contraindications (absolute or relative) for image-guided PNB and PFA/PCD • A competent patient who does not give consent • A patient who is unwilling or unable to cooperate with or to be positioned for the procedure (e.g., a retroperitoneal abscess is only accessible percutaneously via the back but the patient is unable to lie prone because of …
Indications for image guided percutaneous fluid aspiration (PFA) and percutaneous catheter drainage (PCD)? • Obtain a sample for fluid characterization. • Remove fluid suspected to be infected or the result of an abnormal fistulous connection. • Remove a fluid collection suspected to be the cause of symptoms sufficient to warrant drainage. • Perform an adjunctive procedure necessary to facilitate …
Indications for image guided percutaneous needle biopsy (PNB)? • Establish a benign or malignant diagnosis of a lesion. • Stage patients with known or suspected malignancy when metastasis is suspected. • Obtain material for microbiological analysis in patients with known or suspected infection. • Determine the nature and extent of diffuse parenchymal diseases (e.g., cirrhosis, organ transplant rejection, glomerulonephritis).
Compare open surgical versus percutaneous endovascular treatment for patients with chronic mesenteric ischemia. Endovascular treatment with percutaneous angioplasty and stenting is minimally invasive and thus has better short-term morbidity and mortality than open surgical repair. Open surgical repair, however, is more durable and has a decreased reintervention rate compared with endovascular therapy.
role of endovascular therapy in patients with acute occlusive mesenteric ischemia? The primary goal of any treatment is revascularization of the affected bowel to restore normal function and prevent infarction. Open surgery has traditionally been the standard of care. Endovascular techniques including aspiration embolectomy, thrombolysis, and stenting have been successfully described in the literature to …
