Stellate ganglion block
The stellate ganglion block describes blockade of the cervicothoracic sympathetic chain which provides post-ganglionic sympathetic efferents to the head, neck and upper extremities. Neural blockade is typically acheived by deposition of local anesthetic between the prevertebral fascia and longus...
Peripherally inserted central catheter
Peripherally inserted central catheters (PICCs), often incorrectly tautologically termed PICC lines, are a type of central venous catheter predominantly used amongst oncology patients and those with chronic diseases (e.g. cystic fibrosis). They offer the ability to have long-term central venous...
A Clagett thoracotomy is a three stage procedure performed for treatment severe empyema and involves the resection of a posterolateral lower rib and the formation of an open window in the lateral aspect of the chest to allow continuous drainage and irrigation of the cavity with antibiotic soluti...
Eloesser flap is a single-stage procedure for the treatment of severe pleural empyema, and involves a U-shaped incision and the resection of a number of subjacent posterolateral ribs. The U-shaped flap is then folded into the pleural space creating a permanent communication. Unlike the Clagett...
Ovarian transposition is a surgical procedure in which the ovaries are displaced from the pelvis before pelvic radiation therapy in order to protect them from radiation injury. It is performed in premenopausal women with a variety of pelvic malignancies (e.g cervical cancer, rectal cancer, and ...
CT guided thoracic biopsy
CT guided thoracic biopsy is usually performed for the diagnosis of suspicious lung, pleural or mediastinal lesions. It can be performed as an outpatient procedure where patient monitoring and complications support are available. A small percentage of lung and pleural biopsies may be performed ...

Inferior vena cava filter
Inferior vena cava filter, or just IVC filter, is an endovascular device which is typically placed in the infrarenal inferior vena cava (IVC) to prevent pulmonary embolism in selected patients. This procedure is most often performed by interventional radiologists under fluoroscopic guidance. In...
Pneumonectomy is a radical lung surgery involving complete surgical removal of the lung. It is most commonly performed for a primary lung malignancy. The lung is removed in its entirety providing the patient has adequate pulmonary reserve from the contralateral lung. Recognized post-pneumonecto...
Central venous catheter
Central venous catheters (CVC) or lines (CVL) refer to a wide range of central venous access devices but can broadly be divided into four categories. They may be inserted by medical, surgical, anesthetic/ITU, or radiology specialists. Classification peripherally inserted central catheters (PIC...
Voiding cystourethrography (VCUG), also known as a micturating cystourethrography (MCU), is a fluoroscopic study of the lower urinary tract in which contrast is introduced into the bladder via a catheter. The purpose of the examination is to assess the bladder, urethra, postoperative anatomy an...
Intravenous urography (IVU), also referred to as intravenous pyelography (IVP) or excretory urography (EU), is a radiographic study of the renal parenchyma, pelvicalyceal system, ureters and the urinary bladder. This exam has been largely replaced by CT urography. Terminology Some prefer the ...
Fluoroscopic nasojejunal tube insertion
Fluoroscopic nasojejunal (NJT) or nasogastric tube (NGT) insertion is a valuable procedure offered by radiologists in patient care. The majority of nasogastric tubes are inserted on the ward level and nasojejunal tubes may be placed in theater at the time of surgery. In difficult cases, inserti...
Breast core biopsy
The percutaneous breast biopsy is one of the current choices for focal histopathological assessment of breast lesions. In contrast to fine needle aspiration, during a core needle biopsy, a hollow needle is used to withdraw small cores of tissue from the area of interest in the breast. This pro...
Thoracentesis, commonly known as a pleural tap or chest tap, is a procedure where excess pleural fluid is drained from the pleural space for diagnostic and/or therapeutic reasons. Ultrasound-guided thoracentesis performed by radiologists has been shown to have fewer complications than blind thor...
Bentall procedure is performed for the repair of ascending aortic root lesions. Typically the native aortic root and aortic valve are replaced with a composite graft that comprises both ascending aortic and aortic valve grafts, to which the coronary arteries are anastomosed. History and etymolo...
Cholecystectomies are one of the most common surgical procedures performed. Evidence of a cholecystectomy is often seen on imaging procedures with surgical clips in the gallbladder fossa and radiologists should be aware of possible complications. Indications cholelithiasis cholecystitis gal...
Normal esophageal contours on barium swallow
There are a number of normal esophageal contours or impressions that are encountered when performing a barium swallow. It is important to be able to differentiate normal contours and their variants, as well as contours that may indicate disease. Below is a list of anatomical structures that may ...
Water siphon test
The water siphon test may be performed as part of a barium swallow to assess for gastro-esophageal reflux. It is performed in the supine RPO position with the patient drinking water continuously. The test is said to be positive if there is visible barium reflux in the esophagus, and is more sens...
A lung decortication is a cardiothoracic surgical procedure usually performed for situations such as a chronic thoracic empyema or a chronic hemothorax where a diseased, often chronically infected, pleura is debrided from the adjacent lung and removed. It is also sometimes performed in selected ...
