Cect abdomen full form

This is a basic article for medical students and other non-radiologists CT abdomen is an increasingly common investigation that is used to help make diagnoses of a broad range of pathologies. A CT abdomen in its simplest form is a CT from diaphragm to symphysis pubis performed 60 seconds after pump-injection of iodinated contrast into a peripheral vein. However, depending on the clinical question, a variety of different protocols can be used.

• Original Article • 18 August 2022 Contrast-enhanced computed tomography abdomen versus diagnostic laparoscopy-based management in patients with penetrating abdominal trauma: a randomised controlled trial • • • • • • • • • • • • • • • … • ORCID: orcid.org/0000-0001-8434-9629 Show authors European Journal of Trauma and Emergency Surgery volume 49, pages 1–10 ( 2023) Purpose Penetrating abdominal trauma was traditionally managed by mandatory exploration, which led to high rates of non-therapeutic surgery and prolonged hospital stay. Diagnostic laparoscopy (DL) is a less-invasive alternative; however, it requires general anaesthesia and carries a potential risk of iatrogenic injuries. Contrast-enhanced computed tomography (CECT)-guided selective non-operative management (SNOM) may avoid surgery altogether, but there is apprehension of missed injury. Randomised trials comparing these two modalities are lacking. This study is aimed at comparing outcomes of these two management approaches. Methods Hemodynamically stable patients with penetrating trauma to anterior abdominal wall were randomised in 1:1 ratio to DL or CECT-based management. Primary outcome was length of hospital stay (LOS). Secondary outcomes were rate of non-therapeutic surgery, complications, and length of intensive care unit (ICU) stay. Results There were 52 patients in DL group and 54 patients in CECT group. Mean LOS was comparable (3 vs 3.5 days; p = 0.423). Rate of non-therapeutic surgery was significantly ...

Background Portomesenteric Vein Thrombosis (PMVT) following Laparoscopic Sleeve Gastrectomy (LSG) is an uncommon but potentially debilitating complication. Catheter-Directed Thrombolysis (CDT) has an evolving role in recanalizing the venous flow and preventing thrombus propagation. Therefore, it can be used as an alternative or in combination with systemic anticoagulants in selected patients. We report two trans-hepatic and trans-splenic CDT. The patient’s clinical details, radiological findings, safety, and efficacy are reported. Cases presentation Two patients presented to the Emergency Department (ED) within 14 days of surgery. The presenting complaints were generally nonspecific. The diagnosis of PMVT was established in both patients based on abdominal Contrast-Enhanced Computed Tomography (CECT). The two patients received a combined therapy of subcutaneous (SC) heparinization and CDT using a trans-hepatic approach in case 1 and a trans-splenic approach in case 2. Subsequent post-procedure venograms and CECT were performed and showed significant thrombus resolution. Both patients received oral anticoagulant therapy upon discharge with a successful overall recovery. Conclusion PMVT is an infrequent and severe post LSG complication. Various approaches for re-establishing the portal venous flow have been described according to the severity of venous thrombosis. This article describes CDT therapy as a safe and effective option for treating PMVT in symptomatic patients. ...

What is a CT scan of the abdomen? Computed tomography (CT scan or CAT scan) is a noninvasive diagnostic imaging procedure that uses a combination of In standard X-rays, a beam of energy is aimed at the body part being studied. A plate behind the body part captures the variations of the energy beam after it passes through skin, bone, muscle, and other tissue. While much information can be obtained from a standard X-ray, a lot of detail about internal organs and other structures is not available. In computed tomography, the X-ray beam moves in a circle around the body. This allows many different views of the same organ or structure. The X-ray information is sent to a computer that interprets the X-ray data and displays it in a two-dimensional (2D) form on a monitor. CT scans may be done with or without "contrast." Contrast refers to a substance taken by mouth or injected into an intravenous (IV) line that causes the particular organ or tissue under study to be seen more clearly. Contrast examinations may require you to fast for a certain period of time before the procedure. Your doctor will notify you of this prior to the procedure. CT scans of the abdomen can provide more detailed information about abdominal organs and structures than standard X-rays of the abdomen, thus providing more information related to injuries and/or diseases of the abdominal organs. CT scans of the abdomen may also be used to visualize placement of needles during biopsies of abdominal organs or tumo...
