Insights

Three-dimensional (3D) venography can identify effective intrahepatic veno-venous shunts (vv-shunts), potentially avoiding invasive procedures during liver surgery. This imaging technique aids in detecting crucial vascular connections for safe hepatectomy.

Area of Science:

  • Medical Imaging
  • Vascular Surgery
  • Hepatobiliary Surgery

Background:

  • Hepatic vein (HV) resection during hepatectomy requires confirmation of an effective intrahepatic veno-venous shunt (vv-shunt).
  • Traditional methods for shunt assessment can be invasive.

Purpose of the Study:

  • To evaluate the efficacy of three-dimensional (3D) venography, reconstructed from multidetector-row computed tomography (MDCT) during angiography, in detecting vv-shunts.
  • To determine if visualized vv-shunts are clinically significant for hepatectomy planning.

Main Methods:

  • Reconstruction of 3D venography using computer software.
  • Analysis of 88 patients with intrahepatic tumors undergoing MDCT angiography.

Main Results:

  • A clinically efficient vv-shunt was identified in 14.8% of patients (13 out of 88).
  • Specific shunts identified include right hepatic vein (RHV)-middle hepatic vein (MHV) and RHV-inferior right hepatic vein (IRHV).
  • One case demonstrated successful preservation of an RHV-IRHV shunt, preventing post-surgical congestion after extensive liver resection for hepatocellular carcinoma (HCC).

Conclusions:

  • Despite a low detection rate, 3D venography effectively visualizes functionally significant vv-shunts.
  • The presence of a visualized vv-shunt on 3D venography can obviate the need for invasive occlusion venography.
  • This imaging modality enhances surgical planning for hepatectomy, particularly when HV resection is considered.

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
