Abstract:
Paracentesis is a common procedure used in the diagnostic evaluation of peritoneal fluid as well as the therapeutic removal of high-volume ascites. Although generally regarded as a safe procedure, complications may arise from arterial injury, including hematomas and pseudoaneurysms. Transcatheter embolization and surgery are first-line interventions for injuries refractory to conservative management. We present a case where a patient failed conventional therapies for hemoperitoneum following a paracentesis which resolved after thrombin injection into the subcutaneous tissues, a novel use for thrombin. Using a linear 12-3 MHz transducer, approximately 3000-3500 U of thrombin was injected through connecting tubing and a 25-gauge needle by the interventional radiologist into the subcutaneous tissues around the origin of the arterial hemorrhage. The bleeding ceased and the patient's hemoglobin and hemodynamics stabilized.

Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
