Inferior Vena Cava Compression Caused by a Retroperitoneal Hematoma Following an Abdominal Aortic Aneurysm Rupture
1Department of Cardiovascular Surgery, Tsukuba Medical Center Hospital, Tsukuba, Ibaraki, Japan.
Abstract:
This report presents the case of a 43-year-old man with inferior vena cava (IVC) compression caused by a retroperitoneal hematoma following an abdominal aortic aneurysm (AAA) rupture. Preoperative computed tomography scans revealed an infrarenal AAA with a retroperitoneal hematoma nearly occluding the IVC. After emergency aortic grafting, IVC thrombosis, deep venous thrombosis (DVT), and pulmonary thromboembolism (PTE) arose. Anticoagulation therapy resolved these thrombotic complications. Disappearance of the hematoma and IVC recanalization were confirmed 3 months postoperatively. Although IVC compression caused by a retroperitoneal hematoma is temporary, careful attention should be paid to IVC thrombosis, DVT, and PTE as possible complications.

Ultrasound I: Abdominal Ultrasonography
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...
