Spontaneous soft tissue hematomas

Abstract

Spontaneous muscle hematomas are a common and serious complication of anticoagulant treatment. The incidence of this event has increased along with the rise in the number of patients receiving anticoagulants. Radiological management is both diagnostic and interventional. Computed tomography angiography (CTA) is the main tool for the detection of hemorrhage to obtain a positive, topographic diagnosis and determine the severity. Detection of an active leak of contrast material during the arterial or venous phase is an indication for the use of arterial embolization. In addition, the interventional radiological procedure can be planned with CTA. Arterial embolization of the pedicles that are the source of the bleeding is an effective technique. The rate of technical and clinical success is 90% and 86%, respectively.

“…4), where bleeding may arise from the epigastric vessels; internal thoracic, lateral thoracic or thoracodorsal vessels; and lumbar vessels, respectively. (11,12) Other less common sites of involvement include the gluteal regions and extremities, where haematomas may lie within the muscular compartments or subcutaneous soft tissue ( Fig. 5).…”

“…• subarachnoid hemorrhages and intracranial aneurysms [1][2][3]; • multiple injuries -damage to the aorta and its branches [4][5][6][7]; • gastrointestinal hemorrhage both from arterial causes and from portal hypertension [8,9]; • rupture of aneurysms of visceral branches of the aorta [10]; • the specific treatment of postoperative or postinterventional radiology and soft tissue oncology bleeding [11][12][13][14]; • hemoptysis and epistaxis [15,16].…”

Coagulopathy-related soft tissue hematoma: a comparison between computed tomography findings and clinical severity

“…Among the various etiologies, hemorrhage due to anticoagulation or bleeding diatheses typically presents as soft-tissue hematoma (1,2). With the aging population and the increased use of anticoagulation treatments, the incidence of coagulopathy-related soft-tissue hematoma (CRSH) has been increasing annually (3).…”

“…Although several studies have recently reported the efficacy of transarterial embolization (TAE) for CRSH (3,(8)(9)(10)(11)(12)(13)(14)(15)(16)(17), the correlation between CT findings and clinical outcomes remain unclear. The aim of the present study was to characterize patients with CRSH by comparison of the morphological features on CT and clinical severity, to aid physicians in therapeutic decisions.…”
