Arterial bleeding in pelvic trauma: priorities in angiographic embolization.

Vascular injuries are a major source of morbidity and mortality in patients with blunt pelvic trauma. Up to 40% of patients with pelvic fractures related to blunt traumatic injury experience intra-abdominal or intrapelvic bleeding, which is the major determining factor of mortality. Sources of hemorrhage within the pelvis include injuries to major pelvic arterial and venous structures and vascular damage related to osseous fractures.

Using color power Doppler ultrasound imaging to diagnose the acute scrotum. A pictorial essay.

Acute nontraumatic scrotum represents one of the most important emergencies in the male population. Etiology of the acute scrotum greatly varies, but the most common causes include testicular torsion and inflammatory disease. Currently, the most successful diagnostic imaging is ultrasound integrated by the application of color power Doppler.

Collagen-only biomatrix as a novel dural substitute. Examination of the efficacy, safety and outcome: clinical experience on a series of 208 patients.

Objectives: Dural replacement materials and other measures can provide an effective barrier between the subarachnoid compartment and the extradural space when a watertight closure of the patient's own dura is not possible.

Patients And Methods: We evaluated the efficacy and safety of a novel collagen-derived dural substitute on a series of 208 patients undergoing a variety of neurosurgical procedures.

Results: No patients experienced any local or systemic complications nor toxicity related to the dural patch.

Multi-detector row computed tomography and blunt chest trauma.

Blunt chest trauma is a significant source of morbidity and mortality in industrialized countries. The clinical presentation of trauma patients varies widely from one individual to another and ranges from minor reports of pain to shock. Knowledge of the mechanism of injury, the time of injury, estimates of motor vehicle accident velocity and deceleration, and evidence of associated injury to other systems are all salient features to provide for an adequate assessment of chest trauma.

Pneumoretroperitoneum Associated with "Dirty Mass": An Unusual Case of Rectal Perforation.

Perforation of the rectum requires early recognition and treatment. The diagnosis of rectal perforation is sometimes difficult owing to non specific clinical presentation, especially in elderly patients, in whom, in case of acute abdomen, Computed Tomography (CT) is increasing used as first diagnostic procedure [1]. Several CT signs of gastrointestinal perforation have been described [2, 3].

Acute tracheobronchial injuries: Impact of imaging on diagnosis and management implications.

Purpose: To evaluate the role of chest radiography, single-slice CT and 16-row MDCT in the direct evidence of tracheobronchial injuries.

Methods: Patients with acute tracheobronchial injury were identified from the registry of our level 1 trauma center during a 5-year period ending July 2005. Findings at chest radiograph and CT were compared to those shown at bronchoscopy.

Color power Doppler US and contrast-enhanced US features of abdominal solid organ injuries.

Utilization of color power Doppler and sonographic contrast agents to basic ultrasound (US) further improve the detection and characterization of abdominal injuries, increasing the diagnostic accuracy and value of US as an important technique in the evaluation of the abdominal trauma. This paper provides an illustrated summary of our clinical experience with color power Doppler US (CD-US) and contrast-enhanced US (CE-US) in the evaluation of abdominal solid organ injuries, involving 32 documented cases over a 2-year period. The findings of the CD-US and CE-US were compared with those provided by state-of-the-art contrast-enhanced multidetector 16-row CT.

Determining optimum management of descending necrotizing mediastinitis with CT; experience with 32 cases.

To determine the value of helical computed tomography (CT) in the diagnosis, management and outcome of patients suspected of having descending necrotizing mediastinitis (DNM). Thirty-two patients with suspected DNM were submitted to contrast-enhanced single detector-row helical CT, four detector-row CT and 16 detector-row CT of the neck and chest. In 10/32 patients (group 1) no abnormality was observed in the neck or in the chest spaces on CT scan.
