Blunt abdominal aortic trauma is a rare but potentially lethal event. It is commonly associated with high-speed motor vehicle
accidents. Intimal flap, thrombosis, and pseudoaneurysm of the abdominal aorta are the more common findings. We present a
case of blunt abdominal aortic trauma in which CT disclosed free aortic rupture with intraabdominal bleeding and a huge retroperitoneal
hematoma, an extremely rare finding among patients reaching the hospital alive, due to its high and immediate mortality rate. 相似文献

We present the case of an 18-year-old man involved in a fall with blunt abdominal trauma. The patient had hypovolemic shock and findings of an acute abdomen. Initial computed tomography (CT) showed pulmonary contusion, pneumohemothorax, hemoperitoneum, hepatic contusion, right kidney laceration and vascular avulsion, rupture of the mesenteric vein, rupture of the right rectus muscle with bowel hernia, and infrarenal aortic dissection. There were no signs of limb or medullar ischemia. After hemodynamic stabilization and surgical repair of the associated lesions, the dissection was successfully treated with a self-expanding aortic Wallstent. Postprocedure CT showed a well-positioned patent stent and the patient was discharged asymptomatic. Percutaneous endovascular stent implantation is minimally invasive and seems to be a safe treatment for traumatic dissection of the abdominal aorta. 相似文献

The authors report on an fatal case of closed trauma of the pancreas in a context of violence. A 55-year-old man was found
unconscious on the sidewalk and died a short time after being taken to the hospital. He had been hit with several punches
to the face and abdomen 6 h before. The post-mortem examination showed numerous bruises over the whole body, a haemoperitoneum,
a fissuration of the spleen and a massive peripancreatic haemorrhage associated with a complete dilaceration of the pancreas
head. Histological examination of the pancreas revealed a massive necrosis associated with a subtotal disappearance of the
acini, numerous sites of cytosteatonecrosis and a large haemorrhagic suffusion of the peripancreatic tissue. This case illustrates
the possibilities of pancreatic injuries induced by blunt force aimed at the abdomen in a context of violence. Even if this
occurs as an isolated injury it can result in rapid death because of the particular type of pancreatic fracture which is frequently
involved. In post-mortem situations, the pancreas should be systematically checked at necropsy and a histological examination
should be carried out at the slightest doubt of a pancreatic lesion or suspicion of blunt force abdominal injuries.

Atherosclerotic abdominal aortic aneurysms typically present either asymptomatically or with abdominal or back pain. Inflammatory,
mycotic, and traumatic aortic aneurysms and aneurysms complicated by venous fistula are less common. The different clinical
presentations of these latter aneurysms should raise a suspicion to their diagnosis and appropriate preoperative evaluation.
The radiographic and clinical features of inflammatory, mycotic, traumatic, and complicated atherosclerotic aneurysms are
presented and discussed. 相似文献

Injury to the abdominal aorta secondary to blunt abdominal trauma is rare; less than 50 cases have been reported in the literature. This patient failed to demonstrate any of the classic acute signs or symptoms specific to the aortic injury, thus emphasizing the importance of a high index of suspicion in patients with the appropriate mechanism and location of injury and associated signs and symptoms. 相似文献

Purpose
To analyze the hazard and causes of death after endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms during a complete ten year follow-up.Methods
This is a retrospective clinical study of 130 consecutive patients undergoing EVAR between 1995 and 1998. One-hundred twenty-one patients (93.1%) were treated with first-generation stentgrafts and nine patients (6.9%) received second-generation devices. All patients completed a follow-up of at least 10 years, unless death occurred before then. Time and causes of death were provided by the Austrian central register of deaths.Results
The median follow-up was 7.6 years, and the 130 patients had 968.5 person-years of follow-up. The ten-year mortality rate was 62.3%. Cardiovascular events were the most frequent causes of death, with a 3.9 incidence rate per 100 person-years. Cancer death and death due to other causes occurred in 2.1 and 1.8 cases per 100 person-years, respectively. Lethal late aneurysm rupture happened in 4.6% (n = 6), which corresponds to an annual incidence rate of 0.6 per 100 person-years. All of those patients had been treated with first-generation devices.Conclusions
Cardiovascular events were the most frequent cause of death after EVAR, followed by malignancy and other diseases. The risk of dying from secondary rupture was clearly lower than that of death due to other reasons during ten years after EVAR, even in patients with first-generation stentgrafts. 相似文献13.

Objective
The maximal diameter of an abdominal aortic aneurysm (AAA) and the change in diameter over time reflect rupture risk and are used for surgical planning. However, evidence has emerged that aneurysm volume may be a better indicator of AAA remodeling. The purpose of this study was to assess the relationship between the volume and maximal diameter of the abdominal aorta in patients with untreated infrarenal AAA.Materials and methods
This was a retrospective study of 100 patients with infrarenal AAA who were followed for more than 6 months. We examined 2 sets of computed tomography images for each patient, acquired ≥6 months apart. The maximal diameter and volume of the infrarenal abdominal aorta were determined by semiautomated segmentation software.Results
At baseline, mean maximal infrarenal diameter was 5.1 ± 1.0 cm and mean aortic volume was 139 ± 72 mL. There was good correlation between the maximal diameter and aortic volume at baseline (r2 = 0.55; P < 0.001). The mean change in maximal diameter between studies was 0.2 ± 0.3 cm and the mean volume change was 19 ± 19 mL. However, the correlation between diameter change and volume change was modest (r2 = 0.34; P = 0.001). Most patients (n = 64) had no measurable change in maximal diameter between studies (≤2 mm), but the change in volume was found to vary widely (−2 to 69 mL).Conclusion
In patients with untreated infrarenal AAA, a change in aortic volume can occur in the absence of a significant change in maximal diameter. Additional work is needed to examine the relationship between change in AAA volume and outcomes in this patient group. 相似文献14.

Thoracic aortic injury (TAI) in children secondary to blunt chest trauma is rare and less well documented than TAI in adults.
To further establishe the incidence and radiographic manifestations of this severe injury, we reviewed our experimence with
TAI in children over an 8-year period.
We performed a computer search from the Trauma Registry at our level I trauma center for all cases of TAI among patients 16
years of age or younger who were admitted after sustaining blunt chest trauma between August 1984 and September 1992. We reviewed
our records of all thoracic aortograms performed on children for blunt trauma during this same time period. Indication for
angiography was determined by review of chest radiographs and medical records of all patients who underwent thoracic aortography.
We reviewed medical records and all available chest radiographs, computed tomography (CT) examinations, and thoracic aortograms
of children diagnosed with TAI.
Of 308 children admitted with blunt chest trauma, 26 (8.4%) underwent angiography to exclude aortic or great vessel injury.
Of these 26 patients, three (11.5%) were diagnosed with TAI, and one patient demonstrated a traumatic pseudoaneurysm of the
proximal left subclavian artery. The incidence of TAI among children who sustained blunt chest trauma was 1.0% in our series.
All three patients with TAI in our series were male, ages 10–12 (mean: 11 years). Chest radiographs on two of the patients
with TAI revealed mediastinal widening, ill-defined aortic outline, shift of the trachea and nasogastric tube, and depression
of the left main stem bronchus. The chest radiograph in one patient with TAI was technically inadequate. CT demonstrated abnormalities
in two patients. Angiographic findings were similar to those seen in adults.
TAI in children is rare, occurring in 1% of children sustaining blunt chest trauma in our series. Our findings support previous
reports that the plain film, CT, and angiographic findings with this injury resemble those found in adults. 相似文献

Each year, 1.4 million people in the United States are infected with Salmonella (Beneson et al. [23] Am J Med, 110:60–63, 2001). The most common clinical presentation of Salmonella infection is gastroenteritis which is usually self-limited, lasting between one to four days (Black et al. [24] N Engl J Med, 261:811–816, 1960). Although most infections are mild-to-moderate, serious disease, and death does occur (Voetsch
et al. [25] CID, 38:S127–S132, 2004). A rare but increasing number of patients present with Salmonellosis spondylodiscitis resulting
from contiguous spread of infection from the adjacent abdominal aorta. Concurrent infection of these structures exacerbates
morbidity, necessitating an elevated clinical suspicion in patients with appropriate risk factors, clinical signs and symptoms.
Furthermore, an overall mortality rate of 67% makes mycotic abdominal aortic aneurysms highly lethal (Gonda et al. [26] Radiology, 168:343–346, 1988). Thus, early diagnosis is crucial, allowing for prompt antibiotic and surgical management.
Laboratory and imaging tests obtained at the initial suspicion for infection of the spine and aorta facilitates diagnosis
while minimizing or preventing more serious complications like paresis and aortic rupture. We present a patient with a mycotic
abdominal aortic aneurysm infected with Salmonella enteritides that spread to the adjacent lumbar vertebra and left psoas muscle. 相似文献

We report an autopsy case of bronchial asthma patient with a specific abdominal aortic aneurysm. The aneurysm did not show arteriosclerosis, and a specific saccular morphology was noted above the bifurcation. Histologically, necrosis of the media resembling acute aortic dissociation was observed. However, angiitis was ruled out. In addition, the aneurysm showed a cicatrized, old intimal crack in addition to the rupture site, suggesting repeated failures. The long-term steroid therapy-related fragility of the arterial wall may have been involved in the etiology of the aneurysm. 相似文献

In this article we present a fatal case of a ruptured intercostal artery pseudoaneurysm that occurred a number of years after
an incident in which the patient suffered a blunt-trauma injury. A long interval between blunt trauma and this type of fatality
has rarely been reported. This case discusses a 49-year-old woman who was found dead at her home by her husband and was referred
for autopsy because the cause of death was uncertain. Her past medical history was unknown; however, it was learned that she
had a bicycle accident 4 years previously and had sustained injuries to the left side of her body. During the autopsy, healed
fractures in the bones of the left lower rib cage and a large amount of blood in the left thorax were observed. Furthermore,
a hematoma, containing a small rupture was found in the left tenth intercostal space adjacent to the thoracic vertebrae. Histological
examinations showed that the wall of the left tenth intercostal artery was ruptured, with recent blood clots including fibrin.
Additionally, in the lesion where the tunica adventitia was disrupted, the dissecting cavity was filled with blood. We concluded
that the woman died of hemorrhagic shock resulting from a ruptured intercostal artery pseudoaneurysm that formed as a result
of the injury incurred from the bicycle accident 4 years before. 相似文献
