1/29. Multivascular trauma on an adolescent. Perioperative management.Penetrating vascular injury, in particular at the neck, is a life-threatening trauma not only of the nature and the anatomic proximity of cardiovascular, aerodigestive, glandular and neurologic system but also of the development of early and late complications. The following case report describes our experience with a penetrating wound patient, who was admitted to our emergencies twelve hours after the accident. The only demonstrable objective signs included a large hematoma at the right-side of the neck and distended mediastinum on the chest X-ray. As the patient was cardiovascularly unstable he was immediately transported to the theater without any angiography. The mandatory operative exploration was initially unsuccessful and a median sternotomy with a standard cardiopulmonary bypass and deep hypothermia circulatory arrest was established to restore all the vascular lesions. Actually, the patient was in critical condition with a rupture of the right internal jugular vein, a large pseudoaneurysm of the innominate artery and an avulsion of the ascending aorta with the suspicion of a cardiac tamponade. The postoperative period lasted two full months, while complications appeared. The substantial message from this multivascular trauma is the early diagnosis of the life-threatening complications as exsanguinations, ventricular fibrillation and the ability to minimize postoperative complications, which will impair the normal functional life of the patient.- - - - - - - - - - ranking = 1keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
2/29. Traumatic pseudoaneurysm of the abdominal aorta.A traumatic pseudoaneurysm of the abdominal aorta is a rare entity, occurring as the result of a missed aortic lesion at the time of the initial injury. Therefore, clinical suspicion and careful abdominal exploration at first laparotomy is mandatory to prevent aortic pseudoaneurysm formation and its risk of delayed rupture. We present a case of successful surgical treatment of a suprarenal aortic false aneurysm, presenting 4 weeks after a life-threatening gunshot wound in a 13-year-old child.- - - - - - - - - - ranking = 6.0306501448847keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
3/29. Use of through-and-through guidewire for delivering large stent-grafts into the distal aortic arch.The availability of large diameter stent-grafts is now allowing the endovascular treatment of thoracic aortic aneurysms. Most aneurysms are closely related to the distal arch and it is thus necessary to pass the delivery systems into the arch to effectively cover the proximal neck. Even with extra-stiff guidewires in position, it may still be difficult to achieve this, as a result of tortuosity at the iliac arteries and the aorta. We detail a technique where a stiff guidewire is passed from a brachial entry point through the aorta and out at the femoral arteriotomy site. This allows extra-support and may enable the delivery system to be passed further into the aortic arch than it could with just the regular guidewire position.- - - - - - - - - - ranking = 0.061300289769342keywords = aneurysm (Clic here for more details about this article) |
4/29. rupture of a large ophthalmic segment saccular aneurysm associated with closed head injury: case report.OBJECTIVE AND IMPORTANCE: Although each year approximately 30,000 to 50,000 cases of subarachnoid hemorrhage in the united states are caused by the rupture of intracranial saccular aneurysms, there is little information in the literature documenting the association of aneurysmal rupture with closed head injury. CLINICAL PRESENTATION: A 61-year-old woman presented after a motor vehicle accident with multiple injuries, including a severe closed head injury. Computed tomography revealed a diffuse basal subarachnoid hemorrhage. angiography revealed the source as a large aneurysm arising from the ophthalmic segment of the left carotid artery. INTERVENTION: After the patient was stabilized for her multiple injuries, she underwent craniotomy and clipping of the aneurysm. She recovered without developing new neurological deficits. CONCLUSION: Although the association of head trauma and aneurysmal subarachnoid hemorrhage is rare, the presence of significant basal subarachnoid blood on a computed tomographic scan should alert the physician to the possibility of a ruptured aneurysm.- - - - - - - - - - ranking = 0.30650144884671keywords = aneurysm (Clic here for more details about this article) |
5/29. Endovascular repair of an innominate artery false aneurysm following blunt trauma.PURPOSE: To describe a case of endovascular graft exclusion of an innominate artery pseudoaneurysm arising from blunt trauma. methods AND RESULTS: A 21-year-old patient was admitted following a major road accident. Computed tomography (CT) and aortography on admission disclosed an isolated innominate artery pseudoaneurysm. The lesion was stable, so an elective endoluminal repair was undertaken once the patient was treated for his other injuries. The right carotid artery was exposed and controlled, and the aneurysm was excluded by transluminal implantation of a customized stent-graft consisting of predilated polytetrafluoroethylene graft material covering a balloon-expandable Palmaz stent. A CT scan at 1 month and duplex scans at 6-month intervals documented good stent-graft positioning and aneurysm exclusion over a period of 18 months. CONCLUSIONS: This case illustrates the potential durability of endoluminal repair of innominate artery lesions and highlights the potential role of this minimally invasive alternative to surgery in these clinical situations.- - - - - - - - - - ranking = 2.183900869308keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
6/29. Traumatic cervical distraction complicated by delayed reduction due to traumatic vertebral artery pseudo-aneurysm.A 23-year-old male involved in a high-speed collision acquired, among other injuries, a wide fracture distraction at C2/C3. Reduction was delayed by an enlarging vertebral artery pseudo-aneurysm at the site of injury which was successfully treated by proximal endovascular occlusion with a detachable polymer-filled balloon. A traumatic arachnoid cyst or pseudomeningocele was also demonstrated at the injury site but intervention was not required. The treatment and outcome of these three uncommon injuries in the literature is reviewed and discussed. Given the severity of the injury, the absence of severe long-term neurological disability is notable.- - - - - - - - - - ranking = 0.15325072442335keywords = aneurysm (Clic here for more details about this article) |
7/29. Abdominal compartment syndrome.Abdominal compartment syndrome may be defined as the deleterious pathophysiologic consequences of a significant increase in intra-abdominal pressure. These alterations can affect respiratory mechanics, cardiovascular system, regional blood flow, renal function, urine output, and intracranial pressure. Although the syndrome may be associated with many clinical situations, the most common are severe abdominal trauma and ruptured abdominal aortic aneurysm. Diagnosis depends upon recognition of the clinical syndrome followed by an objective measurement of intra-abdominal pressure, the most common being the measurement of bladder pressure. Treatment consists of adequate fluid resuscitation and surgical decompression when necessary.- - - - - - - - - - ranking = 0.030650144884671keywords = aneurysm (Clic here for more details about this article) |
8/29. Multiple sequential posttraumatic pseudoaneurysms following high-energy injuries: case report and review of the literature.A 15-year-old boy sustained severe multisystem injuries from a satchel charge while in his native village in southern lebanon. After evacuation and resuscitation measures, he had successful intensive multidisciplinary surgical care. His long-bone fractures were stabilized by tubular external fixation systems, and his lacerated right tibialis anterior artery was grafted. Twenty days after injury, he developed a pseudoaneurysm of the left distal ulnar artery, which was surgically resected and the ulnar artery proximally ligated. Two weeks later, a pseudoaneurysm of the left peroneal artery, distal to the knee and coupled with an arteriovenous fistula, was diagnosed. This was treated by fluoroscopic controlled embolization with placement of stents. The patient recovered uneventfully. He was last seen two years after surgery, and no gross vascular compromise of any of his limbs was evident. This appears to be the only reported patient with late-developing multiple posttraumatic pseudoaneurysms after severe blast and shrapnel injuries. This development suggests that late sequelae of blast injuries may be topographically widespread and can evolve months after the injury. As such, these patients should be followed closely with a high degree of suspicion for the appearance of new signs or symptoms.- - - - - - - - - - ranking = 7keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
9/29. Simultaneous surgical treatment of chronic post-traumatic aneurysm of the thoracic aorta, diaphragmatic hernia and giant emphysema bulla.Thoraco-abdominal blunt trauma can lead to multiple injuries of several organs. We report a case of a patient in whom, 10 years after a trauma, a chest X-ray showed visceral herniation into the left thorax. Angio computed tomographic scan (CTS) and magnetic resonance imaging (MRI) confirmed these lesions and also showed a saccular thoracic aortic aneurysm. During the surgical procedure a giant post-traumatic emphysema bulla of the left lower pulmonary lobe was discovered and repaired. In the presence of diaphragmatic injuries, CTS and MRI are mandatory for excluding other organ involvement, and during the surgical procedure, careful inspection of left thorax and abdomen should always be done to repair other possible injuries not seen before.- - - - - - - - - - ranking = 0.15325072442335keywords = aneurysm (Clic here for more details about this article) |
10/29. Pseudoaneurysm of the inferior gluteal artery following polytrauma: diverse presentation of a dangerous complication: a report of two cases.Gluteal artery aneurysms are rare, and the majority of them are pseudoaneurysms secondary to blunt or penetrating trauma. The superior gluteal artery is normally affected. Inferior gluteal artery pseudoaneurysms are uncommon, and review of the literature revealed only 10 cases in the last 30 years. The mainstay of diagnosis is angiography, but these aneurysms may not be visible on an aortic flush angiogram, and super selective angiography may be required to delineate the anatomy. Treatment is either by surgical therapy or minimally invasive techniques, such as embolization, during angiography. We report two cases of pseudoaneurysms of the inferior gluteal artery following pelvic and acetabular trauma, presenting very differently in time and clinical picture. A review of the relevant literature is also presented.- - - - - - - - - - ranking = 3.183900869308keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
