Transección traumática aguda de la aorta torácica: tratamiento endovascular / Endovascular treatment of acute traumatic rupture of the thoracic aorta: report of 1 case

Traumatic rupture of the aorta has a near 80 percent mortality. Most patients die on the site of the accident. Conventional surgical repair of these lesions has a high morbidity and mortality, generally associated to the severity of associated lesions. Over the last decade, endovascular treatment has become an effective therapeutic alternative. We report a 40 years old male, that suffered a traumatic rupture of the descending thoracic aorta in a car accident. A successful endovascular repair was performed, installing an endoprothesis on the site of the lesion, using a femoral artery approach. The patient had a good postoperative evolution and was discharged from the hospital once complete rehabilitation of his associated lesions was obtained

Isquemia mesentérica aguda por disección espontánea y aislada de la arteria mesentérica superior / Mesenteric ischemia caused by a spontaneous and isolated dissection of the superior mesenteric artery

Spontaneous dissection of the superior mesenteric artery is an unusual cause of mesenteric ischemia. Diagnosis can be based on findings of the helicoidal computed tomography or selective angiography of the superior mesenteric artery. We report two male patients, aged 47 and 50 years, who were admitted for abdominal pain. Isolated superior mesenteric artery dissection was confirmed by angiography. Both patients were treated with anticoagulation, conservative measures and recovered uneventfully

Pseudoaneurisma traumático de troncos supra-aórticos: tratamiento endovascular: casos clínicos / Endovascular treatment of traumatic pseudoaneurysms of aortic arch branches: report of3 cases

The traditional treatment of traumatic lesions of the aortic arch branches requires extended surgical exposures, not exempt of morbidity and mortality. Over the last decade, devices that allow a minimally invasive treatment, have been developed. The vessel can be repaired without direct exposure, using an endovascular procedure. We report three patients with traumatic pseudoaneurysms of the left subclavian, brachiocephalic and left common carotid arteries, respectively. All lesions were successfully repaired with the insertion of an endograft. Although long term results of these procedure are unknown, repair of a future stenosis or occlusion is less complicated than the treatment required by the original lesion. Endoluminal repair appears as a safe, efficient and less invasive treatment for these lesions

Aneurisma roto de aorta torácica descendente: tratamiento endovascular / Endovascular treatment of a ruptured thoracic aorta aneurysm

In 1991, a technique to exclude aortic aneurysms from circulation inserting an endoluminal graft through the femoral artery, was described. This procedure, usually used for elective abdominal aneurysms, can also be used in the thoracic aorta. We report a 41 years old male with a Marfan syndrome, presenting with a descending aorta aneurysm that ruptured to the mediastinum and pleural cavity. He was compensated hemodynamically and an endovascular stent-graft was deployed at the ruptured zone, through the femoral artery. The postoperative evolution of the patient was uneventful. This technique will allow a less invasive treatment of ruptured aortic aneurysms

Terapia endovascular en el síndrome de vena cava superior: caso clínico / Endovascular treatment of superior vena cava syndrome: report of 1 case

The treatment of superior vena cava syndrome is usually oriented to the underlying cause, that can be too slow in emergency cases. We report a 49 years old woman with a multiple myeloma that was admitted due to a superior vena cava syndrome caused by a central venous catheter used for chemotherapy for 20 weeks. She was successfully treated with thrombolysis, angioplasty and stent placement. The patient died 7 months later due to the underlying disease. Long term catheters are the responsible for 20 to 30 percent of superior vena cava syndromes. Endovascular treatment of the syndrome is successful in 60 to 100 percent of cases with a symptomatic relapse in 4 to 45 percent of patients
