â) was preferentially used. There was no operative mortality or paraplegia. One patient had a transient leg monoparesis that reverted completely. No patient had type I endoleaks. Two patients had type II endoleaks on discharge, that sealed spontaneously. In a follow up, ranging from 2 to 17 months, one patient died of a bronchopneumonia and no aneurysm rupture has been detected. Conclusions: The short term results of endoluminal treatment of thoracic aorta aneurysms are excellent. This treatment is less invasive and has less complications than conventional surgery (Rev Méd Chile 2003; 131: 617-22)]]>
IntroducciónEl síndrome compartamental constituye una urgencia médica, ya que al no ser tratada oportunamente, habitualmente conduce a secuelas neurológicas, amputaciones, insuficiencia renal o muerte. Traumatismos, hemorragias postoperatorias, edema post-reperfusión de isquemia arterial severa o prolongada, entre otros, generan un aumento patológico de la presión de los tejidos contenidos en un compartimento anatómico inexpansible limitado por estructuras óseas y aponeurosis musculares, más frecuentemente en las extremidades inferiores. El aumento progresivo de la presión intracompartamental es responsable de lesiones por compresión de nervios, venas, arterias y fibras musculares, que son responsables de las manifestaciones clínicas que aparecen progresivamente: dolor muy intenso, desproporcionado y progresivo, déficit neurológico sensitivo y luego motor de la extremidad, gran tensión y sensibilidad a la palpación de los compartimentos afectados e isquemia con pérdida de pulsos en casos avanzados 1 .El tratamiento fundamental es descomprimir los compartimentos por medio de fasciotomías. Éstas deben ser amplias, involucrar la totalidad de los compartimentos amenazados y precoces (su postergación determina secuelas irreversibles o amenaza de la viabilidad de la extremidad). Una vez abierta la piel y aponeurosis, es esperable la herniación de los distintos músculos descomprimiendo los compartimentos.Más de un tercio de los pacientes con fasciotomía presentan complicaciones, la más frecuente y temida es la infección, pudiendo ser determinante en el destino final de la extremidad 2-4 . Contribuyen al desarrollo de infección: la prolongada y amplia exposición de partes blandas favorecida por la retracción progresiva de los bordes cutáneos, la presencia de músculo isquémico o necrótico, y que la indicación de fasciotomía haya sido de origen vascular y en las extremidades inferiores 2 .El manejo habitual de las heridas asociadas a fasciotomías requiere de injertos dermo-epidérmi-cos, colgajos fascio-cutáneos y/o el cierre por segunda intención. Una alternativa de manejo, descrita por Harris en 1993 5 y complementada por Berman en 1994 6 , es la denominada "shoelace technique" por su semejanza con la disposición de los cordones en los zapatos. Dado que esta técnica pareciera no ser conocida en nuestro medio, me parece interesante comunicarla para difusión a la comunidad quirúrgica local.
Vessel loops for primary closure of fasciotomies Background: Compartment syndrome of the extremity may occur after severe trauma with vascular lesions secondary to fractures, crushes or gunshots. To prevent it a fasciotomy must be done. Aim To report the use vessel loop shoelace technique for the progressive closure of the fasciotomy. Material and methods: Descriptive study of 24 patients aged 26 ± 9 years (21 males) that required fasciotomy to prevent compartment syndromes. The fasciotomy wound was closed progressively using vessel loops anchored to the skin with staples or sutures, which were tightened progressively, according to the evolution. Results: The studied patients required a total of 56 fasciotomies. In all patients a complete or near complete closure of the wound was achieved. The mean closure time was 9.5 ± 3.3 days. Mean hospital stay was 12.3 ± 4.3 days. Conclusions: Vessel loop shoelace technique is effective for fasciotomy wound closure.
Carotid body tumors: Report of ten cases Background: Carotid body tumors arise from a cellular conglomerate located at the carotid bifurcation. Progressive enlargement can involve the arterial wall and neighbor cranial nerves. Aim: To report a series of 10 patients treated of carotid body tumors and review national experience. Patients and methods: Between 1984 and 2006, we operated 8 women and 2 men, aged 19 to 75 years, with this type of tumor. Results: The most common cause for consultation was a cervical mass in 90%, with a mean evolution lapse of 13.2 months (range 3 to 126). In all cases, diagnosis was confirmed with angiographic imaging and histopathology. Ten tumors were surgically removed with no complications. Eighty percent of tumors were in stage II according to Shamblin classification. During long term follow up all patients have remained asymptomatic. Only 31 carotid body tumors have been reported in Chilean medical literature during a 43 year period. Conclusions: Paragangliomas of the carotid body can be diagnosed in clinical grounds, requiring vascular imaging. These infrequent lesions are generally benign, early surgical removal by surgeons with vascular expertise avoids neurological and or vascular complications
Endovascular surgery allows effective exclusion of AAA avoiding progressive enlargement and/or rupture and is a good alternative to open repair. Close and frequent postoperative follow up is mandatory.
Background: Dissections that involve the ascending aorta are classified as type A, regardless of the site of the primary intimal tear, and all other dissections as (Rev Méd Chile 2008; 136: 1431-8).
Hybrid treatment aberrant right subclavian artery Introduction: An aberrant right subclavian artery is the most frequent aortic arch malformation. It is frequently an incidental finding of imaging studies and serious complications may arise if left untreated. Clinical case: We present a case of a young woman with a dilated aberrant right subclavian artery that was successfully treated by a hybrid approach.
Surgical treatment of thoracoabdominal aneurysms is a big technical challenge with a high rate of complications and mortality. It requires a large exposure and transient interruption of vital organ perfusion during its repair. Endovascular repair is a less invasive alternative available over the last decade. We report four male patients aged 44 to 76 years, with thoracic aortic aneurysms and involvement of visceral aorta, treated with a two stage procedure. During the first stage, a retrograde revascularization of the superior mesenteric and renal arteries from the infrarenal aorta was done, associated in two cases to a concomitant repair of an infrarenal aortic aneurysm. In the second stage, an endovascular graft was placed through the femoral artery, from the segment proximal to the aneurysm to the infrarenal aorta, above the origin of the visceral artery reconstructions, excluding the aneurysm from circulation. In one patient, both stages were concomitant and in three the second stage was delayed. One patient presented a postoperative bleeding that required reintervention without adverse consequences. No patient died, presented paraplegia or deterioration of renal function. After follow up of 6 to 20 months, there is no evidence of aneurysm growth or complications derived from the procedure.
