The surgical treatment of traumatic neck injuries in patients with hostile anatomy is associated with higher risk of complications, due to the technical challenge and associated clinical conditions. The use of a percutaneous closure device for removal of a 7.5 Fr sheath, nonintentionally implanted into the carotid artery, is reported. The right common carotid sheath was removed after introducing a 0.035-inch guidewire; the Angioseal 8 Fr device was then introduced over the wire, successfully sealing the puncture site. Duplex scan control showed patency of the carotids, sealing of the puncture, and adequate flow in the jugular vein and carotid arteries. This maneuver allowed the safe placement of a percutaneous arterial device (Angioseal) to close the puncture site.

Abstract Non-dialytic chronic renal failure is a contraindication related tothe endovascular treatment of abdominal aortic aneurysms. The useof alternative contrast agents, such as gadolinium, provides good-quality images and is associated with nephrotoxicity. We report a caseof endovascular treatment of an abdominal aortic aneurysm guidedby color-flow Doppler ultrasonography. An 82-year-old male patient,with abdominal aortic aneurysm (55 mm in diameter) and creatinineclearance of 17 ml/min, underwent implantation of modular bifurcatedaortic stent-graft, using that imaging method associated withradioscopy. Iodinated contrast was not used. The immediate resultand 1- and 6-month controls showed complete aneurysm exclusion.Renal function is still unaltered. We conclude that the stent-graftimplantation guided by color-flow Doppler ultrasonography inpatients with nonterminal chronic renal failure and with favorableanatomy is a feasible and safe method.Keywords: Endovascular treatment, abdominal aortic aneurysm,renal failure, color-flow Doppler ultrasonography, duplex scan.

Occlusion of the iliac arteries is a common disease. Several surgical options are available to treat them, such as aorto-bifemoral bypass graft, cross femoro-femoral bypass, endoprosthesis implants and others. Aorto-bifemoral bypass graft is considered the treatment that provides the best results. Endovascular treatment for occlusion of the iliac arteries provides high success rates and low incidence of complications. Twenty-four patients, aged between 39 and 82 years (mean 61 years), were submitted to this treatment. Intermittent claudication and critical ischemia were the indications in 19 and 5 patients, respectively. The most common risk factor was smoking (19 patients). The technical success rate of iliac artery recanalization was 91.7% and the patency rate after one year was 71%. The good results achieved with percutaneous recanalization and stenting of occluded iliac arteries, which presents low morbidity and mortality rates, suggest that this procedure should be included among the therapeutic options for the treatment of iliac arteries occlusion.

Angioplastia subintimal sem o uso de stent em paciente diabético portador de lesão complexa no pé

Diabetic patients presenting with both peripheral vascular disease and complex soft-tissue defects are often treated by primary amputation. We report the case of a 66-year-old female patient with multiple comorbid conditions. She presented left foot plantar abscess and TASC C superficial femoral lesion. Endovascular revascularization of the left lower limb was performed employing the subintimal angioplasty technique, without stenting or endografting. This combined approach of lower limb revascularization associated with intensive care in diabetic foot wounds should always be considered before amputation. We recommend subintimal angioplasty as an option for high-risk patients with complex limb wounds.

El tratamiento quirurgico de las lesiones traumaticas del cuello en los pacientes con una anatomia dificil esta asociado con un riesgo elevado de complicaciones debido al desafio tecnico y a los procesos clinicos asociados. Se describe el uso de un dispositivo de cierre percutaneo para la retirada de un introductor 7,5 Fr, implantado de forma inadvertida en la arteria carotida. El introductor situado en la carotida comun derecha se retiro tras introducir una guia de 0,035 pulgadas; posteriormente se introdujo el dispositivo Angioseal 8 Fr sobre la guia sellando de forma satisfactoria la zona perforada. Un eco-Doppler de control mostro la permeabilidad de las carotidas, el sellado de la perforacion, y el flujo adecuado en la vena yugular y las arterias carotidas. Esta maniobra permitio colocar de forma segura un dispositivo arterial percutaneo (Angioseal) para cerrar el lugar perforado.
