Use of autologous superficial femoral artery in surgery for aortic prosthesis infection.

The surgical management of aortic prosthesis infection remains an enormous challenge for the vascular surgeon and a critical issue for the patient's well-being and life. Several techniques for its management have been devised and employed over the years, but none of them has been totally satisfactory. Thus new alternatives are needed. We present the clinical case of an infected aortic prosthesis in a 41-year-old man that was complicated by duodenal and ureteral erosion. The autologous superficial femoral artery was used successfully in the treatment of this most demanding situation.

A new approach for the surgical management of unilateral iliac artery occlusive disease: the iliofemoral crossover transposition.

Aortobifemoral bypass remains the standard therapy for aortoiliac occlusive disease. Extraanatomic revascularization has been considered as an acceptable alternative and provides reasonable long-term results. Because some of the causes for its failure are related to the prosthetic material used, a technique that uses autologous material and is applicable in patients with unilateral common iliac lesions was developed. Iliofemoral crossover transposition is a femorofemoral bypass procedure in which the external iliac artery is used as a graft. The procedure is easily performed and avoids the use of prosthetic materials, minimizing the risks of their related complications. Because its biologic behavior, including hemodynamic performance, has proven to be excellent, satisfactory long-term results can be anticipated.

[Use of autologous superficial femoral artery in surgery for aortic prosthesis infection].

The surgical management of the aortic prosthesis infection still remains an enormous challenge for the vascular surgeon and a critical issue for the patient's integrity and life. Several techniques for its management have been devised and employed, along the years, but none of them revealed itself as totally satisfactory. This stimulates the creation of new alternatives. We present the clinical case of an infected aortic prosthesis in a 41 year old man, complicated by duodenal and ureteral erosion, in whom the autologous superficial femoral artery was employed successfully in the treatment of this most demanding situation.

["Ex-vivo" renal artery revascularization].

Three patients with renovascular hypertension due to complex and branch lesions of the renal artery are reported, successfully managed by a technique consisting in the "ex-vivo" repair of the lesions followed by kidney autotransplantation. The indications and technical details of the procedure are subjected to a description and discussion.

[Isolated obstructive lesions of the cervical common carotid: clinical and surgical aspects].

Isolated lesions of the extra-thoracic common carotid arteries are unusual in clinical practice. Contrarily to the well known lesions of carotid bifurcation, its natural history is poorly understood and indications for surgical management are not well defined. In this paper, seven patients with isolated lesions of the common carotid arteries are reported, being two symptomatic (TIA's). Patients underwent successful surgical management. The main features of clinical presentation, diagnosis and surgical management are presented and discussed

[Lower limbs revascularization originated in the descending thoracic aorta].

The revascularization of the lower limbs through a bypass graft from the descending thoracic aorta is one of the most uncommon surgical procedures within the scope of the so-called "extra-anatomic revascularization". It is an highly selective procedure in terms of indications and is regarded as an effective hemodynamic alternative, with acceptable long-lasting results. Two patients who underwent successfully the operation are reported, followed by a discussion on the technical aspects, indications, complications and early and late results of the procedure.

[The use of superficial femoral veins in reconstructive surgery of aortic prosthesis infection (Clagett's operation)].

Prosthetic aortic infection still represents an enormous challenge to the possibilities of contemporary reconstructive vascular surgery, particularly in terms of diagnosis and surgical management, and is accompanied by high mortality and morbidity rates. Several surgical methods have been devised and employed, including the extra-anatomic bypasses and the in "situ" revascularization. The later uses either antibiotic bounded prosthesis, or biologic homologous conduits, including cryopreserved allografts or autologous arteries and veins. The authors report the clinical condition of a 73 years old male with an infected aortic prosthesis, who underwent the complete removal of the infected graft, followed by an interposition of a venous autograft composed by two superficial femoral veins, removed from both thighs (Clagett's operation). The procedure was extremely well succeeded and the patient was discharged one month later. Reviewed one year later he was found in good condition and free of symptoms.

[Eversion carotid endarterectomy].

It is widely accepted and proved the role of carotid endarterectomy in the prevention of cerebrovascular insufficiency. Some mater of controversy lies, presently, apart the role of the endovascular treatment, in the techniques of choice for the endarterectomy, as well as in the method employed for the arteriotomy closure. The authors report their experience with the eversion endarterectomy technique, discussing the results and enhancing the main indications of this alternative method for carotid endarterectomy.

[Aneurysm of the superior mesenteric artery in the context of a multianeurismatic disease. Case report].

Aneurysms of the superior mesenteric artery are one of the most uncommon visceral artery aneurysms. Despite its rarity they course with high risks of rupture and many constitute a permanent threat to patients's life. The authors report the clinical condition of a male patient, with a large aneurysm of the superior mesenteric artery, diagnosed through the image techniques made during the follow-up of a previously operated aorto-iliac and bilateral popliteal aneurysms. Its clinical presentation and the surgical management are subjected to presentation and discussion.
