[Prosthetic repair of the aorta with a cadaveric homograft for infection of bifurcated synthetic vascular prosthesis]. / Protezirovanie aorty trupnym gomograftom pri infitsirovanii bifurkatsionnogo sinteticheskogo sosudistogo proteza.

Infection of arterial vascular grafts is a rare but utterly severe complication in vascular surgery. Therapeutic policy in patients with graft infection has not been standardized, to be determined individually. One of the variants of surgical treatment is considered to be repeat aortic repair using a cadaveric graft. Presented in the article is a clinical case report concerning a 60-year-old male patient previously subjected to aortofemoral bifurcation bypass grafting with stage IV ischaemia of lower limbs according to the Pokrovsky-Fontaine classification. In the early postoperative period the events of critical ischaemia were not arrested. Due to the presence of a block of the femoropopliteal segment, as the second stage 3 days after the primary operation, the patient underwent autovenous femoropopliteal bypass grafting with a reversed autovein above the knee-joint fissure. The clinical course of critical ischaemia of the limb was relieved. During subsequent 8 months of follow up his state remained stable. Eight months after the primary operation he developed purulent discharge from the postoperative scar on the left femur. In the setting of the Purulent Surgery Department, the patient was emergently subjected to opening and drainage of the abscess of the postoperative scar. On the bottom of the wound there was a freely lying branch of a synthetic vascular prosthesis. Computed tomography revealed infection of the entire synthetic prosthesis and aneurysms of distal anastomoses. Given extremely high risk for the development of arrosive haemorrhage, a decision was made on operative treatment - repeat prosthetic repair of the abdominal aorta with a cadaveric allograft. At the Vascular Department of the Clinic of Faculty Surgery, laparotomy was performed, with removal of the infected graft, followed by debridement of the retroperitoneal space and repeat aortofemoral bifurcation prosthetic repair of the abdominal aorta with a cadaveric allograft. The wound healed with first intention. There was no evidence of infectious process relapse. The patient was discharged on postoperative day 15 in a satisfactory condition. The duration of follow up amounted to 6 months. The control examination showed that the pain-free walking distance was 500 m. Doppler ultrasonography demonstrated that the graft was functioning, with no signs of either anastomotic aneurysms or suppuration of the retroperitoneal space.

[Surgical treatment of a patient with a ruptured Crawford type III thoracoabdominal aortic aneurysm]. / Khirurgicheskoe lechenie bol'nogo s razryvom torakoabdominal'noi anevrizmy III tipa po E.S. Crawford.

Described herein is a clinical case report regarding surgical treatment of a patient presenting with a ruptured Crawford type III thoracoabdominal aortic aneurysm. The patient was subjected to prosthetic repair of the thoracoabdominal aorta by the Coselli technique, as well as reduction of the aneurysmal sac in the thoracic and abdominal portions according to the authors' technique. The operation was carried out with neither connecting the patient to a heart-lung machine nor use of pharmacological protection of the visceral organs. The sutures were removed on postoperative day 12 and the patient was discharged from hospital in a satisfactory condition.
