A case report of a difficult dissection of the iliac vessels conducted by means of the harmonic scalpel during a kidney transplantation

Background. The “difficult” preparation of iliac vessels in the kidney transplant recipient caused by a perivascular fibrosis with satellite lymphadenopathy is sometimes burdened by post-transplant complications (lymphocele, seroma and hematoma). Both iliac vascular adhesions and satellite lymphoadenopaty are often due to reiterate femoral cannulation aimed to hemodialysis. Patients and Methods: The case report concerns a 60 years old female uremic patient, on dialysis for about 4 years with perivascular fibrosis and pelvic lymphadenopathy caused by bilateral femoral artery catheterization. In the course of kidney transplant, preparation of the iliac vessels was performed by ultrasonic scalpel. In the case we handled there was no incidence of immediate, medium and long term post operative complications, with a considerable reduction of the operative time in the vascular dissection performed without ligation. Often the long dialytic period, the same nephropathy, reiterative femoral catheterization determine perivascular fibrosis and/or consensual lymphadenopathy. In these cases, in light of initial experience, the use of ultrasonic scalpel enables easy dissection by the coagulative synthesis not only of vascular compartment but also of the lymphatic duct whose leakage, particularly in these cases, creates a favourable condition to hematoma and / or lymphocele formation. These complications, although rarely jeopardize patient’s life, however, may affect the outcome of transplantation in terms of morbidity and survival of the organ. The use of ultrasonic scalpel ensures total control of vascular and lymphatic compartment coagulation, alongside a reduction in the time of surgical dissection.
