Successful revascularisation of a thrombosed renal artery aneurysm in a young man with solitary kidney and history of severe hypertension.

Case report of a 18-year-old patient with long lasting hypertension, who developed acute renal failure, in course of an antihypertensive therapy modification, backgrounded by undiagnosed aneurysm of the solitary kidney renal artery. The acute renal function decrease was caused by single dose of ACE inhibitor causing an equivalent drop in serum ACE activity. Aneurysm excision followed by implantation of a venous bypass normalized restored renal function and blood pressure for over 24 months of observation.

The abnormal superficial radial artery does not restrict the successful creation of hemodialysis forearm arteriovenous fistula.

Anatomical variations of the radial artery are of clinical importance in end-stage renal disease patients awaiting creation of native arteriovenous fistula for hemodialysis. As radial-cephalic direct wrist fistula is a vascular access of choice, atypical localization of the distal part of the radial artery may lead to the false assumption of severe atherosclerotic lesions and prevent creation of such an access, despite good vessel conditions and convenient surgical approach. We present 7 patients with radial artery variations. In 5 patients with superficial radial artery, radial-cephalic direct wrist access was created. One patient, due to an anomaly misdiagnosis, had radial-cephalic fistula created on the contra lateral wrist. In the patient with hypoplastic radial artery brachial-basilic upper arm transposition was created.

Dissecting aneurysm of the thoracic aorta in a patient with nephrotic syndrome and brucellosis.

We report the case of a 61-year-old man with nephrotic syndrome due to glomerulonephritis and chronic brucellosis complicated by dissecting aortic aneurysm. The patient worked as a veterinarian and was diagnosed for chronic but non-active brucellosis with positive serum test for Brucella melitensis in the past. Administration of cyclosporine in combination with low dose prednisone resulted at least in proteinuria reduction and partial remission for 3 years. Dissecting aortic aneurysm was treated by insertion of a stent-graft, that resulted in canalization of blood flow and retraction of aneurysm wall later in the course in our patient.

Incidence and outcome of transplant renal artery stenosis: single center experience.

Since the incidence of transplant renal artery stenosis (TRAS) in renal allografts varies from 1% to 23%, we sought to examine its incidence, to analyze treatment options, and to ascertain its outcomes. Retrospective analysis of 793 kidney allograft recipients transplanted between 1996 and 2004 revealed an incidence of 0.9% (n = 7). Time from kidney transplantation to the first symptoms varied from 1 week to 3 years (median, 4 months). Three patients experiences refractory hypertension and six patients developed allograft dysfunction. Screening color Doppler ultrasonography showed hemodynamic changes in six patients with the definitive diagnosis confirmed by angiography in all patients. One patient with an anastomotic stenosis was treated with a surgical operation and six patients, percutaneous transluminal angioplasty (PTA), with stenting in three cases. Both surgical as well as PTA treatment were successful in all but one patient, who underwent PTA alone, developed chronic renal insufficiency necessitating hemodialysis and finally lost his allograft. In the other patients all symptoms resolved after treatment and the patients are doing well with functioning allografts. Although TRAS was an uncommon complication, if recognized promptly it could be treated by surgery or PTA with a high success rate.

[Complications after percutaneous biliary drainage and their clinical significance]. / Powiklania po przezskórnym drenazu dróg zólciowych i ich znaczeniekliniczne.

Percutaneous Biliary Drainage (PBD) is a simple, relatively painless and inexpensive palliative procedure, performed in cholestatic jaundice caused by non-operative neoplastic tumor of main biliary ducts (Klatskin's tumor). 60 cases of PBD were presented with special remarks concerning early and late complications. Proper technique preventing complications as well as schematic approach in late complications were described.

[Surgical complications after renal percutaneous transluminal angioplasty]. / Powiklania chirurgiczne po przezskórnej angioplastyce tetnic nerkowych.

In this article complications, occurred after 120 procedures of renal PTA, have been analyzed. Serious complications occurred in 7% of patients and required surgical operation. Reduction of amount of complications depends on settlement of adequate indications to PTA and experience of surgeons, making this procedures.
