This study describes an alternative arteriovenous fistula (AVF) model in the rat in which the animals develop significant neointimal hyperplasia (NIH) not only at the distal anastomotic site, but also throughout the fistula body. This aortocaval fistula was established by anastomosing the distal end of the renal vein to the abdominal aorta after unilateral nephrectomy. The increased hemodynamic...

Primary adrenal leiomyosarcoma has been reported previously in 25 patients. The patient presented herein is the only case where the definitive diagnosis was made with core needle biopsy evaluation. A 45-year-old male presented with pain in the back and right groin. Radiological evaluation demonstrated a heterogeneous 11 cm right adrenal mass, multiple liver masses, and an enlarged aortocaval ly...

Good multidisciplinary communication is crucial to the safe management of women requiring non-elective Caesarean section. Anaesthetists should participate actively in resuscitation of the fetus in utero; relief of aortocaval compression is paramount. Epidural top-up with levobupivacaine 0.5% is the anaesthetic of choice for women who have been receiving labour epidural analgesia. If epidural to...

With this October issue, CLÍNICAS begins to introduce a new style. At this point we have started to reorganize our Editorial Board to cover a worldwide spectrum of expertise. Next, will be internet online submission and handling of manuscripts which we hope to have operational by early 2005. We are looking forward to receiving your original paper, or your case report. In this issue we are publi...

W e report the unusual case of a 60-year-old-man presenting with left lower limb venous gangrene caused by an aorto-caval fistula. There was associated bilateral lower limb and scrotal oedema. In this case a ruptured aortic aneurysm with acute fistulation into the vena cava (fig 1) was repaired in the conventional manner. However, the patient underwent above-knee amputation of irreversible veno...

We report a case of secondary rupture of a common iliac artery aneurysm into the common iliac vein. Exclusion of the iliac aneurysm had been performed 2 years earlier in association with reconstruction of an aortic aneurysm that had ruptured into the interior vena cava. After closure of the aortocaval fistula by the endoaneurysmal route, aortobifemoral bypass grafting had been performed and a c...
