RESUMO

We describe the ultrasound-Doppler and angio-CT findings of the internal carotid string-of-beads sign in a patient with fibromuscular dysplasia (FMD). FMD is a disease of unknown etiology typically affecting the medium and larger arteries of young and middle-aged women. The most commonly affected arteries are the renal arteries followed by the internal carotid arteries. The lumbar, mesenteric, celiac, hepatic and iliac arteries are less commonly affected. Patients typically present with renovascular hypertension in case of renal artery involvement, Transient ischemic attack or stroke can be one of the presenting symptoms in carotid artery involvement.

RESUMO

The typical pathological finding in the pancreas of patients with the Shwachman-Diamond syndrome is fatty infiltration. In this report it is emphasized that this lipomatosis can be demonstrated by non-invasive techniques, using abdominal ultrasound and CT-scan.

RESUMO

The results of CT scan are discussed with special reference to the value of density measurements in several cases of mediastinal cyst lesions. Although in some cysts with watery content, the CT attenuation values can be indicative, in most other lesions with heterogeneous structure and viscid fluid content, attenuation values in CT scan cannot be considered conclusive for diagnosis.

RESUMO

The complications related to the use of subclavian catheters for hemodialysis were prospectively studied in 257 consecutive acute and chronic renal failure patients. Using 394 catheters, 3006 single needle dialyses were performed. Indications for starting catheter dialysis were mainly the absence or disappearance of an adequate vascular access. Most hazardous complications were sepsis (9), malposition (6), hemothorax (3), bleeding (2), vena cava thrombosis (2) and pneumothorax (2). A number of mechanical problems occurred, where the obstructed catheter could easily be replaced by a modified Seldinger technique. No mortal complications occurred. Patient tolerance was excellent. It is concluded that single needle subclavian hemodialysis is a valuable alternative vascular access method in acute situations. It enables the continuation of hemodialysis on an ambulatory basis.
