The catecholamine content of various blood vessels of the foreleg of the dog was measured by a fluorimetric method (48 vascular segments from 11 dogs) and also by bioassay (33 segments from 8 dogs). The results obtained by the fluorimetric method indicate that the average concentration of catecholamines in the brachial artery (0.14 /ig/g of wet tissue) was significantly lower than that in the u...

BACKGROUND Diabetic patients present higher level of red blood cell (RBC) aggregation contributing to the development of vascular complications. While it has been suggested that this hematology/rheology parameter could bring additional prognostic information for the management of those patients, RBC aggregation screening is not included as a clinical practice. Most medical centers are not equip...

OBJECTIVE The migration of peripherally inserted central catheters (PICCs) from the superior or inferior vena cava into the right atrium can pose a significant risk of lethal pericardial effusion and tamponade secondary to myocardial perforation. Arm movement has been reported to cause displacement of the catheter tip toward the heart and lead to ventricular tachycardia in adults. The objective...

PURPOSE Report on the anatomic qualification of the snuffbox radial artery (SBRA) and proximal radial artery (PRA) for pAVF.
 METHODS Retrospective analysis of upper extremity mapping in 64 limbs in 55 dialysis patients was performed. The radial artery was assessed for diameter, patency, flow and proximity to the adjacent vein to SBRA and PRA. Sites qualified for pAVF on a binary basis when t...

PURPOSE To retrospectively determine the incidence and outcome of angioplasty-induced ruptures that occurred during treatment of hemodialysis graft-related stenoses. MATERIALS AND METHODS During a five year period 1222 patients with dysfunctional or thrombosed polytetrafluoroethylene (PTFE) hemodialysis grafts underwent angioplasty procedures at our institution. Angioplasty-induced vascular r...

There are several very obvious and simple solutions for eliminating the "Pitfalls" and for minimizing the risk of occurrence of any perioperative complications associated with placement of chronic indwelling central venous access devices in cancer patients. The first is the utilization of a venous cutdown approach, such as the cephalic vein or the external jugular vein, which essentially elimin...

background the feasibility of safe full laparoscopic cephalic duodenopancreatectomy (cdp) has been demonstrated by several authors. objectives for its realization, we propose a 5 trocars approach. methods kocher maneuver is performed to reach the inferior vena cava, the infrarenal aorta, the rear plate of the uncinate process, and the superior mesenteric artery. lymphadenectomy in the region ca...
