1/4. Transcolonic retrograde ureteric catheterization assisted by 3-D computed tomography.A 42-year-old woman had bladder exstrophy at birth, treated by ureterocolic anastomosis of her single kidney. She suffered recurrent hyperammonaemia, leading to comas, but refused an ileal conduit. During her most recent coma, it was decided to divert her urine to test whether this would reduce hyperammonaemia: this was accomplished by transcolonic retrograde catheterization of the ureter. This was only possible after computed tomography ureterography to show the ureterocolic anastomosis.- - - - - - - - - - ranking = 1keywords = catheterization (Clic here for more details about this article) |
2/4. Focal seizure and cerebral contrast retention after cardiac catheterization.Although rare, ionic and nonionic contrast-induced seizures occur as a complication of enhanced cranial computed tomography for both adults and children. However, contrast-induced seizures after cardiac catheterization has only been reported in adults. This report describes an 18-month-old male who developed a new-onset focal seizure 12 hours after cardiac catheterization. Unenhanced cranial computed tomography 1 hour after the seizure demonstrated general cerebral edema and unilateral focal cerebral contrast retention with sparing of the area supplied by the middle cerebral artery. The contrast was reabsorbed from the subarachnoid space over a 48-hour period, the cerebral edema resolved over several days, and the child returned to his baseline state 4 days after the seizure episode. This study documents the evolution of computed tomographic findings after contrast-induced seizures in a child. Contrast toxicity should be considered in any case of a new-onset neurologic deficit arising after angiography or enhanced computed tomography.- - - - - - - - - - ranking = 1.2keywords = catheterization (Clic here for more details about this article) |
3/4. cardiac tamponade from misplaced central venous line in pericardiophrenic vein.A patient in whom a left internal jugular vein catheter had first migrated into the left pericardiophrenic vein, and subsequently had perforated into the pericardium leading to a cardiac tamponade is described. Although this malposition has rarely been reported, it does not seem to be so infrequent, as three other similar misplacements have occurred in our institution. This malposition can be prevented by a high degree of suspicion, preferential use of the right internal jugular vein for catheterization, routine use of a J-tipped guidewire, limiting the depth of insertion of the guidewire during cannulation, routine roentgenographic control of radiopaque catheters, and (slow) injection of a small volume of radiopaque dye through the central venous catheter.- - - - - - - - - - ranking = 0.2keywords = catheterization (Clic here for more details about this article) |
4/4. Case of chorioamnionitis in an immunocompetent woman caused by morganella morganii.morganella morganii is an opportunistic organism that leads to serious morbidity. It is an enteric organism commonly associated with immunocompromise and chronic urinary catheterization. We present a case of a healthy gravid individual who presented with chorioamnionitis and neonatal seizures associated with M. morganii. This organism, which causes severe morbidity, is fortunately rare in obstetrics and gynecology.- - - - - - - - - - ranking = 0.2keywords = catheterization (Clic here for more details about this article) |
