Imaging of peripheral arteries by 16-row multidetector computed tomography angiography: a feasible tool?

OBJECTIVE: To evaluate the efficacy of multidetector (16-row) computed tomography (MDCT) in imaging the upper and lower limb arterial tree in trauma and peripheral arterial occlusive disease (PAOD). METHODS: Thirty-three patients underwent MDCT angiography (MDCTA) of the upper or the lower limb on 16-row MDCT scanner between November, 2004 and July, 2005. The findings were compared with the surgical outcome in cases with trauma and suspected arterial injuries or color Doppler correlation was obtained for patients of PAOD. RESULTS: MDCTA allowed a comprehensive diagnostic work-up in all trauma cases with suspected arterial injuries. In the 23 cases of PAOD, MDCT adequately demonstrated the presence of stenosis or occlusion, its degree and extent, the presence of collaterals and plaques. CONCLUSION: Our experience of CT angiography (CTA) with 16-row MDCT scanner has clearly demonstrated its efficacy as a promising, new, fast, accurate, safe and non-invasive imaging modality of choice in cases of trauma with suspected arterial injuries and as a useful screening modality in cases of PAOD for diagnosis and for grading.

The pattern of renal vessels in live related potential donors pool. A multislice computed tomography angiography review.

OBJECTIVE: To assess the renal vessel anatomy, compare the findings with the perioperative findings, to determine the sensitivity of multislice computed tomography (CT) angiography in the work-up of live potential donors and to discuss and compare the results of the present study with the reported results using single slice CT, magnetic resonance (MRI) and conventional angiography (CA). METHODS: Retrospective analysis of the angiographic data of 118 of prospective live related kidney donors was carried out from October 2004 to August 2005 at the National Organ Transplant Centre, Tripoli Central Hospital, Libya. All donors underwent renal angiography on multislice (16-slice) CT scan using 80 cc intravenous contrast with 1.25 mm slice thickness followed by maximum intensity projection (MIP) and volume rendering techniques (VRT) post-processing algorithms. The number of vessels, vessel bifurcation, vessel morphology and venous anatomy were analyzed and the findings were compared with the surgical findings. RESULTS: Multislice spiral CT angiography (MSCTA) showed clear delineation of the main renal arteries in all donors with detailed vessel morphology. The study revealed 100% sensitivity in detection of accessory renal vessels, with an overall incidence of 26.7%, which is the most common distribution in the parahilar region. CONCLUSION: The present study showed 100% sensitivity in the visualization and detection of main and accessory renal vessels. These results were comparable with conventional angiography which has so far been considered as the gold standard and were found superior in specificity and accuracy to the use of single slice CT (SSCT) and MR in the angiographic work-up of live renal donors. Due to improved detection of accessory vessels less than 2 mm in diameter, a higher incidence of aberrant vessels was seen on the right side as has been suggested so far.

Kidney transplantation in Libya: a North African and Middle Eastern perspective.

OBJECTIVES: In August 2004, a national organ transplant program utilizing the latest policies, procedures, and protocols was begun in Libya. During the first year of the program, 50 kidney transplantations from living donors were performed. MATERIALS AND METHODS: Forty-nine patients (aged 7 to 65 years) received kidneys from living-related donors (aged 19 to 54 years), and 1 husband received a kidney from his wife. Donor selection was based on human leukocyte antigen compatibility. Renal failure was due to chronic glomerulonephritis in most patients, diabetes in 5 adults, systemic lupus erythematosus in 2 adults, and congenital anomalies in 2 children. Sixteen patients matched the human leukocyte antigens of their donors, 28 matched 1 haplotype, and 6 did not match any haplotype. Immunosuppression was accomplished with methylprednisolone and basiliximab. Maintenance therapy was with mycophenolate mofetil, cyclosporine, and prednisone. The latter was completely discontinued 1 month after transplantation. In patients with resistant hypertension, unilateral native nephrectomy was carried out during transplantation. Donor nephrectomy was performed through an open mini-incision using a Thompson retractor. RESULTS: At the time of this writing, 49 patients are alive and well, and 48 of them have had functioning kidneys for 10 to 22 months. Three patients had acute rejections that were successfully treated with methylprednisolone (n=1) or methylprednisolone and antithymocyte globulin (n=2). At the time of this writing, all 46 adults and 2 pediatric recipients have excellent renal function and are living normal lives. CONCLUSIONS: In terms of patient survival and quality of life, transplantation is superior to dialysis. Also, transplantation is less expensive than dialysis. In Libya, establishing an active and successful transplant program with early steroid withdrawal has brought many benefits to patients and their families and great financial savings to the government. Our program hopefully will provide a model for similar programs in Asia and Africa and encourage local governments to legalize organ procurement from cadaveric donors.

Trichobezoar.

Trichobezoar is an uncommon condition often presenting, among other signs, with a history of trichotillomania and trichophagia. We report an unusual case of gastric trichobezoar with extension into jejunum in a patient with an unusual habit of ingesting hair plucked from other people's scalp.
