Stereological evaluation of liver volume in living donor liver transplantation using MDCT via the Cavalieri method. 总被引:4,自引:0,他引:4
Cihan Duran Bulent Aydinli Yaman Tokat Yildiray Yuzer Mecit Kantarci Metin Akgun Kamil Yalcin Polat Bünyami Unal Refik Killi S Selcuk Atamanalp 《Liver transplantation》2007,13(5):693-698
In living donor liver transplantation (LDLT), obtaining the precise volume of the graft is very important to decrease volume-related postoperative complications, especially in cases with suspected small-for size grafts. We used stereology based on the Cavalieri method (CM), a new method to measure liver graft volume, and compared the results with those obtained through intraoperative measurement (IOM) and through multidetector computed tomography (MDCT) measurement. Liver volumes estimated using the 3 methods were well-correlated with each other (r(2) = 0.94 and P < 0.001 for IOM and CM; r(2) = 0.91 and P < 0.001 for IOM and MDCT, and r(2) = 0.95 and P < 0.001 for CM and MDCT); however, they were different from each other (in descending order, 908 +/- 124 cm(2), 861 +/- 121 cm(2), and 777 +/- 168 cm(2) for MDCT, CM, and IOM, respectively). Although MDCT and CM overestimated the volumes, the results of CM were almost similar to those obtained via IOM. In conclusion, our results suggest that CM measured the liver graft volume more reliably. Thus, its use, particularly in cases with suspected small-for-size graft, may prove useful. 相似文献

Abstract – Traumatic dental injuries often occur to the teeth and their supporting tissues and they are the main reasons for emergency visit to a dental clinic. Management of a fracture depends on its position and the extent of root involvement. Horizontal root fractures are not seen frequently and the treatment consists of reduction and long‐term rigid fixation of the coronal segment. The present case demonstrates the successful management of two horizontally fractured maxillary central incisors with a follow‐up period of 9 months. 相似文献

Retention is a major part of orthodontic treatment, not an optional secondary protocol. In recent years, studies investigating dentofacial changes during and after the growth period have led most clinicians to use fixed retention appliances after treatment. Fixed retainers can be attached to the teeth directly or indirectly. We present a practical, indirect method for bonding fixed retainers, using Sondhi Rapid-set Indirect Bonding Adhesive (3M Unitek, Monrovia, Calif). 相似文献

Iatrogenic injuries to ureter, bladder and urethra during abdominal and pelvic operations 总被引:1,自引:0,他引:1

Abdominal and pelvic operations at Departments of Obstetrics and Gynaecology, and General Surgery play an important role in
ureteral, bladder and rarely urethral injuries.
Fifty-nine patients with iatrogenic ureteral, bladder and urethral injuries were treated at the Department of Urology, Atatürk
University Research Hospital, between 1985 and 1995. These injuries were urinary vaginal fistulas in 43 patients (vesicovaginal
33, ureterovaginal 7, urethrovaginal 2 and vesicovaginal plus urethrovaginal 1), ureteric ligation in 9, bladder laceration
in 7. These injuries were treated by different methods. All patients were followed up by intravenous urography (IVU) and urine
culture three months later.
It must be borne in mind that iatrogenic urinary tract injuries are not rare. Bladder and ureteral catheterization must be
performed to prevent these complications. 相似文献

A retrospective study was carried out on 40 children from Saudi Arabia with Henoch-Sch?nlein syndrome to delineate its clinical pattern. More than 50 per cent of the cases occurred in winter. There was no apparent causal relationship with B-haemolytic streptococcal infection. All patients had skin rash. Fifty-eight per cent had gastrointestinal manifestations, 58 per cent had joint manifestations and 38 per cent had renal manifestations. The main clinical features of Henoch-Sch?nlein syndrome in Saudi children are comparable to those reported elsewhere. 相似文献

Abdominal Stab Wounds in Children: an 18-Year Experience 总被引:1,自引:0,他引:1

Objective: Evaluation of the diagnosis, management, and the role of selective treatment in children with abdominal stab wounds.
Patients and Methods: 59 children (56 male and three female) were included in the study. The patients' median age was 11.8 years (range, 5–14 years).
Time between injury and admission was about 3 h. Laparotomy was performed in 44 patients (74%). Solid organ injury was detected
in 32 of these patients (73%) and could not be observed in twelve (27%). 15 patients (26%) were treated conservatively, and
only one (6.6%) underwent laparotomy during the follow-up. The stomach was the most frequently injured organ (ten patients),
followed by the intestines (nine patients). Types of surgical treatment were as follows: primary suture in 28 patients, resection-anastomosis
in three, and osteotomy in two.
Results: Some prognostic factors such as presence of abdominal organ evisceration and pneumoperitoneum were not significantly correlated
with intraabdominal organ injury, whereas some other risk factors such as acute abdomen on admission (p < 0.002) or abdominal
clinical and hemodynamic findings (p < 0.001) showed significant correlation with intraabdominal organ injury. The relative
risk (odds ratio) of developing an intraabdominal organ injury was > 2 for patients with signs of an acute abdomen on admission.
Postoperative complications were observed in five patients with organ injuries. None of our patients died.
Conclusions: Conservative treatment can be safely performed in most children with abdominal stab injuries. Signs of major internal hemorrhage
or generalized peritonitis are an absolute indication for emergency operation for abdominal stab wounds. Peritoneal penetrations,
free air on the abdominal X-ray, and omental or intestinal evisceration are poor indicators of significant organ injuries,
and patients presenting these signs shold be closely followed up for developing acute abdominal symptoms.
