Emergency endovascular embolization of traumatic intrarenal arterial pseudoaneurysms with N-butyl cyanoacrylate.
AIM: The aim of this study is to report the effectiveness of selective endovascular embolization with N-butyl cyanoacrylate (NBCA) in the treatment of traumatic intrarenal arterial pseudoaneurysms. MATERIALS AND METHODS: Five patients (four males and one female) presented with massive haematuria. Five pseudoaneurysms were detected angiographically, and in all of the cases the aetiology was penetrating trauma. The pseudoaneurysms ranged in size between 7 and 30 mm (mean: 13.8 mm). After the superselective catheterization with a microcatheter-microguidewire system, embolization was performed using NBCA and Lipiodol mixture. RESULTS: All the pseudoaneurysms were successfully embolized and excluded from the circulation without any other major intrarenal arterial branch occlusion. There were no major or minor complications related to the embolization procedures. Haematuria ceased in 1-3 days after the embolization, and during the follow-up period both re-bleeding and deterioration of renal function did not occur. CONCLUSION: The endovascular management of renal artery branch pseudoaneurysms by embolization with NBCA is a reasonable and an effective therapeutic technique.

Computed tomography-guided percutaneous catheter drainage of primary and secondary iliopsoas abscesses.
AIM: To report our experience with computed tomography (CT)-guided percutaneous catheter drainage (PCD) of iliopsoas abscesses. MATERIALS AND METHODS: Twenty-two iliopsoas abscesses in 21 patients (11 women, 10 men) aged between 18 and 66 years (mean 36 years) were treated with PCD. Abdominal CT demonstrated the iliopsoas abscesses, which were definitively determined by Gram staining and aspirate cultures. Twenty of the 22 iliopsoas abscesses were primary and two were secondary. All PCD procedures were performed under local anaesthesia using a single-step trocar technique (n=19) or Seldinger technique (n=3). RESULTS: PCD was an effective treatment in 21 out of the 22 iliopsoas abscesses. Recurrence was seen in three abscesses as minimal residual collections. Two of them resolved spontaneously with anti-tuberculous regimen. One required percutaneous needle aspiration. The procedure failed in a diabetic patient with a secondary abscess, who died due to sepsis. The length of time that catheters remained in place ranged from 21 to 75 days (mean 59.7 days). Complications included catheter dislocation in four abscesses, which required removal of dislocated catheters and indwelling new ones. CONCLUSION: CT-guided PCD is a safe and effective front-line treatment of iliopsoas abscesses. Surgery should be reserved for failure of PCD and presence of contraindications to PCD.

Percutaneous embolization in the management of intractable vaginal bleeding.
AIM: To assess the effectiveness of arterial embolization in gynecological malignancies by Polyvinyl Alcohol particles. MATERIAL AND METHODS: Six patients, four with cervix carcinoma, one endometrium carcinoma, and one vaginal metastasis of ovarian carcinoma underwent percutaneous embolization due to intractable vaginal bleeding. As an embolic agent PVA particles were used. RESULTS: Cessation of the bleeding was observed immediately after the embolization. Complete embolization has been achieved in all the patients Recurrent bleeding did not occur in any of the cases. There were no complications related to the embolization procedure. CONCLUSION: Transarterial embolization is a lifesaving procedure in treating intractable vaginal bleeding. PVA particles are effective and it is a simple way in ceasing the hemorrhage due to pelvic malignancies.

Laparoscopic enucleation of giant liver hemangioma.
The cavernous hemangioma is the most common benign tumor of the liver. It usually becomes symptomatic as it reaches a certain size. A 49-year-old man was admitted with a 1-year history of epigastric pain, which was not relieved by regular analgesic intake, and nausea. The results of physical examination, routine laboratory tests, and upper gastrointestinal tract endoscopy were normal. Ultrasonography showed a 10-cm mass in the left hepatic lobe. Magnetic resonance imaging (MRI) showed a 90-mm hemangioma at left hepatic lobe. Selective celiac arteriogram was performed, and polyvinyl alcohol particles were used as an embolizing agent. After the embolization, the patient underwent laparoscopic enucleation of the liver hemangioma. No blood transfusion was needed during the operation. The operative time was 75 min. The patient was allowed to take a clear liquid diet on the postoperative day 1. The postoperative course of the patient was uneventful, and he was discharged on the postoperative day 2. Enucleation is the best surgical technique for the management of symptomatic giant hemangiomas. It can be performed with no mortality or morbidity, with preservation of all normal liver parenchyma. Enucleation also has been associated with significantly fewer intraabdominal complications than anatomic resection. The laparoscopic approach for enucleation requires patience and careful dissection to prevent bleeding. In conclusion, laparoscopic enucleation of hemangiomas is safe and easy to perform in selected cases.

Cephalic vein and hemodialysis fistula: surgeon's observation versus color Doppler ultrasonographic findings.
The aim of this study was to evaluate whether preoperative color Doppler ultrasonography improves immediate success rates of arteriovenous fistulas for dialysis. One hundred twenty-four patients with chronic renal failure underwent color Doppler ultrasonographic examination of both arms, including the cephalic vein, before arteriovenous fistula construction. Patients were randomly divided into 2 groups: A and B. In group A, there were 52 patients, and the surgeon planned to construct arteriovenous fistulas depending only on physical examination. In group B, which comprised 72 patients, surgeons performed arteriovenous fistula construction on sites labeled by color Doppler ultrasonography. In group A, of 52 patients who had surgery for arteriovenous fistula construction, 13 had fistulas that did not function. Among these 13 patients, 8 were found to have chronic thrombotic changes in the cephalic vein on color Doppler ultrasonography, and 5 had none of these changes. When we checked the color Doppler ultrasonographic findings, we noted that these 5 patients had decreased volume flow in the radial artery. On the whole, the arteriovenous fistulas worked in 39 patients (75%) and did not function in 13 patients (25%). In group B, surgeons followed the color Doppler ultrasonographic results. Of 72 patients who underwent the procedure, 68 patients (94.4%) had functioning fistulas, whereas 4 (5.6%) had fistulas that did not work. These 4 patients were found to have low volume flow in the radial artery. When both groups were compared by chi2 analysis, the difference was statistically significant (P = .002). Group B, in which patients were preoperatively evaluated by color Doppler ultrasonography, had a high success rate. We found that color Doppler ultrasonography is very helpful as a noninvasive procedure for this evaluation. Although many surgical clinics still perform arteriovenous fistula construction without the aid of color Doppler ultrasonographic findings, we think that the use of color Doppler ultrasonography should be emphasized before surgeons proceed with arteriovenous fistula construction.

Color Doppler ultrasound in subclinical varicocele: an attempt to determine new criteria.
OBJECTIVE: The aim of this study is to determine new criteria in the diagnosis of subclinical varicocele in infertile patients. METHODS: A total of 208 testes in 104 patients who were infertile and had no varicocele on physical examination were studied by color Doppler ultrasonography (CDUS) with classical and new criteria. Population proportion difference test was used to compare two methods. RESULTS: One hundred and fourteen testes were accepted as varicocele negative in the same testes units in both methods. Ninety-four testes were varicocele positive with new criteria while 88 of these 94 testes were diagnosed also varicocele positive with the classical criteria. The value of Z* with population proportion difference test was 0.59 which is less than 1.96, which means the proportion of varicocele detection in two methods did not differ. CONCLUSION: Because a gold standard that defines the presence of a subclinical varicocele has not yet been established, new criteria may be needed. However, our new criteria did not add new information to the diagnosis of subclinical varicocele in infertile patients.

Pulmonary arterial aneurysms in Behçet's syndrome: a report of 24 cases.
Pulmonary arterial involvement is an important complication of Behçet's syndrome (BS). Among 2179 patients with BS, 24 (1.1%) were diagnosed as having pulmonary arterial aneurysms (PAAs). Haemoptysis was the presenting symptom in all but one. All were male. The mean age at the time of the diagnosis of PAA was 30 +/- 11 S.D. yr (range 17-59 yr). Their mean disease duration was 5 +/- 4 yr (range 3 months-16 yr). There was a high prevalence of thrombophlebitis (21/24, 88%). Histopathological examination showed pulmonary vasculitis involving all layers of pulmonary arteries and veins. Twelve patients (50%) died after a mean of 9.5 +/- 11 S.D. months (range 1-36 months) after the onset of haemoptysis. The mean duration of follow-up of the remaining 12 patients was 25.5 +/- 24 S.D. months (range 1-78 months). The treatment consisted mainly of pulsed or oral cyclophosphamide alone or with prednisolone. As is true with other severe manifestations of Behçet's syndrome, PAAs are more common among males. They are associated with a prevalence of thrombophlebitis and there is high mortality despite treatment.

Behçet disease: pulmonary arterial involvement in 15 cases.
PURPOSE: To describe findings at radiologic evaluation of pulmonary arterial involvement in Behçet disease. MATERIALS AND METHODS: Between 1978 and 1993, 31 pulmonary arterial aneurysms were diagnosed in 15 consecutive male patients, aged 21-56 years (mean, 32 years 5 months), with known Behçet disease. The patients were assessed at chest radiography (n = 15), computed tomography (n = 14), angiography (n = 10), and magnetic resonance (MR) imaging (n = 2). RESULTS: Three patients had single and 12 had multiple pulmonary aneurysms. In six patients, aneurysms were associated with pulmonary artery occlusion. Follow-up chest radiography revealed five subjects with progression leading to fatal rupture of aneurysms and two subjects with regression of the aneurysms and cessation of their symptoms. CONCLUSION: Intravenous digital subtraction angiography was the procedure of choice in the documentation of pulmonary arterial involvement, and MR imaging was most helpful in the presumptive diagnosis of occluded aneurysms. The appearance of pulmonary aneurysms represents a poor prognosis in patients with Behçet disease, but there is a chance that the aneurysms will not rupture.

[Caroli syndrome].
In 1958 Caroli described the syndrome of congenital, either segmental or involving the entire bile duct system, saccular extensions of the intrahepatic bile ducts. He differentiated between two types of this disease pattern. The first form concerns pure cystic dilatations of the intrahepatic bile ducts, whereas the second one is combined with hepatic fibrosis and portal hypertension. Both types are characterised by cystic dilatations in the kidneys and in the extrahepatic bile ducts, pancreas and spleen.

Cavernous hemangioma of the kidney. Case report.
Renal hemangiomas are rare neoplasms of the kidney, and the number of cases reported in the literature are about 200 since the original description by Virchow in 1867. Among these, only a few have been examined by the combination of ultrasound, computed tomography, and angiography. We present a demonstrative case diagnosed at our clinic and review the corresponding literature.

Management of a patient with hepatic-thoracic-pelvic and omental hydatid cysts and post-operative bilio-cutaneous fistula: a case report.
In humans, most hydatid cysts occur in the liver and 75% of these are single. Our patient was a 31 year-old male. His magnetic resonance imaging (MR) showed one cyst (15 x 20 cm) in the right lobe and three cysts (5 x 6 cm, 8 x 6 cm, and 5 x 5 cm) in the left lobe of the liver, two cysts (4 x 5 cm and 5 x 5 cm) on the greater omentum, and two cysts (15 x 10 and 10 x 10 cm) in the pelvis. The abdomen was entered first by a bilateral subcostal incision and then by a Phennenstiel incision. Partial cystectomy + capitonnage was done on the liver cysts; the cysts on the omentum were excised, and the pelvic cysts were enucleated. The cyst in the right lobe of the liver was in communication with a thoracic cyst. An air leak developed from the thoracic cyst which had underwater drainage and bile drainage from the drain in the cavity of the right lobe cyst. Sphincterotomy was done on the seventh post-operative day by endoscopic retrograde cholangiopancreatography (ERCP). No significant effect on mean bile output from the fistula occurred. Octreotide therapy was initiated, but due to abdominal pain and gas bloating the patient felt and could not tolerate, it was stopped on the fourth day; besides, it had no decreasing effect on bile output during the 4 days. Because air and bile leak continued and he had bile stained sputum, he was operated on on post-operative day 18. By right thoracotomy, the cavity and the leaking branches were closed. By right subcostal incision, cholecystectomy and T-tube drainage of the choledochus were done. On post-operative day 30, he was sent home with the T-tube and the drain in the cavity. After 3 months post-operatively, a second T-tube cholangiography was done, and a narrowing in the distal right hepatic duct and a minimal narrowing in the distal left hepatic duct were exposed. Balloon dilatation was done by way of a T-tube. Bile drainage ceased. There was no collection in the cavity in follow-up CT scanning, so the drain in the cavity, and the drainage catheter in the right hepatic duct were extracted. Evaluation of the biliary ductal system is important in bilio-cutaneous fistulas, and balloon dilatation is very effective in fistulas due to narrowing of the ducts.

Posttraumatic high-flow priapism treated by N-butyl-cyanoacrylate embolization.
A patient with high-flow priapism was treated by transcatheter embolization of a posttraumatic left cavernosal arteriovenous fistula using N-butyl-cyanoacrylate (NBCA), resulting in complete detumescence. Erectile function has been preserved during a 3-month follow-up. Only two patients with NBCA embolization for high-flow priapism have been reported previously.
