Endovascular treatment of huge saccular abdominal aortic aneurysm in a young Behcet patient: mid-term result.

BACKGROUND: Abdominal aortic aneurysm formation is among the arterial complications of Behcet's disease. Weakness and fragility of aortic walls leads to the development of arterial complications like pseudoaneurysms. CASE PRESENTATION: A case of huge saccular abdominal aortic aneurysm in a young Behcet patient who was successfully treated with endovascular stent graft placement is reported, diagnostic and interventional procedures are discussed, and mid-term follow-up results are presented. CONCLUSIONS: Endovascular treatment of abdominal aortic aneurysm complications of young Behcet patients who are not suitable for open surgery and need intervention could be an alternative treatment modality even without performing preprocedural angiography.

Effects of testicular microlithiasis on Doppler parameters: report of three cases.

BACKGROUND: Testicular microlithiasis is a rare, usually asymptomatic, non-progressive disease of the testes associated with various genetic anomalies, infertility and testicular tumors. According to our literature search, there is no specific data about Doppler findings in this disease. CASE PRESENTATION: Doppler findings of three cases of testicular microlithiasis during last two years in our institution are presented. CONCLUSIONS: Although our hypothesis was to find increased Doppler parameters due to intratesticular arterial compression, our findings suggest that there are no Doppler findings specific to testicular microlithiasis.

Evoked cavernous activity.

PURPOSE: Corpus cavernosum electromyography has been widely done to evaluate autonomic dysfunction in patients with erectile dysfunction. We assessed the value of corpus cavernosum electromyography, evoked cavernous activity and penile sympathetic skin responses for their accuracy in determining autonomic involvement in cases of erectile dysfunction. MATERIALS AND METHOD: We evaluated 75 men with erectile dysfunction by corpus cavernosum electromyography, evoked cavernous activity and penile sympathetic skin response tests at our neurourology laboratory. The etiology of dysfunction was vascular, neurogenic, psychogenic or mixed based on a detailed medical and sexual history, physical examination, electrophysiological and laboratory studies, penile color Doppler ultrasonography, and cavernosography and/or cavernosometry. Autonomic involvement was clinically assessed by systemic findings, such as orthostatic hypotension, impaired gastrointestinal motility, sinus dysrhythmia and secretomotor changes. A concentric electromyography needle placed in the right cavernous body was used to record corpus cavernosum electromyography and evoked cavernous activity. The right median nerve was stimulated electrically with 13 to 16 mA. to determine evoked cavernous activity and the penile sympathetic skin response. The latter response was recorded with silver disc electrodes placed on the left cavernous body. All tests were performed using an electromyography/evoked potential machine. We determined the relationships among corpus cavernosum electromyography, evoked cavernous activity and penile sympathetic skin response tests in respect to etiological factors. RESULTS: The 56 patients with normal corpus cavernosum electromyography activity had also evoked cavernous activity and a penile sympathetic skin response except for 1 with no penile sympathetic skin response but evoked cavernous activity. None of these patients had autonomic neuropathy. Of the 19 patients without corpus cavernosum electromyography activity 11 had evoked cavernous activity, including 10 with no autonomic neuropathy. The remaining 8 patients had no evoked cavernous activity, of whom 7 had autonomic neuropathy. A penile sympathetic skin response was recorded in 18 men with absent corpus cavernosum electromyography. CONCLUSIONS: Due to false-negative results on corpus cavernosum electromyography and penile sympathetic skin response testing evoked cavernous activity seems more reliable for determining autonomic involvement in the pathophysiology of erectile dysfunction.

Glutaric aciduria type I diagnosed after poliovirus immunization: magnetic resonance findings.

Glutaric aciduria type I is an uncommon inborn error of metabolism. It is a serious disease, often with a fatal outcome. Magnetic resonance imaging findings and the clinical course of monozygotic twin females with glutaric aciduria type I who were admitted with acute encephalopathic crisis symptoms 3 days after immunization for poliovirus are presented in this report. Magnetic resonance imaging findings revealed hyperintensity in the putamen, head of the left caudate nucleus, and globus pallidus, periventricular white matter (on T(2)-weighted images), arachnoid cysts in bilateral temporal regions, and enlargement of the sylvian fissures. Glutaric aciduria type I should be included in the differential diagnosis of patients with acute encephalopathic crisis occurring shortly after poliovirus immunization. Typical magnetic resonance findings guide urinary organic acid analysis in these patients.

Cervical hematomyelia: a rare entity in a neonate with cesarean section and surgical recovery.

Spinal cord injury with or without trauma has been reported in the perinatal period. The prognosis depends primarily on diagnosis of the level, extent and nature of the lesion, established by correlations between clinical, imaging and electrophysiological data. A 25-day-old boy with normal birth weight delivered at term by cesarean section was transferred to Inönü University Turgut Ozal Medical Center because of respiratory distress and brachial diplegia. A suspicious medullary lesion on cervical computerized tomography was confirmed as an intramedullary lesion extending from C3 to D1 on magnetic resonance imaging (MRI). Emergent surgery consisting of exposure of the lesion site and interlaminar direct puncture of the lesion under fluoroscopy revealed that the pathology was an intramedullary hematoma. The partial evacuation of the lesion with direct puncture, the patient's neurological improvement and close follow-up of the patient with ultrasonography, electrophysiology and MRI are discussed in the light of recent literature.

Quantitative Doppler evaluation of the splenoportal venous system in various stages of cirrhosis: differences between right and left portal veins.

PURPOSE: The purpose of our study was to evaluate the relationship between the splenoportal hemodynamics in patients with cirrhosis and the stage of the disease. METHODS: Patients with cirrhosis were grouped according to modified Child-Pugh scoring into stages A, B, and C of cirrhosis. A control group of healthy volunteers was included. After gastroenterologic clinical and laboratory examinations, all participants underwent a splenoportal Doppler sonographic evaluation in which the vessels' diameter, area, and blood flow velocity were measured and blood flow rate and the congestion index in the splenoportal venous system were calculated. RESULTS: Seventy-five patients with cirrhosis (25 women and 50 men) were enrolled; the control group consisted of 30 healthy volunteers (15 women and 15 men) with no liver disease. The mean age (+/- standard deviation) of the patients was 54.4 +/- 14.8 years (range, 13-80 years) and of the control subjects was 47.3 +/- 14.5 years (range, 18-72 years). No significant differences in vessel diameter, blood flow velocity, and blood flow rate were found in the main and left portal veins between the study group and the control group. In the right portal vein, we found decreases in the vessel diameter, blood flow velocity, and blood flow rate, and in the splenic vein, we found increases in vessel diameter and blood flow rate. The congestion index was increased in the main portal and splenic veins but was unchanged in the left portal vein. CONCLUSIONS: Although our data indicate that there is no difference in Doppler sonographic parameters of the main portal vein according to Child-Pugh scores, the hemodynamic differences between the left and right branches of the portal vein may be clinically useful in patients with cirrhosis.

Bare stent implantation in iatrogenic dissecting pseudoaneurysm of the superior mesenteric artery.

Iatrogenic arterial dissection leading to the development of dissecting pseudoaneurysms of the superior mesenteric artery (SMA) is a rare complication of angiography. Surgical and endovascular treatment options exist for this important condition. We report a case of bare stent implantation in dissecting pseudoaneurysm of the SMA that developed after angiography in a patient with acute mesenteric ischemia. Although it is rarely published, iatrogenic arterial dissection causing pseudoaneurysm can occur after diagnostic and interventional angiography. Bare stent implantation in dissecting pseudoaneurysm of the SMA could be an advantageous endovascular treatment option in selected cases due its to potential preservation of important side branches of the SMA.
