1/166. Post-traumatic arterial priapism evaluation with color Doppler ultrasonography: a case report.The patient was a 19-year-old man who was examined due to persistent penile erection, which appeared following a blow to the perineal region during work. color Doppler ultrasonography of the corpora cavernosa revealed a cavity in one part of the cavernous artery that suggested a blood leak, and a diagnosis of high flow type priapism due to trauma was made. Bilateral internal pudendal arteriography demonstrated dilation and extravasation in one part of the right cavernous artery, then transarterial embolization was performed superselectively in the right cavernous artery using an autologous clot. However, 2 weeks after treatment, slight penile erection reoccurred. color Doppler ultrasonography revealed reformation of the cavity at the treated lesion, and embolization was again performed using a gelatin sponge. Following embolization, the course proceeded satisfactorily without any relapse. color Doppler ultrasonography, which is non-invasive and can be easily performed, is considered to be an effective means for diagnosis and follow up of arterial high flow priapism.- - - - - - - - - - ranking = 1keywords = leak (Clic here for more details about this article) |
2/166. Application of skull base techniques to pediatric neurosurgery.Techniques for skull base surgery have become well established over the last 10 years. Most of these techniques are used in adult patients for skull base tumors and neurovascular diseases. There are very few large series of pediatric patients in whom skull base approaches have been used, because of the rarity of these conditions. The authors would like to present a relatively large series of 26 pediatric patients who underwent skull base approaches for tumor resection. These tumors involved the anterior cranial base in 5 patients, the medial cranial skull base in 4 patients, and the posterior cranial base in 12 cases. Five patients had tumors that involved two or more fossae. The overall complication rate was 57%, which included temporary cranial nerve palsies, CSF leak and infection. patients with permanent complications were 8 in number (37%). There was 1 postoperative death from pneumonia approximately 6 weeks after surgery. Complete tumor removal was achieved in 24 of the 26 patients. skull base tumors in children are often extensive and present significant surgical challenges. Although complete tumor extirpation is the goal in most pediatric patients, this is often achieved only with some morbidity. This paper demonstrates the effectiveness of skull base approaches for these tumors and underscores the high stakes involved.- - - - - - - - - - ranking = 1keywords = leak (Clic here for more details about this article) |
3/166. Prepartum mixed type cavernous-capillary hemangioma arising in nevus flammeus.OBJECTIVE: Capillary hemangioma may appear de novo and involute during the first decade of life, but rarely during pregnancy. This study describes the clinical and histologic findings of an eyelid mixed type cavernous-capillary hemangioma arising in a nevus flammeus and discusses the differential diagnosis of this lesion. STUDY DESIGN: Clinicopathologic case report. INTERVENTION: A reddish, protruding eyelid mass arising from a nevus flammeus at the eyelid margin in a 26-year-old woman was monitored during her pregnancy. Postpartum, the mass was excised and examined histologically. RESULTS: The lobulated tumor recurred during the second pregnancy and partially regressed following delivery. It was composed of mixed elements of cavernous and capillary hemangioma that superficially resembled Kaposi sarcoma, set against the background of a nevus flammeus. CONCLUSION: The differential diagnosis of discrete prepartum vascular tumor arising in nevus flammeus includes mixed capillary-cavernous hemangioma, pseudo-Kaposi sarcoma, granuloma gravidarum, and angiodermatitis. A common stimulus during pregnancy may be the inciting factor for the development of these tumors.- - - - - - - - - - ranking = 10.2758634733keywords = capillary (Clic here for more details about this article) |
4/166. Treatment of the systemic capillary leak syndrome with terbutaline and theophylline. A case series.BACKGROUND: The systemic capillary leak syndrome is a rare idiopathic disorder characterized by recurrent episodes of hypotension and hemoconcentration due to sudden transient extravasation of 10% to 70% of plasma. mortality rates 5 years after diagnosis have been reported to be 76%. OBJECTIVE: To assess the efficacy of a prophylactic regimen for the systemic capillary leak syndrome. DESIGN: Case series. SETTING: Tertiary referral center. patients: Eight patients followed over the past 18 years. INTERVENTION: Oral terbutaline plus aminophylline or theophylline. MEASUREMENTS: Long-term clinical follow-up. RESULTS: During a median follow-up of 9 years (range, 2 to 18 years), two patients (25%) died: one during an acute episode and one of complications related to long-term corticosteroid therapy. The other six patients are alive and healthy. The frequency and severity of the episodes decreased by a median of 30-fold. Recurrences were associated with decreased serum theophylline levels, possibly caused by enzyme induction or autoinduction. The extended-release form of medication was more successful. Sympathomimetic side effects were significant. CONCLUSIONS: A regimen of terbutaline and theophylline seems to be effective prophylaxis against the systemic capillary leak syndrome. maintenance of therapeutic drug levels was associated with favorable results.- - - - - - - - - - ranking = 3188.2945132359keywords = capillary leak syndrome, systemic capillary leak syndrome, systemic capillary leak, capillary leak, leak syndrome, systemic capillary, capillary, leak (Clic here for more details about this article) |
5/166. Central retinal vein occlusion during remission of ulcerative colitis.BACKGROUND: Retinal vascular disease is a rare complication of ulcerative colitis. CASE: We report a patient who developed unilateral nonischemic central retinal vein occlusion (CRVO) (papillophlebitis) without any other retinal vascular disease during remission of ulcerative colitis. OBSERVATIONS: The best-corrected visual acuities were 1.5 OD and 0.7 OS. Dilated and tortuous retinal veins and retinal bleeding were seen in the left eye. macular edema and leakage from the papilla and the retinal veins of the left eye were evident on fluorescein angiography. After increased dosage of systemic prednisolone was prescribed, the retinal vascular changes resulting from CRVO (papillophlebitis) in the left eye gradually abated. CONCLUSIONS: Retinal vascular diseases should be monitored during both remission and activation of intestinal symptoms of ulcerative colitis.- - - - - - - - - - ranking = 1keywords = leak (Clic here for more details about this article) |
6/166. Repeat syncopal attacks due to postsurgical right ventricular pseudoaneurysm.Pseudoaneurysm of the right ventricular outflow tract is a rare lesion caused by disruption of the ventricular wall that allows the blood to leak into the surrounding space. It often complicates surgery involving right ventriculotomy and progressively increases in size, therefore causing airway compression, pulmonary perfusion asymmetry, thromboembolism, and rupture. We report on a patient who developed right ventricular pseudoaneurysm early after surgery for atrio-ventricular septal defect with tetralogy of fallot and needed emergency surgical repair due to low cardiac output and repeat syncopal attacks.- - - - - - - - - - ranking = 1keywords = leak (Clic here for more details about this article) |
7/166. Contralateral tension pneumothorax following unilateral chest tube drainage of bilateral pneumothoraces in a heart-lung transplant patient.Bilateral pneumothoraces can result from unilateral air leak after heart-lung transplantation. The recommended initial management of such patients is insertion of a unilateral chest tube. We report a patient who developed bilateral pneumothoraces after undergoing transbronchial biopsies 2 years after a heart-lung transplant. The unilateral chest tube failed to drain the contralateral pneumothorax and a tension pneumothorax developed. The advocated approach should be used with caution.- - - - - - - - - - ranking = 1keywords = leak (Clic here for more details about this article) |
8/166. rupture of abdominal aortic aneurysms: A concurrent comparison of outcome of those occurring after endoluminal repair versus those occurring de novo.AIM: to compare the outcome of patients whose abdominal aortic aneurysm (AAA) ruptured following endoluminal repair with those whose AAA ruptured prior to treatment. patients: over a 4-year period 434 patients underwent treatment for AAA with conventional open (n=253) and endoluminal repair (n=181). Of those having open repair, 216 patients had elective operations while 41 had operations for ruptured AAA. Four patients with ruptured AAA had undergone endoluminal repair previously (Group I) while the remaining 37 patients ruptured de novo (Group II). The patients in both groups were similar in age and sex but differed clinically. All four patients in Group I had major medical co-morbidities versus 56% in Group II (p<0.05). All patients in group I had a known endoleak following endoluminal repair. All patients underwent open repair. RESULTS: the proportion of patients presenting with hypotension in Group I (1/4) was significantly less than in Group II (30/37). The difference in 30-day mortality for Group I (0%) compared with that for Group II (43%) was significant. The four patients in Group I remain alive and well at follow-up 22 months after operation. The outcome for Group I was better than Group II despite the higher incidence of medical co-morbidities. CONCLUSION: endoluminal AAA repair complicated by a persistent endoleak does not protect from rupture, which may not be accompanied by such major haemodynamic changes and high mortality as rupture de novo. Further long-term results in more patients are required to confirm this intermediate level of protection.- - - - - - - - - - ranking = 2keywords = leak (Clic here for more details about this article) |
9/166. Congestive heart failure treated by the upgrade from VVI to DDD pacing.The case is presented of an elderly woman with normal left ventricular (LV) systolic function and VVI pacing complicated by severe congestive heart failure. The symptoms and findings of congestive heart failure became refractory to medical treatment and resolved with the upgrade of the VVI to a DDD system. Right heart catheterization during VVI pacing showed increased mean pulmonary capillary wedge and right atrial pressures both being normalized under DDD pacing. This case report illustrates the need to consider permanent physiological pacing in elderly patients, even in presence of normal LV systolic function, to ensure AV synchrony when the atrium can be paced, since diastolic LV dysfunction is quite common in these subjects.- - - - - - - - - - ranking = 1.4679804961858keywords = capillary (Clic here for more details about this article) |
10/166. Conservative treatment of postsurgical lymphatic leaks with somatostatin-14.Successful management of lymphatic leaks by continuous IV administration of somatostatin was first reported by Ulibarri and coworkers in spain,(1) and more recently by authors from italy(2) and switzerland.(3) The present article reports the clinical history of two patients in whom postsurgical lymphatic leak was successfully treated after the administration of either somatostatin-14 alone (case 1) or combined somatostatin-14 and total parenteral nutrition (TPN; case 2). Although further pathophysiologic studies are needed for the elucidation of its mechanisms of action, somatostatin-14 seems to be an intriguing therapy against postsurgical lymphatic leaks that may make potentially risky transthoracic reoperation unnecessary.- - - - - - - - - - ranking = 7keywords = leak (Clic here for more details about this article) |
