UNLABELLED Anal fistula is a benign inflammatory disease with unclear etiology which develops in approximately 10 in 100 000 adult patients. Surgical treatment of fistulae is associated with a risk of damaging anal sphincters. This usually happens in treating high fistulae, branched fistulae, and anterior ones in females. In preoperative diagnosis of anal fistulae, endosonography and magnetic r...

Coronary fistulae and ventricular septal perforation are very rare clinically, and even less caused by cardiac leiomyosarcoma. A case is reported that a 67-year-old female had cardiac leiomyosarcoma with progressive heart failure and coronary fistulae and ventricular septal perforation. This case was special since all ante-mortem examinations and cardiac surgery failed to detect the presence of...

introduction: while the development of fistulae is a well-known complication of radiotherapy, such fistulae can often be challenging to manage. case presentation: we describe the case of a 37 year old male who developed in succession a urethrocutaneous fistula to the thigh, a rectourethral fistula and a peritoneo-urethral fistula 35 years after radiotherapy for pediatric pelvic rhabdomyosarcoma...

Dural arteriovenous fistulae of the transverse and sigmoid sinuses are highly variable in symptomatology and prognosis. However, we have identified a subgroup of patients who have a high risk of hemorrhage and dementia due to severe venous overload caused by high arterial flow into the fistulae and by occlusive changes of the transverse and sigmoid sinuses. Three representative cases selected f...

Congenital pulmonary arteriovenous fistulae, provided that they are not present in very large numbers, are best managed surgically, and there is no effective alternative management. Where pulmonary arteriovenous fistulae develop as a consequence of pulmonary hypertension it is rational to resect the fistulae if the cause of pulmonary hypertension - for example, mitral stenosis - is correctable....

BACKGROUND AND OBJECTIVES Given different sites of stenosis and access blood flow rates (Qa), the criteria for diagnosing fistula stenosis might vary according to anastomotic site. To test this, we analyzed the database of a prospective blinded study seeking an optimal bedside screening program for fistula stenosis. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Several methods used during dia...

UNLABELLED This study provides the long-term follow-up data on the efficacy of infliximab in the treatment of chronic refractory pouchitis complicated by fistulae following ileo-pouch anal anastomosis (IPAA) for ulcerative colitis (UC). METHODS Seven patients (4 F, 3 M) with chronic refractory pouchitis complicated by fistulae were included in an open study. Pouchitis was diagnosed by clinica...

Aortoenteric fistulae are rare but potentially catastrophic entities that can affect either a diseased or reconstructed abdominal aorta and therefore they are classified as pr imary or secondary fistulae. The subtleties of its presentation, lack of specific diagnostic tests, delay in therapy and lack of consensus on the optimal operative t reatment have contributed to the high morbidi ty and mo...

PRESENTATION Dural arteriovenous fistulae are relatively rare lesions which can present a variety of different symptoms ranging from tinnitus to devastating intracranial hemorrhage. For those fistulae that require treatment, therapy is available in a wide range of options. We describe the case of a 60-year old patient who presented with a right occipital lesion presumably secondary to a dural a...

In recent years increasing numbers of percutaneous renal biopsies are being performed, occasionally resulting in complications such as arteriovenous (AV) fistulae. Over 35% of all renal AV fistulae are formed secondary to percutaneous biopsy. In the past patients with bleeding fistulae were treated surgically, but more recently transcatheter embolization has become a recognized form of therapy....
