Oesophagobronchial fistula caused by varicella zoster virus in a patient with AIDS: a unique case.
(17/163)
Human herpesvirus oesophagitis in human immunodeficiency virus positive patients is caused by cytomegalovirus and herpes simplex virus; no cases of oesophagitis and oesophagobrochial fistula as a result of varicella zoster virus (VZV) have been reported to date. This report describes the case of a patient with a 2-3 mm deep oesophageal ulcer whose viral culture was positive for VZV. The patient was treated with acyclovir with resolution of the symptomatology. After the end of the induction treatment, because of the onset of fever and fits of coughing during eating, the patient underwent oesophagography, which showed an ulcer with an oesophagobronchial fistula in the middle and lower third of the oesophagus. This case report stresses the role of VZV infection as a possible cause of oesophagobronchial fistula, a rare but benign condition in patients with AIDS. (+info)
Bronchoesophageal fistulae secondary to tuberculosis.
(18/163)
An elderly patient with a bronchoesophageal fistula secondary to tuberculosis and a 3-month history of cough and dysphagia worsening with deglutition was admitted to hospital. Radiological examination and CT of the thorax revealed mediastinal adenopathy. Bronchoscopy, esophagoscopy and esophagraphy confirmed the presence of a bronchoesophageal fistula. Histological examination of the esophagus and bronchial biopsy specimens revealed nonnecrotic granulomas, and the acid-fast bacilli tested positive for Mycobacterium tuberculosis in respiratory secretions. Antituberculous treatment was started after diagnosis of intrathoracic lymph node tuberculosis with bronchoesophageal fistulization. A month and a half after initiating treatment, paroxistic coughing during deglutition persisted. An esophagoscopy was performed, and the orifice was closed with a fibrin tissue. After 9 months of treatment, the patient was asymptomatic and in good health. (+info)
An unusual epistaxis.
(19/163)
The case of a man who presented complaining of epistaxis is reported. He had coarctation repair 18 years previously. Subsequent investigation revealed an aortobronchial fistula resulting from false aneurysm formation distal to the original vessel anastamosis. This was repaired at surgery, the patient suffering a minor stroke, before rehabilitation and good recovery. (+info)
Endovascular treatment in diseases of the descending thoracic aorta: 6-year results of a single center.
(20/163)
OBJECTIVE: The purpose of this study was to evaluate endovascular treatment in diseases of the descending thoracic aorta. MATERIAL AND METHODS: This study was designed as a single center's (university hospital) experience. Over a 6-year period (1995 to 2001), thoracic endografts were placed in 74 patients with a diseased descending thoracic aorta who were at high risk for conventional open surgical repair: 34 had atherosclerotic aneurysms, six had posttraumatic aneurysms, 14 had type B dissection with aneurysmal dilatation of the false lumen, 12 had isthmic transections from blunt trauma, five had thoracoabdominal aneurysms (treated with a combined procedure), two had aortic coarctation, and one had an aortobronchial fistula. Twenty-six procedures (35.1%) were conducted as emergencies, and 48 (64.9%) were elective. The feasibility of endovascular treatment and sizing of stent grafts were determined with preoperative spiral computed tomography and intraoperative angiography. RESULTS: Endovascular operations were completed successfully in all 74 patients; postprocedural conversion to open repair was necessary in three cases. The overall 30-day mortality rate was 9.5% (seven deaths). Temporary neurologic deficits developed in two patients; not one patient had permanent paraplegia. The primary endoleak rate was 20.3% (15 patients). The mean follow-up period was 22 months (range, 3 to 72 months). Five deaths occurred in the follow-up period, and three patients needed secondary conversion to open repair 2, 3, and 14 months after initial endografting. CONCLUSION: Endoluminal treatment in diseases of the thoracic descending aorta is feasible and may offer results as good as the open method. (+info)
Ventilator auto-triggering in a patient with tuberculous bronchopleural fistula.
(21/163)
We report a case of ventilator auto-triggering resulting from tuberculous bronchopleural fistula being managed with chest tube suction. Early recognition of bronchopleural fistula-related auto-triggering is extremely important. Auto-triggering can lead to serious adverse effects, including severe hyperventilation and inappropriate escalation of sedatives and/or neuromuscular blockers (administered to reduce spontaneous breathing efforts). Auto-triggering was confirmed in our patient when tachypnea persisted despite pharmacologic neuromuscular paralysis. Auto-triggering can be reduced or eliminated by decreasing ventilator trigger sensitivity or by decreasing the air leak flow by reducing the degree of chest tube suction. (+info)
An improved method of bronchial stump closure for prevention of bronchopleural fistula in pulmonary resection.
(22/163)
We performed 880 pulmonary resections from January 1982 to June 1988 using Sweet's procedure for closure of the bronchial stump, in which 39 patients (4.4%) developed bronchial fistulas. Bronchoscopic studies showed that bronchopleural fistulas were located mainly at the corner of the stump. This indicates that the corner is the point with the highest tension when Sweet's procedure is employed. In some cases, stumps were injured by suture materials, resulting in bronchopleural fistulas. Since July 1988, bronchial stumps have been closed by using two pairs of teflon pledgets with additional interrupted sutures. From July 1988 to April 1990, 288 patients were treated by this new method, and only one of them developed bronchopleural fistula. This new method prevents injury of the stump by suture material and reduces the tension at the bronchial stump for a long time. Thus, pulmonary resections can be safely employed even after anti-cancer chemotherapy and/or radiation therapy. (+info)
A 61 year old man died after presenting with a 24 h history of haematemesis and haemoptysis, and one year history of hoarseness of voice. Post-mortem examination showed a dental plate eroding through the mid-oesophagus into a bronchus and into the descending arch of the aorta, with scarring suggestive of old perforation. An organized haematoma also involved the left recurrent laryngeal nerve. Vocal cord paralysis may be a manifestation of foreign body-induced oesophageal perforation, which can lead to death from an oesophago-broncho-aortic fistula. Both complications of oesophageal perforation from a foreign body have not to our knowledge been previously reported. (+info)
Recurrent hemoptysis due to aortobronchopulmonary fistula of false aortic aneurysm associated with repair of rupture of the sinus of Valsalva.
(24/163)
A 54-year-old man presented with recurrent hemoptysis of one year duration. Computed tomography (CT) and magnetic resonance imaging (MRI) demonstrated a saccular aneurysm of the ascending aorta. The aneurysm was intraoperatively found to have formed on the superior surface of the site of aortotomy suture placed during previous repair of rupture of the sinus of Valsalva and to have a fistulous communication to the lung. CT and MRI were very useful in the diagnosis of the aneurysm as the cause of hemoptysis. (+info)
