Hereditary hemorrhagic teleangiectasia (HHT) is known to be associated in 15% with pulmonary arterio-venous fistulas (PAVF). Symptoms and complications of these fistulas are: hemoptysis, dyspnea, hemothorax, cerebral embolization and brain abscess. We studied a family with 7 members known to have HHT. 3 had PAVF. Patient 1 died of a hemothorax and pleural empyema. PAVF were diagnosed at autopsy. Patient 2 (nephew) suffered from a cerebellar abscess. The fistula-bearing part of the lung was removed by wedge resection. Patient 3 (son of the former) had no symptoms, but the arterial PO2 was 6.7 kPa. In order to prevent complications like in his father, the patient was operated. A lobar resection was necessary to remove the fistula. The postoperative course was eventless in patients 2 and 3. We conclude, that periodical thorax X-ray studies are indicated for all members of families with HHT in order to find PAVF before complications occur. The classical treatment is resection of the fistula with as little lung tissue as possible. Good results have been reported lately with embolization of PAVF, but this method is not generally available yet.

The rise in incidence of lung abscess due to opportunistic organisms has reemphasized the need for early recognition and treatment. Opportunistic organisms can cause lung abscess in immunocompromised hosts. Most lung abscesses are primary, occurring as a result of aspiration of oral contents into the dependent portions of the lung in persons with dysphagia or decreased consciousness. Symptoms of lung abscess include productive cough, fever, leukocytosis, weight loss, and putrid sputum. Among the complications are progression to a chronic stage, empyema, massive hemoptysis, metastatic brain abscess, and bronchopleural fistula. Treatment of lung abscess is primarily medical, consisting of an appropriate antibiotic regimen and chest physical therapy. Surgery is reserved for unresponsive patients or those with complications.

The quality of life of adolescent patients with congenital heart disease (CHD) who have not undergone intracardiac repair was investigated by assessing the physical activity, complications, and the educational and occupational status of 69 patients (32 males and 37 females, average age 18 +/- 2 years) who had graduated from junior high school by April 1993. Group A consisted of 54 patients with mild CHD (small left-to-right shunt disease, mild aortic stenosis and/or regurgitation, and other CHD) who reported to have no symptoms. Group B consisted of 15 patients who complained of restrictions on physical activity associated with CHD (Eisenmenger syndrome, and CHD complicated with pulmonary atresia or severe pulmonary stenosis). All group A patients were in NYHA class I, and none had had serious complications due to CHD. Their heart condition had not been a disadvantage in terms of educational and occupational opportunities after graduation from junior high school. All group B patients in NYHA class II had reduced physical activity. Eleven patients suffered from complications associated with CHD, such as brain abscess, infective endocarditis, Down syndrome, supraventricular tachycardia, brain infarction, hemoptysis, mental retardation associated with conotruncal anomaly face syndrome, and I degree AV block without symptoms. Two remained at home after graduation from junior high school, and four after high school. Only two of 15 obtained full time jobs after graduation from high school. About half of the patients with symptomatic CHD are unable to participate actively in society since graduation from junior high or high school.(ABSTRACT TRUNCATED AT 250 WORDS)

Bronchiectasis is pathologically defined as an abnormal and permanent dilatation of one or several bronchi. There are localized and generalized types of bronchiectasis. A vicious circle hypothesis, including an initial insult to the lower airways, impaired mucociliary clearance, microbial colonization/infection, bronchial obstruction and a local inflammatory response, has been proposed to explain the damage to the bronchial tree and the adjacent lung parenchyma. The clinical picture is variable and affected individuals might be asymptomatic or suffer from severe respiratory failure. Daily sputum production is the most common, though unspecific symptom of bronchiectasis. Other common symptoms are hemoptysis and recurrent episodes of sputum purulence, fever and pleurisy. Occasionally, major, life-threatening hemoptysis from a ruptured bronchial artery occurs. Infectious complications, e.g. lung abscess, empyema, brain abscess, and secondary amyloidosis are rarely seen today. The chest radiograph reveals changes suggestive of bronchiectasis in the majority of patients with clinically important disease. High resolution computed tomography of the lung has almost completely replaced bronchography for diagnosis, the latter rarely being of value if surgery is contemplated. No etiology is identified in about one- to two-thirds of the patients, although there are many diseases eventually associated with bronchiectasis. Prevention and therapy of underlying diseases are most important. Traditionally, the therapy of symptomatic bronchiectasis is based on antibiotics, antibronchoobstructive medication, and chest physical therapy. Surgical resection is the treatment of choice for localized symptomatic disease. Bilateral lung transplantation should be considered in younger patients with severe, generalized bronchiectasis and respiratory failure. Prospective, randomized, largescale trials supporting any of the different treatment strategies are not available, but antibiotics and surgery probably have improved the long-term outcome of many patients with bronchiectasis. In this review, some recent findings regarding the classification, pathogenesis, pathology, etiology, diagnosis, treatment, and prognosis of bronchiectasis are discussed.

A total of 100 patients of tetralogy of Fallot aged 13 years and over were operated upon at the All India Institute of Medical Sciences, New Delhi, India between January 1991 and December 1996. There were 69 males (69%) and 31 females (31%). Age ranged from 13 years to 43 years (mean 19.66 years). Twenty % of patients had preoperative complications like haemoptysis, cerebrovascular accidents, brain abscess and infective endocarditis. Twenty-two patients had previous palliative shunts. Fifteen patients had coil embolisation of major collaterals prior to surgery. In hospital mortality rate was 4%. Follow-up ranged from 1 month to 5 years (mean 3.4 years). There was one late death due to infective endocarditis. Postoperatively 93.6% patients were in NYHA class I. Significant residual defects warranting re-operation were present in three patients. Total correction of tetralogy of Fallot in older patients can be performed with acceptable results.

Transcatheter therapy is an effective technique in the treatment of vascular abnormalities in the chest. Pulmonary arteriovenous malformations, associated with the clinical sequellae of dyspnea, stroke, brain abscess, and hemoptysis, can be treated by transcatheter embolization with metallic coils or occlusion balloons. The results of treatment are excellent, with improvement seen in symptoms and physiologic parameters. The bronchial arteries and systemic nonbronchial collateral arteries supplying the tracheobronchial tree are most frequently involved in massive hemoptysis, a serious disorder with associated high rates of morbidity and mortality. Transcatheter embolization of these arteries is both safe and effective, requiring a thorough understanding of the arterial anatomy and technique of embolization.

Cyanotic congenital heart diseases constitute about 10 percent of total congenital heart disease cases in adults in the developing world. Prolonged cyanosis and old age adversely affect the outcome of surgery, thus posing a challenge to the cardiac surgeons. This study was conducted to assess the feasibility, safety and outcome of surgery in this group of patients. From January 1991 to December 1997, a total of 303 patients, aged 14 to 54 years (mean 19.8 +/- 1.5 years) with diagnosis of various cyanotic congenital heart diseases were operated at our institute. There were 210 males (69.3%). Two hundred and forty-seven patients (81.5%) had tetralogy of Fallot's physiology, 51 patients (16.8%) had single ventricle physiology and five (1.6%) had other lesions. Sixty-six patients (21.7%) had pre-operative complications such as haemoptysis, epistaxis, cerebrovascular accidents, brain abscess and infective endocarditis. Sixty patients (19.8%) had previous palliative shunts and 26 patients (8.5%) had coil embolisation of major aortopulmonary collaterals prior to surgery; 229 patients (75.5%) underwent biventricular repair, 52 (17.1%) had univentricular repair, 22 (7.7%) had palliative shunts and one patient had open ligation of a major aortopulmonary collateral in addition. In-hospital mortality was 3.3 percent. Follow-up period ranged from five months to seven years (mean 4.2 +/- 1.8 years). There were two late deaths. Of the 291 survivors, 11 were lost to follow-up. Two hundred and fifty-eight patients (92.1%) are in New York Heart Association class I. Significant residual defects warranting reoperation were present in four patients (1.3%). It is concluded that congenital heart surgery in older cyanotic patients can be performed safely with satisfactory results.

Pulmonary arteriovenous fistulas (PAVFs) are rare vascular malformations of the lung. There is a strong association with Rendu-Osler-Weber disease. Although most patients are asymptomatic, PAVFs can cause dyspnea from a right-to-left shunt. They can also bleed and result in hemoptysis and hemothorax. Because of paradoxical emboli, various central nervous system complications have been described including stroke, and brain abscess. Currently, spiral computed tomography offers the most practical method for establishing the presence of PAVFs. Most patients should be treated. Therapeutic options include angiographic embolization with metal coils or balloon occlusion and surgical excision. Angiographic treatment has become the mainstay of therapy for most patients during the last decade. It is less invasive and can be repeated easily. Surgery, which usually consists of a conservative lung resection, is associated with low morbidity and a low recurrence rate. Both therapeutic approaches are discussed. The Mayo Clinic surgical experience of the last 20 years for PAVFs is presented.

In the last years, the understanding of HHT has greatly progressed. The two genes for most on cromosomes 9 and 12 have been discovered and the existence of a third involved gene has been predicted. Recent progress in the field of genetics has allowed the identification of many gene mutation thus facilitating the characterisation of the at risk members of the same family. Complications from bleeding or shunting (pulmonary AVMs) may be sudden and life-threatening (hemothorax, haemoptysis, stroke and brain abscess). Catastrophic events are preventable by early diagnosis and treatment. Appropriate screening programmes are mandatory and multi-specialistic cooperation is needed. Special centers have been developed in the world, where physicians, who are specialised and trained in all aspects of HHT, are working to develop better therapeutic approaches for the disease and to locate new genes in view of the future potential of gene therapy for this condition.

Pulmonary arteriovenous malformation (PAVM) consists of abnormal communications between the pulmonary arteries and veins. Because PAVM may cause neurological defects (such as stroke and brain abscess) or hemoptysis and hemothorax, embolization therapy or surgery is required. Resection using video-assisted thoracic surgery (VATS) has recently been performed for small peripheral PAVMs. For large or hilar PAVM, surgical resection with thoracotomy is required. We report herein a case of PAVM (4.0 x 3.5cm) located in the left S6 segment near the lung hilum that was resected successfully using simultaneously stapled S6 segmentectomy (simultaneous stapling of anomalous vessels of the PAVM and hillar structures of S6) with VATS.
