A 51-year-old man was admitted because of hemoptysis. Physical examinations and chest XP revealed no abnormal findings. Fiberoptic bronchoscopy showed pulsatile bleeding at the orifice of right B6. Right bronchial arteriography showed a markedly dilated and tortous bronchial artery and shunting to the pulmonary arterial system in the middle and lower lobes. Pulmonary arteriography showed complete obstruction of the right middle lobar and lower lobe segmental arteries (A6, 9, 10). The hemoptysis was thought to be due to increased blood flow of the right bronchial artery, which compensated for reduced right pulmonary arterial flow. Right middle and lower lobe resection was done to prevent further hemoptysis. The resected specimen revealed old thromboemboli in the right middle and lower lobe pulmonary arteries. In this case old pulmonary embolism should be considered as a cause of intrabronchial bleeding.

The history, physical examination, chest radiograph, electrocardiogram and blood gases were evaluated in patients with suspected acute pulmonary embolism (PE) and no history or evidence of pre-existing cardiac or pulmonary disease. The investigation focused upon patients with no previous cardiac or pulmonary disease in order to evaluate the clinical characteristics that were due only to PE. Acute PE was present in 117 patients and PE was excluded in 248 patients. Among the patients with PE, dyspnea or tachypnea (greater than or equal to 20/min) was present in 105 of 117 (90 percent). Dyspnea, hemoptysis, or pleuritic pain was present in 107 of 117 (91 percent). The partial pressure of oxygen in arterial blood on room air was less than 80 mm Hg in 65 of 88 (74 percent). The alveolar-arterial oxygen gradient was greater than 20 mm Hg in 76 of 88 (86 percent). The chest radiograph was abnormal in 98 of 117 (84 percent). Atelectasis and/or pulmonary parenchymal abnormalities were most common, 79 of 117 (68 percent). Nonspecific ST segment or T wave change was the most common electrocardiographic abnormality, in 44 of 89 (49 percent). Dyspnea, tachypnea, or signs of deep venous thrombosis was present in 107 of 117 (91 percent). Dyspnea or tachypnea or pleuritic pain was present in 113 of 117 (97 percent). Dyspnea or tachypnea or pleuritic pain was present in 113 of 117 (97 percent). Dyspnea or tachypnea or pleuritic pain or atelectasis or a parenchymal abnormality on the chest radiograph was present in 115 of 117 (98 percent). In conclusion, among the patients with pulmonary embolism that were identified, only a small percentage did not have these important manifestations or combinations of manifestations. Clinical evaluation, though nonspecific, is of considerable value in the selection of patients in whom there is a need for further diagnostic studies.

The diagnostic features of acute pulmonary embolism among 72 patients greater than or equal to 70 years old were evaluated and compared with characteristics of pulmonary embolism among 144 patients 40 to 69 years and 44 patients less than 40 years old. Syndromes characterized by either 1) pleuritic pain or hemoptysis, 2) isolated dyspnea, or 3) circulatory collapse were observed with comparable frequency among patients greater than or equal to 70 years old and younger patients. One of these presenting syndromes occurred in 64 (89%) of the 72 patients greater than or equal to 70 years old. Those who did not show these syndromes were identified on the basis of unexpected radiographic abnormalities, which may have been accompanied by tachypnea or a history of thrombophlebitis. Among the 72 patients greater than or equal to 70 years with pulmonary embolism, dyspnea or tachypnea (respirations greater than or equal to 20/min) occurred in 66 (92%), dyspnea or tachypnea or pleuritic pain in 68 (94%) and dyspnea or tachypnea or radiographic evidence of atelectasis or a parenchymal abnormality in 72 (100%). Complications of angiography were evaluated among patients with and without pulmonary embolism. Major complications of pulmonary angiography among patients greater than or equal to 70 years old (2 [1%] of 200) were not more frequent than among younger patients (6 [1.1%] of 562) (p = NS). However, renal failure (major or minor) was more frequent in patients greater than or equal to 70 years old than in younger patients (6 [3%] of 200 versus 4 [0.7%] of 562) (p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

A 58-year-old female was admitted with an abrupt onset of chest and back pain. The CT scan of the chest showed aortic dissection of the ascending aorta and proximal aortic arch, but the false lumen of the aortic dissection had already been occluded by a blood clot. After admission, she complained of chest pain with hemoptysis and presented facial edema and the distention of the neck veins. The pulmonary angiogram showed complete occlusion of the right pulmonary artery at the proximal segment. These findings were interpreted as pulmonary embolism. She was treated with intravenous heparin and urokinase, but these treatments did not demonstrate any improvement. She underwent a surgical exploration on the fourth hospital day. During surgery, the right pulmonary artery was discovered to be compressed and occluded by the large dissecting aneurysm of the ascending aorta. In addition, hematoma was seen between the right pulmonary artery. The ascending aorta and pulmonary trunk, which was injured in the operative procedure, were replaced with an artificial graft successfully. Postoperative pulmonary angiogram showed no stenosis of right pulmonary artery. The occlusion of the pulmonary artery by an acute dissecting aneurysm is an extremely rare complication and it is often wrongly diagnosed as pulmonary embolism. In such cases, the correct diagnosis and prompt surgical treatment is essential and antithrombolytic and anticoagulant therapy should be avoided.

Two young men presented with prolonged hectic fever and chills followed by chest pain, dyspnea and hemoptysis. The chest films revealed multiple lung infiltrates, and blood cultures yielded Staphylococcus aureus. Echocardiographic examination confirmed the diagnosis of tricuspid valve endocarditis. Multiple punctate lesions in the bilateral inguinal areas and dragon tattoos over the forechest gave rise to the suspicion of drug abuse. After prolonged antimicrobial therapy, bacteremia was eliminated, and elective vegetectomy and valvuloplasty were performed on one of the patients. The other one suffered recurrent episodes of pulmonary embolism. Disappearance of the large vegetation was disclosed by echocardiography. Both of them eventually regained their health with the abstinence of drugs. This report illustrates two typical cases of infective endocarditis in drug addicts.

The anamnesis is believed to be poor in identifying patients with pulmonary embolism (PE), but the method of data collection may be critical for inference on this issue. We compared the prevalences of history findings recorded after a free verbal interview (VI) by the referring physicians with those recorded after completion of a standardized questionnaire (SQ) by the admitting physicians in a group of 177 consecutive patients referred to our Emergency Unit with the suspicion of PE (subsequently confirmed in 97). VI data were incomplete in 18 patients. In the remaining 159 patients, prevalences of symptoms and predisposing factors were higher after SQ than after VI. Accordingly, 8 items (obesity, prolonged immobilization, surgery, varicose leg veins, deep venous thrombosis, pleuritic chest pain, and sudden-onset dyspnea) were significantly more prevalent in patients with confirmed PE after SQ, compared to only 2 items (prolonged immobilization and pleuritic chest pain) after VI. When we tested for the agreement between the two methods of data collection, kappa values ranged from high values (for surgery and hemoptysis) to very low values (for prolonged immobilization and recurrent phlebitis). These results show that the use of an SQ could improve the accuracy of collecting clinical data in patients with suspected PE, as they are also consistent in separating patients with PE from those with unconfirmed suspicion of PE. Moreover, it allows the clinician to be alert towards findings which could be missed when not carefully searched for and which may be useful to raise or strengthen the suspicion of this disease.

Hemoptysis in systemic lupus erythematosus (SLE) may occur in up to 17% of cases. The vast majority of the cases are secondary to bacterial, tuberculosis or opportunistic infections. Also uremia, pulmonary embolism and lung hemorrhage must be considered. The majority of the above referred entities are usually alarming events in any patient with SLE. In contrast, we describe a patient with inactive SLE, who developed hemoptysis secondary to Paragonimus sp., which was treated "easily" with praziquantel. Fluke infection must be considered in the differential diagnosis of hemoptysis in SLE.

We describe the case of a 23 years old male, who suffered a 45 bullet wound in the arm and upper right hemithorax. He walked after his injury and 10 minutes later presented dizziness, cough and tachycardia. On admission a minor haemothorax was seen on a chest X ray, but the bullet was not seen. Even without symptoms, an X ray of abdomen showed the missile lying above the left sacroiliac joint. A chest tube was placed, the patient had an excellent recovery and was discharged a week later. After several months he presented hemoptysis and a moderate pain on his right chest and was treated as an acute bronchitis. Six months after his initial injury he developed a florid picture of acute pulmonary embolism (chest pain, dyspnea, hemoptysis, tachycardia, severe cough). A new chest X ray was done and the bullet was shown lying in the right chest. A pulmonary arteriography located it in a lower basal branch. Through a posterolateral thoracotomy the slug was obtained. The recovery was uneventful and he has remained well since. We discuss the possible mechanisms to explain the entrance of the bullet into the vascular system and conclude that in cases of gunshot wounds: a) An exit wound must be always searched for; if not found exploratory X ray are mandatory, b) If the bullet is not found, specially after thoracic injuries, bullet embolism should be contemplated, c) If there are signs of regional ischemia arteriography is mandatory.(ABSTRACT TRUNCATED AT 250 WORDS)

Twenty-six cases of excavated pulmonary masses are reported. In 18 cases malignancy was proven by transparietal needle aspiration. A false-negative result was due to the needle being introduced too centrally and bringing pus, whereas the tumour was an epidermoid carcinoma. The seven non-malignant lesions consisted of abscess in 4 cases, tuberculosis in 1 case and pulmonary embolism in 2 cases. The sensitivity and specificity of the technique were similar to those observed in large series of transparietal needle aspiration of solid masses. Using thin needles and extemporaneous cytology reduced the number of complications: haemothorax 6 percent, haemoptysis 0.4 percent. The authors conclude that in excavated pulmonary masses transparietal needle aspiration provides a diagnosis of malignancy when the radiological and clinical courses and bronchial fibroscopy are inconclusive. Transparietal needle aspiration avoids the need for other investigations, such as exploratory thoracotomy, thereby reducing the cost of diagnosis.

The various forms of bronchoplastic and angioplastic procedures are the best means of avoiding pneumonectomy. Essential indications are limited respiratory reserve and central site of a malignancy. In a retrospective study 248 broncho- and angioplastic operations carried out in the years 1973 to 1983 were analyzed. Reference date for the analysis of survival was January 1986. In consequence the minimum period of follow-up was two years. For all patients (n = 248) the 5-year-survival was 22% with a 30-day-lethality of 13%. The 5-year-survival of all bronchial sleeve resections operated radically (stage I and II of the TNM-classification) (n = 44) was 42% with a 30-day-lethality of 7%. The 5-year-survival of all bronchoplastic operations of stage I and II (n = 88) was 38% with a 30-day-lethality of 14%. Improved suture material and surgical techniques caused a reduction of operative lethality from 23% to 8% during the described period. In the first thirty postoperative days the following complications caused death: Hemoptysis (n = 5), insufficiency of the anastomosis (n = 3), right heart failure (n = 5), pulmonary embolism (n = 4) and sepsis (n = 1).
