“…Histologic examination of resected specimens in this series as in other studies (Cudkowics, 1952;Darke and Lewats, 1968;Tadavarthy et al, 1982) showed extensive anastornotic channels between bronchial and pulmonary arteries. Consequently, blood will flow from the high pressure (bronchial) to the low pressure circulation (pulmonary) through the newly established bronchopulmonary shunts.This haemodynamic event was demonstrated in our patients during thoracic arotogrpahy as retrograde filling of the pulmonary artery (Fig.…”

This explanation of the previously described left bronchus syndrome (Ashour et al., 1990, Thorax, 45:210-212) is based on a prospective study of 17 additional cases with unilateral lung destruction. It is likely that the anatomic peculiarities of the left main bronchus predispose the left lung to more frequent bronchial obstruction and hemodynamic changes than the right. Broncho-pulmonary shunt formation and retrograde filling of the pulmonary artery most likely lead to increased oxygen tension and impaired lymph flow in the entire lung, thus spreading tuberculosis in the lung and ultimately leading to left lung destruction.

“…It is not possible to establish the cause of hemoptysis in over 40% of the patients [106,107,108]. In western Europe and the Unites States, bronchial carcinoma, chronic inflammatory lung disease, bronchiectasis and idiopathic hemoptysis are the most frequent identifiable causes [95,109,110,111], and tuberculosis continues to be the most important cause in Third World countries [96,112,113].…”

Respiratory problems are an important issue in the palliative care setting, not only from a diagnostic and therapeutic point of view but also from emotion-related aspects involving both the patients and their families and also caregivers. In this paper we consider some of the most common respiratory problems, such as dyspnea, infections, hemoptysis, hiccup. A review of the literature was performed with reference to the frequency, diagnosis and management of the above respiratory problems in patients in advanced and terminal stages of the disease. Particular emphasis was given to the importance of communication with the patients and their families, which is considered a crucial point in the care and the cure of such patients.

“…Pulmonary tuberculosis is not a disease in which such anastomoses invariably develop, Circulation, Volume XXIII, March 1961 and again our observations are consistent with the known morbid anatomy. 19 It remains to consider the relationship of these observations to the value of pulmonary blood flow provided by the Fick calculation. A formal treatment of this relation has been published previously.32 In brief, the normal pulmonary circulation can be represented by the schema shown in figure 6, and the relation between the three streams of oxygen may be expressed as shown below: Vo2 = Q C -Q (1) where .…”

Estimation of Flow Through Bronchial-Pulmonary Vascular Anastomoses with Use of T-1824 Dye

et al. 1961

A dye-dilution method devised to estimate the individual outputs of the ventricles has been used to assess the magnitude of the flow through bronchial-pulmonary anastomoses in patients with chronic lung disease. In 10 normal subjects the output of the left ventricle was, on the average, 0.9 per cent larger than the output of the right. In six patients with advanced pulmonary tuberculosis, the average value was 2.9 per cent, and in 11 patients with bronchiectasis 9.3 per cent. One patient, who had had her left main pulmonary artery ligated, exhibited an anastomotic flow of 20 per cent. In all groups the flow calculated from the Fick equation agreed within 20 per cent with that from the right ventricle. In the normal subjects and the patients with tuberculosis, the same general agreement between the Fick and the left ventricular output was observed. But in the patients with bronchiectasis and the woman with the ligated pulmonary artery, the Fick calculation underestimated the left ventricular output. This underestimation suggests that the blood traversing the bronchial-pulmonary anastomoses had an oxygen content approximating that in the systemic arterial blood.
