Development of the respiratory system begins at 3 weeks gestation, and aberrations in the developmental processes may give rise to a group of structural abnormalities collectively referred to as bronchopulmonary foregut malformations (BPFMs). The common BPFMs include congenital cystic adenomatoid malformation (CCAM), pulmonary sequestration, congenital lobar emphysema, and bronchogenic cysts (B...

Systemic arterialization of the lung without pulmonary sequestration is the rarest form of anomalous systemic arterial supply to the lung. This condition is characterised by an aberrant arterial branch arising from the aorta which supplies an area of lung parenchyma with normal bronchopulmonary anatomy. It is often diagnosed following investigation of an incidental cardiac murmur or based on ab...

In this article, we report a rare case of a 22-year-old male with bilateral pulmonary sequestration, treated with embolization and surgical resection. The initial plan involved staged bilateral lobectomy for both lungs and prophylactic embolization of feeding vessels for preventing unexpected hemorrhage during operation. Symptomatic right lower lobe was resected with video-assisted thoracic sur...

This paper reports four cases of a broncho-pulmonary mass, supplied by an aberrant artery, occurring in the lower lobe of the lung. The object in presenting these cases is twofold; to draw attention to the diversity of the radiological picture and to discuss the effect of the systemic aberrant vessel on the production of the condition. Details of 43 cases reported since 1948, relevant to any as...

An index of pulmonary epithelial permeability has been studied in 12 patients with chronic renal failure during haemodialysis. It was assessed by the half time clearance from lung to blood (t 1/2 LB) of a nebulised solution containing technetium labelled diethylene triamine pentacetic acid (99mTc DTPA). Six patients were cigarette smokers and six were non-smokers. The non-smokers had greater pr...

The authors report on a newborn boy with extralobar pulmonary sequestration in the right upper thoracic region. Preoperative angiography showed an anomalous large vessel from the right subclavian artery, supplying the sequestrated lobe. Right thoracotomy was performed to resect the sequestrated lobe, which was diagnosed as extralobar form. This is an extremely rare case of extralobar pulmonary ...

Lolium perenne L. spp. multiflorum (Lam.) Husnot (LOLMU) is a winter annual weed, common to row crops, orchards and roadsides. Glyphosate-resistant populations of LOLMU are widespread in California. In many situations, growers have switched to paraquat or other postemergence herbicides to manage glyphosate-resistant LOLMU populations. Recently, poor control of LOLMU with paraquat was reported i...

Intralobar pulmonary sequestration is a rare congenital malformation characterized by the presence of nonfunctional parenchymal lung tissue, receiving systemic arterial blood supply and lacking normal communication with tracheobronchial tree. Recurrent pneumonia and massive hemoptysis are life threatening complications associated with it. Delay in the diagnosis and management can be fatal. We r...
