Since bronchography is helpful in certain clinical settings, we describe a simplified method for performing selective bronchography in conjunction with fiberoptic bronchoscopy. Selected cases are presented which illustrate that this technique is easily performed, has minimal risk, and produces bronchograms of high quality. _Br.!Ln~hQgr:apJ1Y, ~!~nti.Y9Jy_~'!f.c_nr.Q..c;Q~l u r!;l_ f.Qt:'-Cy.lll llllting

In the fluoroscopic suite, fiberoptic bronchoscopy is performed in the usual manner. The segment of the lung to be evaluated is localized, and the bronchoscope is modified as follows. The outer protective sheath from a Microbiology Specimen Brush (Medi- Tech) is advanced through the aspirating channel of the bronchoscope until it extends just beyond the tip of the bronchoscope into the localized segment. A I6-gauge needle, 3.4 em long, is snugly fitted into the proximal end of the protective sheath (Fig 1). Smaller gauge needles or sheaths have not proven effective for the instillation of contrast material. This modification protects the bronchoscope from direct contact with the contrast material, Dionosil (a solution of organically bound iodine in peanut oil). The contrast material is prewarmed to 37°C in a water bath. It is diluted to a maximum of a 50:50 mixture with isotonic saline, stirred vigorously, drawn up into a 20-ml syringe, and directly instilled through the needle and sheath.

In order to limit th e am ount of contrast material used, ye t obtain hi gh-quality ana tom ic d etail, several techniques for bronch oscopy combined with sel ective bronchography have been proposed. In one method, after ro u tine flexibl e fiberoptic bronchoscopy is performed, the bronchoscope is us ed as a laryngoscope to guide a soft catheter through the vocal cords. " The bronchoscope is withdrawn, and prior to in stilling the contrast material, the catheter is fluoroscopically guided in to the se gme n t to be examined. Another m ethod e mp loys a modified Seldinger technique wherein a guide wire is p assed through the aspirating channel of the bronchosco pe into the seg men t to b e evaluated." The bronch oscope is withdrawn over the firmly held guide wire . A cathete r is advanced in to po sition over the wire , and th e guide wire is th en rem oved. Proper po sition is assess ed, and the contrast material is instilled with th e aid of fluoro scopy. More recently, direct instillation of contrast material through the aspirating channel of the bronchoscope has been advocated ." The ad van tages of bronchoscopy co mbine d with se lec tive b ron chography have been previou sly d escribed. Pati ents d o not have to undergo th e discomfort, p otential morbidity, and expense of two se para te procedure s.'

A 22-year-old man suffered a basilar skull fracture and loss of consciousness as a result of a motorcycle accide nt. He developed an empyema secondary to aspiration pne umonia. After parent eral treatment with antibiotics had failed, he underwent thoracotomy with open drainage. Prior to chest wall reconstru ction, a fistulagram was performed in order to ascertain the presence ofa bronchopleu ral fistula, but the stud y was technically limited and nondiagnostic. Bronchoscopy with selective right middle and lower lobe bronchography showed no evidence of a fistula. CASE

A20-year-old woman had been well until the age of12years, when she developed recurrent bronchitis. A chest x-ray film at that time showed a left upper lobar density. Bronchoscopy wasnondiagnostic, and subsequent x-ray films showed resolution of the density. At th e age of19 years, the patient developed cough and fever, and an x-ray film showed reappearance of the left upp er lobe density. Treatment with antibiotics resulted in partial clearing of this density, and bronchoscopy was again nondiagnostic, The patient was referr ed to our medical facility for further evaluation. Her chest roentgenogram showed a left upp er lobe density without interval change from the evaluation six months earlier (Fig 3). A comput erized tomographic scan suggested bronchiectasis and confirmed the presence of a homogeneous density in the left upper lobe. A complete blood cell count, quantitative assay of immunoglobulins, and sweat chloride levels were normal. Bronchoscopy combined with selective bronchography showed dilatation of bronchi, with a normal pattern of arborization. The bronchi circumvented the density, which did not fill with contrast material (Fig 4). At thoracotomy, performed for recurr ent infection, a mucus-filled bronchogenic cyst was removed with an apical segment ectomy.

CASE REPORT

A26-year-old man wasadmitted on April 5, 1985, following a highspeed deceleration injury, Initial evaluation revealed a contusion over the sternum, distended veins in the neck with prominent v waves, a right vent ricular S3 and S. gallop, and palpable v waves over the liver, There was no accompanying murmur, The peak level ofcreatine phosphokinase (CPK)was1,300IU, and a weaklypositive fluorescent MB band was present. The initial chest x-ray film was within normal limits. The electrocardiogram showed transient right bundle-branch block and multifocal premature ventricular contractions which suggested the possibility of myocardial contusion. An echocardiogram demonstrated a hyperdynamic right ventricle with paradoxic septal motion, flail tricuspid leaflets, and an echolucency consistent with a hematoma in the basilar portion of the septum . On April 8, 1985, the patient developed mild chest pain associated with tachypnea and hypotension. A loud pericardial friction rub was now audible. Right cardiac catheterization showed no evidence of a left-to-right shunt.
