Histochemical alterations in one lung ventilation.

Background: One lung ventilation is a commonly performed surgical procedure. Although there have been several reports showing that one-lung ventilation can cause pathophysiological alterations such as pulmonary hypoxic vasoconstriction and intrapulmonary shunting, there have been virtually no reports on the effects of one-lung ventilation on lung histology.

Materials And Methods: Yorkshire pigs (11-17 kg) were anesthetized, a tracheotomy performed and a tracheal tube inserted.

An alternative approach: antegrade catheter-directed thrombolysis in a case of phlegmasia cerulea dolens.

Phlegmasia cerulea dolens is an uncommon sequela of severe deep venous thrombosis of the lower extremities. Characterized by massive edema, arterial and venous compromise, and threats to limb and life, this clinical entity is a clear indication for thrombolytic therapy. We report an innovative approach to conventional thrombolysis via a lesser saphenous vein cut-down.

The wandering coronary stent. Case report.

Complications associated with coronary stent placement have decreased in recent years. One of the complications involved with this procedure is the possibility that the stent is stripped from the delivery catheter prior to deployment and is lost systemically. This paper reports a rare complication which resulted in vascular insufficiency necessitating surgical intervention.

Lung volume reduction surgery in ventilator-dependent COPD patients.

Background: Lung volume reduction surgery has been advocated recently as adjunctive surgical therapy to improve lung and chest wall mechanics in selected patients with diffuse emphysema. Although clear-cut guidelines to select candidates have not been fully established, patients decompensated with significant pulmonary artery hypertension and hypercapnic respiratory failure are currently not considered suitable subjects. Accordingly, ventilator-dependent COPD patients are not considered candidates for this procedure.

Chest wall metastasis after percutaneous fine-needle aspiration biopsy.

Presented is a case of a chest wall metastasis due to tumor seeding along the needle tract from a percutaneous fine-needle aspiration biopsy (FNAB) of a lung carcinoma. At thoracostomy, the patient was found to have a chest wall lesion at the site of the FNAB that had been performed 4 months earlier. This relatively uncommon complication has been reported elsewhere, but its significance with respect to the management of lung lesions suspected to be malignant has not been defined.
