Pseudoaneurysm of the right ventricular outflow tract after homograft placement is an infrequent complication after intracardiac repair for tetralogy of Fallot. We report two cases of pseudoaneurysm of right ventricular outflow tract after homograft placement for surgical repair of tetralogy of Fallot with pulmonary atresia.

There is rising evidence that anemia and blood transfusion increase perioperative mortality in cancer patients. Patients who are treated with neoadjuvant chemotherapy with a curative intent are exposed to toxicity that may negatively affect their future outcome. ⋯ Preoperative chemotherapy for locally advanced esophagogastric cancer induces anemia and therefore leads to preoperative blood supplementation in a considerable number of patients. Data indicate that this may counteract the beneficial effects of neoadjuvant treatment.

Clinical Trial
The accuracy of integrated PET-CT compared with dedicated PET alone for the staging of patients with nonsmall cell lung cancer.
The treatment of patients with nonsmall cell lung cancer (NSCLC) is determined by the stage. We evaluated the accuracy of staging using integrated positron emission tomography (PET) and computed tomography (CT) and compared it with dedicated PET visually correlated with CT scan. ⋯ Integrated PET-CT using FDG-18 better predicts stage I and II disease as well as the T and N status of patients with NSCLC when compared with dedicated PET alone. It is more accurate at some nodal stations but still only achieves an accuracy of 96% and 90% for the N2 and N1 nodes, respectively.

Pulmonary embolectomy is an evolving surgical procedure for the treatment of severe pulmonary embolism. In addition to removing pulmonary thromboemboli, the achievement of optimal results also requires identification and extraction of intrathoracic, extrapulmonary thromboemboli from the right atrium, right ventricle, and the superior or inferior vena cava. Otherwise, these thromboemboli may become the source of recurrent pulmonary embolism. Intraoperative transesophageal echocardiography is frequently used during pulmonary embolectomy as a guide for the surgeon and a monitor of cardiac performance. However, its utility for detecting concurrent intrathoracic, extrapulmonary thromboemboli has not been thoroughly investigated. ⋯ Intraoperative transesophageal echocardiography identified intrathoracic, extrapulmonary thomboemboli in 26% of patients undergoing pulmonary embolectomy, resulting in an alteration of surgical management in 10% of patients. These findings support the critical role of intraoperative echocardiography during pulmonary embolectomy.

Comparative Study
Selective division of T3 rami communicantes (T3 ramicotomy) in the treatment of palmar hyperhidrosis.
Compensatory sweating (CS) is the main cause of a patient's dissatisfaction after sympathetic surgery for palmar hyperhidrosis. Preservation of the sympathetic nerve trunk and limitations on the range of dissection are necessary to reduce CS. ⋯ The incidence of sweating postoperatively was relatively high in the T3 ramicotomy group, although the T3 surgery did result in a lower incidence of CS when compared with a T2 sympathicotomy.
