Lymphoproliferative Disorders after Lung Transplantation: Clinicopathological Characterization of 16 Cases with Identification of Very-Late-Onset Forms.

Background: The incidence of posttransplant lymphoproliferative disorders (PTLD) has recently declined, but late cases are increasingly reported in lung transplant recipients.

Objectives: We present our experience with PTLD after lung transplantation, attempting to examine the distinguishing characteristics of early versus late cases.

Methods: We have reviewed clinical and pathological data of all cases occurring in our institution between 2001 and 2014.

[Surgical treatment of pulmonary arterial hypertension].

The most accurate treatment of obstructive pulmonary arterial hypertension (PAH) is the obstruction relief by surgery. Pulmonary endarterectomy is the treatment of choice of chronic thromboembolic pulmonary disease, the major cause of obstructive PAH. This procedure is associated with a low mortality rate in experienced centres and results in a dramatic improvement of hemodynamic parameters, functional status and survival rate.
