Primary Leiomyosarcoma

Purpose: To report stent implantation for a malignant obstruction within the pulmonary artery (PA) caused by a recurrent leiomyosarcoma in the pulmonary trunk. Case Report: A 62-year-old man with a non-metastatic primary leiomyosarcoma of the right PA underwent pneumectomy of the right lung and postoperative radiotherapy in 1994. Six years later, he presented with symptoms of progressive right ventricular dysfunction. Computed tomography (CT) identified a high-grade stenosis of the left PA due to recurrent tumor within the pulmonary trunk extending into the left PA. Transthoracic ultrasound documented severe pulmonary hypertension with a high pressure gradient across the stenosis. A stent was deployed percutaneously, successfully establishing PA patency. Pressure measurements showed a significantly reduced gradient across the stented area. In follow-up, the patient reported subjective improvement of symptoms; CT scans revealed a fully patent stent. His status remained stable 11 months after stent implantation. Conclusions: PA leiomyosarcoma is a rare and highly malignant tumor. In most cases, surgery can only prolong survival for the short term. Palliative interventional PA stenting performed under local anesthesia can offer improvement in quality of life by reducing excessive pulmonary hypertension.

Multiple Recurrences

AbstractPatients with Williams syndrome often present with abnormalities of the vascular wall of the aorta and/or the pulmonary artery. Surgery may result in restenosis of the affected vessel. Herein, we report a case of an infant with multiple recurrences of aortic coarctation successfully treated with Zotarolimus drug-eluting stent.
