The patient in this case was a 38-year-old male who presented with tachypnea and dyspnea, cyanosis of extremities, and significant digital clubbing. The patient had structural epilepsy secondary to neurosurgery for a cerebral abscess during childhood. Arterial blood gas analysis showed significant hypoxemia (PaO₂ = 46.2; SaO₂ = 77%; PaO₂/FiO₂ = 70) and a chest computed tomography showed PAVM in the apical segments of the right upper and lower lobes, with ectatic and tortuous vascular structures following an intraparenchymal path, communicating with the pulmonary artery and veins. After confirmation of the PAVM, it was concluded that elevated pulmonary resistance was contributing to refractive hypoxemia and hypercapnia. Gradual reduction of the ventilation parameters, primarily controlled pressure and positive end-expiratory pressure, and consequent reduction of the arteriovenous shunt, resulted in progressive improvement of oxygenation and respiratory mechanics.

In this article, a case is reported on the hepatic metastasectomy approach in a 47-year-old female patient, with colon adenocarcinoma who underwent vascular reconstruction in the same surgical procedure. The intrahepatic mass was transposition of the gastroduodenal artery through the anastomosis of the gastroduodenal artery and the right hepatic artery in a continuous suture, without complications. It is concluded that vascular anastomosis in hepatectomies for colon adenocarcinoma metastases is a complex procedure that requires skill and experience from the surgeon.
