The Urology Department of Fondazione IRCCS Policlinico San Matteo requested 3D4Med support for the production of two 3D printed models for surgicalplanning and anatomical comprehension. Both clinical cases regard patients referred to Fondazione IRCCS Policlinico San Matteo for kidney cancer. Patients underwent a kidney tumors' enucleation procedure and the 3D printed models were used to better understand the tumors' positioning and degree of infiltration.
A 65-years old athlete referred to Fondazione IRCCS Policlinico San Matteo after cardiac arrest, presenting with a rare right coronary anomaly (right coronary artery ostium atresia) and no other causes of sudden cardiac death. A 3D Virtual model has been reconstructed from CT scan through image segmentation techniques. In CT imaging, the use of contrast medium highlights the blood flowing inside vessels, while their wall remains mostly invisible...
The team of Dr. Pelenghi, director of Cardiac Surgery Unit at Fondazione IRCCS Policlinico San Matteo (Pavia), performed the world’s first “beating heart” surgical implant of an innovative pulmonary valve prosthesis on an over 50 years old patient, suffering from idiopathic pulmonary arterial hypertension. The surgical strategy was planned on the virtual and 3D printed anatomical model of the affected district, realized by the 3D printing clinical laboratory "3D4Med".
The patient-specific anatomical model is a 3D printed reconstruction in deformable material of the left atrium with a “chicken wing” appendage.
The patient-specific model represents the pancreatic-duodenal tract with its arterial and venous vessels.
Patient-specific model of a spinal column with an evident scoliosis. The 3D printed model has been useful to evaluate the pathological curvature of the spine and to plan the surgical treatment involving modeling and placement of metal bars to straighten the spinal column.
The patient-specific model is a 3D printed reconstruction of an aneurysm of the abdominal aorta. The model has been useful for the pre-operative evaluation of the aneurysm (shape, dimension and location) and for the surgical planning of aneurysm resection and endo-prosthesis selection and placement.
The 3D printed model includes the pelvic bone structure (white) the tumor (black and purple) and the surrounding venous (blue) and arterial (red) vessels.
