Cardiosurgery - Skopje Usefulness of 64 –detector-row scanner peripheral angiography in patients with skeletal tumors of lower extremities Special Hospital for surgical diseases “Filip II”Skopje - Macedonia Bozinovska B., Veljanovska L., Atanasov Z., Dimova.A. Zafirovski. G, Mitrev Z May 2009

Cardiosurgery - Skopje Technical principals of CT scanning -multiple detector array simultaneously obtains tomography data at different slice locations. - detailed analysis of anatomy and pathology. -capability of rapidly scanning large longitudinal volume of patient (torax-abdomen-both legs 20 sec.)

Cardiosurgery - Skopje CT Angiography 3D Imaging and analysis of adjacent structures (bones, muscles) and blood vessels Use of Ultravist mm with automatic injector. Scanning time 28 s.

Cardiosurgery - Skopje 64 CT ANGIOGRAPHY Non invasive procedure, comfortable for the patient Non invasive procedure, comfortable for the patient Great spatial and temporal resolution, slice thickness - 0,625 mm (provide excellent details that allow identification of vascular anomalies and different pathological entities) Great spatial and temporal resolution, slice thickness - 0,625 mm (provide excellent details that allow identification of vascular anomalies and different pathological entities) 3D post-processing 3D post-processing Method of choice for emergency cases Method of choice for emergency cases(dissection,trauma)

Cardiosurgery - Skopje CT ANGIOGRAPHY- INDICATIONS Vascular anomalies Vascular anomalies Trauma-rupture, stenosis, occlusion Trauma-rupture, stenosis, occlusion Pathological vascularisation of the tumors Pathological vascularisation of the tumors Aneurysmatic disease and dissection of the aorta Aneurysmatic disease and dissection of the aorta Aneurysmatical disease of intracranial vessels Aneurysmatical disease of intracranial vessels Planning - interventions, stenting or vascular surgery Planning - interventions, stenting or vascular surgery Post-interventional follow up (grafts, stents) Post-interventional follow up (grafts, stents)

Cardiosurgery - Skopje CT Angiography 64 detector-row scanners has brought major advantages in bone and joint imaging emphasizing its efficiency due to fast scanning and presentation of blood vessels and bone structures in assessment of skeletal malignant tumors. 64 detector-row scanners has brought major advantages in bone and joint imaging emphasizing its efficiency due to fast scanning and presentation of blood vessels and bone structures in assessment of skeletal malignant tumors.

Cardiosurgery - Skopje Goal of the study is to demonstrate usefulness of the method in diagnosis of soft tissue tumors considering location, orientation with great vessels, pathologic vascularisation and relation with the adjacent structures in order to develop further treatment. s

Cardiosurgery - Skopje We evaluated 12 patients, 5 female and 7 male age 32 to 74 years old, with skeletal malignant tumors localized in lower extremities.

Cardiosurgery - Skopje In patients with liposarcomas localized in postero-lateral femoral regions 64 MDCT has shown size and localization of the tumor with capsule, surface vessels and close relation of the tumor with superficial femoral artery. The main supply artery of tumors arises from profound femoral artery.

Cardiosurgery - Skopje In patients with malignant giant cell tumors localized in the feed, destruction of the bone was detected with infiltration of soft tissue and vessels – a.tibialis anterior, a.fibularis and a.tibialis posterior. Relation with the great vessels was very clear presented especially if the artery is compressed or infiltrated.

Cardiosurgery - Skopje Paraoseal osteosarcoma Pathologic vascularization Relation of tumor with the bone Affection of the bone Soft tissue spreading MDCT findings present affection of bone structures in patients with paraoseal osteosarcoma localized in proximal-lateral tibia region and pathologic vascularization of the tumor with main supply artery of the tumor arising from popliteal artery.

Cardiosurgery - Skopje Conclusion: According to histopathology results 5 of the patients were with diagnosed liposarcoma, 3 malignant giant cell tumors and 4 with paraosseal osteosarcoma. According to histopathology results 5 of the patients were with diagnosed liposarcoma, 3 malignant giant cell tumors and 4 with paraosseal osteosarcoma. 64 slice MDCT peripheral angiography has high diagnostic accuracy in presentation of skeletal tumors and relation, localization toward great vessels.It gives opportunity for embolization of the main feeding artery of the tumor and less bleeding operative treatment. 64 slice MDCT peripheral angiography has high diagnostic accuracy in presentation of skeletal tumors and relation, localization toward great vessels.It gives opportunity for embolization of the main feeding artery of the tumor and less bleeding operative treatment.
