Abstract
The study was conducted at department of radiology, Mansoura university hospitals aiming to reveal the effectiveness and reliability of preoperative, curative and palliative embolization of benign and malignant bone and other musculoskeletal soft tissue tumors. The type of the present study was a cross sectional study as regards definitive, palliative and pre-biopsy cases and a randomized-control study as regards the pre-operative embolization. It included 33 patients collected consecutively with vascular bone tumors diagnosed by clinical examination and were confirmed by different imaging modalities. Embolization was done in all patients, including pre-operative embolization: to decrease blood loss, definitive treatment in benign lesions located in surgically inaccessible site, pre-biopsy embolization to smoothen the procedure and decrease unplanned blood loss and palliative treatment option to decrease unplanned blood loss. Pre-procedural pathological examination was available in all patients except those who were referred for pre-biopsy embolization; in the latter trans-arterial embolization might repeated after the pathological examination by surgical biopsy. Post-procedural assessment by post-embolization angiography (on table) in all patients and either by surgical details, CT angiography or clinical follow up. This study revealed the following technical results; as regards, pre-operative trans-arterial embolization (TAE) group, 80 % cases (12 in number) showed technical success while the remaining 20 % of cases showed no technical success (3 %). As regards, TAE as a definitive treatment group, all cases (6 in number) showed technical success (100 %). As regards, Pre-biopsy TAE group, all cases (6 in number) showed technical success (100 %). As regards, TAE as a palliative treatment group, all cases (6 in number) showed technical success (100 %). As regards, Assessment of clinical success according to TAE indication, in pre-operative group by comparing between (bony lesions in this group which underwent TAE before operation) and (another similar bony lesions underwent operation without preoperative embolization) as regards mean diameter, peri-operative blood loss and units of blood transfusion needed. The mean tumor diameter did not differ significantly between the two groups (p = 0.924). Although less intra-operative blood loss was observed after embolization 840 ml vs. 1080 ml without embolization. That difference was not statistically significant between the two groups (p = 0.133). Consequently, intraoperative blood transfusion did not differ between the operative groups.
