Tranexamic acid as a novel adjunct in the management of vessel perforation complicating Endovascular Clot Retrieval.

AIM: To assess the safety and utility of tranexamic acid (TXA) as an adjunct salvage therapy in iatrogenic vessel perforation complicating endovascular clot retrieval. Iatrogenic vessel perforation and extravasation are known and potentially fatal complications of endovascular clot retrieval (ECR). Various methods of establishing haemostasis post perforation have been reported. TXA is widely utilised intraoperatively to reduce bleeding in various surgical specialities. The use of TXA in endovascular procedures has not been previously described in the literature. METHODS: Retrospective case control study of all cases that underwent ECR. Cases where arterial rupture occurred were identified. Details of management and functional status at 3 months were recorded. Modified Rankin score (mRS) 0-2 was considered a good functional outcome. Comparison of proportions analysis was performed. RESULTS: Of 1378 cases of ECR, rupture complicated 36 (2.6%). TXA was administered in addition to standard care in 11 cases (31%). At 3 months, 4 of 11 cases (36%) where TXA was administered had a good functional outcome compared to 3 of 22 (12%) in the standard care group (P=0.09). Mortality at 3 months occurred in 4 of 11 cases (41.7%) where TXA was administered compared to 16 of 25 (64%) where it was not (P=0.13). CONCLUSION: Tranexamic acid administration in iatrogenic vessel rupture was associated with a lower mortality rate and a larger proportion of patients achieving a good functional outcome at 3 months. This effect trended towards but was not statistically significant. TXA administration was not associated with adverse effects.

Bladder leiomyoma and the utility of 18F-Fluorodeoxyglucose-Positron Emission Tomography - a Case Report.

Bladder leiomyomas are rare neoplasms and various diagnostic methods are available to assist in confirming diagnosis preoperatively. Presented here is a case of bladder leiomyoma in a 41-year-old female who presented with urinary symptoms and right thigh pain. Imaging revealed a soft tissue density mass in the bladder wall. However concerns of a leiomyosarcoma remained. An 18F-fluorodeoxyglucose (FDG) positron emission tomography/computerized tomography (PET/CT) demonstrated low FDG uptake and absence of metastatic lesions. In combination with operative findings, the tumor allowed for localized resection instead of more invasive partial cystectomy. Therefore, FDG-PET might be used to support the diagnosis of leiomyoma and potentially facilitate a less aggressive surgical management.
