A case of solitary fibrous tumor in the pelvis presenting massive hemorrhage during surgery

Abstract

Solitary fibrous tumors (SFTs) are unique soft-tissue tumors of submesothelial origin. These tumors are mainly located in the pleural space but they can be originated within a variety of sites, including the abdomen, the pelvis, the soft tissues and the retroperitoneum. SFTs from all sites are usually benign, and the surgical resection is curative in almost all cases. According to the review of literatures, during the surgical resection, massive hemorrhage could occur due to the hypervascular nature of SFTs. This is a case report on SFT in the pelvis presenting great vessel injury, which resulted in life threatening hemorrhage during the resection of tumor. We wish this paper alerts gynecologists about the risk of massive bleeding during the resection of tumor located at adjacent to great vessels in the pelvis.

Successful Treatment of a Solitary Fibrous Tumor in the Small Pelvis: A Case Report

“…Выполнение предоперационной эмболизации питающих сосудов нашло свое применение при СФО грудной полости, шеи и позвоночника [35][36][37], однако в литературе недостаточно данных об использовании данной процедуры при опухолях, расположенных в малом тазу. При этом выполнение оперативных вмешательств при гигантских СФО малого таза сопряжено с риском кровотечения, а в ряде наблюдений приводило к летальным исходам от геморрагического шока [38,39]. В нашем случае при ангиографии выявлена гиперваскуляризированная опухоль, которая кровоснабжалась преимущественно из задних ветвей внутренних подвздошных артерий (больше справа), в связи с этим была произведена эмболизация питающих артерий, целью которой было уменьшить размеры опухоли и избежать массивного интраоперационного кровотечения.…”

Giant solitary fibrous tumor of the pelvis successfully treated with preoperative embolization and surgical resection: a case report

“…The resection of giant pelvic tumors, even if they are benign, is usually complicated by difficulties in visualizing the operative field, and the resection of giant pelvic hypervascular tumors such as SFTs is sometimes very dangerous. Indeed, a massive transfusion was needed in several cases of abdominopelvic SFT resection, and in two cases, patients died postoperatively of hemorrhagic shock [ 18 , 19 ]. In our case, angiography revealed a hypervascular tumor that was fed by branches of the left internal iliac artery.…”

Integrally calcified solitary fibrous tumor in the retroperitoneum: a case report and review of the literature

“…SFT can cause local pressure syndrome [ 9 ] and some reports described that SFT presented hypoglycemia due to the insulin-like growth factor II secretion from the tumor [ 10 , 11 ]. In imaging studies, SFT typically presents well-defined and lobulated mass with well-enhancement [ 9 ].…”
