          Abstract

          The spleen is supplied by blood flow through the splenic artery and vein. The purpose of this communication is to report an ectopic spleen supplied only by reverse flow through the left gastro-omental vessels. A 14-year-old boy presented with pelvic splenomegaly supplied only by the left gastro-omental artery and veins connected to the inferior polar vessels, which were the only vessels communicating with the spleen. After detorsion of the spleen and splenopexy, the spleen returned to normal dimensions. The patient had uneventful follow-up. In conclusion, the left gastroepiploic vessels are able to maintain the entire spleen blood supply.

          Resumo

          O baço é suprido pelo fluxo sanguíneo da artéria e veia esplênicas. O objetivo desta comunicação é apresentar um baço ectópico suprido apenas pelo fluxo sanguíneo reverso proveniente dos vasos gastromentais esquerdos. Um paciente de 14 anos apresentou esplenomegalia pélvica suprida apenas por artéria e veia gastromentais esquerdas, conectadas aos vasos polares inferiores, que eram os únicos presentes nesse baço. Após a distorção do baço e a esplenopexia, o baço voltou às dimensões normais. Não houve intercorrências no acompanhamento do paciente. Em conclusão, os vasos gastromentais esquerdos são capazes de suprir o fluxo sanguíneo de todo o baço.

          Conservation of the spleen with distal pancreatectomy.

          This report describes a rapid, easy, and safe means of saving the spleen while resecting or fully mobilizing the pancreatic tail. The pancreas is separated from the spleen by dividing the splenic artery and vein distal to the tip of the pancreas. The spleen survives on the short gastric vessels, which are carefully preserved. The technique has been applied successfully in 22 of 25 consecutive patients with chronic pancreatitis (n = 13), acute pancreatitis and pancreatic necrosis (n = 3), cystic neoplasm of the pancreas (n = 4), islet cell tumor (n = 2), and ductal adenocarcinoma (n = 3). The spleen could not be saved in three patients because of splenic hilar involvement by tumor or scar. Normal postoperative blood cell counts and spleen scans proved splenic viability and function. There was only one complication, a late splenic abscess that developed in a spleen of twice-normal size. It is concluded that in most instances the distal pancreas can be mobilized for resection or inspection without the need for splenectomy. Splenomegaly may be a contraindication because the short-vessel gastric blood supply may be inadequate to nourish the increased tissue mass. The technique is applicable to the treatment of pancreatic tumors, trauma, and pancreatitis.

            Wandering Spleen: An Overview.

            An ectopic (or "wandering") spleen results from abnormal ligamentous laxity failing to fixate the spleen in its normal location in the left upper quadrant. Ligamentous laxity can be acquired due to conditions, such as splenomegaly or pregnancy, but is often congenital. Because of this laxity, there is an elongated vascular pedicle, which is prone to torsion and resultant splenic infarction. These patients generally present with abdominal pain and other nonspecific symptoms making the diagnosis very difficult to make clinically. As such, the radiologist plays a crucial role in the diagnosis and care of these patients, as often the diagnosis is only considered after imaging.
