A case of bilateral persistent sciatic artery (PSA) aneurysms with thromboembolic complications is presented along with a review of the 167 cases of PSA reported in the world literature. Its embryology, anatomy, clinical features, diagnosis, and treatment are reviewed and provide the following findings: The incidence of PSA is estimated to be from 0.025% to 0.04%, based on angiographic studies. Ages range from 6 months to 89 years, with a mean of 54 years. There is no gender predilection. A PSA was present on the right side in 32%, on the left side in 29%, bilaterally in 22%, and on either side in 18%. The "complete" type of PSA was 69%. Aneurysmal change was present in 46% of all PSAs. Overall, 59% had symptoms, including ischemia in 31% (acute in 14% and chronic in 17%), a gluteal mass in 26% (painful in 10%, painless in 6%, and pulsatile in 13%), gluteal pain in 2%, and ischialgia in 5%. Exclusion of the aneurysm or PSA by surgical or interventional techniques, with a femorodistal bypass as required for the resultant ischemia is currently the treatment of choice.
We describe herein our new method for transecting the pancreas and closing its stump in distal pancreatectomy, devised to decrease the risk of pancreatic fistula formation. With this technique, the pancreas is transected in such a way that a convex stump is left, whereby the pancreatic secretions from the parenchyma near the pancreatic stump are fully drained into the main pancreatic duct. A pedicled seromuscular flap of the stomach or jejunum is then used to cover the cut surface of the pancreas. This new technique provides tight closure of the pancreatic stump after distal pancreatectomy.
A technique for reducing the morbidity and mortality of pancreatoduodenectomy by using an omental flap to protect the anastomoses and splanchnic vessels exposed during dissection is described herein.
Tuberculous aneurysm of the aorta is an extremely rare disease with a high mortality rate. Only 32 patients treated surgically have been reported in the literature. These reports indicate an 84.4% operative survival rate. We present a case of a tuberculous false aneurysm in the descending thoracic aorta that was successfully treated surgically with an extracorporeal circulation. The hole in the aorta within the false aneurysm was closed with a Dacron patch because the aortic wall appeared to be free of active infection as a result of long-term preoperative antituberculous chemotherapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
