Intravenous thrombolytic treatment of mechanical prosthetic valve thrombosis: a study using serial transesophageal echocardiography.

Objective: We analyzed the results of intravenous thrombolytic treatment under transesophageal echocardiographic (TEE) guidance in prosthetic valve thrombosis.

Background: Thrombotic occlusion of prosthetic valves continues to be an uncommon but serious complication. Intravenous thrombolytic treatment has been proposed as an alternative to surgical intervention.

Single-photon emission computed tomographic myocardial perfusion imaging in patients with mitral valve prolapse.

The possibility of exercise-induced myocardial ischemia due to mitral valve prolapse (MVP) in the absence of coronary artery disease was evaluated with single-photon emission computed tomographic analysis using thallium-201 and technetium-99m sestamibi in 72 patients with MVP. Exercise electrocardiography was positive in 5 patients (8%), but single-photon emission computed tomography was found to be normal in all patients, and exercise-induced chest pain, electrocardiographic changes, and arrhythmias were found not to be related to myocardial ischemia in patients with MVP.

Comparison of consequent small bowel anastomoses after transient ischemia: an experimental study in rats.

Background/purpose: The role of ischemia/reperfusion (I/R) damage on intestinal anastomotic healing remains to be precisely determined. The objective of this study was to investigate healing of small bowel anastomoses performed at different times after transient ischemia.

Methods: Thirty male Wistar-Albino rats were investigated in five groups (four study and one control).

Assessment of anastomotic reliability with pulse oximetry in graded intestinal ischemia: an experimental study in dogs.

Background/purpose: Pulse oximetry has been proposed as an appropriate and feasible technique in the assessment of intestinal ischemia in recent years. In this study the authors aimed to assess the reliability of anastomoses in the dog small intestine in which there is graded irreversible ischemia as measured by pulse oxymeter.

Methods: In a control group of four dogs, without any devascularization, three small bowel anastomoses were formed in each dog.

Neovascularization of the testicle through spermatic vessels by omental pedicle flap: a new experimental model.

The aim of this experimental study in rats was to consider the supplementary role of an omental pedicle flap on the neovascularization of the testicle through the spermatic vessels, for which a Fowler-Stephens procedure had been planned. To compare results, 12 animals had only the spermatic vessels ligated, without an additional procedure (Fowler-Stephens procedure [FS group]), and 12 others had omentopexy of the spermatic vessels of the left testes, with ligation of the vessels 4 weeks later (Fowler-Stephens procedure plus omentopexy [FSO group]). In the sham group (n = 8), only omentopexy of the left spermatic vessels was performed.

Hungry bone syndrome in a child following parathyroid surgery.

The rare hungry bone syndrome was encountered in a 15-year-old child after the removal of a parathyroid adenoma. Contrary to the hypocalcemias caused by the removal of all parathyroid glands or transient ischemia after parathyroid surgery, in which the serum inorganic phosphorus level is usually normal, both serum calcium and inorganic phosphorus levels are decreased in hungry bone syndrome in the early postoperative period. Vigorous calcium supplementation and vitamin D are required for prolonged periods.
