Successful Endoscopic Repair of Postoperative Ileocecal Intussusception in An Adult

Postoperative ileocecal intussusception is a rare complication in adult patients with abdominal aortic repair. A 63-year-old male patient with an abdominal aortic aneurysm was admitted to our hospital for abdominal aortic replacement. On the third postoperative day, he had nausea, vomiting, and distention. An abdominal x-ray showed air-fluid levels. His condition improved after 72 h of conservative treatment with long-tube suction for decompression. On the sixth postoperative day, he had acute abdominal pain. A computed tomography scan showed the typical intussusception picture. A diagnostic and therapeutic endoscopy were performed. An ileocecal intussusception 20 cm proximal to the ileocecal valve was found and endoscopically reduced. [Arch Clin Exp Surg 2013; 2(3.000): 204-206

Iatrogenic Tamponade Induced by Torn Catheter Sheath

A 64-year-old man underwent ablation for atrioventricular node reentry tachycardia. After 1 month, he presented to the emergency room with increasing dyspnea, chest pain, and shock secondary to cardiac tamponade. Contrast-enhanced computed tomography showed a foreign body in the right ventricle, with significant pericardial effusions. He underwent emergency cardiac surgery for removing the foreign body. It was identified as a torn catheter sheath. [Arch Clin Exp Surg 2014; 3(2.000): 115-117

Surgical Reconstruction for Coarctation of the Abdominal Aorta

A 28-year-old man was referred for hypertension of 160/92 mmHg that was poorly controlled medically. However, he had no signs of lower limb ischemia; he had diminished femoral pulses and ankle-brachial indices of 0.7 bilaterally on physical examination. Computed tomography revealed coarctation of the abdominal aorta, beginning just below the takeoff of both renal arteries and extending above the inferior mesenteric artery. A 14-mm woven dacron aorto-aortic bypass, sutured end-to-side to the proximal descending thoracic aorta above and to the infrarenal abdominal aorta below, as well as right renal artery reconstruction were performed. The postoperative course was uneventful and he continues to have normal blood pressure and normal femoral pulses. [Arch Clin Exp Surg 2012; 1(4.000): 265-269

Pannus-Related Mechanical Valve Dysfunction Leading to Hemodynamic Shock

Mechanical prosthetic valve dysfunction caused by pannus formation is rare. Pannus restricts movement of prosthetic valve leaflets, resulting in severe aortic regurgitation. We describe the case of a 77-year-old woman who presented to the emergency room with increasing dyspnea, ischemia, and shock secondary to mechanical aortic valve dysfunction. Transesophageal echocardiography showed a blockade of the leaflets of the mechanical aortic valve, with severe aortic regurgitation. She underwent emergent cardiac surgery for aortic valve replacement. Pannus formation should be considered as a potential cause of acute severe aortic regurgitation in a patient with a small-sized mechanical aortic prosthesis in the supra-annular position. On a pathological exam, extensive pannus was found on the ventricular side of the prosthetic valve, extending from the ring into the central orifice. [Arch Clin Exp Surg 2012; 1(1.000): 50-53
