BACKGROUND There is considerable controversy about the arterial supply to the superior parathyroid glands. Knowledge of this blood supply should be important for the surgeon performing thyroid and parathyroid operations. The purpose of this investigation was to document whether the superior parathyroid glands receive their blood supply from the superior(More)
This report examines the charcteristics of 10 patients surgically treated for unequivocal parathyroid carcinoma. Seven cases were from our series of 165 patients with primary hyperparathyroidism. Routine determination of serum calcium level by an automated analyzer occasionally led to early tumor detection. A spectrum of clinical and pathological variation(More)
The secondary aortoenteric fistula (AEF) is a rare but grave complication of aortic reconstructive surgery. We report herein a case of an aortocolic fistula which occurred 27 years after an aortofemoral bypass. A 69-year-old man was admitted to hospital following a sudden episode of melena. He had undergone aortofemoral bypass surgery with a prosthetic(More)
Six cases of recurrent parathyroid carcinoma were reviewed. Four patients presented with local recurrence, which followed a simple tumor resection more frequently than an en bloc initial operation. The fact that the mode of recurrence varied made preoperative localization difficult. In 3 earlier patients (1978–1980), careful palpation of the neck and venous(More)
BACKGROUND Less extensive resection of the head of the pancreas has been the procedure of choice recently for low-grade malignant neoplasms. The anatomical detail of the head of the pancreas is currently insufficient for segmental resection along the embryological fusion plane. METHODS The anatomy of the head of the pancreas was analyzed in 31 consecutive(More)
Tracheo-innominate artery fistula is a highly lethal complication after tracheostomy. A 37-year-old man who had undergone a tracheostomy 14 years earlier because of dysphagia after brain surgery had a tracheo-innominate artery fistula with exsanguinating hemorrhage from his tracheostomy site. After temporary control of the bleeding, a stent graft was(More)
We report a case of primary amyloidosis with repeated bowel perforations. This patient also had localized amyloid deposition creating a tumorous region mimicking malignancy in the rectum. Perforation of the intestine is common in systemic amyloidosis. The ischemic change due to amyloid infiltration into the vessel wall may lead to perforation of the(More)
A rare case of autopsy-proven recurrence 10 years after a radical resection for lower bile duct carcinoma is herein reported. The subject is a 53-year-old man who underwent a curative resection of distal bile duct carcinoma with pancreatoduodenectomy in 1981. The lesion was a 1.0 X 1.5 X 1.0 cm well-differentiated papillotubular adenocarcinoma invading the(More)
