In situ saphenous vein grafts are being used with increasing frequency for bypass procedures involving the femoral and popliteal arteries. Complications of these procedures include anastomotic stenoses and persistent arteriovenous fistulae that may result in failure of the graft. Balloon angioplasty and embolotherapy with detachable balloons were employed successfully in three or four recent cases of patients with complications from in situ grafts. Tailored angiography is essential for evaluating in situ grafts, and interventional techniques are extremely useful for managing complications. 相似文献

Polycystic kidney disease is an autosomal dominant disease that may be associated with cystic disease of the liver. In women, the cysts may develop early and be more troublesome than in men. Cystadenocarcinoma of the pancreas is uncommon, comprising 1% of primary pancreatic malignancies. This case report is the first to describe a familial association between polycystic kidney disease and cystadenocarcinoma of the pancreas and liver in the English medical literature. A patient with autosomal dominant polycystic kidney disease (ADPKD) and multiple hepatic cysts developed cystadenocarcinoma of the pancreas with multiple malignant liver cysts. The patient's mother, sister, and niece had ADPKD, and the patient's sister also died of pancreatic cystadenocarcinoma. We believe that the development of these two disease entities in which the primary pathology is cyst formation has a genetic association. (Gastroenterology 1997 Jun;112(6):2104-7) 相似文献

The aim of the study was to evaluate endourological techniques in the management of iatrogenic ureterovaginal fistula. Seventeen
patients referred to us after gynecologic surgery were diagnosed as having iatrogenic ureterovaginal fistula. First, retrograde
double-J stenting was tried. If this failed, percutaneous nephrostomy using an antegrade double-J stent was performed. If
this also failed, open surgical repair was performed. The retrograde double-J stent bypassed the fistula in 2 patients (11.8%).
Percutaneous nephrostomy was performed in the remaining 15. The antegrade double-J stent bypassed the fistula in another 2
of these patients (11.8%). Open surgical repair was performed in the remaining 13 patients (67.5%) (direct ureteroneocystostomy)
with nipple valve in 11 patients and Boari flap with psoas hitch in 2 patients). Of all patients, 2 had ureteral stricture,
one after antegrade double-J stenting and the other after open repair. It was concluded that early intervention is recommended
in the treatment of iatrogenic uretrovaginal fistula, causing minimal morbidity and discomfort, and being less expensive.
EDITORIAL COMMENT: This is an interesting paper that is worthy of mention because of an important concept in the management
of an iatrogenic ureterovaginal fistula. The traditional management of these fistulas has been ureteroneocystostomy [1]. However,
recent urologic literature suggests that modern endoscopic treatment is highly successful if the passage of an internal stent
is possible [2,3]. This is a concept that must be shared with our urogynecologic colleagues.
In this paper, 4 of 14 patients with an iatrogenic fistula underwent placement of an indwelling stent. Of these, two were
placed cystoscopically, whereas the other two were placed percutaneously. All four ureterovaginal fistulas healed successfully.
However, 1 patient developed a ureteral stricture. It is noteworthy that in the combined series of Selzman [2] and this Tulane
group not only were all ureterovaginal fistulas successfully treated with a stent, but only 1 of 11 patients (9%) developed
a stricture.
Although the sample size is small, this paper supports the conclusion that successful endoscopic placement of a double-J stent
does allow the ureterovaginal fistula to heal spontaneously. Therefore, initial endoscopic management of an iatrogenic ureterovaginal
fistula is a reasonable recommendation. However, equally important is the development of a ureteral stricture causing ‘silent
hydronephrosis’. After stent removal the patient may develop a distal ureteral stricture with a completely asymptomatic hydronephrosis
— ‘silent hydronephrosis’. Although the patient may be clinically asymptomatic, the renal units remain in jeopardy. Therefore,
routine periodic follow-up with radiologic studies is warranted after stent removal. 相似文献

Pheochromocytoma and paraganglioma: comparison of MR imaging with CT and I-131 MIBG scintigraphy 总被引:6,自引:0,他引:6
To ascertain the magnetic resonance (MR) imaging characteristics of pheochromocytomas and paragangliomas and to compare MR with computed tomography (CT) and iodine-131 metaiodobenzylguanidine (I-131 MIBG), 19 patients (18 with pheochromocytomas, one with a paraganglioma) were studied. The 18 patients with pheochromocytomas had had positive findings with I-131 MIBG scintigraphy. Abdominal pheochromocytomas were generally hypointense compared with normal liver on T1-weighted MR images and extremely hyperintense on T2-weighted MR images. MR imaging was preferable to CT in the evaluation of primary pheochromocytomas due to superior tissue characterization, particularly in the patient with hypertension and borderline catecholamine levels. For patients with recurrent or metastatic disease, the data suggest that I-131 MIBG scintigraphy is the examination of choice. 相似文献
