Primary polyarteritis nodosa presenting as acute symmetric quadriplegia.

We report a case of peripheral neuropathy presenting as acute symmetric areflexic quadriplegia in the setting of a well-defined clinical, histopathologic, and angiographic diagnosis of classic polyarteritis nodosa. While it is usually easy to recognize the typical clinical presentation of necrotizing angiopathy-induced peripheral neuropathy as a mononeuritis multiplex or a distal polyneuropathy in association with a collagen vascular disease, clinicians must be equally sensitive to a number of more challenging possibilities. Acute quadriplegia similar to that seen in Guillain-Barré syndrome can be secondary to primary classic polyarteritis nodosa and the former may be the chief or even the sole manifestation of the latter.

[Myocardial infarction in a young woman with left atrial myxoma].

A 38 year old female patient without coronary risk factors suffered an acute myocardial infarction. Echocardiographic and cardiac catheterization was undertaken and a left atrial mass with normal coronary arteries was assessed. The tumor mass was successfully resected and pathological examination of the specimen disclosed a myxoma. Three months after the operation the patient is symptom-free and an echocardiogram taken at this time showed no evidence of tumor. A bibliographic review of the association cardiac myxoma and coronary artery occlusion or myocardial infarction is done.

Complications of circulatory assistance with intra-aortic balloon pumping: a comparison of surgical and percutaneous techniques.

One hundred and two consecutive patients who underwent circulatory support with intra-aortic balloon pumping were reviewed. All patients underwent surgery for coronary bypass, resection of ventricular aneurysm, or valve replacement. Circulatory assistance was initiated preoperatively in 21 patients and postoperatively in 81 patients. Insertion of the balloon catheter was attempted randomly by the surgical technique or by the percutaneous method in 47 patients each. The surgical insertion failed in five patients (10.6%), and the percutaneous method was a failure in four patients (8.5%). All failures with both techniques occurred when catheter insertion was attempted postoperatively. Among 85 patients studied for complications, there were 17 vascular and 3 wound complications (23.5%). The complication rate with the surgical technique was 11.4% and that of the percutaneous insertion 30.6%, a difference that is significant. The mean duration of circulatory support was significantly longer in patients who developed vascular complications (123 hours vs 78 hours). Vascular complications resulted in the loss of limb in two patients, one in each group. There were two deaths directly related to the use of circulatory assistance, one from perforation of the iliac artery and one from acute renal failure following revascularization of a severely ischemic limb, both in the percutaneous group. Thus, percutaneous balloon insertion has a failure rate similar to surgical insertion but a higher rate of complications, partly caused by percutaneous removal of the catheter. Practical recommendations are made in regard to the use and management of the technique.
