Distal splenorenal vs. portal-systemic shunts after hemorrhage from varices: a randomized controlled trial.

Between 1975 and 1983, 303 cirrhotic patients with endoscopically proven major variceal hemorrhage were admitted to the participating hospitals of the Boston-New Haven Collaborative Liver Group. Of these, 274 were evaluated for admission to a prospective, randomized controlled trial comparing portal-systemic shunts with distal splenorenal shunts. The criteria for inclusion were as follows: (i) a portohepatic pressure gradient greater than or equal to 12 mmHg; (ii) angiographic evidence of antegrade portal venous flow; (iii) angiographic demonstration that the inferior vena cava and portal, splenic and left renal veins were anatomically suitable for either a portal-systemic or distal splenorenal shunt, and (iv) the patient was a reasonable operative risk.

An improved system for surgical excision of needle-localized nonpalpable breast lesions.

A technique for improved localization and surgical excision of nonpalpable breast lesions is described. The method employs an atraumatic outer stiffening cannula which is available in a variety of lengths and eliminates several of the technical difficulties encountered during these procedures. Successful initial excision of over 50 consecutive nonpalpable breast lesions has been obtained with this technique.

The role of cranial computed tomography in carotid surgery.

In patients who present with TIA, RIND, or CVA, the cranial CT scan can rule out other etiologies for neurologic symptoms. In addition to the clinical presentation, the CT scan allows further stratification of patients being considered for carotid endarterectomy. We propose that patients be classified as TIA (+), TIA (-), RIND (+), or CVA (-).

In situ saphenous vein bypass grafts for limb salvage. A current fad or a viable alternative to reversed vein bypass grafts?

Revascularization of the lower extremity using the in situ saphenous vein bypass graft has resurfaced as a clinical alternative to reversal of the saphenous vein. Early patency rates have been excellent, however, concern has been raised about the durability of the in situ technique. Our total experience with this technique has been reviewed to evaluate its effectiveness on a teaching vascular service.

Stroke after carotid endarterectomy: risk as predicted by preoperative computerized tomography.

In patients undergoing carotid endarterectomy, the role of preoperative computerized tomographic head scanning in predicting the risk of postoperative neurologic deficit was determined by a retrospective evaluation of a select group of 107 consecutive patients with preoperative scans. Patients with infarction determined preoperatively by computerized tomography were found to be at a significantly higher risk for postoperative neurologic deficit than patients with a normal preoperative computerized tomographic scan. History and physical examination alone detected only 66 percent of the infarctions found with preoperative computerized tomographic scanning in these patients.

Distal splenorenal shunt vs. portal-systemic shunt: current status of a controlled trial.

A prospective controlled comparison of portal-systemic (PSS) and distal splenorenal shunts (DSRS) in cirrhotic patients who had survived hemorrhage from esophagogastric varices was undertaken 5 yr ago at five hospitals by the Boston-New Haven Collaborative Liver Group. The clinical and endoscopic criteria for massive hemorrhage were satisfied in 155 patients. Thirty-four patients were excluded, primarily because of uncontrolled hemorrhage.

Pseudocyst of the pancreas complicating distal splenorenal shunt. A report of three cases with successful percutaneous drainage.

Three cases of pseudocysts of the pancreas complicating the operative procedure of distal splenorenal shunt are reported. In all of these patients, gross changes in the pancreas, consistent with chronic pancreatitis were found. Attention is called to the possibility of this complication occurring in association with this particular operation, specifically, when it is carried out in patients who may prove to have a considerable degree of pancreatic and retroperitoneal fibrosis secondary to alcoholic pancreatitis.

Carotid endarterectomy in the presence of contralateral carotid occlusion: the role of EEG and intraluminal shunting.

Patients undergoing carotid endarterectomy in the presence of occlusion of the contralateral carotid artery appear at greater risk for operative-related stroke or death. We had experience with 37 such patients in a five-year period. Routine intraluminal shunting without EEG monitoring was used in nine patients.

Is axillo-bilateral femoral graft an effective substitute for aortic-bilateral iliac/femoral graft?: an analysis of ten years experience.

During the past ten years, 88 aorto-bilateral iliac/femoral grafts and 56 axillo-bilateral femoral grafts were electively performed for occlusive disease of the abdominal aorta or iliac vessels. The results of this retrospective study indicate that the axillo-bilateral femoral graft, although performed in an older population and more frequently for limb salvage, has a lower operative mortality than does conventional aortic bypass surgery with similar patency (76%) and survival (67%) at five years. However, axillo femoral grafting requires more frequent remedial surgery to obtain long term patency.

A comparison of the late patency rates of axillobilateral femoral and axillounilateral femoral grafts.

A total of 130 axillofemoral grafts were peformed in 120 patients from 1966 to present; 66 were axillobilateral femoral moral and 64 were axillounilateral femoral grafts. The average patient age was 66 years. The indications for operation were occlusive disease with rest pain or gangrene in 102 patients, severe claudication four, and bypass of a thoracic aneurysm in one.

Blood pressure, edema and proteinuria in pregnancy. 3. Study design, population and data characteristics.

1. The mean blood pressure runs a curvilinear pattern during the course of pregnancy, with the lowest reading between 20 and 27 weeks of gestation, a continuous rise from 28 to 36 weeks, followed by a plateau. 2.
