A technique of hepatic resection is described and the results of 150 resections are reviewed. Hepatic transection was performed, under intermittent portal inflow occlusion, using ultrasonic aspiration to skeletonize portal branches and venous tributaries. Control of venous haemorrhage during resection was optimized by argon beam coagulation and lowering central venous pressure to between 0 and 4 cmH2O by extradural blockade and systemic nitroglycerine infusion. One patient with jaundice died in hospital, giving a mortality rate of 0.7 per cent. There were no deaths in patients without jaundice and cirrhosis. Fifteen patients (10.0 per cent) had significant complications, nine medical and six surgical, including three bile leaks (2.0 per cent). Mean blood loss was 814 ml for the whole study but only 434 ml in the last 4 years. During this latter period mean blood transfusion in hospital was 0.5 units and mean postoperative haemoglobin value fell by 0.7 g per 100 ml. Hepatic resection can be performed with the same degree of confidence and similar low morbidity as any other major surgical procedure.
SFPV harvest results in minimal mid-term to late-term lower-extremity venous morbidity despite outflow obstruction. The most likely mechanisms preserving clinical status include the low incidence of mild reflux, the presence of collateral venous channels, and the lack of progression in abnormal harvest limb physiology. The absence of the ipsilateral GSV does not adversely affect clinical outcome.
Preliminary experience with CIB infusion/PCA in the aftermath of major liver resection has demonstrated its simplicity and safety as an alternative method of postoperative pain control. Further study is required to investigate the role of CIB infusion/PCA as a practical alternative to epidural analgesia or PCA alone.
The combination of CIB + PCA provides pain control similar to that provided by CEA, but facilitates lower opioid consumption after major hepatectomy. It has the potential to replace epidural analgesia, thereby avoiding the occurrence of rare but serious complications.
After liver resection, renal failure is rare but patients with an elevated creatinine pre-operatively are at an increased risk of both renal and non-renal complications.
Patch angioplasty during carotid endarterectomy (CEA) has been shown to reduce the incidence of both early and late complications. Controversy continues, however, over the ideal patch material. Bovine pericardium (Vascu-Guard Biovascular Inc., Saint Paul, MN) offers an attractive alternative to other patch materials because of its handling and suturing characteristics that are similar to that of autogenous material. This study examines the perioperative and midterm results of bovine pericardial patch angioplasty during CEA. We studied 112 patients who underwent 129 CEAs with bovine pericardial patch angioplasty during an 18-month period. Data were collected regarding demographics, operative indications, perioperative complications, and the occurrence of late adverse outcomes based primarily on follow-up arterial duplex studies. Among this group there were 63 male (56%) and 49 female (44%) patients whose mean age was 71.8 ± 9.1 years. In these patients there was the typical distribution of atherosclerotic risk factors. Seventy-four patients (66%) had symptomatic disease preoperatively and the remaining 38 patients (34%) were asymptomatic. Temporary cranial nerve palsy occurred in three patients (2%). There were no perioperative strokes, acute occlusions, bleeding episodes requiring reoperation, or deaths. The patients were followed up to 54 months postoperatively with a mean follow-up time of 41.7 ± 4.4 months. During this period two patients (2%) developed three significant restenoses (70–99%). All required reoperation. There were no asymptomatic occlusions, infections, aneurysms, or rupture. These data demonstrate that bovine pericardial patch angioplasty during CEA is associated with a low incidence of both perioperative and midterm adverse outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
