Saaya S, et al. A prospective randomized trial on endovascular recanalization with stenting vs. remote endarterectomy for the superficial femoral artery total occlusive lesions. J Vasc Surg. 2022 Feb 26:S0741-5214(22)00380-9. Full-text for Emory users.
Key Findings: In patients with superficial femoral artery total occlusive lesions of size greater than 250 mm, the 1-year and 4-year cumulative primary patencies of stenting (EI) and remote endarterectomy (RE) were 83% vs 82% and 28% vs 46% (P = .04), respectively. Patencies of endovascular reintervention subgroups (65 patients in the EI subgroup and 32 patients in the RE subgroup) were 37% and 60% (P = .04), respectively.
Take Home Message: RE has a better 4-year primary patency compared with stenting in patients with superficial femoral artery total occlusive lesions of size greater than 250 mm. Endovascular reinterventions after RE showed a higher patency compared with reinterventions after EI.

“Although recommendations from existing guidelines are conflicting [9,10] and recent well-designed RCTs are lacking, as many as 97% of surgeons irrigate wounds in an effort to reduce the risk of SSI [6,7]. The most commonly used irrigation solution is saline followed by aqueous PVP-I or antibiotic solutions [6,42,43]. The efficacy and clinical safety of irrigation with these solutions has been the subject of debate [11, 44]. Various concentrations of PVP-I are effective rapidly against a broad spectrum of pathogens, methicillin-resistant S. aureus (MRSA) included [45,46]. However, some in vitro studies [47-49] have reported a negative effect of PVP-I on tissue regeneration, and older case studies describe serum iodine toxicity as a result of irrigation [50-52]. However, these adverse effects could not be substantiated in clinical trials [29-35;41].” (p. 515)

Results: The most frequent Child-Turcotte-Pugh (CTP) score was A, The most frequent cause of cirrhosis was hepatitis C virus (HCV), while biliary colic was the most frequent presentation. The harmonic device was used in 39.9% of patients, with a significant correlation between it and lower operative bleeding, lower blood and plasma transfusion rates, higher operative adhesions rates, lower conversion to open surgery and 30-day complication rates, shorter operative time and post-operative hospital stays where operative adhesions and times were independently correlated. The 30-day morbidity and mortality were 22.1% and 2.3% respectively while overall survival was 91.5%, higher CTP, and model for end-stage liver disease (MELD) scores, higher mean international normalization ratio (INR) value, lower mean platelet count, higher operative bleeding, higher blood, and plasma transfusion rates, longer mean operative time and postoperative hospital stays were significantly correlated with all conversion to open surgery, 30-day morbidities and mortalities.
Conclusion: LC can be safely performed in cirrhotic patients. However, higher CTP and MELD scores, operative bleeding, more blood and plasma transfusion units, longer operative time, lower platelet count, and higher INR values are predictors of poor outcome that can be improved by proper patient selection and meticulous peri-operative care and by using Harmonic scalpel shears.

“Liver disease may result from viral hepatitis and iron overload due to multiple transfusions of blood products or due to disease activity causing varying changes in vasculature. The clinical spectrum of disease ranges from ischemic injury due to sickling of red blood cells in hepatic sinusoids, pigment gall stones, and acute/chronic sequestration syndromes. The sequestration syndromes are usually episodic and self-limiting requiring conservative management such as antibiotics and intravenous fluids or packed red cell transfusions. However, rarely these episodes may present with coagulopathy and encephalopathy like acute liver failure, which are life-threatening, requiring exchange transfusions or even liver transplantation.” (Praharaj DL, et al., p. 82)

“Evidence from a small study in 1971 suggests that use of 100% oxygen in patients with spontaneous pneumothorax can increase the rate of absorption fourfold compared to air (on the basis of mean reduction in pneumothorax size of 4.8 and 18 cm 2 /day, respectively). The rationale is that by reducing the partial pressure of nitrogen in the inspired gas, and thus in pleural capillaries, the rate of nitrogen absorption from the pneumothorax is increased, thereby increasing the rate of resolution of the pneumothorax.” (p. 1545)
