ABSTRACT
This study describes the risk of thrombotic and hemorrhagic complications, both intraoperatively, and up to 1 month following visceral transplantation. Data from 48 adult visceral transplants performed between 2010 and 2017 were retrospectively studied [32 multivisceral (MVTx); 10 isolated intestine; six modified-MVTx]. Intraoperatively, intracardiac thrombosis (ICT)/pulmonary embolism (PE) occurred in 25%, 0% and 0% of MVTx, isolated intestine and modified MVTx, respectively, and was associated with 50% (4/8) mortality. Preoperative portal vein thrombosis (PVT) was a significant risk factor for ICT/PE (P = 0.0073). Thromboelastography resembling disseminated intravascular coagulation (DIC) (r time <4 mm combined with fibrinolysis or flat-line) was statistically associated with occurrence of ICT/PE (P < 0.0001). Compared to subgroup without ICT/PE, occurrence of ICT/PE was associated with an increased demand for all blood product components both overall, and each surgical stage. Hyperfibrinolysis (56%) was identified as cause of bleeding in MVTx. Incidence of postoperative thrombotic event at 1 month was 25%, 30% and 17% for MVTx, isolated intestine and modified MVTx, respectively. Incidence of postoperative bleeding complications at 1 month was 11%, 20% and 17% for MVTx, isolated intestine and modified MVTx. In conclusion, MVTx recipients with preoperative PVT are at an increased risk of developing intraoperative life-threatening ICT/PE events associated with DIC-like coagulopathy.

Advanced renal cell carcinoma (RCC) resection has important anesthetic management implications, particularly when tumor extends, suprahepatic, into the right atrium. Use of transesophageal echocardiogram (TEE) is essential in identifying tumor extension and guiding resection. Latest surgical approach avoids venovenous and cardiopulmonary bypass yet requires special precautions and interventions on the anesthesiologist's part. We present a case of Level IV RCC resected without cardiopulmonary bypass and salvaged by TEE guidance and detection of residual intracardiac tumor.
