In diagnosing a brain tumor, it is essential to obtain samples from many areas of the tumor. Although there are reports about the suitability of material obtained by cavitron ultrasonic surgical aspirator(CUSA), there is a paucity of reports regarding conventional intraoperative suction. This study was performed to evaluate the usefulness of the suction fluid and the effect of different hemolytic fixatives. Intraoperative suction fluid was obtained from 2 pituitary adenomas and 2 choroid plexus carcinomas. In two cases of mixed astro-oligodendroglioma, one of glioblastoma multiforme and 3 of meningioma, the fluid was collected by CUSA. Each sample was divided into four bottles for the different fixatives such as 0.1N HCI, 10% acetic acid, 95% alcohol, and no additive. All cases were evaluated by the both cytologic smear and cell block preparations, and were reviewed with concomitant histologic diagnosis. The result showed a good correlation between the cytologic study and the histologic diagnosis and 95% alcohol was found to be superior to other fixatives in ceil preservation.

Complications experienced during lymphatic surgery have not been ubiquitously reported, and little has been described regarding how to prevent them. We present a review of complications reported during the surgical management of lymphedema and our experience with technical considerations to reduce morbidity from lymphatic surgery. A comprehensive search across different databases was conducted through November 2020. Based on the complications identified, we discussed the best approach for reducing the incidence of complications during lymphatic surgery based on our experience. The most common complications reported following lymphovenous anastomosis were re-exploration of the anastomosis, venous reflux, and surgical site infection. The most common complications using groin vascularized lymph node transfer (VLNT), submental VLNT, lateral thoracic VLNT, and supraclavicular VLNT included delayed wound healing, seroma and hematoma formation, lymphatic fluid leakage, iatrogenic lymphedema, soft-tissue infection, venous congestion, marginal nerve pseudoparalysis, and partial flap loss. Regarding intra-abdominal lymph node flaps, incisional hernia, hematoma, lymphatic fluid leakage, and postoperative ileus were commonly reported. Following suction-assisted lipectomy, significant blood loss and transient paresthesia were frequently reported. The reported complications of excisional procedures included soft-tissue infections, seroma and hematoma formation, skin-graft loss, significant blood loss, and minor skin flap necrosis. Evidently, lymphedema continues to represent a challenging condition; however, thorough patient selection, compliance with physiotherapy, and an experienced surgeon with adequate understanding of the lymphatic system can help maximize the safety of lymphatic surgery.
