ABSTRACT

Objective:To investigate the clipping methods of ruptured posterior communicating artery (PCoA) aneurysms of medial posterior inferior type (aneurysms located at the medial posterior inferior part of internal carotid artery or occluded by the internal carotid artery) during conventional pterional craniotomy.Methods:Seven patients with ruptured PCoA aneurysms, admitted to our hospital from January 2004 to January 2020, were chosen in our study. The clinical data and surgical efficacies of these patients were retrospectively analyzed.Results:The anterior choroidal artery (AChA) was accidentally clipped in 2 patients during the surgery, of which one was released after adjustment and one was avoided after multiple adjustments. Due to severe acute brain swelling, the brain tissues of the anterior temporal lobe were removed for about 20 mm in 2 patients, and the anterior temporal lobe was retracted posteriorly by platens in 5 patients. All aneurysms disappeared in the postoperative CTA images, no residual neck was found, and the parent artery remained unobstructed. One patient had cerebral infarction in the AChA supplying area. All patients were followed up for 1-6 years, with an average of 27.6 months. Six patients recovered completely without neurological dysfunction. One patient had contralateral hemiplegia, with muscle strength grading III, walking on crutches, and basic living by himself.Conclusion:It's difficult to clip the ruptured PCoA aneurysms of medial posterior inferior type by conventional pterional craniotomy; so straight and curved aneurysm clips can be used to clip aneurysms by expanding the inter-cisternal space around the aneurysms.

ABSTRACT

Objective To discuss the risk factors and therapeutic options of delayed would healing after craniotomy. Methods Sixteen patients with poor would healing after craniotomy, admitted to our hospital from January 2012 to September 2016, were chosen in our study. The secretion culture results, imaging findings, devastating infections, paranasal sinuses, would debridement and prognoses were analyzed. Results All 16 patients were treated with artificial materials in the initial operations. The paranasal sinuses were confirmed open during operation in 7 patients by comparison of preoperative imaging. Six patients who had positive results by secretion culture were cured through removal of the artificial materials and bone flap during the first debridement surgery; 4 of the 10 patients who had negative results were cured only by removing artificial materials during the first debridement surgery, and the remaining 6 were cured with reoperation through removal of the bone flap. Conclusions Chronic infection caused by bacteria, which mainly comes from surgical field and paranasal sinuses, is important to elucidate the mechanism of delayed would healing after craniotomy. The implants and autologous tissues have important roles in this process. Early complete debridement is very critical on such infected would, meanwhile we must repack the ostia of the sinuses based on preoperative images, and relax the indications for throwing the bone flap.

ABSTRACT

Objective To investigate the different memory outcomes in temporal lobe epilepsy patients underwent different surgical approaches.Methods Two hundred forty-eight patients with temporal lobe epilepsy and hippocampal scle-rosis underwent standard anterior temporal lobectomy ( ATL, n=83 ) or selective amygdalohippocampectomy ( SAH, n=165) from 2009 to 2013.All the patients underwent clinical memory function assessment before surgery, 3 months and 2 years after surgery respectively.Results The memory quotient ( MQ) of patients who underwent brain surgery in the domi-nant hemisphere significantly decreased 3 months after surgery (74.5 ±16.2, 75.6 ±19.5) compared to presurgery MQ (82.9 ±15.8, 83.2 ±21.2) in both ATL and SAH groups (P<0.05).Although MQ was slightly recovered at 2 years af-ter surgery, MQ (75.1 ±14.1, 76.1 ±17.6) was still significantly lower compared with presurgery MQ (P<0.05).A-mong this, both the decrease extent of the MQ 3 months after surgery and 2 years after surgery were smaller in the SAH group than in the ATL group (7.6 vs.8.4;7.1 vs.7.8).The MQ of patients who underwent brain surgery in the non-dominant hemisphere (either ATL or SAH ) increased slightly 3 months after surgery (87.2 ±15.1, 88.1 ±16.9) com-pared to presurgery MQ (85.5 ±13.5, 85.3 ±19.7) although the difference was not statistically significant.The MQ of these two groups improved significantly 2 years after surgery (92.8 ±12.7, 93.7 ±17.1)(P<0.05).The improvement extent of the MQ was larger in the SAH group than in the ATL group (8.4 vs.7.3).Conclusions SAH may be better than ATL in the maintenance of memory function in patients with temporal lobe epilepsy and hippocampal sclerosis.
