BACKGROUND

This case report describes a rare presentation of double-vessel Spontaneous Coronary Artery Dissection (SCAD) in a 54-year-old male. One dissection occurred in a coronary artery with atherosclerotic plaque deposition, while the second vessel exhibited dissection without evidence of plaque deposition, trauma or iatrogenic manipulation such as percutaneous coronary intervention. The patient, a known hypertensive and dyslipidemic, had a prior diagnosis of heart failure with reduced ejection fraction (HFrEF). He presented with progressively worsening shortness of breath and orthopnea (two-pillow orthopnea for three years. An initial coronary angiogram was recommended due to a high suspicion of underlying coronary artery disease (CAD).Subsequent diagnostic workup revealed multisegmental wall motion abnormalities on 2D echocardiography with Doppler imaging. Laboratory tests, including electrolytes, were unremarkable. A follow-up coronary angiogram revealed mild to moderate CAD in the left anterior descending (LAD) artery and spontaneous coronary artery dissection involving both the LAD and the right coronary artery (RCA). The patient was managed conservatively with aspirin and discharged on a regimen of sacubitril/valsartan, ivabradine, trimetazidine, and rosuvastatin. As typically seen in SCAD cases, conservative medical management was preferred over invasive procedures such as PCI or coronary artery bypass grafting (CABG), which are reserved for select clinical situations.

Intraoperative hemorrhage is a life-threatening complication during neurosurgery, especially in posterior fossa surgery, where critical vasculature and brain structures are present. Adenosine has been used in neurovascular surgery, particularly in the management of intraoperative aneurysm rupture and hemorrhage for its ability to produce transient flow arrest. This case report describes a novel application for adenosine, in which adenosine-induced flow arrest was used to facilitate control of a vascular injury sustained during meningioma surgery.

A 46-year-old female diagnosed with a petroclival meningioma after presenting with a several-month history of headache, dizziness, and loss of balance underwent craniotomy and excision of the meningioma. The patient received general endotracheal anesthesia, and was maintained on remifentanil, propofol, and low-dose sevoflurane. During posterior excision of the meningioma, the basilar artery was inadvertently lacerated, resulting in significant blood loss. Adenosine was given through a subclavian catheter, and produced severe bradycardia, hypotension, then asystole for approximately 50 seconds. Adenosine-induced flow arrest allowed for initial control of the vascular injury through coagulation, while further hemostasis was achieved through hemostatic agents and muscle tamponade.

This case report demonstrates the usefulness of adenosine-induced flow arrest in the management of intraoperative hemorrhage from an intracranial vascular injury. Adenosine-induced flow arrest has documented safety and efficacy in other neurosurgical applications. As the management of intraoperative hemorrhage is an essential component of neuroanesthesia, this technique may be considered in similar circumstances of major vascular injury to facilitate hemostasis.

Introduction: Pituitary apoplexy is a rare, life-threatening condition resulting from hemorrhage or infarction of the pituitary gland, most commonly in patients with pre-existing pituitary tumors. It typically presents with a sudden headache, visual disturbance, ophthalmoplegia, and altered mental status. An uncommon but serious complication is ischemic stroke in the middle cerebral artery (MCA) territory, particularly in the absence of direct internal carotid artery (ICA) compression. Case: We report a case of a 36-year-old male who presented with headache, visual impairment, and fever. Initial computed tomography (CT) brain imaging demonstrated a heterogeneous sellar lesion with peripheral calcification measuring 2.4 × 3.2 × 2.7 cm, suggestive of a pituitary mass with possible apoplexy, without evidence of acute cerebral infarction. The patient subsequently developed dysarthria, hemianopia, and reduced consciousness, prompting repeat neuroimaging. Follow-up CT revealed a large hypodense area in the right fronto-parieto-temporal region consistent with ischemic infarction. Magnetic resonance imaging confirmed an acute infarct in the right MCA territory without hemorrhagic transformation. A sellar-suprasellar mass measuring 2.3 × 2.8 × 3.8 cm was identified, consistent with a pituitary macroadenoma with intratumoral hemorrhage compressing the optic chiasm, but without direct right ICA compression. Time-of-flight mineralocorticoid receptor antagonists demonstrated attenuated flow in the right ICA (C2–C7), suggesting intracranial ICA thrombosis and reduced perfusion in the right MCA and its branches. Laboratory evaluation revealed hyperthyroidism and hypocortisolism, with no evidence of coagulopathy. The patient was treated with corticosteroid replacement and carbimazole and referred for neurosurgical management. Conclusion This case highlights a rare association between pituitary apoplexy and MCA stroke, possibly mediated by vasospasm, inflammation, or hypercoagulability. More research is needed to understand this connection and improve treatment strategies.

OBJECTIVE: To assess the association of single nucleotide polymorphisms (SNP) of the cell division cycle 42 (CDC42) gene with Pulmonary artery systolic pressure (PASP) among patients with Congenital heart disease (CHD). METHODS: In this observational study, clinical data and blood samples were collected from 579 CHD patients with left-to-right shunt who presented to our hospital between January 2012 and January 2017. SNPs of the CDC42 gene were genotyped using an improved multiple ligase detection reaction. Multiple linear regression was applied to evaluate the association of CDC42 gene variants with PASP. This study was approved by the Medical Ethics Committee of the First Affiliated Hospital of Xinjiang Medical University (Ethics No.: 20180222-102). RESULTS: Polymorphisms at rs2501256 and rs34896897 of the CDC42 gene were significantly associated with PASP. Compared with the CC genotype at rs2501256, TT and CT carriers displayed higher PASP [TT vs. CC: B (95%CI) = 4.01 (1.95, 6.07), P < 0.001; CT vs. CC: B (95%CI) = 2.91 (0.63, 5.19), P < 0.001]. Similarly, GG and GA genotypes at rs34896897 were associated with higher PASP compared to the AA genotype [GG vs. AA: B (95%CI) = 26.15 (20.45, 31.84), P < 0.001; GA vs. AA: B (95%CI) = 7.19 (4.31, 10.08), P < 0.001]. Genetic model analyses demonstrated significant differences for both rs2501256 and rs34896897 under dominant, additive, and recessive models (P < 0.05). TT carriers at rs2501256 exhibited larger left-and right-atrial diameters, whereas GG carriers at rs34896897 showed greater right-atrial and right-ventricular end-diastolic dimensions. Subgroup analyses revealed no association between rs2501256 and PASP in males, individuals younger than 18 years, Uyghur ethnicity, or those with ventricular septal defects. CONCLUSION CHD patients carrying the minor alleles of rs2501256 and rs34896897 in the CDC42 gene present higher incidence of PASP compared to those carrying the common alleles.

OBJECTIVE

To describe a case of a craniomaxillofacial penetrating injury focusing on the importance of a multidisciplinary approach with insights into the surgical planning for successful removal of the foreign body during the pandemic.

METHODS

Design: Case Report

Setting: Tertiary Government Training Hospital

Patient: One

RESULTS

A 15-year-old boy presented with a work-related puncture wound in the right nasomaxillary area with accompanying soft-tissue swelling. Physical examination of his face showed no external foreign body. Craniofacial computed tomography scans revealed a rod-shaped opaque foreign body about 12 cm in length and 9 mm in diameter lodged in the right maxillary sinus extending to the right temporal lobe. The otolaryngology-head and neck surgeon and neurosurgeon planned the crucial extraction of the foreign body, but the requirement for a negative RT-PCR, blood products, and additional imaging delayed this emergent operation. The foreign body was eventually removed via combined trans-antral approach and right frontotemporal craniotomy, zygotomy, and craniectomy around the foreign body in the temporal floor with duraplasty and cranioplasty.

CONCLUSION

Successful treatment of penetrating craniomaxillofacial injuries involves diligent clinical assessment, radiologic diagnosis and a well-planned multidisciplinary surgical approach. Delays in treatment may be beneficial if they allow precise location of the foreign body and thorough evaluation of involved structures. Safeguarding the healthcare workers during the pandemic was as important as ensuring a successful and safe surgery for the patient.

The most common cause of mortality after a kidney transplant is a cardiovascular event. This is why most patients with poor cardiovascular status are denied a transplant. A 70-year-old male, ESRD from hypertensive nephropathy, was declined renal transplantation in the United States for advanced age, severe coronary disease and abdominal aortic aneurysm. The patient sought a second chance at a possible transplantation here in the Philippines. After a comprehensive cardiovascular evaluation, he underwent coronary artery bypass graft for a three-vessel disease followed by endovascular aneurysm repair (EVAR) which he tolerated well. After four weeks, he underwent a living-related kidney transplantation with immediate allograft function. On postoperative day 5, after catheter removal, the patient was unable to void spontaneously. He was diagnosed with benign prostatic obstruction and underwent transurethral resection of the prostate. He tolerated this and voided freely since catheter removal. One year later, the patient has a functioning allograft and stable cardiac status. High risk patients with cardiovascular disease may be given a chance at kidney transplantation after a meticulous evaluation and optimization.

Wunderlich Syndrome is a rare potentially life-threatening phenomenon that involves spontaneous non-traumatic retroperitoneal hemorrhage. At present, identifying the course of conservative management in these patients, especially in pregnancy, has not been clinically established. Presented here is a known case of Tuberous Sclerosis Complex with a Bilateral, 10cm Angiomyolipoma in a 31-year-old female, initially managed with active surveillance. At 27 weeks of pregnancy, she presented with a sudden onset of left flank pain with a hematocrit of 22%. Anemia was corrected with blood transfusions. A contrast-enhanced MRI of the abdomen showed a large subcapsular perirenal hematoma of the left kidney. Renal angioembolization of the bleeding segmental renal artery was done. The patient was conservatized until 37 weeks of pregnancy and underwent cesarean section delivery.

Four months after angioembolization, she had a recurrence of the left flank pain associated with gross hematuria and hypovolemic shock. The patient underwent emergency renal exploration of the left kidney via a transabdominal approach. Three liters of hemoperitoneum and a large expanding left retroperitoneal hematoma were noted intraoperatively. Early vascular control before nephrectomy of the left kidney was done. The postoperative course was unremarkable and the patient was discharged with improved condition.

This case displays a unique course in the management of a bleeding angiomyolipoma especially during pregnancy. Renal angioembolization can aid in achieving the age of viability in pregnancy. However, close monitoring for rebleeding should be kept in mind. A lower threshold for conservative management should be utilized when patients have a previous history of bleeding.

Cardiac myxomas are primary cardiac tumors that presents with symptoms of hemodynamic derangement from obstruction of flow within the cardiac chambers or deformation of a cardiac valve and symptoms associated with embolization.

In this case report, we are presented with a 45-year-old female, diabetic with paroxysmal atrial fibrillation, fair functional capacity, ambulatory, with chief complaint of dyspnea. Admitted as a case of Left atrial myxoma with Pulmonary embolism (proximal right lower lobe, distal left main pulmonary artery division, and superior segmental division of the left lower lobe).

Left atrial myxoma was the first diagnostic consideration, followed by other primary cardiac tumors, and thrombus. Patient was then prepared for surgery and underwent excision of LA myxoma with CardioCel Bioscaffold patch on the inter-atrial septum, mitral ring annuloplasty with plication of the A2-A3 segment, thrombectomy of right inferior pulmonary vein, utilizing cardiopulmonary bypass. Upon pathological examination, the mass was found to be sarcoma with noted myxoid features. The objective of this report is to describe a case of this rare disease entity, and to discuss its presentation, pathological findings and management.

The surgical treatment of the rare extracranial carotid artery aneurysm can lead to significant thromboembolic events in 4.4% of cases. Intraoperative monitoring has helped detect hypoperfusion and probable ischemic events, but this is not widely available in resource-limited hospitals in the Philippines. This case highlights the use of a portable standard 21-channel EEG machine for intraoperative monitoring in a tertiary government hospital. In addition, it highlights a conception of a protocol for the intraoperative electroencephalogram monitoring of carotid endoaneurysmorrhaphy procedures in a resource-limited setting. During the aneurysmorrhaphy procedure, the authors collaborated with the surgeons and the anesthesiologists to provide feedback about EEG changes during the operation. After a pre-induction baseline was recorded, continuous EEG monitoring was performed until the patient emerged from anesthesia. Mild EEG changes, attributed to relative hypotension, were observed during the procedure. These episodes were responsive to BP augmentation. There were no EEG changes observed during carotid cross-clamping. Shunting was not recommended to the surgical team. No new neurologic deficits were documented postoperatively and on follow-up after six months. This paper illustrates how an intraoperative team was formed, and intraoperative EEG was utilized for a complex carotid endoaneurysmorrhaphy for a patient with ECAA in a tertiary government hospital in the Philippines.
