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.

Introduction: Aortic root dilatation is not uncommon in acromegaly as a result of persistent growth hormone (GH) excess, causing degenerative changes in the aortic wall. Acute and extensive aortic dissection is rare and a potentially fatal complication. Case: We report a 51-year-old male with acromegaly due to a GH-secreting pituitary macroadenoma with parasellar extension, diagnosed in 2014. As primary surgical therapy was not recommended, he received medical therapy, initially with monthly lanreotide depot injections and subsequently switched to pasireotide LAR for 7 years. Following tumor size reduction with medical therapy, he underwent transsphenoidal surgery followed by stereotactic radiotherapy for residual tumor. Despite multimodal intervention, growth hormone and insulin-like growth factor 1 levels were persistently mildly elevated and required combination medical therapy along with multiple hormone replacement therapies with thyroxine, hydrocortisone, and testosterone for panhypopituitarism. Both hypertension and diabetes were well controlled on treatment. In December 2025, he presented with sudden, severe central chest pain and rapidly progressive left lower limb weakness. Imaging studies with computed tomography aortography and lower limb angiogram detected an Extensive Type A Aortic Dissection with entry point proximal to the origin of the coronary arteries, extending to the right common carotid, internal and external carotid arteries, and distally into the left common iliac, proximal internal and external iliac arteries, which were completely thrombosed. He underwent emergency aortic dissection repair with hemi-aortic arch replacement of the ascending aorta and repair of perforated right coronary sinus wall, with two vessel CABG and lower limb femoral-femoral bypass. Postoperatively, he required prolonged ventilation and intensive care unit care due to multiple complications: pericardial and pleural effusions, repeated left lower limb thrombosis requiring left popliteal embolectomy, and embolic stroke of the right internal carotid artery and posterior cerebral artery with subsequent hemorrhagic transformation. He continued to recover well with intensive physiotherapy and acupuncture and is now able to ambulate independently Conclusion Cardiovascular surveillance with regular echocardiogram and specific monitoring for aortic dilatation is important in uncontrolled acromegaly. Consideration for surgical intervention in selected cases may be necessary to prevent acute dissection.

OBJECTIVE: To explore the feasibility of reconstruction of phonatory function by using a tubular free flap from upper-lateral upper arm to repair the laryngotracheal circumferential defect after near-total laryngectomy for laryngeal cancer. METHODS: A retrospective study was conducted on 7 patients who underwent near-total laryngectomy between June 2021 and October 2023, aged from 48 to 70 years (median, 59 years), 6 males and 1 female. The disease duration ranged from 1 to 11 months, with a median of 6 months. Pathological diagnosis of preoperative biopsy was squamous cell carcinoma. Tumor classification: glottic type in 5 cases, supraglottic type in 1 case, transglottic type in 1 case; TNM staging: T ₄N ₀M ₀ in 6 cases, T ₄N ₂M ₀ in 1 case; American Joint Committee on Cancer (AJCC) staging in 2017 was stage Ⅳ. Preoperative MRI angiography of upper arm was performed to investigate the blood supply in the upper and lateral regions of the upper arm. After near-total laryngectomy and bilateral neck lymph node dissection, the area of the laryngotracheal defect was measured. A free flap measuring 7.0 cm×5.0 cm to 8.0 cm×7.0 cm was harvested from the upper-lateral upper arm, rolled into a tube shape, and connected between the stump of the cervical trachea in the neck root and that of the epiglottis at the tongue base. Four patients received adjuvant radiochemotherapy, 1 patient received radiochemotherapy and targeted therapy, 2 patients adopted no further adjuvant treatment. RESULTS: All 7 patients were followed-up 1-2 years (mean, 1 year and 3 months). Four patients had primary wound healing, 2 patients had minor pharyngeal fistulas that healed after dressing change, 1 patient experienced pharyngeal fistula because of flap necrosis and the wound still healed without secondary surgery. All patients took food orally within 1 month after operation, and the tracheal cannula was retained. Six patients with survived flap gradually adapted to their new pronunciation mode and obtained satisfactory phonatory function from 15 days to 2 months after operation. Four patients had slight aspiration after operation. Till the end of the follow-up, all patients survived and no local recurrence or distant metastasis had been observed. The motor function of the upper arm was not affected, only partial sensory loss occurred in the area near the incision. The scar of the incision could be covered by the short sleeve so as to obtain a better aesthetic effect. CONCLUSION Using a tubular free flap from upper-lateral upper arm to repair the laryngotracheal circumferential defect after near-total laryngectomy for laryngeal cancer can achieve satisfactory phonatory restoration while preserve the motor function and aesthetics of the donor site.

Traumatic aortic injury (TAI) is an acute, critical, and severe disease, and then combined with multiple organ damage, it is even more dangerous. TAI progresses very rapidly, with a pre-hospital mortality rate of 57%-80%, and even when arriving at the hospital, more than one-third of the patients die within 4 h, and it is the 2nd leading cause of death in individuals aged 4-34 years. In addition, the incidence of TAI combined with injury was 81.4%. Therefore, early diagnosis, expeditious surgery, and timely and effective multidisciplinary cooperation are essential for successful rescue. The authors report 2 patients with acute traumatic aortic dissection combined with multiple organ injuries and treated with emergency endovascular surgery to discuss their clinical characteristics and treatment experience, and to provide experience in the diagnosis and treatment of such patients.

Testicular tumor is the most common solid malignancy in males under 40 years of age. This malignancy is known to have a negative impact on male fertility. Therefore, several techniques for sperm retrieval have been proposed, including microdissection testicular sperm extraction (mTESE). The objective of this study was to review the literature on the outcomes of oncological (Onco)-mTESE at the time of radical orchiectomy. We conducted a comprehensive literature search through PubMed, Scopus, and Cochrane Central Controlled Register of Trials. Only studies reporting ex vivo mTESE in patients with testicular tumor were considered. Twelve papers met the inclusion criteria and were included in this review. Tumor size was identified as the sole preoperative factor influencing spermatogenesis. The considered studies demonstrated a satisfactory success rate for Onco-mTESE, associated with a similarly valid percentage of live healthy births through assisted reproductive technology. Currently, no comparison has been made between Onco-mTESE and conventional Onco-TESE, hence further assessment is required. In cases where the tumor completely replaces the cancer-bearing testicle, a contralateral micro-TESE may be a viable alternative. However, the surgeon should evaluate associated risks and benefits preoperatively. In conclusion, Onco-mTESE at the time of radical orchiectomy appears to be a promising therapeutic option for young patients with testicular tumors. Nevertheless, additional studies are necessary to achieve a definitive conclusion.

When microdissection testicular sperm extraction (micro-TESE) fails, a redo procedure may be the only option for patients who want a biological child. However, there are many gaps of knowledge surrounding the procedure, which need to be addressed to help clinicians and patients make informed decisions. This review explores redo micro-TESE in the context of nonobstructive azoospermia (NOA). Literature was searched using Google Scholar, Medline, and PubMed. Search terms were "NOA" AND "second microdissection testicular sperm extractions" AND "redo microdissection testicles sperm extraction" AND "repeat microdissection testicular sperm extractions" AND "failed microdissection testicular sperm extractions" AND "salvage microdissection testicular sperm extractions". Only original articles in English were included. A total of nine articles were included, consisting of four retrospective and five prospective studies. The time gap between the first and second micro-TESE varied from 6 months to 24 months. Most of the included studies reported successful surgical sperm retrieval (SSR) in the second micro-TESE in the range of 10%-21%, except in one study where it reached 42%. It has not been presented any definitive information about the use of hormonal treatment or the benefit of varicocelectomy prior to the second micro-TESE. Patients with hypospermatogenesis and Klinefelter syndrome (KS) had the highest chance of success in redo surgery. In conclusion, redo micro-TESE following a negative procedure can lead to sperm recovery in 10%-21%. Patients with hypospermatogenesis and KS have a higher chance of success. There is no enough evidence to conclude which is the best hormonal stimulation if any before a redo surgery.

Nonobstructive azoospermia (NOA) is the most challenging and complex clinical scenario for infertile men. Besides circumstances such as hypogonadotropic hypogonadism, surgical sperm retrieval is typically necessary, and microdissection testicular sperm extraction (micro-TESE) is the procedure of choice for men with NOA desiring to father children with their own gametes. Micro-TESE results in the highest numbers of sperm cells retrieved for use with in vitro fertilization/intracytoplasmic sperm injection (ICSI) in comparison to all other techniques for surgical sperm retrieval in men with NOA. Several factors may affect sperm retrieval rate and ICSI outcomes, including the patient's age, testicular volume, histopathological and genetic profile, and serum hormone levels. This article aims to review the medical literature describing predictors of successful micro-TESE and the outcomes of ICSI in men with NOA.

Nonobstructive azoospermia (NOA) is considered the most challenging clinical scenario for infertile men and current treatments leave many men unsuccessful at being able to achieve a pregnancy with their partner using their own sperm. Microdissection testicular sperm extraction (micro-TESE) is the choice for men with NOA desiring to father children with their own gametes. Micro-TESE results in the highest numbers of sperm cells retrieved for use with in vitro fertilization/intracytoplasmic sperm injection. With suboptimal micro-TESE success rates of sperm retrieval and then pregnancy and live birth using the retrieved sperm with in vitro fertilization/intracytoplasmic sperm injection, advances to improve outcomes are necessary. This article comprehensively reviews the technologies investigated to date to improve the outcomes for men undergoing micro-TESE.

To investigate the impact of preoperative serum follicle-stimulating hormone (FSH) levels on the probability of testicular sperm retrieval, we conducted a study of nonobstructive azoospermic (NOA) men with different testicular volumes (TVs) who underwent microdissection testicular sperm extraction (micro-TESE). A total of 177 NOA patients undergoing micro-TESE for the first time from April 2019 to November 2022 in Shenzhen Zhongshan Obstetrics and Gynecology Hospital (formerly Shenzhen Zhongshan Urology Hospital, Shenzhen, China) were retrospectively reviewed. The subjects were divided into four groups based on average TV quartiles. Serum hormone levels in each TV group were compared between positive and negative sperm retrieval subgroups. Overall sperm retrieval rate was 57.6%. FSH levels (median [interquartile range]) were higher in the positive sperm retrieval subgroup compared with the negative outcome subgroup when average TV was <5 ml (first quartile [Q1: TV <3 ml]: 43.32 [17.92] IU l -1 vs 32.95 [18.56] IU l -1 , P = 0.048; second quartile [Q2: 3 ml ≤ TV <5 ml]: 31.31 [15.37] IU l -1 vs 25.59 [18.40] IU l -1 , P = 0.042). Elevated serum FSH levels were associated with successful micro-TESE sperm retrieval in NOA men whose average TVs were <5 ml (adjusted odds ratio [OR]: 1.06 per unit increase; 95% confidence interval [CI]: 1.01-1.11; P = 0.011). In men with TVs ≥5 ml, larger TVs were associated with lower odds of sperm retrieval (adjusted OR: 0.84 per 1 ml increase; 95% CI: 0.71-0.98; P = 0.029). In conclusion, elevated serum FSH levels were associated with positive sperm retrieval in micro-TESE in NOA men with TVs <5 ml. In men with TV ≥5 ml, increases in average TVs were associated with lower odds of sperm retrieval.
