RESUMO
BACKGROUND: The number of donors from donation after circulatory determination of death (DCDD) has increased by at least 4-fold over the past decade. This study evaluated the association between the antecedent cardiac arrest status of controlled DCDD donors and the risk of delayed graft function (DGF). METHODS: Using data from the Australia and New Zealand Dialysis and Transplant, the associations between antecedent cardiac arrest status of DCDD donors before withdrawal of cardiorespiratory support, DGF, posttransplant estimated glomerular filtration rate (eGFR), and allograft loss were examined using adjusted logistic, linear mixed modeling, and cox regression, respectively. Among donors who experienced cardiac arrest, we evaluated the association between duration and unwitnessed status of arrest and DGF. RESULTS: A total of 1173 kidney transplant recipients received DCDD kidneys from 646 donors in Australia between 2014 and 2019. Of these, 335 DCDD had antecedent cardiac arrest. Compared with recipients of kidneys from donors without antecedent cardiac arrest, the adjusted odds ratio (95% confidence interval) for DGF was 0.85 (0.65-1.11) among those with kidneys from donors with cardiac arrest. There was no association between antecedent cardiac arrest and posttransplant eGFR or allograft loss. The duration of cardiac arrest and unwitnessed status were not associated with DGF. CONCLUSIONS: This focused analysis in an Australian population showed that the allograft outcomes were similar whether DCDD donors had experienced a prior cardiac arrest, with no associations between duration or unwitnessed status of arrest and risk of DGF. This study thus provides important reassurance to transplant programs and the patients they counsel, to accept kidneys from donors through the DCDD pathway irrespective of a prior cardiac arrest.
RESUMO
BACKGROUND: Adult hepatic mesenchymal hamartoma (HMH) is an extremely rare hepatic tumor. Recurrence following complete resection is uncommon. Liver transplantation (LT) is described as a possible treatment option in nonresectable HMH. We conducted a systematic review investigating LT in adult HMH followed by a case report describing evidence of extensive recurrence following complete resection of large right-sided HMH requiring LT. CASE REPORT: A 46-year-old woman with symptomatic large right-hepatic HMH underwent right hemi-hepatectomy with histologic evidence of complete resection. Two and a half years postresection, she presented with abdominal pain and distension; imaging revealed large multi-septated hepatic cystic lesions within the liver suggestive of extensive recurrence of disease with concerns of malignant sarcomatous transformation. After a multidisciplinary team discussion, the lesion was deemed unresectable and the patient was referred for LT. Findings on transplantation included giant multiple hepatic cystic lesions occupying the entire abdomen and histopathological analysis confirmed recurrent HMH with no malignancy. The 6-month follow-up was unremarkable with no signs of postoperative complications or rejection. CONCLUSION: We identified only 3 reported adult unresectable HMH cases in the English literature requiring LT, with good clinical outcome and no rejection on a 1-year follow-up. To our knowledge, we report the first recurrent HMH that required LT in the English literature. Current evidence suggests possible malignant sarcomatous transformation of those lesions. No guidelines exist on postresection surveillance for HMH; however, given their malignant potential, we suggest a benefit of imaging-based surveillance following HMH resection. Offering LT for nonresectable or recurrent HMH is a feasible treatment modality with a reported good outcome.

Abdominal angiography with selective arteriography and subsequent embolisation is an accepted management modality in the treatment of selected solid organ injuries following blunt abdominal trauma. This management practice is well established in the haemodynamically stable patient; however, this remains more controversial in haemodynamically compromised patients, though warrants consideration in both cases due to the associated benefits of non-operative management. This case report describes the successful non-operative management of a severe renal injury in a young polytraumatised patient following a high-speed motor vehicle crash. In addition, the rare CT diagnosis and management of an acute traumatic arteriocalcyeal fistula is discussed with a focus on the importance of renal parenchymal preservation.

Isolated gallbladder rupture following blunt thoracoabdominal trauma is rare; gall bladder rupture is seen in <1% of blunt abdominal trauma. This case report describes a significant mechanism of blunt force injury resulting in an isolated gallbladder rupture. Risk factors for traumatic gallbladder rupture are reviewed and the authors propose that a stiff, cirrhotic liver may exacerbate shear forces in the gallbladder fossa and represents an important risk factor for blunt gallbladder injury. Cholecystectomy remains the definitive management for gallbladder trauma. Almost all gallbladder injuries following blunt trauma are associated with other significant intra-abdominal injuries and in the setting of acute trauma, the authors recommend an open procedure to facilitate a detailed exploration of the peritoneal cavity to exclude associated injuries.

Serious intra-abdominal injuries are very uncommon in cricket; traumatic cricket injuries are traditionally musculoskeletal, soft tissue or maxillofacial in origin. The cause of such cricket injuries can be broadly divided into collision type injuries (a result of direct contact with the ball or bat, another player, the ground or boundary) or overuse injuries (due to running, throwing, batting, bowling, repetitive movements and overexertion). This case report describes a rare cause of small bowel perforation and suspected genitofemoral nerve injury secondary to the direct impact of a cricket ball, and includes a brief review of blunt abdominal injuries resulting in isolated small bowel perforations.
