Agenesis of Dorsal Pancreas and Solid Pseudopapillary Tumor: Ventral Pancreas Preserving Portal Vein Resection and Reconstruction Using a Peritoneal Graft.

A diabetic lady in her 40s was referred to surgical oncologists with epigastric pain associated with vomiting. Computed Tomography (CT) Abdomen with contrast demonstrated a mass arising from the head of the pancreas with the absence of dorsal pancreas, confirmed on magnetic resonance cholangio-pancreatography (MRCP). A core needle biopsy was done, and the tumor was revealed to be a solid pseudopapillary epithelial neoplasm. She underwent sub-total pancreatectomy preserving the duodenum and ventral pancreas as there was adequate free margin; however due to the tumor abutting the anterior wall of the portal vein, it was resected, and reconstruction was done using a peritoneal graft. The patient made a good recovery without any significant post-operative events.

Mycobacterium tuberculosis infection of an intralobar pulmonary sequestration.

Pulmonary sequestration is a rare bronchopulmonary foregut anomaly that occurs when a portion of the lung derives its blood supply from an aberrant vessel rather than the customary tracheobronchial supply. The sequestration can be classified as intralobar or extralobar. Most patients with intralobar sequestration are asymptomatic. Among symptomatic patients, presentations vary greatly, from fever, cough with expectoration, exertional dyspnea, pleuritic chest pain, and hemoptysis to eventual lung abscess or empyema. Contrast-enhanced computed tomography/computed tomography angiography is performed to determine the origin of the anomalous blood supply as well as the pathological manifestations involving the lobes. We present a patient with diagnosed intralobar sequestration who developed pulmonary tuberculosis of the sequestered lung tissue. The patient was successfully managed with long-term antitubercular therapy and left lower lobectomy with ligation of the anomalous vessel.

Central pulmonary artery histopathology in patients with cyanotic congenital heart diseases.

BACKGROUND: This study evaluated the pulmonary arterial (PA) wall histopathology and the risk factors related to histopathology and inadequate pulmonary artery growth in patients with cyanotic congenital heart diseases (CHDs) undergoing primary or second-stage operations after different types of systemic-to-PA shunts with or without pulmonary arterioplasty. METHODS: Operatively excised full-thickness PA tissue from 150 consecutive patients (mean age, 90.8 +/- 62.8 months; range, 6 months to 47 years) undergoing primary or second-stage procedures for different cyanotic CHDs were studied by light microscopy. The controls were 43 patients (23.8%) with normally developed central PAs and normal wall histology. RESULTS: The incidence of elastic fragmentation, increased ground substance, smooth muscle disarray, intimal thickening, and fibrosis was 61.3%, 36.6%, 34.6%, 39.3%, and 42% respectively. The risk of inadequate PA growth was 174.8, 64.7, and 45.5 times higher in patients with muscle disarray of the PA, abnormal lamellar count, and absence of palliative shunting procedures. CONCLUSIONS: Almost all PA walls in shunted patients undergoing primary/second-stage procedures for cyanotic CHD indicate significant lamellar loss and intrinsic pulmonary arteriopathy. These changes are present in infancy, are more pronounced in patients with deep cyanosis, and may account for or may coexist with a higher incidence of PA hypoplasia and inadequate PA growth encountered in these patients.

Successful lobectomy for pulmonary arteriovenous malformation causing recurrent massive haemoptysis.

A 6-year-old child with pulmonary arteriovenous malformation (PAVM) of the lower lobe of left lung was successfully treated by left lower lobectomy and the case is reported for its rarity. The exact diagnosis is relatively easy to make by contrast echocardiography and pulmonary angiocardiography, provided the possibility is entertained. Because of recurrent episodes of massive haemoptysis from a single pulmonary lobe, surgical resection was deemed the best curative option to avoid further episodes and recurrence. Published reports detailing coil embolisation therapy for PAVMs are also discussed.
