Mesenteric aneurysm involves SMA/IMA branches; embolize/resect if large/ruptured; assess bowel perfusion.
普外科Celiac-trunk aneurysm is focal dilation of celiac artery; monitor, embolize/resect if large/ruptured.
普外科Popliteal aneurysm is focal dilation of popliteal artery; repair if large/thrombosed/embolic; screen contralateral/abdominal aorta.
普外科Femoral aneurysm is focal dilation of femoral artery; repair if large/symptomatic/thrombosed/embolic; pseudoaneurysm ultrasound-guided compression/embolization.
普外科ASO is lower-extremity atherosclerosis: claudication/rest pain/ulcer/gangrene; exercise, antiplatelet, risk-factor control, revascularization.
普外科Inclusion-body myositis is slowly progressive asymmetric distal/quadriceps weakness in older adults; no effective therapy, supportive/rehab.
普外科Subclavian-steal syndrome is vertebral-flow reversal from proximal subclavian stenosis: posterior-circulation symptoms + arm claudication; treat by vascular risk, revascularization.
普外科Hypermagnesemia is elevated serum magnesium: neuromuscular depression, hypotension, bradycardia, respiratory depression; usually in renal failure/excess Mg therapy; stop Mg, give calcium/dialysis.
普外科A thyroid nodule is a discrete lesion within the thyroid gland; mostly benign (colloid, adenoma, cyst), 5-15% malignant. Workup: TSH, ultrasound, fine-needle aspiration cytology.
普外科Wandering spleen is abnormal splenic mobility from lax/absent splenic suspensory ligaments, allowing the spleen to migrate. Risk: torsion and splenic necrosis. More common in women.
普外科Splenic infarction is ischemic necrosis of splenic tissue from splenic-artery/branch occlusion (embolus, thrombosis, sickle cell disease, endocarditis, hypercoagulability).
普外科Splenic cysts are true (epithelial-lined, congenital/parasitic) or pseudocysts (post-traumatic/post-infarct). Usually asymptomatic; large cysts cause left-upper-quadrant discomfort or rupture risk.
普外科Allergic vasculitis is a hypersensitivity small-vessel vasculitis caused by infection/drugs/chemicals, presenting with polymorphic skin lesions (purpura, papules, ulcers) and systemic symptoms.
普外科Thyroid tumors are benign or malignant. Benign include thyroid adenoma and cysts. >95% of malignant tumors are primary thyroid carcinoma; rare are malignant lymphoma and metastases. Histologically: papillary, follicular, anaplastic and medullary. Papillar
普外科Gallbladder cancer mostly affects women >50; men are fewer, female:male ≈34:1. Clinical picture: long history of chronic cholecystitis, sudden deterioration once cancer develops, persistent dull right-upper-quadrant pain, anorexia, nausea/vomiting; late j
普外科High-flow vascular malformation; abnormal embryonic vasculogenesis → direct arteriovenous anastomosis; no capillaries. 1.5% of vascular malformations; head/neck 50%; limbs/trunk next.
普外科Congenital; from mesodermal remnants; active endothelial sprouts → cords → canalized → connected to residual vessels. Self-contained vascular system.
普外科Common oral/maxillofacial benign tumor; congenital; endothelial proliferation. Facial skin/subcutis/oral mucosa (lip/tongue/cheek/floor of mouth). Capillary/cavernous/cirsoid types (first two common).
普外科Hamartoma; from submucosal vascular plexus/subserosal vessels. Hemangioma (true tumor: jejunum>ileum>duodenum) vs vascular malformation (arteriovenous dilation/tortuosity).
普外科Most common congenital benign tumor in infants; 1% in Mongoloids; rapid proliferation + spontaneous regression. From embryonic endothelial remnants; 60% in oral/maxillofacial region.
